Code Coverage Isn’t Enough: How UI Coverage Completes the Picture

Measuring Coverage Is Hard; We Made It Better Trying to understand how much of your application is tested can be an exercise in frustration—you're stuck relying on numbers that are hard to interpret, methods that don’t reflect real user activity, and reports that are a nightmare to collaborate on. But what if it didn't have to be this way? What if coverage could be actionable, intuitive, and reflective of what really matters—the user experience? That's why we built UI Coverage. Let's break dow Read more

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 going t

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 [https://on.cypress.io/continuous-integration#What-is-supported]. 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

Takeaways from Write the Docs + Open Help Cincinnati

This weekend I attended Write the Docs + Open Help Cincinnati [https://www.writethedocs.org/conf/cincinnati/2018/]. 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 [http://openhelp.cc/], which I was unable to attend. I work as the main contributor and maintainer

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 [https://github.com/cypress-io/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

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

Introducing Drew Lanham

When is the right time to bring in a CEO? This “Founder’s Dilemma” is something I’ve been considering for some time. After leading product development for Cypress and steering the company through two rounds of funding, eventually I realized trying to split my time between CEO and development duties was no longer feasible. Being merely an “adequate” CEO hampered our potential and my passion and vision has always belonged with building the product. I realized we’d reached the point where we needed

Sliding Down the Testing Pyramid

A good end-to-end test runner, like Cypress, can be very effective at performing integration tests and even at running unit tests. In this blog post I will show how to write view component tests for a Hyperapp application and how to unit test individual functions. The same approach can work for components written using other frameworks like Vue, React, Cycle, Svelte and others. End-To-End tests Recently I watched a screencast video [https://www.youtube.com/watch?v=w8liCoPsDIU] recorded by Alex
