A modern truck contains a large amount of functionality implemented in its electronic systems. These functions can be all from changing channel on the radio, avoid uncontrolled acceleration of the truck due to a broken hardware component or to make the driver aware of a fault that causes the exhaust emissions to be higher than allowed by the legal requirements.
To be confident that the system fulfils its requirements, the system is tested by automated test scripts in a Hardware In the Loop simulator (HIL).
To gain speed in the development process, the most important faults in the systems needs to be found as early as possible.Target
Define a method that based on different risk factors optimizes the order to test the requirements (test suite). In the case of an abort event; the test cases that did not run will be less critical than the test cases that were able to finish before the abort event.
A test suite with tests A, B and C are to be run. A runs first resulting in a passed result, but during execution of test case B the environment crashes and the tests are halted. Since the test suite was ordered with the most critical test case first we know that the result of test case A was more critical than the unfinished B and C.Assignment
