    1. How to test at the correct level?
    2. As many things in life, deciding what to test at each level of testing is a trade-off:
    3. Unit tests are usually cheap, and you should consider them like the basement of your house
    4. A system test is often better than an integration test that is stubbing a lot of internals.
    5. Only test the happy path, but make sure to add a test case for any regression that couldn’t have been caught at lower levels with better tests (for example, if a regression is found, regression tests should be added at the lowest level possible).
    6. Black-box tests at the system level (aka end-to-end or QA tests)
