Assumes test-runner is installed and you are in the project folder.

Place a debugger statement in your test:

tom.test('Example', async () => {
  debugger
})

Run test-runner using Node.js directly with the --inspect-brk flag set:
```
$ node --inspect-brk node_modules/.bin/test-runner
```
Open Google Chrome and navigate to chrome://inspect/.
In the "Remote Target" section, click "Inspect" on the test-runner target.
In DevTools, click "run" to start test-runner. Execution will pause at the debugger statement.
