A test case describes the object to be tested. Manual and automatic test cases are distinguished. You can create and edit test cases in the Computer Aided Test Tool CATT.

A test catalog is a set of test cases in a hierarchical hypertext structure. This structure can be augmented by links to supplementary documents. To be able to use the test catalog to generate test plans, you must put it in the SAP Application hierarchy. 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 test cases, which must be tested, in a particular period for a particular purpose. The relevant test cases can be divided among 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 in a specified period.

After a test, the tester sets the test case status, e.g. ‚Pass‘ or ‚Fail‘. You can get an overview of the status of all test cases of a test plan with Status analyses.
