What are Testing methods and Testing Techniques?
And what is difference between them?
Techniques is a term most commonly used to represent the Test (Case) Design Techniques. The most familiar ones are equivalence partitions, boundary value analysis, state-transition etc.
Test methods isn't so common a term in the testing literature or in general use. However, in an object-oriented environment (e.g. Java) programmer-testers probably would use such a term to describe methods in code to test their Classes.
