**Grey box testing** is a software testing technique that combines aspects of both black box and white box testing. It involves testing the software with partial knowledge of the internal workings of the application. This means the tester has limited access to the internal structures or algorithms, usually at the level of data structures and algorithms but not at the level of the source code itself.

32
-**Balanced Approach**: It offers a balanced approach by combining the methodologies of black box and white box testing, allowing testers to design test cases based on the functional specifications and internal behavior of the system.
33
33
-**Improved Test Coverage**: By understanding the internal structures, testers can create more effective test cases that cover a wider range of possible inputs and states, potentially finding defects that are missed by black box testing.
34
34
-**Enhanced Security Testing**: It can help identify security vulnerabilities that are not visible from the outside (black box) but do not require full code access (white box).
35
35
-**Efficient Defect Identification**: It helps in identifying defects that might be related to data flow and control flow within the system.

### 3. Pattern Testing
52
52
53
53
Pattern testing identifies and tests common patterns of use, error, or failure within the application. By having some knowledge of the internal architecture, testers can focus on areas where patterns are most likely to emerge.

### 4. Orthogonal Array Testing
