Run only ONE test with Jest

Question

Very simple, I want to run just one test with Jest.

I put it.only or describe.only but it still runs a whole lot of tests. I think it runs

Answer 1

For me it works if I use 2 params like this:

yarn test --watch -f "src/...fullpath.../reducer.spec.js" -t "Name of the test"

Flags:

--watch: is optional

-f: will do filtering of your files, so if you have a lot of tests with the same name, specify the full path to the exact file

-t: works with 'describe' name or 'it' name of your test
