3. Outro

3.1. Cons/critcism

3.1.1. Test hooks can become out of date

3.1.1.1. Requires maintainence just like prod code

3.1.2. Not testing end user flows

3.1.2.1. Show the pyramid slide

3.1.2.2. Don't use them exclusively, have some pure E2E tests as well

3.2. Benefits

3.2.1. KISS

3.2.1.1. Keep test code simple

3.2.1.1.1. Exercise only part of the app that is relevant to the test. Mock other pieces

3.2.1.2. Creating tests is easy, maintaining them over hundreds of runs over a period of years is hard

3.2.2. DRY

3.2.2.1. Don't repeat same actions in all tests

3.2.3. Makes parallel runs of tests more manageable

3.3. Achieve
