PHPUnit is a representative of unit testing frameworks, whose overall idea is to provide a strict contract over an isolated piece of code that must be satisfied. This piece of code is what we call unit, which translates to the class and its methods in PHP. Using the assertions functionality, the PHPUnit framework verifies that these units behave as expected. The benefit of unit testing is that its early problem detection helps mitigate compound or down-the-line errors that might not be obvious initially. The more possible paths of a program the unit test covers, the better.
