JavaScript Simplified Course: https://javascriptsimplified.com/?utm_source=youtube&utm_medium=video-description&utm_term=video-id-Zs2IpqHzchw 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. 📚 Materials/References: JavaScript Simplified Course: https://javascriptsimplified.com/?utm_source=youtube&utm_medium=video-description&utm_term=video-id-Zs2IpqHzchw Code Coverage Article: https://www.epicweb.dev/making-use-of-code-coverage 🌎 Find Me Here: My Blog: https://blog.webdevsimplified.com My Courses: https://courses.webdevsimplified.com Patreon: https://www.patreon.com/WebDevSimplified Twitter: https://twitter.com/DevSimplified Discord: https://discord.gg/7StTjnR GitHub: https://github.com/WebDevSimplified CodePen: https://codepen.io/WebDevSimplified ⏱️ Timestamps: 00:00 - Introduction 01:18 - Problem #1 04:45 - Problem #2 09:30 - Problem #3 #CodeCoverage #WDS #JavaScript
