Upsides: Easy to read errors and understand how to fix them. It's also very helpful for reviewing PRs as it can direct you to parts of the codebase that probably need the most work. Review collected by and hosted on G2.com.
Downsides: Tests can be slow to run, I find myself staring at the screen for minutes at a time, waiting for the results to load which slows down my development time significantly. Review collected by and hosted on G2.com.
