100% Code Coverage Is Useless

JavaScript Simplified Course: https://javascriptsimplified.com/?utm...

Many companies use some form of test coverage metric to measure how well tested their code is. Oftentimes these metrics are set as rules that must be maintained at all times. This is a terrible idea, though. Test coverage in general is a poor metric that doesn’t actually tell you anything meaningful about your code or the confidence you should have in it being bug free. In this video I talk about why test coverage is a bad metric and what you should do instead.
