Cypress Documentation
Cypress makes it quick and easy to start testing, and as you begin to test your app, 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.
Introduction to Cypress | Cypress Documentation
Cypress doesn't kick off the browser automation until the test function exits. Mixing Async and Sync code Remembering that Cypress commands run asynchronously is important if you are attempting to mix Cypress commands with synchronous code. Synchronous code will execute immediately - not waiting for the Cypress commands above it to execute.
Install using npm, yarn, or pnpm - Cypress

Changelog: Cypress App | Cypress Documentation
Changelog 14.0.0 . Released 1/16/2025. Summary: Cypress v14.0.0 improves performance of component testing and adds support for new framework and dev server versions. v14.0.0 also includes breaking changes to cy.origin that are necessary to handle Chrome's deprecation of document.domain injection, which should fix issues for some users in recent Chrome versions.
Best Practices | Cypress Documentation
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 ...
Writing and Organizing Tests | Cypress Documentation
When Cypress starts executing the first test, the beforeEach hook fails. Now the first test is marked as failed. BUT if the beforeEach hook failed once, why would we execute it again before the second test? It would just fail the same way! So Cypress skips the remaining tests in that block, because they would also fail due to the beforeEach ...
Command Line - Cypress
Prints the installed Cypress binary version, the Cypress package version, the version of Electron used to build Cypress, and the bundled Node version. In most cases the binary and the package versions will be the same, but they could be different if you have installed a different version of the package and for some reason failed to install the ...
Assertions in Cypress: A Guide | Cypress Documentation
Cypress bundles the popular Chai assertion library, as well as helpful extensions for Sinon and jQuery, bringing you dozens of powerful assertions for free. tip If you're looking to understand how to use these assertions please read about assertions in our Introduction to Cypress guide.
intercept | Cypress Documentation | Cypress Documentation
By default, Cypress logs all requests that match any cy.intercept(), as well as all XMLHttpRequests and fetch requests. You can use cy.intercept() to disable these logs by passing { log: false } in the second parameter:
