A test catalog is a set of test cases in a Hypertext structure. This structure can contain links to additional documents. To be able to use the test catalog to generate test plans, you must put it in the SAP Application hierarchy. The test catalog is assigned in the SAP environment. You can create test plans across several test catalogs via the SAP application hierarchy. This procedure allows you to create a lot of small test catalogs, which are easier to maintain than one large test catalog.

A test plan is a set of tests which must be performed within a specified period for a specified purpose. The test cases can be in several test catalogs.

A test package is a person and period-oriented view of a test plan. It contains all tests which a tester is to perform during a specified period.

A test case describes the object to be tested. Test case attributes determine the test case types. Test cases are created and performed in the CATT: Computer Aided Test Tool.

A test case is given a test case status with reference to the structure nodes of a test package, as the result of a test. The test is analyzed by a status report which can create various views (e.g. of particular test packages).
