-    For linking python tests to requirements **metadata** shall be used. Attributes which are
-    common for all test cases can be specified in the Test Suite (above the class), the other
-    attributes which are specific for each test case need to be specified above the test case:
+    For linking python tests to requirements **metadata** shall be used. 
+    For this the 'add_test_properties' decorator has been provided. 
+    You need to add it to the test and fill out:
+    
+    * partially_verifies OR fully_verifies 
+    * test_type 
+    * derivation_technique
+
+    For allowed values for test_type & derivation_technique please check :need:`gd_req__verification_link_tests`
+    Further more, this decorator will also check if your test has a `docstring` which should act as the description of the test.
