TEST_FAIL	For advanced cases, fail unconditionally but don't return (so a test can return multiple results)
TEST_ASSERT	Asserts that a condition is true If the condition is not true, fails the test
TEST_ASSERT_NOTNULL	Asserts that a parameter is not null
TEST_ASSERT_NULL	Asserts that a parameter is null
TEST_ASSERT_EQUAL	Asserts that the two parameters passed are equal, fails otherwise Optionally allows an additional message in the case of a failure
TEST_ASSERT_NOTEQUAL	Asserts that the two parameters passed are not equal, fails otherwise Optionally allows an additional message in the case of a failure
TEST_FOCUS	Only run the test provided within the parentheses This is useful for debugging when you want to reduce noise, but should never be pushed Intended to be used in the manner of `TEST_FOCUS(/datum/unit_test/math)`
TEST_NOTICE	Logs a noticable message on GitHub, but will not mark as an error. Use this when something shouldn't happen and is of note, but shouldn't block CI. Does not mark the test as failed.
UNIT_TEST_PASSED	Constants indicating unit test completion status
TEST_LONGER	After most test steps, used for tests that run long so shorter issues can be noticed faster
TEST_CREATE_AND_DESTROY	This must be the one of last tests to run due to the inherent nature of the test iterating every single tangible atom in the game and qdeleting all of them (while taking long sleeps to make sure the garbage collector fires properly) taking a large amount of time.
TEST_AFTER_CREATE_AND_DESTROY	For tests that rely on create and destroy having iterated through every (tangible) atom so they don't have to do something similar. Keep in mind tho that create and destroy will absolutely break the test platform, anything that relies on its shape cannot come after it.
TEST_OUTPUT_RED	Change color to red on ANSI terminal output, if enabled with -DANSICOLORS.
TEST_OUTPUT_GREEN	Change color to green on ANSI terminal output, if enabled with -DANSICOLORS.
TEST_OUTPUT_YELLOW	Change color to yellow on ANSI terminal output, if enabled with -DANSICOLORS.
TRAIT_SOURCE_UNIT_TESTS	A trait source when adding traits through unit tests
