• Key Concepts: 
  A test class is a type of ABAP class used to test the functionality of other ABAP classes. It is used to check the correctness of the code and to ensure that the program behaves as expected. It is part of the BC-ABA ABAP Runtime Environment. 
  
  How to use it: 
  Test classes are used to test the functionality of other ABAP classes. They are written in a way that allows them to be reused for different tests. To create a test class, you need to define a method that will be used to execute the tests. This method should contain all the necessary code for running the tests. Once the method is defined, you can then call it from other classes or programs. 
  
  Tips & Tricks: 
  When writing a test class, it is important to make sure that all tests are independent from each other. This means that each test should be able to run without relying on any other tests. Additionally, it is important to make sure that all tests are repeatable and reliable. This means that they should always produce the same results when run multiple times.
