End to end testing - Cypress basics

When you’ve made a change to your web-app, do you run it then click around the new bits to check it works? Good start, but instead of doing that yourself, do it in a faster, more comprehensive and automated way with an end-to-end (E2E) testing setup using Cypress . Here’s how.

E2E

End to End testing is testing your app as a user might - by clicking links, entering data, looking at the screen and checking everything is okay, but it’s scripted like a unit test and the results are checked with assertions. Like unit testing this allows you to build up a collection of comprehensive tests that easily detect for unexpected behaviours - not just in the results of functions in your app, but in the user experience of the app.
