Per System Tests

[EvanLF6768]

Currently GTest is only run on the common directory. This should be expanded to run tests on each of the systems as well.

Unit Tests

Operate the same way as the existing common unit tests. Device/OS specific code should not be included when compiling for tests. There should be a target to run the unit tests on each system as well as a target to test everything.

Baremetal Integration Tests

An alternate main function should run through various device functions an assert that the state of the system is valid, failing assertions should signal back to the host system and optionally trigger a breakpoint. There should be a target which will deploy and run such a test.

Checkpoints

• All targets exist (but currently no-ops)
• Subsystem unit tests
• Baremetal test assertion functions
• Conditional compilation/deployment of test_main function
• Host system communication of test status
• Optional breakpoint on assertion failure
