HI @AthiraHari77
Many thanks for the PR.
I'm only slightly concerned about this assertion.
The logic here is that

  1. decisions could be decisionsId or decisionName (IINW)
  2. if an error message contains one of them, then the decisions it relates to is "wrong"

I'm afraid there could be some cases where an error message contains the decisionId or decisionName, but that the error is not in the decision itself (e.g. another element that refer that decision)

.filter(messages -> decisions.length == 0 || Arrays.stream(decisions).anyMatch(messages::contains)).collect(Collectors.toList());
if (!identifiedErrors.isEmpty()) {
throw new IllegalStateException(String.join(", ", identifiedErrors));
}
}

public boolean performRuntimeTypeCheck(DMNModel model) {
Objects.requireNonNull(model, () -> MsgUtil.createMessage(Msg.PARAM_CANNOT_BE_NULL, "model"));
return overrideRuntimeTypeCheck || ((DMNModelImpl) model).isRuntimeTypeCheck();

I would go for the more readable assertThatIllegalStateExceptionIsThrownBy(.... Consider this also in the other tests.
