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

it's like this:

jest sometest.test.js -t "some expression to match a describe or a test"

it will test all files with the name sometest.test.js and matching based on -t option, if you only want to test a specific file you can do this:

jest src/user/.../sometest.test.js
