Lee's 10 Rules of Apex

I’ve seen a couple versions of rules developers feel are core to good Apex code.

I’d like to throw these into the ring as concepts that have been helpful to me, and that I deviate from at my own peril:

1. Write your tests FIRST

2. NO hard coded values

3. Use a test data factory

4. Test for predictability, not coverage

5. If it doesn’t assert, it’s not a test

6. Use a custom error class

7. Don’t repeat yourself

8. JS > VF

9. Don’t repeat yourself

10. Standard is better than custom (use everything you pay for)
