The document discusses various types of software testing including manual testing, automation testing, black box testing, white box testing, grey box testing, functional testing (unit, integration, system, acceptance, and regression testing), and non-functional testing (performance, security, usability, and portability testing). Testing documentation and the testing process are also summarized including test plans, test scenarios, test cases, when to start and stop testing, and references.

Introduction
- is the process of evaluating a system or its component(s) with the
intent to find that whether it satisfies the specified requirements or
not.
- is executing a system in order to identify any gaps, errors or missing
requirements in contrary to the actual desire or requirements.

Testing Types
Manual
Testing
Automation
Testing

6. 6
- This type includes the testing of the
Software manually i.e. without using any
automated tool or any script.
Manual Testing

7. 7
- Automation testing is when the tester writes scripts and uses
another software to test the software.
Automation Testing
- Examples:
- Visual Studio.
- IBM Test.

Methods of Testing
Black Box Grey BoxWhite Box

9. 9
Black Box Testing
- Testing without having any knowledge of the interior workings
of the application.
- Called blind testing or closed box system .
- The tester does not have access to the source code.

10. 10
Advantages Disadvantages
- efficient for large code
segments.
- Code Access not required.
- Large numbers of normal
skilled testers can test the
application.
- Inefficient testing.
Black Box Testing (cont..)

11. 11
White Box Testing
-Detailed investigation of internal logic and structure of the code.
- Called glass testing or open box testing
-The tester needs to possess knowledge of the internal working of
the code.

12. 12
White Box Testing (cont..)
Advantages Disadvantages
- It helps in optimizing the code.
- Maximum coverage is attained
during test scenario writing.
- The costs are increased.

13. 13
Grey Box Testing
- Limited knowledge of the internal workings of an application.
- Called limited knowledge testing.
- The tester has access to design documents and the database

14. 14
Grey Box Testing (cont..)
Advantages Disadvantages
- Grey box testers don't rely on
the source code.
- a grey box tester can design
excellent test scenarios.
- The test is done from the
point of view of the user and
not the designer
- Test coverage is limited.

Integration Testing
Regression Testing
System Testing
Acceptance Testing

17. 17
Unit Testing
- Unit testing is performed by the respective developers on the
individual units of source code assigned areas.
Unit

18. 18
Integration Method is testing combined parts of an application
to determine if they function correctly together.
- There are two methods :
Integration Testing
Unit Unit Unit
- Bottom-up Integration testing.
- Top Down Integration testing.

19. 19
System Testing
- System Testing tests the system as a whole.
- Once all the components are integrated, the application as a
whole is tested rigorously to see that it meets Quality Standards.

20. 20
Regression Testing
- The intent of Regression testing is to ensure that a change,
such as a bug fix did not result in another fault being uncovered in the
application.

21. 21
Acceptance Testing
- By performing Acceptance test on an application the testing
team will deduce how the application will perform in production.
- Consists of:
- Alpha Testing.
- Beta Testing.

22. 22
Acceptance Testing (cont..)
ALPHA TESTING
- Unit testing, integration testing and system testing when
combined are known as alpha testing.
BETA TESTING
- In beta testing a sample of the intended audience tests the
application

Non-Functional Testing
Performance
Portability
Security
Usability

24. 24
Performance Testing
- It is mostly used to identify any bottlenecks or performance
issues rather than finding the bugs in software
- Performance testing is considered as one of the important
and mandatory testing types in terms of following aspects:
- Speed
- Capacity
- Stability
- Scalability

25. 25
Performance Testing (cont..)
Load testing
- Determine Maximum load:
- Users
- Data
- Specify Normal and peak load conditions.
Stress testing
- Testing of Software behavior under abnormal conditions.
- Examples:
- Database On-Off.
- Server Down.

26. 26
- Usability testing is for user-friendliness.
- Will depend on the targeted end-user or customer.
- Make User interviews, surveys, video recording of user sessions.
Usability Testing

27. 27
- Security Testing is the testing of Software in order to identify
any gaps from security.
Security Testing

28. 28
Portability Testing is the testing of Software with intend that it
should be re-useable and can be moved from another Software as
well.

Test Plan
Test plan outlines:
-The strategy that will be used to test an application
-The resources that will be used
-The test environment in which testing will be performed
-The schedule of testing activities.

31. 31
Test Case
The main intent of this activity is to ensure whether the Software
Passes or Fails in terms of its functionality and other aspects.
Case Actual Expected

32. 32
Test Scenario
- Test Scenarios are used to
ensure that all process flows are
tested from end to end.
Test Case 1
Test Case 2
Test Case 3

Test Case 1
Test Case 2
Test Case 3
Scenario 2

33. 33
When to Start Testing?
- An early start to testing reduces the cost, time to rework.
- Water fall model formal testing is conducted in the Testing
phase.
- Incremental model, testing is performed at the end of every
increment and at the end the whole application is tested.

34. 34
When to Stop Testing?
- Testing Deadlines.
- Completion of test case execution.
- Management decision.
