Gray box testing is a combination of white-box and black-box testing techniques. It involves partial knowledge of the internal structure of an application. Gray box testers generate test cases based on requirements and functional specifications rather than source code. Some advantages are that it benefits from both black-box and white-box testing while remaining non-intrusive. Disadvantages include only partial code coverage due to limited internal access. Gray box testing is suitable for web applications and functional/business domain testing.

4. Gray-box Testers
Black-box tester is unaware if internal
structure of the system.
White-box tester is know internal structure of
the system.
Gray-box tester partially knows the internal
structure & algorithms of defining test cases.
Need overall and detailed description of
documents of the application.

5. What we need for Gray-box
Testing
Gray-box testing is applies straight
forward technique of black-box testing
and influences it against the code targeted
systems in white-box testing.
Gray-box testing is based on requirement
test case generation because it presets all
the condition before program is tested by
using assertion method.

6. Gray-box Testing
Techniques
 Matrix Testing
-States the status report of the project
 Regression Testing
-Rerunning of the test cases if new changes are
made.
 Pattern Testing
-Rerunning of the test cases if new changes are
made.
 Orthogonal Array Testing
-Used as subset of all possible combination.

7. Advantages of Gray-box
Testing
 Offers combined benefits: It serves advantages
from both Black-box and White-box Testing.
 Non Intrusive: Based on functional specification,
architectural view whereas not on source code or
binaries which makes it invasive too.
 Intelligent Test Authoring: Tester handles
intelligent test scenario. Ex: data type handling,
communication protocol, exception handling.
 Unbiased Testing: Gray-box testing maintains
boundary for testing between tester and developer.

8. Disadvantages of Gray-box
Testing
Partial code coverage: Source code or
binaries are missing because of limited
access to internal or structure of the
applications which results in limited access
for code path traversal.
Defect Identification: In distributed
applications, it is difficult to associate
defect identification.

9. Suitable Applications
Web Applications: The Web
Applications have distributed network or
systems.
Functional or business domain
testing: Functional testing is done
basically a test of user interactions with
may be external systems.
