There are two types of tests for tuberculosis (TB) infection: the TB blood test and the TB skin test. A positive test result for TB infection means you have TB germs in your body. If you test positive for TB infection, your health care provider will do other tests to determine if you have inactive TB (also called latent TB infection) or active TB disease.
The TEST_P macro is followed by a set of parameters that are passed to the test case. In summary, TEST is for standalone test cases, TEST_F is for test cases with fixtures, and TEST_P is for test cases with parameters. The choice of which macro to use depends on the specific testing needs and requirements of your project.
