Jest comes pre-packaged with the ability to track code coverage for the modules you're testing, but it takes a little extra work to make it track untested files as well. Let's look at what Jest can do for you, what you have to do yourself, and how to…

How much of your code runs during unit testing is an extremely valuable metric to track. Utilizing code the karma-coverage plugin and babel-plugin-__coverage__ plugin, we can get an accurate measure of how well we’re covering the files that we are te…
