Code Coverage Metrics with SimpleCov

By August 30, 2013

Follow me on:

Code coverage metrics are an important, but often ignored, part of test-driven development. Code coverage tools like SimpleCov give you an overview of how many lines of code your tests cover, and which lines are and are not covered. Code coverage is not a perfect tool though, SimpleCov won't tell you how good your tests are or what they actually tested for, but they'll at least tell you there is code that isn't covered by any tests, which is the very minimum a good test suite should do.
