What is Testing Methodology?

Test methodology is the technical way about how to test a software. Typically, people refer to black-box and white-box for methodologies.

Black-box Testing is mainly testing at system-level, as customers may use the software. Often, it is pretty-much same as system-test. It is the most-common way of testing a product/software when it has end-users; but it may not be applicable when the software is not intended for end-uses, like API.

White-box testing is mainly testing the software as th testers know the detailed logics/codes about the software. It test the internal logics, conditions, operations of the code. It is typically used for unit/functional testing and also for software that has no end-users (like APIs).
