What is test double in SAP BC-ABA - ABAP Runtime Environment?

SAP Term: test double

• Component: BC-ABA

• Component Name: ABAP Runtime Environment

• Description: Simulates a component required for the execution of a module test also called "DOC", or depended-on component, but which cannot be used by the test for technical or organizational reasons. For example, the component may cause unwanted changes to be made in the system, the component may need to be configured, or it may require persistent data. A test double simulates the interface and the behavior of the "depended-on component" in the scope required for the module test to run. In an ABAP module test, methods are used to construct [class_]setup a test double as a part of the fixture of the module test, and deconstruct it [class_]teardown.

• Key Concepts: 
  Test double is a term used in software testing to refer to a type of object that mimics the behavior of a real object in controlled ways. It is used to replace the real object in order to test the functionality of the system without having to use the real object. In SAP, test doubles are used in the BC-ABA ABAP Runtime Environment. 
  
  How to Use It: 
  Test doubles are used in the BC-ABA ABAP Runtime Environment to simulate the behavior of a real object. This allows for testing of the system without having to use the real object. The test double can be configured to behave in certain ways, such as returning specific values or throwing exceptions, which can be used to test different scenarios. 
  
  Tips & Tricks: 
  When using test doubles, it is important to ensure that they are configured correctly and that they behave as expected. This can be done by running tests with the test double and verifying that it behaves as expected. Additionally, it is important to ensure that the test double is not used in production code, as this could lead to unexpected results. 
  
  Related Information: 
  Test doubles are related to other software testing techniques such as stubs and mocks. Stubs are objects that are used to replace real objects in order to simulate their behavior, while mocks are objects that are used to verify that certain methods have been called or certain conditions have been met. Additionally, test doubles can be used in conjunction with other software testing techniques such as unit testing and integration testing.
