@vue/cli-plugin-unit-jest test configuration broken

[umbertooo]

Version

3.0.0-rc.3

Reproduction link

https://github.com/umbertooo/vue-cli-with-jest-plugin

Steps to reproduce

1. create project vue create vue-jest-demo, for brevity I post the stored preset:

"vue-with-jest": {
    "useConfigFiles": true,
    "plugins": {
    "@vue/cli-plugin-babel": {},
    "@vue/cli-plugin-eslint": {
        "config": "base",
        "lintOn": [
        "save"
        ]
    },
    "@vue/cli-plugin-unit-jest": {}
    }
}

2. cd vue-jest-demo
3. npm run test:unit

What is expected?

I expect the example test tests/unit/HelloWorld.spec.js to be run.

What is actually happening?

> [email protected] test:unit /Users/myuserhome/vue-jest-demo
> vue-cli-service test:unit

No tests found
