Jest: [Feature Request] - Run a specific test from the command line

[damonbauer]

I'd love the ability to append a line number to a test in the CLI and have Jest run only that test. Similar to fit or fdescribe, but not having to edit the test file.

RSpec has the functionality I'm describing: https://relishapp.com/rspec/rspec-core/v/3-5/docs/command-line/line-number-appended-to-file-path

It's smart enough to pick up a test close to where you specify (it doesn't have to be the first line of the test). For instance, if an it block takes up lines 75-81, and you append :80, the CLI runs just that test.

Yes this will be in the next release as testNamePattern or -t.

Is it possible to specify a line number? I see that as soooo useful in the context of an editor, being able to run whatever test is under your cursor (similar to the rspec approach above).
