The exact scope of a “unit” is often left to interpretation, but a nice rule of thumb is to define a unit as the least amount of code needed to perform a standalone task, for example, a single method or class. The purpose of unit testing is to examine the individual components or pieces of methods/classes to verify functionality, ensuring the behavior is as expected. The tester chooses inputs to exercise particular paths through the code and configures assertions that validate the output. Unit testing is a form of white box testing in which test cases are based on internal structure. Let’s first talk a little bit about what unit testing is and why it matters in general.
