White box testing or unit testing: To do white box testing, knowledge of internal logic code is required. It is mostly done by developers.

Black box testing: The functionality of an application is tested; logic code is not required. This testing is done by testers.

Block box or system testing: Testing the application without knowledge of underline code of the application. it is done by the testers.

Dynamic white-box testing, in a nutshell, is using information you gain from seeing what the code does and how it works to determine what to test, what not to test, and how to approach the testing. Another name commonly used for dynamic white-box testing is structural testing because you can see and use the underlying structure of the code to design and run your tests.
