##RSpec Code Coverage Lab

How do we know we have enough tests, and that our tests cover all of our code?

Enter simplecov! simplecov is a tool that will measure your test run against the code paths in your code files and see if you're exercising them all. "Code Paths" includes method calls, conditional statements, loops, and anything that branches program flow.

This is important because you want to be able to know that every decision your program makes is being tested, no matter what.
