A software review is a process where software products are examined by various parties to provide feedback or approval. There are three main categories of reviews: peer reviews conducted by colleagues to evaluate technical quality; management reviews conducted by managers to evaluate progress; and audit reviews conducted by external personnel to evaluate compliance. Common types of reviews include code reviews, inspections, walkthroughs, and technical reviews. The generic IEEE review process involves entry evaluation, planning, preparation, group examination, rework, and exit evaluation to systematically identify defects early in the development process when they are least costly to fix.
The document discusses software inspection, which involves reviewing software artifacts like analysis, designs, and code with others besides the original developer. Inspections aim to find errors early in development. An inspection team consists of 3-8 members filling roles like moderator, author, reader, and recorder. Benefits include new perspectives finding flaws, knowledge sharing, and catching defects early to reduce rework and testing effort. Studies found inspections can reduce "rework" costs by 50% and save 20 hours of testing for every 1 hour spent inspecting.
The document discusses static testing techniques, which involve examining software work products like requirements and code manually or with tools, without executing the software. It covers topics like formal reviews, roles in reviews, types of reviews including walkthroughs, inspections and technical reviews. It also discusses using static analysis tools to check for adherence to coding standards and metrics. There are multiple choice questions at the end to test understanding of reviews and static analysis.
This document summarizes generative adversarial networks (GANs) and their applications.

It also shows how to define relationships and primary keys. The document concludes by explaining how to perform CRUD operations on models in an object-oriented way using Django's ORM APIs.
Introduction to Cross-platform App DevelopmentHoang Nguyen
Cross-platform mobile app development allows writing code once that can run on multiple operating systems and devices. It uses a virtual machine that compiles source code into bytecode that can run on different hardware platforms. Xamarin allows building native mobile apps for Android, iOS, and Windows using C# and .NET. Apps are compiled to native code for each platform, delivering native performance while sharing most of the development code cross-platform.
The document discusses consistency of random forests. It summarizes recent theoretical results showing that random forests are consistent estimators under certain conditions. Specifically, it is shown that random forests are consistent if the number of features sampled at each node (mtry) increases with sample size and the minimum node size decreases with sample size. The document also discusses how consistency holds even when the splitting criteria are randomized, as in random forests, as long as the base classifiers are consistent.

This document discusses the future of data storage and the rise of NoSQL databases. It notes that while SQL databases have dominated for decades, their suitability is cracking due to limitations in scaling and integration. NoSQL databases are designed to run on clusters across many machines, have flexible schemas, and are open source. They allow for embracing large scale and reducing development drag. However, relational databases are still relevant for some use cases. The future is one of "polyglot persistence" using the best data storage technology for each application's needs.

Are you interested in dipping your toes in the cloud native observability waters, but as an engineer you are not sure where to get started with tracing problems through your microservices and application landscapes on Kubernetes? Then this is the session for you, where we take you on your first steps in an active open-source project that offers a buffet of languages, challenges, and opportunities for getting started with telemetry data.
The project is called openTelemetry, but before diving into the specifics, we’ll start with de-mystifying key concepts and terms such as observability, telemetry, instrumentation, cardinality, percentile to lay a foundation. After understanding the nuts and bolts of observability and distributed traces, we’ll explore the openTelemetry community; its Special Interest Groups (SIGs), repositories, and how to become not only an end-user, but possibly a contributor.We will wrap up with an overview of the components in this project, such as the Collector, the OpenTelemetry protocol (OTLP), its APIs, and its SDKs.
Attendees will leave with an understanding of key observability concepts, become grounded in distributed tracing terminology, be aware of the components of openTelemetry, and know how to take their first steps to an open-source contribution!
Key Takeaways: Open source, vendor neutral instrumentation is an exciting new reality as the industry standardizes on openTelemetry for observability. OpenTelemetry is on a mission to enable effective observability by making high-quality, portable telemetry ubiquitous. The world of observability and monitoring today has a steep learning curve and in order to achieve ubiquity, the project would benefit from growing our contributor community.

Tester Training Course 2011
31. A code review is a special kind of inspection in
which the team examines a sample of code and
fixes any defects in it.
In a code review, a defect is a block of code which
does not properly implement its requirements,
which does not function as the programmer
intended, or which is not incorrect but could be
improved
• For example, it could be made more readable or its
performance could be improved
Tester Training Course 2011
32. It’s important to review the code which is most likely
to have defects. This will generally be the most
complex, tricky or involved code.
Good candidates for code review include:
• A portion of the software that only one person has the
expertise to maintain
• Code that implements a highly abstract or tricky algorithm
• An object, library or API that is particularly difficult to work
with
• Code written by someone who is inexperienced or has not
written that kind of code before, or written in an unfamiliar
language
• Code which employs a new programming technique
• An area of the code that will be especially catastrophic if
there are defects
Tester Training Course 2011
34. Pair programming is a technique in which two
programmers work simultaneously at a single
computer and continuously review each others’
work
Although many programmers were introduced to
pair programming as a part of Extreme
Programming, it is a practice that can be valuable
in any development environment.
Pair programming improves the organization by
ensuring that at least two programmers are able
to maintain any piece of the software
Tester Training Course 2011
35. In pair programming, two programmers sit at one
computer to write code. Generally, one programmer will
take control and write code, while the other watches and
advises
• Some teams have found that pair programming works best for
them if the pairs are constantly rotated; this helps diffuse the
shared knowledge throughout the organization. Others prefer to
pair a more junior person with a more senior for knowledge
sharing
The project manager should not try to force pair
programming on the team; it helps to introduce the
change slowly, and where it will meet the least resistance
• It is difficult to implement pair programming in an organization
where the programmers do not share the same nine-to-five (or
ten-to-six) work schedule.
• Some people do not work well in pairs, and some pairs do not
work well together
Tester Training Course 2011
36. Review is a static testing method(without running)
We have many types of review
From informal to formal
How to choose the appropriate level of formality
• The maturity of the development process
• Legal or regulatory requirements
Tester Training Course 2011
37. Manager
• decides on What is to be reviewed; schedule; closure
Moderator(review leader)
• planning the review, moderate review meeting and
follow up after meeting
Author
• takes responsibility for fixing any agreed defects
Reviewer
• identify and describes defects(with solutions)
Scriber(recorder)
• attends the review meeting and documents all of the
issues and defects, problems and open points
Tester Training Course 2011
43. Process issues
must follow the rules but keep it simple
make the process only as formal as the
project culture or maturity level allows
do not become too theoretical or
too detailed
checklist and roles are
recommended to increase
the effectiveness of
defect identification
Tester Training Course 2011
47. Question
What is the main difference between a
walkthrough and an inspection?
An inspection is lead by the author, whilst a
walkthrough is lead by a trained moderator
An inspection has a trained leader, whilst a
walkthrough is lead by a trained moderator
A walkthrough is lead by the author, whilst an
inspection is lead by trained moderator
Authors are not present during inspections, whilst
they are during walkthroughs
Tester Training Course 2011
48. Question
Which of the following statements about reviews
is true?
Reviews cannot be performed on user reuirements
specifications
Reviews are the least effective way of testing code
Reviews are unlikely to find faults in test plans
Reviews should be performed on specifications,

Tester Training Course 2011
52. Question
An important benefit of code inspections is that
they:
Are cheap to perform
Can be performed by the person who wrote the
code
Can be performed by inexperienced staff
Enable the code to be tested before the execution
enviroment is ready
Tester Training Course 2011
53. Question
Objective of design review meeting is
To identify problems with design
To solve the problems with design
Both A and B
None of the above
Tester Training Course 2011
54. Question
______reviews are often held with just the
programmer who wrote the code and one or two
other programmers or testers
Formal Reviews
Peer Reviews
Semi Formal Reviews
All of the above
Tester Training Course 2011
55. Question
Which of the following activities differentiate a
walkthrough from a formal review
A walkthrough does not follow a defined process
For a walkthrough individual preparation by the
reviewers is optional
A walkthrough requires meeting
A walkthrough finds the causes of failures, while
formal review finds the failures
Tester Training Course 2011
56. Question
What makes an inspection different from other
review types
It is led by a trained leader, uses formal entry and
exit criteria and checklists
It is led by the author of the document to be
inspected
It can only be used for reviewing design and code
It is led by the author, uses checklists, and collects
data for improvement
Tester Training Course 2011
58. A form of automated static testing
• exactly automated review
• check for violations of standards
• check for things which may be fault
often used by developer to automated code
review, and is called Static Code Analysis
also used by designer to review software
models, and is called Analysis of Models
Tester Training Course 2011
59. Does the program terminate?
How large can the heap become during
execution?
What is the possible output?
Some question about PC
• what is value of variable x when it is used
• Can the pointer p be null
• is the variable x initialized before it is read
• what is a lower and upper bound on the value of a
variable
• etc
Tester Training Course 2011
65. Static Code Analysis to the rescue
Tester Training Course 2011
66. Use an automatic systematic approach
Use formal methods and measures
Without running code => can be applied
earlier
Some kinds of defects are hard to find by
dynamic testing
Tester Training Course 2011
69. The most well-known feature of SCA
Define coding standard
• a set of programming rules
Often configured on IDE
Without such tools, more violations
• the number of rules is usually so large that nobody
can remember them all
• some context-sensitive rules that demand reviews
of several files are very hard to check by human being
• avoid checking coding standards in review, that will
distract them from other defects
Tester Training Course 2011
70. Is the study of data flow structure
Data flow structure follows the trail of
data items as it is accessed and modified
by the code
Typical defects can be found
• referencing a variable with an undefined value
• variables that are never used
Tester Training Course 2011
71. Data flow structure
• variable defined where a value is stored into it
• variable used where the stored value is accessed
• variable is undefined before it is defined or when it
goes out of scope
y = x+z;
//y is defined; x,z are used
if a>b then read(c);
//a,b are used; c is defined
Tester Training Course 2011
72. n := 0;
n is re-defined without
read (x); being used
n := 1; ==> Data flow anomaly
while x > y do
begin y is used before it has
read (y); been defined
==> Data flow fault
write( n*y);
x := x – n;
end;
Tester Training Course 2011
73. Data structure refers to the organization
of the data itself, independent of the
program
Provides a lot of information about the
difficulty in writing programs to handle the
data; then is used in designing test cases
Sometimes a program is complex
because it has a complex data structure,
rather than because of complex control or
data flow
Tester Training Course 2011
74. Is the study of control flow structure
Control flow structure addresses the
sequence in which the instructions are
executed
Typical defects can be found
• unreachable(dead) code
• infinite loops
• any jumps to undefined labels
• provide the code metrics
• whether code conforms to a flowchart grammar
Tester Training Course 2011
75. a := 4;
b := 15;
z := 7;
while b > z do
begin
writeln(z);
z++;
if(a>b) then
b:=a; unreachable(dead) code
end;
Tester Training Course 2011
76. Why
• How big and complex
• Help to decide among several design alternatives
• Help to decide how much risk
Typical code metrics
• LOC – Lines of code
• operands & operators(Halstead’s metrics)
• fan-in & fan-out
• nesting levels
• OO metrics: inheritance tree depth, coupling & cohesion
Tester Training Course 2011
77. Is a measure of the complexity of a flow
graph
• the code that the flow graph represents
the more complex the flow graph, the
greater the measure
it can most easily be calculated as:
• complexity = number of decisions + 1
Tester Training Course 2011
78. What is the cyclomatic complexity?
