Cypress is software to create tests for modern web applications, debug them visually, and automatically run them in continuous integration builds.
This software lets you write all types of tests: End-to-end tests, component tests, integration tests, and unit tests.
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.
This is free and open source software.
Key Features
- No servers, drivers, or other dependencies to install or configure.
- Debug failed tests using the in-browser developer tools you already use.
- Deterministically interacts with your application the same way as your users so you can discover intermittent bugs before your users do.
- Easily integrate Cypress with your current CI provider. Run Cypress in CI and you will know as soon as there is a failure.
- Time Travel: Cypress takes snapshots as your tests run. Hover over commands in the Command Log to see exactly what happened at each step.
- Debuggability: Stop guessing why your tests are failing. Debug directly from familiar tools like Developer Tools.
- Automatic Waiting: Never add waits or sleeps to your tests. Cypress automatically waits for commands and assertions before moving on. No more async hell.
- Spies, Stubs, and Clocks: Verify and control the behavior of functions, server responses, or timers. The same functionality you love from unit testing is right at your fingertips.
- Network Traffic Control: Easily control, stub, and test edge cases without involving your server. You can stub network traffic however you like.
- Consistent Results: The architecture doesn’t use Selenium or WebDriver.
- Screenshots and Videos: View screenshots taken automatically on failure, or videos of your entire test suite when run from the CLI. Record to Cypress Cloud to store them with your test results for zero-configuration debugging.
- Cross browser Testing: Run tests within Firefox and Chrome-family browsers (including Edge and Electron) locally and optimally in a Continuous Integration pipeline.
- Smart Orchestration: Once you’re set up to record to Cypress Cloud, easily parallelize your test suite, rerun failed specs first with Spec Prioritization, and cancel test runs on failures with Auto Cancellation for tight feedback loops.
- Flake Detection: Discover and diagnose unreliable tests.
