How to automate web app testing with Playwright

Testing web apps is tedious, time-consuming work, even when you have an automation framework to handle the heaviest of the lifting. Playwright, a web app test system originally developed by folks at Microsoft, simplifies many common web-app testing tasks by way of its intuitive syntax and object model. This video demonstrates using Playwright in Python to test a simple web app (although many other languages are supported for test suites, too).

thanks for making this video. i am looking for a way to use this with cursor. specifically, i want to make a ton of tests, and everytime cursor agent makes a change to my code it should run these tests to make sure it didn't break anything. if it did then it should try again, but once it makes the change and it passes all of the tests, it should write new tests to verify that it has implemented the change that has been asked for. i'm hoping that this will allow me to simply ask cursor agent to make a change and cursor can test the change itself and keep iterating until it really makes the change.
