Explanation:
White box testing is the process of testing an application when you have detailed knowledge of the inner
workings of the application.
White-box testing (also known as clear box testing, glass box testing, transparent box testing, and structural
testing) is a method of testing software that tests internal structures or workings of an application, as opposed
to its functionality (i.e. black-box testing). In white-box testing an internal perspective of the system, as well as
programming skills, are used to design test cases. The tester chooses inputs to exercise paths through the
code and determine the appropriate outputs. This is analogous to testing nodes in a circuit, e.g. in-circuit testing
(ICT).
White-box testing can be applied at the unit, integration and system levels of the software testing process.
Although traditional testers tended to think of white-box testing as being done at the unit level, it is used for
integration and system testing more frequently today. It can test paths within a unit, paths between units during
integration, and between subsystems during a system–level test.
