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)

For a different perspective, here’s a DreamForce session that I absolutely agree with.
