3. What is software testing?
• Software testing is a method of assessing the
functionality of a software program.

4. Why we need software
testing?
1. To deliver the best application we can.
2.To test compatibility.

5. Why we need software
testing?
3. To make sure that your website is always up and running.
4.To ensure that what we create does what it’s supposed to do.

6. Software testing lifecycle(STLC)

7. Software testing lifecycle(STLC)
• Requirements/design review:
In case of confusion

8. Software testing lifecycle(STLC)
• Test planning:
In this phase the QA manager prepare the Test
Plan and Test strategy documents.

9. • Test Case Development:
Software testing lifecycle(STLC)
Verification of Creation of

10. • Environment Setup:
This phase includes the setup or installation process of software and
hardware which is required for testing the application.
Software testing lifecycle(STLC)

11. • Test Execution:
In Test Execution phase the test cases are executed in the
testing environment.

12. • Test Cycle Closure:
In Test Cycle phase the QA team will meet and discuss
about the testing artifacts.

13. Types of software testing
Acceptance testing
Load testing
Stress testing
Performance testing
Usability testing
Install/uninstall testing
Recovery testing
Security testing
Compatibility testing
Comparison testing
Alpha testing
Beta testing
System testing
Integration testing
Acceptance testing

14. Software testing levels

15. Unit Testing
• Unit testing is a method by which individual units of
source code are tested to determine if they are fit for
use.

16. Unit Testing

17. • Types of testing:
Unit Testing

18. • Unit testing is supported by frameworks which are available
in different programming languages( JUnit , Google test
framework).
• The main elements of a unit framework:
 Test case.
 Test suite.
 Test fixture.
 Test result.
Unit Testing

19. Integration testing
• Integration testing is executed to establish whether the
components interact with each other consort to the
specification or not.
• Types of Integration Testing:
1)Top-Down Integration Testing
2) Bottom-Up Integration Testing

20. System testing
• System testing is the type of testing to check the
behavior of a complete and fully integrated software
product based on the software requirements
specification (SRS) document.

21. Acceptance testing
• Acceptance testing: Formal testing with respect to user
needs, requirements, and business processes
conducted to determine whether or not a system
satisfies the acceptance criteria and to enable the user,
customers or other authorized entity to determine
whether or not to accept the system.(Definition by
ISTQB)
• It is basically done by the user or customer .

22. Regression Testing
• What is Regression Testing?
It is a test that is made after any modification or update
occurs to the software to ensure that the existing
functionality is intact or not and that system update does
not re-introduce errors.

23. Regression Testing
Given program P, its modified version P’, and a test set T
that was used to previously test P, find a way to utilize T
to gain sufficient confidence in the correctness of P’

24. Regression testing is used when:
• Any new feature is added
• Any enhancement is done
• Any bug is fixed
• Any performance related issue is fixed
Regression Testing

25. • Regression Techniques:
Regression Testing

26. • Regression process:
Regression Testing

28. Software testing in the Cloud
• Cloud testing is migrating testing to the cloud in which
reduce the execution time for regression testing.
• Benefits:
1. virtualized hardware.
2. Unlimited storage.
3. Software services that help in reducing the execution
time.

29. Cloud testing & the supported types:
Software testing in the Cloud

30. • SMART-T:
The decision of whether or not to migrate software testing
to the cloud depending on three issues:
• the business drivers outlined
• the technical factors
• the operational results
Software testing in the Cloud

31. SMART-T

32. Software testing in the Cloud
• Hadoop: is a framework free and open source written in Java to facilitate
the creation of applications distributed and scalable for applications to work
with thousands of nodes and petabytes of data.
• The cloud enables organizations to deploy
Hadoop without acquiring hardware or
expertise.
• Vendors with a cloud offer include:
Microsoft, Amazon, IBM 9 and Google.
