Quizlet, a leading online learning community with over 30 million monthly users, transitioned to Cypress as their primary end-to-end testing framework after facing limitations with their previous Selenium-based tool, Capybara. The Quizlet team preferred a testing framework in JavaScript, their primary coding language, and found Cypress to excel in cross-browser support, debugging ease, and test runtime. Unlike Selenium, Cypress operates as a standalone framework built on Node, making it more efficient for their needs. With a supportive community and regular updates, Cypress has enabled Quizlet to efficiently run smoke tests on critical user flows and broader tests for system integration issues, ensuring their application remains reliable and functional for users.
