Test names like "basic" are mentioned seven times in the code (ignoring case): Twice when defining the input and result macros, thrice when defining the test function, and twice again when calling it. Reduce that to a single time by using compound literals to pass the input and result arrays via TEST_INPUT to test_prio_queue().
