“Explore the different shapes and strategies...” that make sense to your specific project. @kalabro presented an idea that I love but rarely hear. The “Testing Mushroom” is what felt right for one project but it could be anything for yours. 🍄 What a great talk on testing.

Great talk by @kalabro about adding tests with @playwrightweb in a significant project at #ReactParis. 🍄 #TestingMushroom
