Hi 👋

Yesterday, chatting with @JLHwung we figured out that the command: yarn jest <name-of-the-pckg> --watch wasn't mentioned in the documentation.

A tiny PR to add it ^^

Let me know if it's useful or not.

Since there are equivalent flags also for TEST_GREP and TEST_DEBUG, why don't we document all of them?

Just to mention that the command TEST_DEBUG=true make test and yarn node --inspect-brk node_modules/.bin/jest --runInBand doesn't work on my machine 🙈

TIL about TEST_DEBUG=true 😬

Apart from the nitpicks, I was thinking about a more tabular view of this commands, what's your point of view?

[tony-go]

Fix nitpicks and reshape a bit the documentation.

👀

Let me know.

Great🚀

LGTM with some nits.

Don't know if we want to align the language in h4 subtitles. e.g. We can simplify put "Lint" here?

[tony-go]

My idea was to add a bit of structure to all these lines. But we can rethink it. :)
