Write tests that don't slow you down

Phoenix LiveView brings a new set of testing tools and requires a new way of thinking about our tests.

Don't write tests that

only the original author understands
fail intermittently, costing you hundreds of hours of development time
run so slow you check Twitter every time you run them

Instead, master LiveView's new testing tools, learn the thought process behind what, when, and how to test LiveView, and rediscover the joy of having tests that are

fast 🏎
robust 💪, and
easy to maintain 🛠
