You can try unity framework, wherein you can have test assertions on failure.
For example:
If you intend to test strcpy_s and you know that return value is EOK on success then any scenario of buffer overflow should make this test fail. Using TEST_ASSERT_EQUAL which takes first parameter as expected and second as actual, you can get appropriate test assertions.
TEST( C11AnnexK, strcpy_s_ReturnsEOKWhenCopyIsSuccess)
{
int retVal; // To catch return Value
char src[] = "strcpy_s Test";
char dest [5]; // Purposely dest is choosen smaller than src to demonstrate assertion
retVal = strcpy_s (destLargerThanSrc, sizeof(destLargerThanSrc, src);
TEST_ASSERT_EQUAL( EOK, retVal); // This should fail as retVal would differ (retVal will be ESNOSPC in this scenario)
// This will result in assertion claiming that this test failed
}

There are many such C test frameworks.
I'll rather use the current one. It's already fixed.
