What it is
Cypress is a testing tool that runs automated tests against anything that runs in a web browser. Developers use it to check that their web applications behave correctly, for example by simulating user actions and verifying results. The README describes it as fast, easy and reliable, and points to documentation for details.
- Install Cypress into a web project as a development dependency
- Write automated tests that run inside a browser against your app
- Run component tests for frontend framework components
Great for
- Developers who want automated browser tests for a web application
- Teams that already use npm, Yarn, or pnpm in their JavaScript projects
- People testing components from frameworks mentioned in the project topics, such as React, Vue, Angular, or Svelte
Not ideal for
- Non-developers looking for a no-code testing tool; the README assumes installing packages via a JavaScript package manager
- Projects that need to test native mobile apps; the README only describes browser-based testing
How to get it
- 1
Install with a package manager
Install with npm (dev dependency)
npm install cypress --save-devInstall with Yarn
yarn add cypress --devInstall with pnpm
pnpm add cypress --save-dev - 2
Run it
- Install Cypress into your project using one of the package manager commands above
- Open the official getting-started guide at https://on.cypress.io/install
- Write your first test following the documentation
- Run the tests using Cypress as described in the documentation
- 3
Get the most out of it
- Use Cypress Cloud to record test runs and track results over time, as referenced in the README
- Add a Cypress status badge to your project README to show test status
- Read the changelog at on.cypress.io/changelog to track new releases
- Review the contributing guide if you want to modify Cypress itself
Downloads
Strengths
- Installs with a standard package manager command (npm, Yarn, or pnpm)
- Open source under the permissive MIT license
- Large, actively maintained project with a published documentation site
Trade-offs
- The README is short on technical detail, so specifics must be checked in the official documentation
- Some features, such as the Cypress Cloud integration, are tied to a commercial hosted service
- Requires a JavaScript-based project setup to be most useful
