What is Cypress?

Cypress is a front end automated testing application created for the modern web. Cypress is built on a new architecture and runs in the same run-loop as the application being tested. As a result Cypress provides better, faster, and more reliable testing for anything that runs in a browser. Cypress works on any front-end framework or website.
Cypress is a tool in the Javascript Testing Framework category of a tech stack.
Cypress is an open source tool with 30.4K GitHub stars and 1.8K GitHub forks. Here鈥檚 a link to Cypress's open source repository on GitHub

Jest

As we all know testing is an important part of any application. To assist with our testing we are going to use both Cypress and Jest. We feel these tools complement each other and will help us get good coverage of our code. We will use Cypress for our end to end testing as we've found it quite user friendly. Jest will be used for our unit tests because we've seen how many larger companies use it with great success.

When you think about test automation, it鈥檚 crucial to make it everyone鈥檚 responsibility (not just QA Engineers'). We started with Selenium and Java, but with our platform revolving around Ruby, Elixir and JavaScript, QA Engineers were left alone to automate tests. Cypress was the answer, as we could switch to JS and simply involve more people from day one. There's a downside too, as it meant testing on Chrome only, but that was "good enough" for us + if really needed we can always cover some specific cases in a different way.

In the company I will be building test automation framework and my new company develops apps mainly using AngularJS/TypeScript. I was planning to build Protractor-Jasmine framework but a friend of mine told me about Cypress and heard that its users are very satisfied with it. I am trying to understand the capabilities of Cypress and as the final goal to differentiate these two tools. Can anyone advice me on this in a nutshell pls...

Hello, I am currently looking for a tool for automation tests in order to implement it into our CI/CD pipeline for both web development but also for Android and iOS. I considered Cypress but I need compatibility with Safari. I have knowledge of Java, C#, and JavaScript so the language isn't an issue. Also looked into Nightwatchjs and Puppeteer but found these 3 above more interesting.

My main concern is:

  • Browser support - Desktop - needs to support Google Chrome, Safari, Firefox and Microsoft Edge (minimum)
  • Browser support - Mobile - Safari and Chrome (minimum)
  • App - Android and iOS

If possible i would like to avoid using another tool for mobile (like Appium)

What do you use? What is the one you recommend (even another from the ones mentioned)

Thank you very much for your help!

Cypress Alternatives & Comparisons

What are some alternatives to Cypress?
Selenium
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily, it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.
TestCafe
It is a pure node.js end-to-end solution for testing web apps. It takes care of all the stages: starting browsers, running tests, gathering test results and generating reports.
Puppeteer
Puppeteer is a Node library which provides a high-level API to control headless Chrome over the DevTools Protocol. It can also be configured to use full (non-headless) Chrome.
WebdriverIO
WebdriverIO lets you control a browser or a mobile application with just a few lines of code. Your test code will look simple, concise and easy to read.
Jest
Jest provides you with multiple layers on top of Jasmine.
