Test anything that runs in the browser with Cypress and GitHub Actions

The ecosystem for end-to-end (e2e) testing JavaScript applications has evolved a ton since I began working as a full-time engineer years ago. Granted, I do not write many tests today, I am growing a lot of appreciation for tools like Cypress that grasp the full browser experience in a test environment.

Last week I invited Gleb Bahmutov, VP of Engineering at Cypress, to chat and teach me how to leverage Cypress with GitHub Actions to quickly get a test environment up and running.

GitHub Action for running Cypress end-to-end tests

cypress-io/github-action renovate-app badge Action status

GitHub Action for running Cypress end-to-end tests. Includes NPM installation, custom caching and lots of configuration options.

Examples

What I learned in our conversation is that Cypress is not just an npm package. Through the CLI, you gain access to a base binary ready to run their testing system on all platforms (Linux, Windows, and Mac). When you start Cypress, it runs the binary to engage and work with your machine's default browser giving you the ability to see your test pass or fail in front of your eyes.

Towards the end of our conversation, we installed Cypress on my bdougie.live repo to get positive browser test results in my GitHub Action logs.

If you have not tried out browser testing in your project, I encourage you to do so today, you are only minutes away from having the confidence e2e tests, and you can also do it with Actions!

Watch Gleb walk me through getting it installed on my project. You can find the link below.

Except anything that involves multiple browser tabs or browsers such as Safari, Internet Explorer and mobile browsers.

And dealing with iframes is also difficult with Cypress, you have to summon 3 wizards, click your heels twice and pray to 7 Greek gods and it might just work, if you're lucky.

silly question, but can you test (using cypress for that matter) mouse movement?

Well, you could send / trigger mouse events from Cypress on.cypress.io/trigger

can you click a menu-item that appears if the menu appears using css :hover?
( I found this - stackoverflow.com/questions/488522... but I don't want to be forced to use jquery...)
