- The classes can be used in the context of ABAP Unit to create test doubles in a standardized way.
- The test doubles replace dependent-on components (DOC) during unit tests.
- DOCs:
- Classes and interfaces:
- `CL_ABAP_TESTDOUBLE`: ABAP OO Test Double Framework
- Database (e.g. database tables or CDS view entities)
- `CL_OSQL_TEST_ENVIRONMENT`: ABAP SQL Test Double Framework; to test ABAP SQL statements that depend on data sources such as database tables or CDS view entities
- `CL_CDS_TEST_ENVIRONMENT`: ABAP CDS Test Double Framework; to test logic implemented in CDS entities
- RAP business objects
- `CL_BOTD_TXBUFDBL_BO_TEST_ENV`: Creating transactional buffer test doubles
- `CL_BOTD_MOCKEMLAPI_BO_TEST_ENV`: Mocking ABAP EML APIs
- Note that more classes are available for other use cases.
- For more information, see the [ABAP Unit Tests](14_ABAP_Unit_Tests.md) cheat sheet and the [documentation](https://help.sap.com/docs/abap-cloud/abap-development-tools-user-guide/managing-dependencies-with-abap-unit).
