Taking Tests Beyond the Elixir Base
Let’s test our Mastery project and then take a look at some of the more widely used elixer testing techniques.
We'll cover the following...
Basic testing
To execute the most simple form of tests, we’ll enter the following command:
Executable
mix test
Output
Finished in 0.2 seconds
10 tests, 0 failures
The 10 tests, 0 failures indicates that all tests have successfully passed.
Advanced testing techniques
Testing is a broad and controversial topic. The Elixir community has so far shown pretty basic tastes as far as testing tools go. In this section, we’ll look at a couple of exciting places where Elixir programmers are using more cutting-edge techniques for testing a functional core.
Code coverage
The first technique, code coverage, is to understand what’s tested and what’s not. Elixir has built-in tools to help us do so.
The mix tool allows coverage tracking. We suggest that having a coverage threshold as a metric for our ...
