Ruby's Got You Covered

Perhaps you've heard of test coverage, which is a measurement of how much of your application code is executed when your tests run. That number is typically represented as a percentage, and people may use that metric to assess the relative health of a codebase. The efficacy of such metrics is debated, but the metrics are still prevalent.This article will demonstrate the mechanism ruby provides to measure coverage and present some examples for how to use it and is a summary of the information I shared about coverage at RubyConf 2020.
