Since two patterns are used for checking events, it can't be setup by default at startup causing every test that wants to check events to have to set up the data buffer (using either pattern A or B):

Pattern A uses UT_CF_ResetEventCapture, UT_CF_CheckEventID_Impl, UT_CF_CapturedEventIDs, example:

CF/unit-test/cf_app_tests.c

Lines 299 to 306 in 557c132

	UT_CF_ResetEventCapture(UT_KEY(CFE_EVS_SendEvent));
	/* Act */
	UtAssert_INT32_EQ(CF_TableInit(), result);
	/* Assert */
	UtAssert_STUB_COUNT(CFE_EVS_SendEvent, 1);
	UT_CF_AssertEventID(CF_EID_ERR_INIT_TBL_REG);

Pattern B set's up a custom buffer:

CF/unit-test/cf_app_tests.c

Lines 637 to 664 in 557c132

	uint16 events[2] = {0};
	memset(&sbbuf, 0, sizeof(sbbuf));
	/* Run loop once */
	UT_SetDeferredRetcode(UT_KEY(CFE_ES_RunLoop), 1, true);
	UT_SetDefaultReturnValue(UT_KEY(CFE_ES_RunLoop), false);
	/* Capture events */
	UT_SetDataBuffer(UT_KEY(CFE_EVS_SendEvent), events, sizeof(events), false);
	/* Unit under test does not use the buffer in this case */
	UT_SetDataBuffer(UT_KEY(CFE_SB_ReceiveBuffer), &sbbufptr, sizeof(sbbufptr), false);
	UT_SetDeferredRetcode(UT_KEY(CFE_SB_ReceiveBuffer), 1, -1);
	/* Act */
	UtAssert_VOIDCALL(CF_AppMain());
	/* Assert */
	UtAssert_STUB_COUNT(CFE_ES_PerfLogAdd, 4);
	UtAssert_STUB_COUNT(CFE_ES_RunLoop, 2);
	UtAssert_STUB_COUNT(CFE_ES_ExitApp, 1);
	/* Event from CF_Init and CF_AppMain */
	UtAssert_STUB_COUNT(CFE_EVS_SendEvent, 2);
	UtAssert_UINT32_EQ(events[0], CF_EID_INF_INIT);
	UtAssert_UINT32_EQ(events[1], CF_EID_ERR_INIT_MSG_RECV);

Describe the solution you'd like
