Introducing the Cypress App

Write, run, and debug like a pro

Test modern apps directly in the browser

Watch your end-to-end and component tests run in real time as you develop your applications. Cypress’s simple, yet powerful API runs as fast as your browser can render content.

Write your first passing test in minutes

Installing Cypress and writing your first passing test is a breeze. There are no servers, drivers, or other dependencies to install or configure.

it('user should be able to log in', () => {
  cy.visit('/login')

  // fill in the form
  cy.get('input[type="email"]').type('[email protected]')
  cy.get('input[type="password"]').type('test1234')

  // submit the form
  cy.get('button').contains('Sign in').click()
  cy.contains('button', 'Logout').should('be.visible')
}) // @cy-startTyping

Debug failures directly in the browser

Because Cypress runs directly in the browser, you can debug failed tests using the in-browser developer tools you already know and love.

Eliminate flaky tests with ease

Cypress deterministically interacts with your application the same way as your users so you can discover intermittent bugs before your users do.

Cypress makes me feel about 10x as confident in my work. Just look at those tests go 🥰

Every day I learn something awesome new about @Cypress_io.

Its extensibility just makes it the super tool for new approaches and integrates in most environments. Especially when I compare it with other tools, it always feels easier and more stable to me.

Hey @Cypress_io just wanted to give you a big 👏👏👏 for the quality of your documentation. Thank you for the good work.

@BrentA1283

I've been meaning to express my gratitude to the incredibly talented people who built and maintain the docs @Cypress_io. From start to finish, it's such an incredible platform and so much of that is due to how easy it is to get into it via the top notch documentation! Thank you!

@HenrikJoreteg

Overall, settings up @Cypress_io's dashboard service and using GitHub actions to run all my Cypress tests in parallel has been a big win.

Cypress makes it possible to have the best of both worlds: a streamlined and stable testing infrastructure.

@Cypress_io is by far the best DX tool I have encountered.

@Cypress_io is an amazing tool. And the documentation is pure joy. It's like reading a great book...the more you read it, the more you love it. Thank you, @Cypress_io!

I need a relaxing morning.

I'll write some @Cypress_io tests.

I spend the last two days working with @Cypress_io: "A complete end-to-end testing experience"

I'm **really** impressed by this project. We feel the DX is super important for them... And it just works© 👏👏👏

I'm awestruck with the power of @Cypress_io. It makes the development and automation experience so awesome that you'll fall in love with it. With the updates more frequent than your sprint review, cypress is totally disrupting the market and is here to knock your socks off.

Cypress is a real game changer in e2e testing. It runs inside 2 containers on our stack. The setup was almost easy and its adoption by the team was immediate. Now our test coverage is growing fast.

Also mention the amazing test runner tool. @Cypress_io beats them all !

a-deal

@adilconstantine

Explaining to my 4 year old what I do for work & what automation is. So I showed him an automated @Cypress_io test & how its clicking and typing.

Me: I made the computer do the work while my hands are not touching it

My son: Oh so you can play with me while computer do work

@Cypress_io docs must be one of the best! 🤯 Well done.

It has it all: learning course, real world examples, best practices, even FAQ is impressive (it has questions I didn't even know I wanted to ask).

All open source too.

Opened a pretty big PR to our project in Hyperjump but our comprehensive @Cypress_io tests make me confident it won't break anything. So proud of my team 👏
