The invention relates to a computer-implemented method for adjusting a
test case (TC1) for a
security check of a
functional system to be tested of a mobile application, in particular from the automotive and / or aeronautical field, by means of a test
system, as well as to the test
system and to a related
computer program product. In this case, test cases (TC1) are provided to the test
system, which test cases have been used in the mobile application or for a
functional system used for the mobile application and / or can be used for such a
security check. The following steps are carried out: dividing the
test case (TC1) into test modules (T11,..., T14) (101); an abstract test module (T11,..., T14), in which system-specific information, data and parameters of the
functional system, which are contained in the test module (T11,..., T14) and to which the respective
test case (TC1) is applied, are replaced (102) by abstract placeholder variables in the respective test module (T11,..., T14); creating abstract test scenarios (TS1, TS2, TS3) for a
security check of the functional system to be tested, the abstract test modules (a1,..., a5) being combined (103) for a test
scenario (TS1, TS2, TS3); deriving (104) test cases (TC21, TC22, TC23) for the functional system to be tested from the abstract test scenarios (TS1, TS2, TS3), wherein respective abstract placeholder variables in the abstract test modules (a1,..., a5) of the respective test scenarios (TS1, TS2, TS3) are occupied with corresponding system-specific information, data and parameters of the functional system to be tested; and-applying the test cases (TC21, TC22, TC23) derived from the test scenarios (TS1, TS2, TS3) to the functional system (105) to be tested.
