The document discusses various software testing strategies and concepts. It covers the goals of testing as verification (building the software right) and validation (building the right software). It also discusses different types of testing such as black box testing (based on inputs and outputs) and white box testing (based on code). Other topics covered include levels of testing (unit, integration, system), test measures, and a software testing plan.
This is the most important topic of OOAD named as Object Oriented Testing. It is used to prepare a good software which has no bug in it and it performs very fast. <a href="https://harisjamil.pro">Haris Jamil</a>

Anand Bagmar - Behavior Driven Testing (BDT) in AgileAnand Bagmar
I delivered this talk in SiliconIndia's SoftTec 2012 on 14th July 2012. I introduce Behavior Driven Testing (BDT) with a couple of examples, the different ways of writing the tests in Imperative and Declarative style, the value proposition of BDT, and how BDT can help you build a very good safety net using Test Automation suite.
In software testing, there are many paths between the entry and exit of a software program. So it’s difficult to fully test all paths of even a simple unit. This is a challenge when we design test cases.
As more and more companies are moving to the Cloud, they want their latest, greatest software features to be available to their users as quickly as they are built. However there are several issues blocking them from moving ahead.
One key issue is the massive amount of time it takes for someone to certify that the new feature is indeed working as expected and also to assure that the rest of the features will continuing to work. In spite of this long waiting cycle, we still cannot assure that our software will not have any issues. In fact, many times our assumptions about the user's needs or behavior might itself be wrong. But this long testing cycle only helps us validate that our assumptions works as assumed.
How can we break out of this rut & get thin slices of our features in front of our users to validate our assumptions early?
Most software organizations today suffer from what I call, the "Inverted Testing Pyramid" problem. They spend maximum time and effort manually checking software. Some invest in automation, but mostly building slow, complex, fragile end-to-end GUI test. Very little effort is spent on building a solid foundation of unit & acceptance tests.
This over-investment in end-to-end tests is a slippery slope. Once you start on this path, you end up investing even more time & effort on testing which gives you diminishing returns.
In this session Naresh Jain will explain the key misconceptions that has lead to the inverted testing pyramid approach being massively adopted, main drawbacks of this approach and how to turn your organization around to get the right testing pyramid.

Chapter 10 Testing and Quality Assurance1Unders.docxketurahhazelhurst
Chapter 10:
Testing and Quality
Assurance
1
Understand quality & basic techniques for software verification and validation.
Analyze basics of software testing and testing techniques.
Discuss the concept of “inspection” process.
Objectives
2
Quality assurance (QA): activities designed
to measure and improve quality in a product— and process.
Quality control (QC): activities designed to validate and verify the quality of the product through detecting faults and “fixing” the defects.
Need good techniques, process, tools,
and team.
Testing Introduction
similar
3
Two traditional definitions:
Conforms to requirements.
Fit to use.
Verification: checking software conforms to
its requirements (did the software evolve
from the requirements properly; does the software “work”?)
Is the system correct?
Validation: checking software meets user requirements (fit to use)
Are we building the correct system?
What Is “Quality”?
4
Testing: executing program in a controlled environment and “verifying/validating” output.
Inspections and reviews.
Formal methods (proving software correct).
Static analysis detects “error-prone conditions.”
Some “Error-Detection” Techniques (finding errors)
5
Error: a mistake made by a programmer or software engineer that caused the fault, which in turn may cause a failure
Fault (defect, bug): condition that may cause a failure in the system
Failure (problem): inability of system to perform a function according to its spec due to some fault
Fault or failure/problem severity (based on consequences)
Fault or failure/problem priority (based on importance of developing a fix, which is in turn based
on severity)
Faults and Failures
6
Activity performed for:
Evaluating product quality
Improving products by identifying defects and having them fixed prior to software release
Dynamic (running-program) verification of program’s behavior on a finite set of test cases selected from execution domain.
Testing can NOT prove product works 100%—even though we use testing to demonstrate that parts of the software works.
Testing

Who tests?
Programmers
Testers/Req. Analyst
Users
What is tested?
Unit code testing
Functional code testing
Integration/system testing
User interface testing
Testing (cont.)
Why test?
Acceptance (customer)
Conformance (std, laws, etc.)
Configuration (user vs. dev.)
Performance, stress, security, etc.
How (test cases designed)?
Intuition
Specification based (black box)
Code based (white box)
Existing cases (regression)

Progression of Testing
Equivalence Class Partitioning
Divide the input into several groups, deemed “equivalent” for purposes of finding errors.
Pick one “representative” for each class used for testing.
Equivalence classes determined by req./design specifications and some intuition
Example: pick “larger” of
two integers and . . .
Lessen duplication.

What is Software Testing Software Testing is an activity in software development.
It is an investigation performed against a software to provide information about the quality of the software to stakeholders.
Software testing is associated with the two terms.
Validation: Are we doing the right job?
Verification: Are we doing the job right?

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
2. Software Testing
Testing is the process of exercising a program with the
specific intent of finding errors prior to delivery
o the end user.
errors
requirements conformance
performance
an indication
of quality
2
3. Who Tests the Software?
developer
Understands the system
but, will test "gently"
and, is driven by "delivery "
3
independent tester
Must learn about the system,
but, will attempt to break it
and, is driven by quality
5. Goals
Verification: Have we built the software right?
Bug-free, meets specs
Validation: Have we built the right software?
Meets customers’ needs
Are Verification and Validation different or variation of the
same idea
My argument: “meeting specs” should equal “meeting
customer needs”...
not generally true (my kitchen, satellite systems)
6. Software Testing
Goals
Types of tests
Levels of tests
Test measures
Test plan
most of this discussion focuses
on verification
(more specifically bug testing)
8. Black box tests
input
output
interfa
ce
1. Does it perform the specified
functions?
2.Does it handle obvious errors in
input?
3.Ariane5 – lousy error handling
4.Classic ints vs floats, yards vs
meters
Black box should catch these if
there is adequate “test coverage”
10. Black box tests
Advantage: black box tester≠developer is unbiased by
implementation details. e.g., Use Case testing, just work through
all the Use Cases
Disadvantage: black box tester is uninformed about
implementation details
unnecessary tests – test same thing in different way
insufficient tests – can miss the extremes, especially if actual use
follows a different pattern
12. unnecessary tests
Input
Code
large range of input may exercise a small part of code
e.g., operator test of satellite control stations, run through
each
input and output light/key option. Testing same functions,
13. insufficient tests
Input
Code
a small range of input may exercise a large range of code
but can you ‘know’ this without knowing the code? Did we miss
the 20%
16. Example: ordered list of ints
class ordInts {
public: …
private:
int vals[1000];
int maxElements=1000;
…
}
17. Example: ordered list of ints
bool testMax()
{
L=create();
num=maxElements;
for (int i=0; i<=num; i++)
print i
L.insert(i)
print maxElements;
}
18. White box tests
Advantage:
design tests to achieve good code coverage and avoid duplication
can stress complicated, error-prone code
can stress boundary values (fault injection)
Disadvantage:
tester=developer may have bias
if code changes, tests may have to be redesigned (is this bad?)
19. Example: ordered list of ints
L=create()
L.insert(1)
L.insert(2)
L.insert(3)
class OrdInts
create
getFirst
1
2
3
insert
delete
print
…
L.insert(1001)
p=L.getFirst()
print(p)
p=L.getNext(p)
print p
…
…
getNext
20. Types of tests
Black box: test based on interface, through interface
White box: test based on code, through code
Testing strategy can/should include all
approaches!
My experience:
Black Box = non developer, outside testing idiots
in your case who?
White Box = developer, part of development process
in your case who?
Gray Box = hated, non developer within developer
organization
in your case who?

22. White-Box Testing
Basis Path
Testingwe compute the cyclomatic
First,
complexity:
number of simple decisions + 1
or
number of enclosed areas + 1
In this case, V(G) = 4
22
23. White-Box Testing
Basis Path
Next, we derive the
Testing independent paths:
1
Since V(G) = 4,
there are four paths
2

Path 1:
Path 2:
Path 3:
Path 4:
1,2,4,7,8
1,2,3,5,7,8
1,2,3,6,7,8
1,2,4,7,2,4,...7,8
Finally, we derive test
cases to exercise these
paths.
A number of industry studies have indicated
that the higher V(G), the higher the probability
23
or errors.
26. Black-Box Testing
Comparison Testing
Used only in situations in which the reliability of software is
absolutely critical (e.g., human-rated systems)
Separate software engineering teams develop independent
versions of an application using the same specification
Each version can be tested with the same test data to ensure
that all provide identical output
Then all versions are executed in parallel with real-time
comparison of results to ensure consistency
26
28. Testing measures (white box)
Code coverage – individual modules
Path coverage – sequence diagrams
Code coverage based on complexity – test of the risks, tricky
part of code (e.g., Unix “you are not expected to understand
this” code)
29. Levels of Testing
Unit testing
Integration testing
Validation testing
Focus is on software requirements
System testing
Focus is on system integration
Alpha/Beta testing
Focus is on customer usage
Recovery testing
forces the software to fail in a variety of ways and verifies that recovery is properly performed
Security testing
verifies that protection mechanisms built into a system will, in fact, protect it from improper penetration
Stress testing
executes a system in a manner that demands resources in abnormal quantity, frequency, or volume
Performance Testing
test the run-time performance of software within the context of an integrated system
29
30. Unit Testing
Tests the smallest individually executable code units.
Usually done by programmers. Test cases might be
selected based on code, specification, intuition, etc.
Tools:
Test driver/harness
Code coverage analyzer
Automatic test case generator
31. Integration Testing
Tests interactions between two or more units or
components. Usually done by programmers.
Emphasizes interfaces.
Issues:
In what order are units combined?
How do you assure the compatibility and correctness of
externally-supplied components?
32. Integration Testing
How are units integrated? What are the implications of
this order?
Top-down => need stubs; top-level tested repeatedly.
Bottom-up => need drivers; bottom-levels tested repeatedly.
Critical units first => stubs & drivers needed; critical units tested
repeatedly.
34. Stages of Testing
Testing in the Large
System Testing
End-to-End Testing
Operations Readiness Testing
Beta Testing
Load Testing
Stress Testing
Performance Testing
Reliability Testing
Regression Testing
35. System Testing
Test the functionality of the entire system.
Usually done by professional testers.
36. Realities of System Testing
Not all problems will be found no matter how thorough or
systematic the testing.
Testing resources (staff, time, tools, labs) are limited.
Specifications are frequently unclear/ambiguous and changing
(and not necessarily complete and up-to-date).
Systems are almost always too large to permit test cases to be
selected based on code characteristics.
