A test infrastructure consisting of a test system (including all systems for performing tests), test data, and test tools is used to perform the tests. The test infrastructure is provided according to the test concept. The test infrastructure must meet different requirements depending on the test method. Different test systems may then also be required.

The test infrastructure is based on the infrastructure of the production system, i.e. on the operating infrastructure realized. The test system must correspond to the production system to the extent that the test case descriptions can be carried out under realistic conditions.

If non-anonymized copies of productive data are used as test data for the tests, the requirements for ISDP must be met.
