FB_TestCaseBase
FB_TestCaseBase is the base function block for new test cases. This function block already includes a wide range of methods related to test case management. This applies, for example, to the method FB_init, in which the function block automatically registers with the test controller. You do not need to–and should not–override this method when implementing a new test case. In addition, methods are available for, among other things, comparing the results or advancing the test state machine. These are described below. The base test case also has the following internal variables:
