The document provides an overview of software testing and quality assurance. It discusses that testing checks for mistakes and defects, which are important to identify as some can be expensive or dangerous. Both static and dynamic testing methods are used to test software throughout its development lifecycle. The objectives of testing are to determine if software meets requirements, demonstrate it is fit for purpose, and detect defects. Root cause analysis seeks to understand why defects occur. Testing aims to find the right amount of testing based on risk rather than being completely exhaustive.

What is User Acceptance Testing? Also known as UAT or UAT testing.
it's basically, a process of verifying that a solution works for the user.
And the key word here, is user. This is crucial, because they’re the people who will use the software on a daily basis. There are many aspects to consider with respect to software functionality. There’s unit testing, functional testing, integration testing, and system testing, amongst many others.
What Is User Acceptance Testing?
I’ll keep it simple; according to Techopedia, UAT (some people call it UAT testing as well) is:
User acceptance testing (UAT) is the last phase of the software testing process. During UAT, actual software users test the software to make sure it can handle required tasks in real-world scenarios, according to specifications. UAT is one of the final and critical software project procedures that must occur before newly developed software is rolled out to the market.
User acceptance testing (UAT), otherwise known as Beta, Application, or End-User Testing, is often considered the last phase in the web development process, the one before final installation of the software on the client site, or final distribution of it.
The document describes the key stages of the software testing life cycle (STLC), including contract signing, requirement analysis, test planning, test development, test execution, defect reporting, and product delivery. It provides details on the processes, documents, and activities involved in each stage. Risk analysis and bug/defect management processes are also summarized. Various test metrics and bug tracking tools that can be used are listed.
Functional testing is a type of software testing that validates software functions or features based on requirements specifications. It involves testing correct and incorrect inputs to check expected behaviors and outputs. There are different types of functional testing including unit testing, integration testing, system testing, and acceptance testing. Testers write test cases based on requirements and specifications to test the functionality of software under different conditions.
The document provides an overview of software testing techniques and strategies. It discusses unit testing, integration testing, validation testing, system testing, and debugging. The key points covered include:
- Unit testing involves testing individual software modules or components in isolation from the rest of the system. This includes testing module interfaces, data structures, boundary conditions, and error handling paths.
- Integration testing combines software components into clusters or builds to test their interactions before full system integration. Approaches include top-down and bottom-up integration.
- Validation testing verifies that the software meets the intended requirements and customer expectations defined in validation criteria.
- System testing evaluates the fully integrated software system, including recovery, security, stress,
The V-model is a software development lifecycle model where each phase of the development process is validated by an equivalent phase of testing. It emphasizes testing at each development stage. In the V-model, testing begins during the requirements analysis phase, and each subsequent development phase is tested before moving further down the V, and development and testing phases occur in parallel. The benefits of the V-model include preventing faults, avoiding downward flow of defects, lower rework costs, improved quality and risk management.

This document provides an introduction to software testing fundamentals. It discusses why testing is important to find defects, how testing promotes quality, and how testing fits into quality assurance. It defines key terms like bug, defect, error, failure, fault, and explains causes of software defects. It discusses when defects arise and the costs of defects. It also covers the role of testing in software development and maintenance, how testing relates to quality, and challenges around determining how much testing is needed. Finally, it discusses using defect data to plan tests and how testing aims to improve quality but can never prove a system is completely defect-free.
This document provides an introduction to fundamentals of testing. It discusses why testing is necessary, explaining that human errors can introduce defects at any stage of development that may later cause failures. Testing helps reduce risks by finding defects, especially early ones which are cheaper to fix. The document also distinguishes between defects, failures, and their causes/effects. It notes testing is part of quality assurance and helps improve quality by providing confidence if few defects are found through rigorous testing.
In this chapter, we will introduce you to the fundamentals of testing: why testing is needed; its limitations, objectives and purpose; the principles behind testing; the process that testers follow; and some of the psychological factors that testers must consider in their work. By reading this chapter you'll gain an understanding of the fundamentals of testing and be able to describe those fundamentals.
The document discusses defect reporting and tracking. It defines a software bug and explains that once a tester identifies a defect, they generate a formal defect report. The report includes information like a unique ID, project name, summary, steps to reproduce, actual and expected results. A bug goes through different statuses in its lifecycle from new to closed. Developers analyze and fix bugs, while testers verify fixes and may reopen bugs. Bug tracking systems help teams manage large numbers of defects by keeping track of key details for each bug report.
Software testing is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. I hope this ppt will help u to learn about software testing.

This document discusses fundamentals of software testing. It explains that testing is important to identify defects that can cause problems. Testing helps measure software quality by finding bugs and ensuring requirements are met. However, exhaustive testing of all possible inputs is impossible, so risk-based testing is used instead. Testing activities should start early and continue through the software development life cycle. The goal of testing is to reduce risks and improve the software, not just find defects.
ISTQB Chapter 1 Fundamentals of Testingssuser2d9936
Software testing is a process of validating and verifying software to ensure it meets requirements and works as expected. It takes place throughout the software development lifecycle. Testing helps prevent defects from being introduced into code and catch any issues. Software testing is necessary because even with careful development, mistakes can be made, so independent testing helps identify flaws. The objectives of testing include finding defects, gaining confidence in quality, preventing defects, and ensuring requirements are met.
The document provides an overview of software testing concepts including definitions of software, types of software, the software development lifecycle, and principles of software testing. It defines software as a set of instructions that operate computers and defines system software and application software. It discusses the importance of testing in finding defects and outlines seven principles of software testing including that exhaustive testing is not possible, early testing is important, and testing is context dependent. It also provides an analogy comparing software testing to driving tests.
Fundamentals of testing what is testing (reference graham et.al (2006))Alfarizi ,S.Kom
The document discusses software testing, its objectives, and its importance. It uses an analogy to a driving test to explain software testing. Some key points made:
1) Testing helps find defects, provide confidence in quality, and prevent defects, similar to how a driving test evaluates a driver's skills.
2) Both static and dynamic testing provide information to improve the system and development/testing processes.
3) Over time, as processes improve, dynamic testing finds fewer defects while static testing finds more early on.
Fundamentals of Testing - Andika Dwi Ary CandraAnd11ka
1. The document introduces software testing fundamentals, defining key terms like defect, error, failure, and quality.
2. It explains that testing is necessary to find software defects that can cause problems, and that the cost of fixing defects rises significantly if found later in the development process.
3. The roles of testing are to identify defects during development and maintenance to reduce failures and improve quality in operations. Rigorous testing helps deliver software that meets specifications and customer needs.
This paper describes the different techniques of testing the software. This paper explicitly addresses the idea for testability and the important thing is that the testing itself-not just by saying that testability is a desirable goal, but by showing how to do it. Software testing is the process we used to measure the quality of developed software. Software Testing is not just about error-finding and their solution but also about checking the client requirements and testing that those requirements are met by the software solution. It is the most important functional phase in the Software Development Life Cycle(SDLC) as it exhibits all mistakes, flaws and errors in the developed software. Without finding these errors, technically termed as ‘bugs,’ software development is not considered to be complete. Hence, software testing becomes an important parameter for assuring quality of the software product. We discuss here about when to start and when to stop the testing of software. How errors or Bugs are formed and rectified. How software testing is done i.e. with the help of Team Work.
This document discusses the fundamentals of software testing, including why testing is needed, its limitations and objectives. It explains that while people may check their own work, they are more likely to miss their own mistakes, so testing by others is important. It also discusses some of the common causes of software defects like errors in specification, design and implementation or environmental conditions. Finally, it talks about the role of testing in software development, maintenance and operations to meet standards and help measure quality.
1. Software defects can range from minor annoyances to serious issues that endanger health and safety or the environment if a software program miscalculates important information.
2. Defects in software are caused when mistakes are made during the design and development of the software by programmers. Not all defects result in failures, and some may remain dormant without being detected.
3. Software testing is a process that involves planning what will be tested, preparing test cases, executing tests, evaluating results, and determining if the software is ready based on exit criteria and requirements. Both code and documentation need to be tested to fully evaluate the software.
This document provides an overview of software testing fundamentals. It discusses why testing is needed given that people make mistakes in both developing and using software. It also covers common causes of software defects like errors in specification, design, implementation, and use. Additionally, it discusses how testing helps measure quality by finding defects and increasing confidence in the system. Testing aims to reduce risks and meet standards, with higher risk industries requiring more rigorous testing.
This document discusses several key principles and concepts related to software testing:
1) Testing is context dependent and different types of software require different testing approaches. For example, safety critical software needs more rigorous testing than an e-commerce site.
2) Human errors can introduce defects during any stage of the software development life cycle, from requirements to maintenance. Thorough testing is needed to identify and reduce defects.
3) Exhaustive testing all possible combinations of inputs and conditions is not feasible except for simple cases. Risk-based prioritization is used to guide focused testing efforts.

Quality Patents: Patents That Stand the Test of TimeAurora Consulting
Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality.
Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality.
Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality.
Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank?

Best Practices for Effectively Running dbt in Airflow.pdfTatiana Al-Chueyr
As a popular open-source library for analytics engineering, dbt is often used in combination with Airflow. Orchestrating and executing dbt models as DAGs ensures an additional layer of control over tasks, observability, and provides a reliable, scalable environment to run dbt models.
This webinar will cover a step-by-step guide to Cosmos, an open source package from Astronomer that helps you easily run your dbt Core projects as Airflow DAGs and Task Groups, all with just a few lines of code. We’ll walk through:
- Standard ways of running dbt (and when to utilize other methods)
- How Cosmos can be used to run and visualize your dbt projects in Airflow
- Common challenges and how to address them, including performance, dependency conflicts, and more
- How running dbt projects in Airflow helps with cost optimization

2. When we are testing something we are checking whether it is OK.
Testing is necessary because we all make mistakes.
Some of those mistakes are unimportant, but some of them are expensive
or dangerous.
Because we should assume our work contains mistakes, we all need to
check our own work.
However, some mistakes come from bad assumptions and blind spots, so
we might make the same mistakes when we check our own work as we
made when we did it.
So we should get someone else to check our work.
3. Nowadays almost everyone is aware of softwares.
We encounter them in our homes, at work, while shopping etc.
However, most people have had an experience with software that did not
work as expected.
Not all software systems carry the same level of risk and not all problems
have the same impact when they occur.
A risk is something that has not happened yet and it may never happen; it
is a potential problem.
We are concerned about these potential problems because, if one of them
did happen, we'd feel a negative impact.
When we discuss risks, we need to consider how likely it is that the
problem would occur and the impact if it happens.
Some of the problems we encounter when using software are quite trivial,
but others can be costly and damaging - with loss of money, time or
business reputation - and even may result in injury or death.
For example, suppose a user interface has typographical defects. It may be
trivial, but it could have a significant effect, depending on the website and
the defect.
4. If someone makes an error or mistake in using the software, this may lead
directly to a problem - the software is used incorrectly and so does not
behave as we expected.
However, people also design and build the software and they can make
mistakes during the design and build.
These mistakes mean that there are flaws in the software itself. These are
called defects or sometimes bugs or faults.
When the software code has been built, it is executed and then any defects
may cause the system to fail to do what it should do (or do something it
shouldn't), causing a failure.
Not all defects result in failures; some stay dormant in the code and we
may never notice them.
5. DO OUR MISTAKES MATTER?
◦ Any human being, programmers and testers included, can make an error.
◦ These errors may produce defects in the software code or system, or in a
document.
◦ If a defect in code is executed, the system may experience a failure.
◦ So the mistakes we make matter partly because they have consequences for the
products for which we are responsible.
◦ Defects in software, systems or documents may result in failures, but not all
defects do cause failures.
◦ It is not just defects that give rise to failure.
◦ Failures can also be caused by environmental conditions as well: for example, a
radiation burst, a strong magnetic field, electronic fields, or pollution could
cause faults in hardware or firmware.
◦ Failures may also arise because of human error in interacting with the software,
perhaps a wrong input value being entered or an output being misinterpreted.
◦ Finally, failures may also be caused by someone deliberately trying to cause a
failure in a system - malicious damage.
8. Rigorous testing is necessary during development and maintenance to
identify defects, in operational environment and increase the quality of the
operational system.
This includes looking for places in the user interface where a user might
make a mistake in input of data or in the interpretation of the output, and
looking for potential weak points for intentional and malicious attack.
Executing tests help us move towards improved quality of product and
service, but that is just one of the verification and validation methods
applied to the products.
Processes are also checked, for example by audit.
A variety of methods may be used to check work, some of which are done
by the author of the work and some by others to get an independent view.
We may also be required to carry out software testing to meet contractual
or legal requirements, or industry specific standards.
These standards specify what kind of techniques we must use, or the
percentage of software code that must be exercised.
9. Testing helps us to measure the quality of software in terms of number of
defects found, the tests run and the system covered by the tests.
Testing can give confidence in the quality of software if it finds few or no
defects, provided we are happy that the testing is sufficiently rigorous.
A poor test may uncover few defects and may leave us with a false sense of
security.
A well designed test will uncover defects if they are present and so, if such
a test passes we will rightly be more confident in the software and be able
to assert that the overall level of risk to use the system has been reduced.
WHAT IS QUALITY?
◦ Projects aim to deliver software to specification.
◦ For the project to deliver what the customer needs requires a correct
specification.
◦ Additionally the delivered system must meet the specification. This is known as
verification and validation.
10. ◦ As well as wanting the right software system built correctly, the customer wants
the project to be within budget and timescale.
◦ It is important that the project team, the customers and any other stakeholders set
and agree expectations.
◦ We need to understand what the customers understand by quality and what their
expectations are.
◦ What we as software developers see as quality- that the software meets its
defined software specifications, is technically excellent and has few bugs in it-
may not provide a quality solution to the customer.
◦ Furthermore if our customers feel that they have spent more money than they
wanted or that the software does not help them carry out their tasks, they wont
be impressed by the technical excellence of the solution.
WHAT IS ROOT CAUSE ANALYSIS?
◦ When we detect failures, we might try to track them back to their root cause, the
real reason that they happened.
◦ There are several ways of carrying out root cause analysis, often involving a
group brainstorming ideas and discussing them.
11. ◦ Understanding the root causes of defects is an important aspect of quality
assurance activities, and testing contributes by helping us to identify defects as
early as possible before the software is in use.
◦ As testers, we are also interested in looking at defects found in other projects, so
that we can improve our processes.
HOW MUCH TESTING IS ENOUGH?
◦ We have a choice: test everything, test nothing or test some of the software.
◦ The immediate response would be ‘Everything must be tested’ because we don’t
want to use software that is not tested completely.
◦ This implies that we must test all aspects of a software system.
◦ What we must consider is that whether we must or even can test completely.
◦ Pressures on a project include time and budget as well as pressure to deliver a
technical solution that meets the customers' needs.
◦ Customers and project managers will want to spend an amount on testing that
provides a return on investment for them.
◦ This return on investment includes preventing failures after release that are
costly.
◦ Testing completely - even if that is what customers and project managers ask for
- is simply not what they can afford.
◦ Instead we need a test approach which provides the right amount of testing for
this project, these customers (and other stakeholders) and this software.
◦ We do this by aligning the testing we do with the risks for the customers, the
stakeholders, the project and the software.
12. THE DRIVING TEST – AN ANALOGY FOR SOFTWARE TESTING
In a driving test, the examiner critically assesses the candidate's driving,
noting every mistake, large or small, made by the driver under test.
The examiner takes the driver through a route which tests many possible
driving activities, such as road junctions of different types, control and
maneuvering of the car, ability to stop safely in an emergency, and
awareness of the road, other road users and hazards. Some of the activities
must be tested.
The examiner bases the judgment on the number and severity of the
failures identified, and also whether the driver has been able to meet the
driving requirements.
A single severe fault is enough to fail the whole test, but a small number of
minor faults might still mean the test is passed.
Many minor faults would reduce the confidence of the examiner in the
quality —of the driving to the point where the driver cannot pass.
13. The definition is broken down into parts; the definition has some key
phrases to remember. The definition starts with a description of testing as a
process and then lists some objectives of the test processes.
Testing as a process:
◦ Process - Testing is a process rather than a single activity - there are a series of
activities involved.
◦ All life cycle activities – Testing as a process takes place throughout the software
development life cycle. We saw earlier that the later in the life cycle we find
bugs, the more expensive they are to fix.
◦ Both static and dynamic -as well as tests where the software code is executed to
demonstrate the results of running tests (often called dynamic testing) we can
also test and find defects without executing code. This is called static testing.
This testing includes reviewing of documents (including source code) and static
analysis. This is a useful and cost effective way of testing.
◦ Planning - Activities take place before and after test execution. We need to
manage the testing; for example, we plan what we want to do; we control the test
activities; we report on testing progress and the status of the software under test;
and we finalize or close testing when a phase completes.
14. ◦ Preparation – We need to choose what testing we’ll do, by selecting test
conditions and designing test cases.
◦ Evaluation – As well as executing the tests, we must check the results and
evaluate the software under test and the completion criteria, which help us
decide whether we have finished testing and whether the software product has
passed the tests.
◦ Software products and related work products – We don’t just test code. We test
the design and requirement specifications, and we test related documents such as
operation, user and training material.
The second part of the definition covers some of the objectives for testing-
the reasons why we do it.
◦ Determine that software products satisfy specified requirements
◦ Demonstrate that software products are fit for purpose
◦ Detect defects
15. The driving examiner becomes the software tester. The driver being
examined becomes the system or software under test.
Planning and preparation – Both the examiner and the tester need a plan
of action and need to prepare for the test, which is not exhaustive, but is
representative and allows risk – based decisions about the outcome.
Static and dynamic – Both dynamic (driving the car or executing the
software) and static(questions to the driver or review of the software) tests
are useful.
Evaluation – The examiner and the tester must make an objective
evaluation, log the test outcome and report factual observations about the
tests.
Determine that they satisfy specified requirements – The examiner and the
tester both check against requirements to carry out particular tasks
successfully.
16. Demonstrate that they are fit for purpose – The examiner and the tester
are not evaluating for perfection but for meeting sufficient attributes
required to pass the test.
Detect defects – The examiner and tester both look for and log faults.
17. We can use both static and dynamic testing as means for achieving similar
test objectives. Both provide information to improve both the system to be
tested , and the development and testing processes.
Testing often includes the following goals and objectives:
◦ Finding defects
◦ Gaining confidence in and providing information about the level of quality
◦ Preventing defects
Many types of review and testing activities take place at different stages in
the life cycle. These have different objectives.
Early testing- such as early test design and review activities – finds defects
early on when they are cheap to find and fix.
Fixing the defects may not always be the test objective or the desired
outcome. Sometimes we simply want to gather information and measure
the software.
18. When maintaining software by enhancing it or fixing bugs, we are
changing software that is already being used. In that case an objective of
testing may be to ensure that we have not made errors and introduced
defects when we changed the software. This is called regression testing.
We may continue to test the system once it is in operational use. In this
case, the main objective may be to assess the system characteristics such
as reliability or availability.
19. Reviewing defects and failures in order to improve processes allows us to
improve our testing and our requirements, design and development
processes.
One phenomenon that many testers have observed is that defects tend to
cluster.
Testers will often use this information when making their risk assessment
for planning the tests, and will focus on known hot spots.
A main focus of reviews and other static tests is to carry out testing as early
as possible, finding and fixing defects more cheaply, and preventing
defects from appearing at later stages of the project.
These activities help us find out about defects earlier and identify potential
clusters.
Additionally, an important outcome of all testing is information that assists
in risk assessment; these reviews will contribute to the planning for the
tests executed later in the software development life cycle.
20. Over time, as we improve our whole software development life cycle and
the early static testing, we may well find that dynamic test levels find fewer
defects.
As the hot spots for bugs get cleaned up we need to move our focus
elsewhere, to the next set of risks.
Over time, our focus may change from finding coding bugs, to looking at
the requirements and design documents for defects, and to looking for
process improvements so that we prevent defects in the product.
21. When a test finds a defect that must be fixed, a programmer must do some
work to locate the defect in the code and make the fix.
In this process called debugging, a programmer will examine the code for
the immediate cause of the problem, repair the code and check that the
code now executes as expected.
The fix is often then tested separately to confirm the fix.
22. This principle arises from the theory of the process of scientific
experimentation and has been adopted by testers.
It says, however many white swans we see, we cannot say ‘All swans are
white’. However, as soon as we see one black swan we can say ‘Not all
swans are white’.
In the same way, however many tests we execute without finding a bug, we
have not shown ‘There are no bugs’. As soon as we find a bug, we have
shown ‘This code is not bug-free’.
23. Testing shows presence of defects
Exhaustive testing is impossible
Early testing
Defect clustering
Pesticide paradox
◦ If the same tests are repeated over and over again, eventually the same set of test
cases will no longer find any new bugs. To overcome this 'pesticide paradox', the
test cases need to be regularly reviewed and revised, and new and different tests
need to be written to exercise different parts of the software or system to
potentially find more defects.
Testing is context dependent
◦ Testing is done differently in different contexts. For eg., safety – critical
software is tested differently from an e-commerce site.
Absence of errors fallacy
◦ Finding and fixing defects does not help if the system built is unusable and does
not fulfill the users’ needs and expectations.
24. The activities in the fundamental test process are divided into the following
basic steps:
◦ Planning and Control;
◦ Analysis and Design;
◦ Implementation and Execution;
◦ Evaluating exit criteria and Reporting;
◦ Test closure activities.
25. Test planning has the following major tasks, which help us build a test
plan:
◦ Determine the scope and risks and identify the objectives of testing.
◦ Determine the test approach.
◦ Implement the test policy and/or the test strategy
◦ Determine the required test resources
◦ Schedule test analysis and design tasks, test implementation , execution and
evaluation.
◦ Determine the exit criteria. This will show us which tasks and checks we must
complete for a particular level of testing before we can say that testing is
finished.
Management of any activity does not stop with planning it. We need to
control and measure progress against the plan. So test control is an
ongoing activity.
Test control has the following major tasks:
◦ Measure and analyze the results of reviews and testing.
◦ Monitor and document progress test coverage and exit criteria
◦ Provide information on testing.
26. Initiate corrective actions: For example, tighten exit criteria for defects
fixed, ask for more effort to be put into debugging or prioritize defects for
fixing test blockers.
Make decisions: Based on the measures and information gathered during
testing and any changes to business and project risks or our increased
understanding of technical and product risks, we'll make decisions or
enable others to make decisions: to continue testing, to stop testing, to
release the software or to retain it for further work for example.
27. During test analysis and design, we take general testing objectives
identified during planning and build test designs and test procedures.
Test analysis and design has the following major tasks:
◦ Review the test basis (such as the product risk analysis, requirements,
architecture, design specifications, and interfaces), examining the specifications
for the software we are testing. We use the test basis to help us build our tests.
◦ Identify test conditions based on analysis of test items, their specifications, and
what we know about their behavior and structure.
◦ Design the tests, using techniques to help select representative tests that relate to
particular aspects of the software which carry risks or which are of particular
interest, based on the test conditions and going into more detail.
◦ Evaluate testability of the requirements and system. The requirements may be
written in a way that allows a tester to design tests.
◦ Design the test environment set-up and identify any required infrastructure and
tools.
28. During test implementation and execution, we take the test conditions and
make them into test cases and set up the test environment.
Test implementation and execution has the following major tasks:
IMPLEMENTATION
◦ Develop and prioritize our test cases, and create test data for those tests. We will
also write instructions for tests.
◦ Create test suites from the test cases for efficient test execution. A test suite is a
logical collection of test cases which naturally work together. We’ll also set up a
test execution schedule.
◦ Implement and verify the environment. We make sure that the test environment
has been set up correctly, possibly even running specific tests on it.
EXECUTION
◦ Execute the test suites and individual test cases, following our test procedures.
◦ Log the outcome of test execution and record the identities and versions of the
software under test, test tools and testware.
◦ Compare actual results (what happened when we ran the tests) with expected
results (what we anticipated would happen).
29. ◦ Where there are differences between actual and expected results, report
discrepancies as incidents.
◦ Repeat test activities as a result of action taken for each discrepancy. We need to
re-execute tests that previously failed in order to confirm a fix.
30. Evaluating exit criteria is the activity where test execution is assessed
against the defined objectives. This should be done for each test level, as
for each we need to know whether we have done enough testing.
Evaluating exit criteria has the following major tasks:
◦ Check test logs against the exit criteria specified in test planning: We look to see
what evidence we have for which tests have been executed and checked, and
what defects have been raised, fixed, confirmation tested, or are outstanding.
◦ Assess if more tests are needed or if the exit criteria specified should be
changed.
◦ Write a test summary report for stakeholders: It is not enough that the testers
know the outcome of the test. All the stakeholders need to know what testing has
been done and the outcome of the testing, in order to make informed decisions
about the software.
31. During test closure activities, we collect data from completed test activities
to consolidate experience, including checking and filing testware, and
analyzing facts and numbers.
Test closure activities include the following major tasks:
◦ Check which planned deliverables we actually delivered and ensure all incident
reports have been resolved through defect repair or deferral.
◦ Finalize and archive testware, such as scripts, the test environment, and any
other test infrastructure, for later reuse.
◦ Hand over testware to the maintenance organization who will support the
software and make any bug fixes or maintenance changes, for use in
confirmation testing and regression testing.
◦ Evaluate how the testing went and analyze lessons learned for future releases
and projects.
32. Independent Testing- Who is a tester?
The mindset we want to use while testing and reviewing is different from
the one we use while analyzing or developing.
By this we mean that, if we are building something we are working
positively to solve problems in the design and to realize a product that
meets some need.
However, when we test or review a product, we are looking for defects in
the product and thus are critical of it.
We do not mean that a tester cannot be a programmer, or that a programmer
cannot be a tester, although they often are separate roles.
In fact, programmers are testers - they test the components which they
build, and the integration of the components into the system.
With the right mindset, programmers can test their own code; indeed
programmers do test their own code and find many problems, resolving
them before anyone else sees the code.
33. However, we all know it is difficult to find our own mistakes.
So programmers often rely on others to help test their work. This other
person might be a fellow analyst, designer or developer. A person who will
use the software may help test it.
Testing specialists - professional testers – are often involved. In fact,
testing may involve a succession of people each carrying out a different
level of testing. This allows an independent test of the system.
Several levels of independence can be identified, listed here from the
lowest level of independence to the highest:
◦ tests by the person who wrote the item under test;
◦ tests by another person within the same team, such as another programmer;
◦ tests by a person from a different organizational group, such as a independent
test team;
◦ tests designed by a person from a different-organization or company, such as
outsourced testing or certification by an external body.
