Learn about Cypress' new testing platform, which offers "native" debugging and time travel capabilities. Walk through the process of using Cypress, understanding its inner workings, and leveraging its features to deliver better, well-tested software. Gain insights into the advantages of Cypress over Selenium Webdriver, explore its BDD-style approach, and discover how to run, record, and debug tests effectively. Examine the Electron app, test runner, selector playground, and command log functionalities. Delve into performance tradeoffs, ambitious goals, and the importance of smoke tests. Conclude with Will's thoughts on JavaScript, Cypress, and his personal journey in the field.
