◆ UT_EXPECT_ASSERT_FAILURE

#define UT_EXPECT_ASSERT_FAILURE	(	FunctionCall,
		Status
	)	FunctionCall;

This macro uses the framework assertion logic to check whether a function call triggers an ASSERT() condition. The BaseLib SetJump()/LongJump() services are used to establish a safe return point when an ASSERT() is triggered. If an ASSERT() is triggered, unit test execution continues and Status is set to UNIT_TEST_PASSED. Otherwise, a unit test case failure is raised and Status is set to UNIT_TEST_ERROR_TEST_FAILED.

If ASSERT() macros are disabled, then the test case is skipped and a warning message is added to the unit test log. Status is set to UNIT_TEST_SKIPPED.

Parameters

A test case should pass any needed context (which, to prevent an infinite loop, should be at least the current execution count) which will be saved by the framework and passed to the test case upon resume.

This should be called while the current test framework is valid and active. It is generally called from within a test case prior to quitting or rebooting.

Parameters

[in]	ContextToSave	A buffer of test case-specific data to be saved along with framework state. Will be passed as "Context" to the test case upon resume. This is an optional parameter that may be NULL.
[in]	ContextToSaveSize	Size of the ContextToSave buffer.

◆ UnitTestExpectAssertFailure()

BOOLEAN EFIAPI UnitTestExpectAssertFailure	(	IN UNIT_TEST_STATUS	UnitTestStatus,
		IN CONST CHAR8 *	FunctionName,
		IN UINTN	LineNumber,
		IN CONST CHAR8 *	FileName,
		IN CONST CHAR8 *	FunctionCall,
		OUT UNIT_TEST_STATUS *ResultStatus	OPTIONAL
	)

If UnitTestStatus is UNIT_TEST_PASSED, then log an info message and return TRUE because an ASSERT() was expected when FunctionCall was executed and an ASSERT() was triggered. If UnitTestStatus is UNIT_TEST_SKIPPED, then log a warning message and return TRUE because ASSERT() macros are disabled. If UnitTestStatus is UNIT_TEST_ERROR_TEST_FAILED, then log an error message and return FALSE because an ASSERT() was expected when FunctionCall was executed, but no ASSERT() conditions were triggered. The log messages contain FunctionName, LineNumber, and FileName strings to provide the location of the UT_EXPECT_ASSERT_FAILURE() macro.

Parameters

[in]	UnitTestStatus	The status from UT_EXPECT_ASSERT_FAILURE() that is either pass, skipped, or failed.
[in]	FunctionName	Null-terminated ASCII string of the function executing the UT_EXPECT_ASSERT_FAILURE() macro.
[in]	LineNumber	The source file line number of the the function executing the UT_EXPECT_ASSERT_FAILURE() macro.
[in]	FileName	Null-terminated ASCII string of the filename executing the UT_EXPECT_ASSERT_FAILURE() macro.
[in]	FunctionCall	Null-terminated ASCII string of the function call executed by the UT_EXPECT_ASSERT_FAILURE() macro.
[out]	ResultStatus	Used to return the UnitTestStatus value to the caller of UT_EXPECT_ASSERT_FAILURE(). This is optional parameter that may be NULL.

Return values

TRUE	UnitTestStatus is UNIT_TEST_PASSED.
TRUE	UnitTestStatus is UNIT_TEST_SKIPPED.
FALSE	UnitTestStatus is UNIT_TEST_ERROR_TEST_FAILED.
