This video covers:
0:15 - Context blocks
4:07 - RSpec let
6:16 - described_class
7:17 - subject
7:59 - Simplifying tests with subject and 1-line expectations
In this video I'll cover how to use context blocks, within RSpec describe blocks, to test different cases. I'll cover RSpec's let feature and explain how to use it to simplify your tests. Lastly I'll cover RSpec's `described_class` and `subject` methods and explain how to use them with a real world example.
