With built-in retrying and customizable timeouts, Cypress sidesteps all of these flaky issues. Core Concept. Cypress wraps all DOM queries with robust retry-and-timeout logic that better suits how real web apps work. We trade a minor change in how we find DOM elements for a major stability upgrade to all of our tests.
Use the RWA to learn, experiment, tinker, and practice web application testing with Cypress. The app is bundled with everything you need, just clone the repository and start testing. Explore Cypress documentation for a comprehensive guide on efficient testing. Discover features, commands, best practices, and get started with Cypress today.
Cypress deprecated the use of Node.js 16.x in Cypress 13.0.0. We recommend that users update to at least Node.js 18.x. For related reasons, Cypress deprecates the use of Linux operating systems with library glibc versions 2.17 - 2.27. The Linux CLI command ldd --version displays your glibc version. Windows 10 and above (x64). Node.js
The Cypress team maintains the Real World App (RWA) , a full stack example application that demonstrates best practices and scalable strategies with Cypress in practical and realistic scenarios . The RWA achieves full code-coverage with end-to-end tests across multiple browsers and device sizes , but also includes visual regression tests , API tests, unit tests, and runs them all in an efficient CI pipeline .
Set up intelligent code completion for Cypress commands and assertions. Record your test results to Cypress Cloud for advanced features like parallelization, flake detection, and more. Check out the Real World App (RWA) for practical demonstrations of Cypress testing practices, configuration, and strategies in a real-world project.
Spec files. Test files are located in cypress/e2e by default, but can be configured to another directory. Test files may be written as: Cypress also supports ES2015 out of the box. You can use either ES2015 modules or CommonJS modules. This means you can import or require both npm packages and local relative modules.
Cypress Studio provides a visual way to generate tests within Cypress by recording interactions against the application under test. Cypress Studio is available only in end-to-end tests, and must be enabled via the e2e.experimentalStudio flag. For more details, read our blog post. Addresses #23461. Adds Svelte component testing support. This ...
By default, Cypress logs all requests that match any cy.intercept(), as well as all XMLHttpRequest s and fetch requests. You can use cy.intercept() to disable these logs by passing { log: false } in the second parameter: // disable Cypress's default behavior of logging all XMLHttpRequests and fetches.
Cypress Docker images provide a consistent environment tailored for use with Cypress. By choosing an appropriate Cypress Docker image, you determine the exact environment that your Cypress tests run in. This allows you to shield your workflows from version updates made by your CI provider, for instance if they update Node.js or browser versions.
