* MQE-1173: [Dev experience] Error on test generation without reference on file - Added error messaging at Action level - Extended range of errors caught at Test level - Added unit tests for Exception catching for TestGenerator and ActionMergeUtil * MQE-1173: [Dev experience] Error on test generation without reference on file - Removed unused use cases * MQE-1173: [Dev experience] Error on test generation without reference on file - Removed use * MQE-1173: [Dev experience] Error on test generation without reference on file - Added setting parameter list to [] in case of no parameters * MQE-1173: [Dev experience] Error on test generation without reference on file - Moved count out of matching method * MQE-1173: [Dev experience] Error on test generation without reference on file - Made requested changes - Updated unit tests to be a bit more descriptive
