Practice real frameworks

Hands-on Cypress exercises that mirror real engineering work — from core fundamentals to the patterns interviewers actually probe. Every challenge is graded automatically and mapped to a skill below.

Cypress runs inside the browser, so tests see the same DOM and network the app does. These challenges cover selecting elements the way a user would, waiting on state rather than on time, stubbing network calls, keeping suites fast, and the discipline that stops end-to-end tests becoming the flakiest thing in CI.
