What is the gray box test?
Gray box testing is a software testing methodology that combines white box and black box testing. It uses the simple technique of black box testing and the code-oriented system approach, as in the case of white box testing. Testers using gray box tests need extensive application documentation to complete the tests. The gray box test is designed to find defects that are based on an unsuitable structure or application.
Gray box tests are also known as translucent tests.
Because gray box testers have access to design documentation skills, they can prepare and create better test cases and plans. However, the test approach offers testers only limited knowledge of various application functionalities.
The advantages of gray box tests are:
- Works well for large segments of code.
- Testers do not need to know any programming language or methods to test the application, which makes these tests largely unbiased and non-intrusive.
- Access to the programming code is not required.
- Provides clearly defined roles for users and developers during testing. Testing is based on the perspective of the user rather than that of the designer.
Disadvantages of the gray box tests are:
- Most test cases are difficult to design.
- As there are only a few test scenarios, the coverage is limited.
- Since testers have limited knowledge of the process, this is not considered an efficient testing method.
