Your pluginsFile is set to /test/cypress/plugins/index.js, but either the file is missing, it contains a syntax error, or threw an error when required.

What did you get as the error?

I got this in the Cypress UI:

**Message:** The plugins file is missing or invalid.

Your `pluginsFile` is set to `/home/michael/dramawithfriends/www/test/cypress/plugins/index.js`, but either the file is missing, it contains a syntax error, or threw an error when required. The `pluginsFile` must be a `.js`, `.ts`, or `.coffee` file.

Or you might have renamed the extension of your `pluginsFile`. If that's the case, restart the test runner.

Please fix this, or set `pluginsFile` to `false` if a plugins file is not necessary for your project.

**Details:** /home/michael/dramawithfriends/www/test/cypress/plugins/index.js:21
export default pluginConfig;

The file is there, and says SyntaxError: Unexpected token ‘export’:

What were you expecting?

Tests to run.

What steps did you take, to get the error?

EDIT: This wasn’t clear.

1. Installed the testing harness $ quasar ext add @quasar/testing
2. ran quasar test:e2e
3. got the error above
4. Added babel: yarn add @babel/core @babel/cli
5. Tried again with this error:

This dependency was not found:

* /home/michael/dramawithfriends/www/.quasar/client-entry.js in multi (webpack)-dev-server/client?http://0.0.0.0:8080 (webpack)/hot/dev-server.js ./.quasar/client-entry.js

To install it, you can run: npm install --save /home/michael/dramawithfriends/www/.quasar/client-entry.js

Fixed in https://github.com/quasarframework/quasar-testing/commit/eb14b2de0cff5bbcb5144990cfa3d5d40b1bbe80 v2.0.4 released with the fix

Seems like that’s the only file not transpiled, and a community PR some times ago wrongly used ES5 import/export syntax. I reverted to the normal Node syntax and now it should work

[MichaelJCole]

rm yarn.lock
rm -rf .quasar
rm -rf node_modules
yarn
yarn run test:e2e

Brings me back to the original error.
