I have many test suites. I wanna to run a singe one and skip all the others, and I would like to do this on the code level.

I know I can do this using .only() and .skip() in a test file, but that supports only the tests / describes defined in that file.

Is there a way to do this globally? Like is there something like .only() which - when called on the top level describe - runs only that test suite and all others are skipped? Or: when called on a single test ( it().only() ), then only that test runs and nothing else?

I see nothing like this in the API, but maybe Jest can be configured to work this way?

Is this possible with Jest or is this something I can only do via CLI?

CodePudding user response：

If I understand correctly: You want to run just one test suite/file.

You can do this from the command line with jest path/to/filename.test.js.

Within a file, you can use test.only(name, fn, timeout) to only run that test. This won't stop Jest from moving on to the next testing file though.

As far as I am aware, you cannot do this from within the test file itself.
The closest I can think of would be to set the `testmatch' in Jest's config to a pattern that only matches the file(s) you want run.

package.json

{
  "name": "my-project",
  "jest": {
    "testmatch": "**/my.test.js"
  }
}
