Unit Test — Unit testing framework (PHPUnit)

Overview:

PHPUnit is a testing framework designed for programmers. It's part of the xUnit architecture for unit testing frameworks, which started with SUnit and grew in popularity with JUnit. Sebastian Bergmann designed PHPUnit, and its development is maintained on GitHub. This is a fantastic testing framework for developing PHP web application unit tests. We can direct test-driven enhancement with the aid of PHPUnit.

Fixtures:

Building the code to put the world up in a known state and then restore it to its original state when the test is over is one of the most time-consuming portions of writing tests. The fixture of the test refers to this known condition. The fixture for testing array operations with PHPUnit was the array saved in the $count variable. The fixture will almost always be more sophisticated than a basic array, and the amount of code required to set it up will increase proportionately. The noise of setting up the fixtures drowns out the real content of the exam. When you create numerous tests with comparable fixtures, the situation becomes even worse. We would have to replicate the code that sets up the fixture for each test we write if the testing framework didn't assist us out.
