I feel like this is a stupid question, but I can't find the answer anywhere.

Is there a way to run a single test file for a single Lightning Web Component.

I essentially want to be able to pass a filename when I run npm run test:unit so that only one test runs at a time instead of all my tests.

I have test:unit mapped to a script in my package.json file. Here is a snippet:

"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "test:unit": "lwc-jest --verbose",
    "test:unit:log": "lwc-jest"
}

You can just pass e. g. a file name after your script name

E. g:

npm run test:unit mycomponent.test.js

Would all tests matching a file named mycomponent.test.js

    I could have sworn I had tried that already and it didn't work. Oh well. Thanks for the quick and simple answer. – aaron Jun 17 at 16:39
