AI(5 features)
AI-powered summaries that help you instantly understand test intent and what went wrong with failed tests in CI.
AI-powered summaries of test failures to quickly understand what went wrong.
Use cy.prompt to describe what you want to happen in plain language. Cypress AI generates the code for you and self-heals tests by regenerating them only when necessary.
AI-powered self-healing capability that regenerates tests only when necessary, maintaining test stability over time.
AI guides you in Cypress Studio as you record and edit your test. Studio AI suggests selectors, assertions, and test steps, reducing trial and error.
Debugging(5 features)
Continue using built-in browser tools that you know and love while your tests run with no fidelity loss.
Rewind time with Test Replay to directly inspect the DOM, network events, and console logs exactly as they ran in CI.
Time travel to see your application's behavior during test execution step-by-step. Hover over commands to see which elements Cypress acted upon.
Every AI-generated step appears in the Command Log with full time-travel debugging. Cached runs execute as quickly as hand-written tests.
Quickly identify and debug failures with visual context and screenshots.
Stability(5 features)
Never add arbitrary waits or sleeps to your tests. Cypress automatically waits for commands and assertions before moving on.
Built-in architecture that doesn't use Selenium or WebDriver. Running in the same run-loop as your app allows superior stability.
Cypress automatically retries failed tests to mitigate flaky tests from failing entire test runs. When paired with Cypress Cloud, detect, monitor, and fix flake issues.
Cypress isolates the state of each test and clears the state of the browser before the next test runs, ensuring more trustworthy results.
Built-in retry-and-timeout logic that wraps all DOM queries with robust retry mechanisms to minimize false negatives and positives.
Support(3 features)
Dedicated premium support from Cypress team for enterprise customers.
Access to Cypress product roadmap and feature planning insights.
Dedicated technical consultant who specializes in Cypress to optimize testing strategies and provide best practice guidance.
Testing(3 features)
Isolated component testing capabilities that allow testing individual UI components in isolation.
Natural language commands for interacting with your application during testing.
Full end-to-end testing capabilities to test complete user workflows across your application.
