Grey box testing is a software testing technique that combines elements of both white box and black box testing. In grey box testing, the tester has partial knowledge of the internal workings of the software under test. This partial knowledge allows the tester to design test cases that target specific areas of the code while still focusing on testing the overall functionality and behavior of the system.

1. WHITE BOX TESTING
2. BLACK BOX TESTING
3. GREY BOX TESTING

2. WHITE BOX TESTING
• White box testing, also known as glass box testing, clear box
testing, or structural testing,
• It is a software testing technique where the internal structure,
design, and implementation of the software under test are
examined.
• In white box testing, testers have access to the source code
and are able to design test cases based on the internal logic of
the application.

3. Key aspects of white box testing include:
• Understanding of Internal Logic
• Code Coverage
• Test Case Design
• Knowledge of
• Programming Languages
• Unit Testing
• Integration Testing

4. Benefits:
White box testing can uncover hidden errors, ensure
comprehensive test coverage, and help improve the quality and
reliability of the software.
Challenges:
White box testing requires detailed knowledge of the
internal implementation, which may not always be feasible or
practical. Additionally, changes to the code may necessitate
updates to the test cases, making maintenance challenging.

5. Black box testing
• Black box testing is a software testing technique where the
internal structure, design, and implementation of the software
under test are not known to the tester.
• Instead, the tester interacts with the software as an end-user
would, focusing on testing the functionality and behavior of the
system without knowledge of its internal workings.

6. Key aspects of black box testing include:
• Independence from Internal Implementation
• Test Case Design
• Functional Testing
• Boundary Value Analysis
• User-Centric Perspective
• Regression Testing

7. Benefits:
Black box testing provides an unbiased assessment of
the software's functionality, regardless of its internal
implementation. It helps uncover defects and ensures that the
software meets the specified requirements and user
expectations.
Challenges:
Black box testing may not uncover certain types of
defects related to the internal logic or implementation of the
software. Additionally, designing comprehensive test cases
without knowledge of the internal structure can be challenging.

8. GREY BOX TESTING
• Grey box testing in software security involves assessing the
security of a system with partial knowledge of its internal
workings.
• This approach combines elements of both white box and black
box testing techniques to identify vulnerabilities and
weaknesses in the software from a security standpoint.
