Hi Suho, I have added the test cases to all the cases you have mentioned except the four listed below because having more than two pattern operands is not supported by Siddhi. I hope it is okay to skip those test cases. WDYT?
- every ( (not C and D) and B ) -> A - every ((not C and D) or B ) -> A - every (B and (not C and D) ) -> A - every (B or (not C and D) ) -> A If there are no more cases to test, may I start with the SEQUENCE?
