This talk is dedicated to all frontend developers willing to write Vitest/jest tests not being flaky or failing unexpectedly with any code change delivered. We go through several most common mistakes and dive a little bit deeper into battle tested patterns helping to write stable, valuable and maintainable tests scenarios. We discuss things like what is the most optimal level testing for components, what integration really means for them as well as what we should mock effectively.
You’ll be surprised how many mistakes you’ve been making so far, usually turning test maintenance into a never ending nightmare. And you’ll get even more surprised realising how straight forward it really can be.
