-1. Place breakpoints or `debugger` statements in the test or the underlying code wherever you'd like `jest` to pause.
-2. Open the file containing the test in question, and make sure its tab is active (so you can see the file's contents).
-3. Switch to the debugger in the sidebar and choose `Debug unit tests - just open file` from the dropdown.
-4. Click the green "play" button to run the tests in the open file in watch mode.
-
-Pro tip: If any of your breakpoints are in code run by multiple tests, and you run the whole test file, you'll land on
-those breakpoints over and over again, in the middle of tests you don't care about. To avoid this, replace the test's
-initial `it` or `test` with `it.only` or `test.only`. That way, when you hit a breakpoint, you'll know you got there are
