Why Cypress?
In a nutshell
Cypress is most often compared to Selenium; however Cypress is both fundamentally and architecturally different. Cypress is not constrained by the same restrictions as Selenium
Features
Here is a list of things it can do that no other testing framework can
- 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. Our readable errors and stack traces make debugging lightning fast
- 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: Our architecture doesn't use Selenium or WebDriver. Say hello to fast, consistent and reliable tests that are flake-free
- Screenshots, Videos, and Test Replay: View screenshots taken automatically on failure, or videos, if enabled, of your entire test suite when run from the CLI
- Cross Browser Testing: Run tests within Firefox and Chrome-family browsers (including Edge and Electron) locally and optimally in a Continuous Integration pipeline
Cypress in the Real World
you'll often wonder if you're using best practices or scalable strategies
To guide the way, the Cypress team has created the Real World App (RWA), a full stack example application that demonstrates testing with Cypress in practical and realistic scenarios
