My problem was because my tests was in a tests directory instead of test/jest/__tests__/ directory

Now tests are executing fine

Test Suites: 2 passed, 2 total
Tests:       10 passed, 10 total
Snapshots:   0 total
Time:        8.011s
Ran all test suites.

I also tried with a globally install quasar-cli (ie without npx) using

$ npm install -g @quasar/cli

But I’m facing same problem

$ quasar run @quasar/testing test --unit jest
 app:extension Running "@quasar/testing" Quasar App Extension... +0ms
 app:run Running "@quasar/testing" > "test" command +10ms

You tried to run tests with jest, but it is not installed. Please install @quasar/quasar-app-extension-unit-jest with quasar ext --add @quasar/testing-unit-jest

I still don’t understand how to run my jest unit tests using Quasar.

Hello,

I’m trying to install quasar/testing for setting unit testing with a Quasar app.

$ npx quasar run @quasar/testing test --unit jest
 app:extension Running "@quasar/testing" Quasar App Extension... +0ms
 app:run Running "@quasar/testing" > "test" command +3ms

You tried to run tests with jest, but it is not installed. Please install @quasar/quasar-app-extension-unit-jest with quasar ext --add @quasar/testing-unit-jest

$ npx quasar ext --add @quasar/testing-unit-jest
 app:extension-manager Listing installed App Extensions +0ms

Extension name: @quasar/testing
Extension prompts: {
  "harnesses": [
    "unit-jest"
  ]
}

$ npx quasar run @quasar/testing test --unit jest
 app:extension Running "@quasar/testing" Quasar App Extension... +0ms
 app:run Running "@quasar/testing" > "test" command +5ms

You tried to run tests with jest, but it is not installed. Please install @quasar/quasar-app-extension-unit-jest with quasar ext --add @quasar/testing-unit-jest

I don’t understand why quasar/quasar-app-extension-unit-jest is not installed correctly.

Any idea?

Kind regards
