By caching and restoring cookies, localStorage, and sessionStorage data using the cy.session() command my Cypress tests now run considerably faster.

Playwright is an open source cross-browser end-to-end testing framework, maintained by Microsoft and developed by the team who created Puppeteer.

There may come a time where you have to cancel a network request as you no longer care for handling the response.
