3. What is Gray Box Testing?
“Gray Box Testing is a combination
of White-box Testing and Black-box
Testing.”
-Wikipedia

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.
