Testing a control unit by means of a test environment

A system arrangement for testing a control unit via a test environment, the arrangement comprising:

• a test management device configured for model-based development and management of at least one test plan implemented as a data structure in order to test the control unit, each test plan having at least one test and a start condition for initiating execution of the test plan;
• a test execution control device operating the test environment, wherein the test execution control device initiates execution of the at least one test plan on the test environment if the start condition is met;
• and
• a database device configured to store the data structure of the at least one test plan and connected, for shared, common, simultaneous, real-time access to the test plan, to the test management device and the test execution control device,
• wherein the test management device, the test execution control device, and the database device are separate and connected to each other,
• wherein the test management device and the test execution control device each have direct access to the database device, the test management device providing the test plan to the database device based on the control unit under test.
