End-to-End Test Microsoft 365 Solutions with Playwright

In the past, I have written a couple of articles about end-to-end (E2E) testing your SharePoint/Microsoft Teams solutions with Cypress, Puppeteer, and Playwright. I was a big fan of Cypress, but I must admit that Playwright caught up and became my favorite tool for E2E testing. For me, the most significant advantage of Cypress was the visual UI for running your tests, but the main disadvantage was its use of an iframe, which caused issues for testing SharePoint and Microsoft Teams.
