Cypress.io is getting some traction these days and since my favorite FE superstar @bahmutov promotes it a lot I couldn't help myself but get my hands dirty. Writing FE tests was always a pain and Cypress is promising a painless experience.
Going through the docs definitely was painless. Documentation is spiced with lots of best practices and I would say it's a good read about the FE/E2E testing in general. But still... while they stress you should not log in by visiting the login page, Cypress doesn't work with OAuth/OpenID out of the box.
