CPPTEST_ASSERT_ENUM_EQUAL(scoped_enum_name, expected, actual)

Asserts that two integral values are equal. If it fails both the actual and expected values are reported as enumerators. If the integral value does not map to enumerator identifier from specified enum then test case error is reported. See Handling Enum Values for details.

CPPTEST_ASSERT_ENUM_EQUAL_MESSAGE(scoped_enum_name, msg, expected, actual)

Asserts that two integral values are equal, like CPPTEST_ASSERT_ENUM_EQUAL described above, and in addition, provides a custom message on failure. See Handling Enum Values for details.

The program receives three parameters (param1, param2, param3). If it returns a non-zero value, the assert fails and the program stdout is used as the failure message.
CPPTEST_ASSERT_EXTERNAL_MESSAGE(message, program, param1, param2, param3)Uses an external application to validate values. The first parameter specifies the executable to run. The program receives three parameters (param1, param2, param3). If it returns a non-zero value, the assert fails and the custom message is used as the failure message.
CPPTEST_ASSERT_MEMORY_LEAKS()

Asserts that dynamic memory blocks allocated during the current test case execution were deallocated before this macro call.

Note: This macro requires the Memory Monitoring feature to be enabled in the Test Configuration (see Runtime Error Detection).

CPPTEST_ASSERT_EQUAL_FMT(expected, actual, format)

Asserts that two values are equal. Reports assertion with expected / actual values in a custom format.

These assertions use the C-standard snprintf() function to convert expected / actual values to their string representation using the custom pattern (<format> string).

Additional notes:

  • The C-standard snprintf() function needs to be available for C++test's Test Harness.
  • The format string (<format>) should be compliant with the C-standard printf() function.
  • <expected>, <actual> and <delta> values need to be specified according to their real types, in a format accepted / expected by the printf() function - e.g. when the format for floating point values string is "%f", valid float values should be specified (for example, 0.0, not 0).
  • There is a buffer size defined for the resulting value string. If the actual value string size exceeds the buffer size, an execution error will be reported.
  • The default size of the output buffer is set to 24 bytes. The size of the buffer can be customized by adding the following option to Project Properties> C++test> Build Settings> Compiler Options: -DCPPTEST_FMT_BUFFER_SIZE=<new buffer size in bytes>.
