TP Behaviour Initial conditions (optional) The initial conditions define in which initial state the IUT has to be to apply the actual TP. In t

22、he corresponding “Test Case“ (TC), when the execution of the initial condition does not succeed, it leads to the assignment of an Inconclusive verdict. Expected behaviour (TP body) Definition of the events, which are parts of the TP objective, and the IUT are expected to perform in order to conform

23、to the base specification. In the corresponding TC,“ Pass“ or “Fail“ verdicts can be assigned there.
