Now to answer, “What is Testing?” we can go by the famous definition of Myers, which says, “Testing is the process of executing a program with the intent of finding errors”
In this presentation, we will review the fundamental concepts of Software Development Life Cycle (SDLC) and Software test life Cycle (STLC) throughout the traditional development methodologies.

Testing software is conducted to ensure the system meets user needs and requirements. The primary objectives of testing are to verify that the right system was built according to specifications and that it was built correctly. Testing helps instill user confidence, ensures functionality and performance, and identifies any issues where the system does not meet specifications. Different types of testing include unit, integration, system, and user acceptance testing, which are done at various stages of the software development life cycle.
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.
The document outlines the software testing life cycle (STLC) which is a systematic and planned process for testing software. The STLC includes requirement analysis to define what will be tested, test planning to identify activities, resources and schedules, test case development to detail test cases and data, test execution to run test cases and log results, and test cycle closure to generate reports and complete testing.

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,
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 goal of STLC is to systematically test software through a planned process to improve quality.
BugRaptors provide Software testing is entirely about finding defects in applications, right? Apparently, this can be considered as the principal goal of all the QA practices. However, all the defects diverge from each other. It cannot be stated if some are more important than others, yet it’s possible to locate and fix them all.
The document describes the testing life cycle process which includes test plan preparation, test case design, test execution and log preparation, defect tracking, and test report preparation. It then provides details about each step of the testing life cycle process such as how to prepare test plans, design test cases, execute tests and log results, track defects, and prepare test reports.

Systemic barriers to the fight against corruption newSYCHRISTO
The fight against corruption has become increasingly sophisticated and such demands a well-integrated, multidisciplinary
strategy. This has necessitated the establishment of anti-corruption institutions, agencies or
commissions which invariably have one or more of three functions: investigation and enforcement; corruption
prevention; and awareness and education. However in Ghana, despite the existence of anti-corruption
institutions, the perception of corruption has steadily increased to overwhelming levels. Why the increase in
corruption in the face of these anti-corruption institutions is the subject matter of this study. This study brings to
fore the systemic barriers, their frequency of occurrence and magnitude. This study aimed at identifying the
challenges that affect the effectiveness of these anti-corruption institutions in Ghana. The study was purposely
carried out within anti-corruption institutions in Ghana. A simple random probability sampling was employed in
sampling nine (9) anti-corruption institutions in the Ashanti Region of Ghana and questionnaires administered to
their administrative heads. Relative importance, frequency and severity equations were used to analyze and rank
the challenges affecting the work of these institutions. Lack of political will and inadequate leadership and
management with Relative importance Index RII of 0.9778 respectively were the two (2) most critical
challenges affecting the effectiveness of anti-corruption institutions in Ghana. Lack of donor initiatives with RII
of 0.6667 was considered as the least challenge. The most frequent challenge identified by the anti-corruption
agencies was the lack of budget and fiscal autonomy, with an index of 0.8148. In the face of these challenges,
the government of Ghana should improve upon its efforts at fighting corruption as it strengthens the various
anti-corruption institutions financially and logistically.
Testing is the process of evaluating a system or its components to identify differences between expected and actual results. It involves executing a system to identify gaps, errors, or missing requirements. There are different types of testing such as unit testing, integration testing, system testing, and acceptance testing. Testing can be manual, automated, functional, or non-functional. Functional testing evaluates system functionality while non-functional testing evaluates attributes like performance and security. Common non-functional test types are load testing and stress testing which analyze a system's behavior under different load conditions.

Testing is important to ensure software quality by validating requirements and identifying bugs. There are different types of testing such as static and dynamic testing. Static testing involves manual reviews of documents while dynamic testing executes the code. Testing can be done from different perspectives such as black box, white box, and grey box. Different testing techniques are applied at various stages like unit, integration, and system testing. Testing also aims to validate functionality as well as non-functional aspects. Domain knowledge is critical for effective manual testing.
This document provides an overview of various types of software testing techniques, including static testing, dynamic testing, regression testing, usability testing, and accessibility testing. Static testing involves evaluating code and documentation without executing the program, while dynamic testing assesses software performance and functionality by executing it under different conditions. Regression testing verifies that new code changes do not negatively impact existing features. Usability and accessibility testing evaluate how real users interact with a product to complete tasks.

Software development... for all? (keynote at ICSOFT'2024)miso_uam
Our world runs on software. It governs all major aspects of our life. It is an enabler for research and innovation, and is critical for business competitivity. Traditional software engineering techniques have achieved high effectiveness, but still may fall short on delivering software at the accelerated pace and with the increasing quality that future scenarios will require.
To attack this issue, some software paradigms raise the automation of software development via higher levels of abstraction through domain-specific languages (e.g., in model-driven engineering) and empowering non-professional developers with the possibility to build their own software (e.g., in low-code development approaches). In a software-demanding world, this is an attractive possibility, and perhaps -- paraphrasing Andy Warhol -- "in the future, everyone will be a developer for 15 minutes". However, to make this possible, methods are required to tweak languages to their context of use (crucial given the diversity of backgrounds and purposes), and the assistance to developers throughout the development process (especially critical for non-professionals).
In this keynote talk at ICSOFT'2024 I presented enabling techniques for this vision, supporting the creation of families of domain-specific languages, their adaptation to the usage context; and the augmentation of low-code environments with assistants and recommender systems to guide developers (professional or not) in the development process.

5. Black box and White box testing
Black-box test design treats the system as a literal "black-box", so it doesn't explicitly use knowledge
of the internal structure. It is usually described as focusing on testing functional requirements.
Synonyms for black-box include: behavioral, functional, opaque-box, and closed-box.
White-box test design allows one to peek inside the "box", and it focuses specifically on using internal
knowledge of the software to guide the selection of test data. It is used to detect errors by means of
execution-oriented test cases. Synonyms for white-box include: structural, glass-box and clear-box.
While black-box and white-box are terms that are still in popular use, many people prefer the terms
"behavioral" and "structural". Behavioral test design is slightly different from black-box test design
because the use of internal knowledge isn't strictly forbidden, but it's still discouraged. In practice, it
hasn't proven useful to use a single test design method. One has to use a mixture of different
methods so that they aren't hindered by the limitations of a particular one. Some call this "gray-box"
or "translucent-box" test design, but others wish we'd stop talking about boxes altogether!!!
6. GUI testing
GUI is the abbreviation for Graphic User Interface. It is absolutely essential that any application has to be
user-friendly. The end user should be comfortable while using all the components on screen and the
components should also perform their functionality with utmost clarity. Hence it becomes very
essential to test the GUI components of any application. GUI Testing can refer to just ensuring that
the look-and-feel of the application is acceptable to the user, or it can refer to testing the functionality
of each and every component involved.
The following is a set of guidelines to ensure effective GUI Testing and can be used even as a checklist
while testing a product / application.

2.1 Validation, 2.2 Navigation, 2.3 Usability, 2.4 Data Integrity, 2.5 Modes (Editable Read-only),
2.6 General,
7. Regression Testing
Regression testing is the process of testing changes to computer programs to make sure that the
older programming still works with the new changes.
Regression testing is a normal part of the program development process. Test department coders
develop code test scenarios and exercises that will test new units of code after they have been
written.
Before a new version of a software product is released, the old test cases are run against the new
version to make sure that all the old capabilities still work. The reason they might not work because
changing or adding new code to a program can easily introduce errors into code that is not intended
to be changed.
The selective retesting of a software system that has been modified to ensure that any bugs have
been fixed and that no other previously working functions have failed as a result of the reparations
and that newly added features have not created problems with previous versions of the software. Also
referred to as verification testing
Regression testing is initiated after a programmer has attempted to fix a recognized problem or has
added source code to a program that may have inadvertently introduced errors.
It is a quality control measure to ensure that the newly modified code still complies with its specified
requirements and that unmodified code has not been affected by the maintenance activity.
8. Phases of Testing
The Primary objective of testing effort is to determine the conformance to
requirements specified in the contracted documents. The integration of this code
with the internal code is the important objective. Goal is to evaluate the system as
a whole, not its parts
Techniques can be structural or functional.
Techniques can be used in any stage that tests the system as a whole (System
testing ,Acceptance Testing, Unit testing, Installation, etc.)
Phases of testing...
9. Integration testing
Integration testing tests integration or interfaces between components, interactions to different parts of
the system such as an operating system, file system and hardware or interfaces between systems.
Also after integrating two different components together we do the integration testing. As displayed in
the image below when two different modules ‘Module A’ and ‘Module B’ are integrated then the
integration testing is done.
What is IntegrationTesting
Integration testing is done by a specific integration tester or test team.
Integration testing follows two approach known as ‘Top Down’ approach and ‘Bottom Up’
approach as shown in the image below:
10. Integration testing
1. Big Bang integration testing:
2. Top-down integration testing:
3. Bottom-up integration testing:
11. Acceptance testing
In software engineering, acceptance testing is formal testing conducted to determine whether a system
satisfies its acceptance criteria and thus whether the customer should accept the system.
The main types of software testing are:
Component, Interface, System, Acceptance, Release.
Acceptance Testing checks the system against the "Requirements".
Hence the goal of acceptance testing should verify the overall quality, correct operation, scalability,
completeness, usability, portability, and robustness of the functional components supplied by the
Software system.
Severity Levels :-
These levels will range from (say) 1 to 6 and will represent the relative severity, in terms of business /
commercial impact, of a problem with the system, found during testing. Here is an example which has
been used successfully; '1' is the most severe; and '6' has the least impact :-
Show Stopper - It is impossible to continue with the testing because of the severity of this error / bug
Critical Problem - Testing can continue but we cannot go into production (live) with this problem
12. Continued...
Major Problem - Testing can continue but live this feature will cause severe disruption to business
processes in live operation
Medium Problem - Testing can continue and the system is likely to go live with only minimal departure
from agreed business processes
Minor Problem - Both testing and live operations may progress. This problem should be corrected, but
little or no changes to business processes are envisaged
'Cosmetic' Problem - Colours, fonts, pitch size However, if such features are key to the business
requirements they will warrant a higher severity level.
13. System testing
In system testing the behavior of whole system/product is tested as defined by the scope of the
development project or product.
It may include tests based on risks and/or requirement specifications, business process, use cases, or
other high level descriptions of system behavior, interactions with the operating systems, and system
resources.
System testing is most often the final test to verify that the system to be delivered meets the
