Add your missing tests faster, with Test Generation in UI Coverage

Today we are proud to launch AI-powered Test Generation in Cypress Cloud, to help you quickly add tests for the untested elements detected in UI Coverage reports, in a way that follows your existing practices and conventions.

Cypress Halloween Theme

A good tool can become a great tool when users make it their own through customization. In this blog post I will explain how to customize the Cypress test runner’s appearance through user space color themes. Since it is the season, we have prepared a dark and spooky Halloween color theme that might scare all your bugs away! When Cypress executes your end-to-end tests, the application under test is placed in an iframe element. The tests themselves are placed into another iframe to isolate them f

We're officially out of beta!

It’s been over four years since our first commit. Since then, we’ve seen Cypress achieve widespread and rapidly growing adoption. It’s now been downloaded more than 2.5 million times, with thousands of organizations recording millions of tests per month. And today, we’re thrilled to announce that Cypress has officially left beta. 🎉 To keep up, we’ve expanded our engineering team, while working hard to grow a community that helps thousands of QA engineers and developers in more than 90 coun

Run Your End-to-end Tests 10 Times Faster with Automatic Test Parallelization

I have no patience waiting for a lot of Cypress end-to-end tests to finish running on CI. Just sitting and waiting … staring at the CI badge. Any run taking longer than a minute feels like an eternity. Our Cypress development team felt this pain and decided to do something about it. Today we have a solution that slashes those waiting periods - it is automatic test file load balancing across multiple CI machines using a single --parallel flag. #Load-BalancingLoad Balancing By default cypress run

Setting up Bitbucket Pipelines with proper caching of NPM and Cypress

This is a guest post from Ondřej Janošík, co-owner of Notum Technologies, full-stack developer and clean code enthusiast based in the Czech Republic. Bitbucket Pipelines & Deployments is integrated CI/CD for Bitbucket Cloud that’s trivial to set up, automating your code from test to production (at least that’s what the official site says). However, setting up your pipelines with right commands and right caching in order to be as fast as possible requires some time. In this article, I am g

Record Test Artifacts from any Docker CI

We worked hard to make sure the Cypress Test Runner could be compatible with every continuous integration system. Jenkins, Travis, Circle, Zeit Now, Google Cloud Build, or your own homegrown CI system - they should all work with zero or minimum effort. We also worked hard to make our Dashboard Service particularly useful in collecting and showing all of your test artifacts in a single place. Test artifacts When you execute cypress run, the end-to-end tests produce artifacts for each spe

Takeaways from Write the Docs + Open Help Cincinnati

This weekend I attended Write the Docs + Open Help Cincinnati. Write the Docs + Open Help is an event that brings together documentation contributors to share and learn from one another. The weekend included a day of talks and day of unconference sessions and lightning talks. It also included three days of documentation sprints led by Open Help, which I was unable to attend. I work as the main contributor and maintainer of Cypress’ documentation. My background is in web design and more recently

Fast Tests, Tiny Docker Image

If the Cypress Test Runner were a person, its best friend would be a person named Docker. Really, Cypress and Docker work so well together! For example, all our CI builds are using cypress-docker-images to include all necessary dependencies in order to successfully install and run Cypress tests. Just run npm ci and cypress run and you are good to go. FROM cypress/base:10 RUN npm install # or even better: RUN npm ci RUN $(npm bin)/cypress run We use this approach to run a lot of te

JSON Schemas are your True Testing Friend

⚠️Please note: This article refers to the json-schemas package which is no longer supported. The repository has also been archived as a result. We use JSON schemas to describe the data flowing through our system, document API routes, test server code and even validate fixtures used during end-to-end testing. This long(ish) blog post describes in detail how we did this. Introduction At Cypress we have 3 large pieces of software: * The Cypress Test Runner, an Electron desktop applicati
