behaviour of `test:unit --watch` changed?

Version

3.0.0-beta.11

Reproduction link

https://github.com/doppelreim/vue-test-app/tree/test-watch-behaviour

Steps to reproduce

Install dependencies: npm install

Run the unit-tests in “watch-mode”: ./node_modules/.bin/vue-cli-service test:unit --watch

After they have passed, open “Other.spec.ts” and change something. For example, change the expectation from 8 to 7.

Save the file.

The tests are run again, automatically (because of --watch)

What is expected?

At least in beta6, only the tests contained in the file that changed are run again.

What is actually happening?

In beta12, all tests are run again.

I’m not sure, what the actually intended behaviour is. Maybe it should always have been like this. But it is different 😃

I just added "test:unit:watch": "vue-cli-service test:unit --watch" to the scripts section in my package.json, works like a charm.

Old issue, but maybe some lone googler can use this: For me running npm run test:unit -- --watch works as expected on a newly instantiated project.

See https://docs.npmjs.com/cli/run-script

npm will pass all the arguments after the – directly to your script:
