UNITY: Unit Testing for C

This module is a fork of the UNITY test framework with minor modifications to be able to use it with the utest harness for Mbed OS.

Please note that this module only contains the unity test macros, and no additions such as the unity fixtures. Furthermore the failure macros have been modified to integrate with utest failure handlers, as setjmp and longjmp are not supported by utest.

Specifically

• UNITY_FAIL_AND_BAIL calls utest_unity_assert_failure(), and
• UNITY_IGNORE_AND_BAIL calls utest_unity_ignore_failure()

which then invoke the appropriate action in utest.

To use these macros you need to depend on both unity and utest!

Macros

UNITY provides a lot of test macros.

Be aware of the macro argument order: (EXPECTED VALUE, ACTUAL VALUE).
So TEST_ASSERT_EQUAL(4, value); is the right way around.

Note, that you can provide a custom failure message by appending _MESSAGE to any macro and passing the message string as the last argument.
