Launching Cypress for the first time, you will be guided through decisions and configuration tasks so you can write your first passing test in minutes. No more configuration hell.

We believe that tests should be simple to write, read, and understand. Writing tests with Cypress is like giving descriptive commands to a real user to execute.

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

    // open the login modal
    cy.get('button').contains('Login').click()

    // fill in the form
    cy.get('input[type="email"]').type('[email protected]')
    cy.get('input[type="password"]').type('test123')

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

Use Cypress Studio to generate tests as you click and record each interaction with your application. Additionally, you can use our interactive selector playground to generate commands for matching any element.

Out-of-the-box, Cypress includes everything needed to set up your test suite. Spend less time managing drivers and dependencies, and spend more time delivering quality code.

Watch commands execute and your application under test side-by-side and in real time. Tests automatically re-run on file save for an instant feedback loop so that you can drive development with testing.

We go with the flow of the modern ecosystem. Continue using built-in browser tools that you know and love while your tests run. There’s no fidelity loss.

Understand why something failed with automatic DOM snapshots and videos of a full test spec run. This extra visibility makes debugging in headless mode (locally or in continuous integration pipelines) a breeze.

Find everything you need in one place. In-App workflows powered by Cloud insights to enable you to locally manage your project health and review, rerun, and debug tests that are recorded to Cypress Cloud.

We wrap all DOM queries with robust retry-and-timeout logic. When a test fails, we mimic a real user with built-in wait times and multiple attempts at asserting your tests in order to minimize false negatives / positives.

Cypress reduces flaky test results which are commonly present in other testing frameworks by isolating the state of each test and clearing the state of the browser before the next test runs and ensuring more trustworthy results.

Cypress automatically retries failed tests to mitigate flaky tests from failing entire test runs or CI builds. When paired with the Cypress Cloud, you’ll be able to detect, monitor, prioritize, and fix flake issues.

Our architecture doesn’t use Selenium or WebDriver. We built Cypress from the ground up for superior stability. Running in the same run-loop as your app allows us to control the entire automation process from top to bottom.
