Add yarn debug-test to debug tests in Chrome

[gaearon]

Works just like yarn test and can also run with a watcher or for a particular file.

yarn debug-test
yarn debug-test IncrementalErrorHandling
yarn debug-test --watch IncrementalErrorHandling

To debug, open chrome://inspect, select the target and then press Play.

You can set breakpoints too, both in individual source files and in the test itself.

Pretty neat!

Wow. Today I learned. I thought this wasn't possible because of an issue with the VM module. Awesome!

👍 very cool! QQ - is there any way to get source maps to view the original source code when doing this? Thanks!

[gaearon]

Don’t know about the sourcemaps.

Don’t know about the sourcemaps.

Is there any way to debug the code with sourcemap in vscode? Thanks!
