Please go install this extension.

This extension makes working with Jest magical ✨

Some highlights:

  • Every time you save a file your test suite will run so you can failures faster. (this is configurable if your tests take a long time to run.)
  • A nice little visual indicator on the tests themselves that they past their last run.
  • The ability to debug individual tests.
  • Inline you can see test failures. You can see which test is failing and why.
  • A nice test explore pane on the sidebar.
  • You can update Jest snapshots directly from a prompt in VS Code.
  • You can see Jest snapshots directly from the test code without having to navigate to them.

I'm a big fan. Now every time I work with Jest I use it. Highly suggest installing it anytime you're near Jest.
