e2e-cypress plugin for vue-cli
npm install @vue/cli-plugin-e2e-cypress> e2e-cypress plugin for vue-cli
This adds E2E testing support using Cypress.
Cypress offers a rich interactive interface for running E2E tests in Firefox and Chromium based browsers (Chrome, MS Edge, Brave, Electron). To learn more about cross browser testing, visit the Cypress Cross Browser Testing Guide.
> Note: If you have a hard requirement on E2E testing in IE or Safari, consider using the Selenium-based @vue/cli-plugin-e2e-nightwatch.
- vue-cli-service test:e2e
Run e2e tests with cypress run.
By default it launches Cypress in interactive mode with a GUI (via cypress open). If you want to run the tests in headless mode (e.g. for CI), you can do so with the --headless option.
The command automatically starts a server in production mode to run the e2e tests against. If you want to run the tests multiple times without having to restart the server every time, you can start the server with vue-cli-service serve --mode production in one terminal, and then run e2e tests against that server using the --url option.
Options:
``
--headless run in headless mode without GUI
--mode specify the mode the dev server should run in. (default: production)
--url run e2e tests against given url instead of auto-starting dev server
-s, --spec (headless only) runs a specific spec file. defaults to "all"
Additionally:
- In GUI mode, all Cypress CLI options for cypress open are also supported;
- In --headless mode, all Cypress CLI options for cypress run are also supported.
Examples :
- Run Cypress in headless mode for a specific file: vue-cli-service test:e2e --headless --spec tests/e2e/specs/actions.spec.js
We've pre-configured Cypress to place most of the e2e testing related files under . You can also check out how to configure Cypress via cypress.json.
Cypress doesn't load .env files for your test files the same way as vue-cli does for your application code. Cypress supports a few ways to define env variables but the easiest one is to use .json files (either cypress.json or cypress.env.json) to define environment variables. Keep in mind those variables are accessible via Cypress.env function instead of regular process.env object.
