Understanding how react-testing-library works with Kent C. Dodds
Share this video with your friends
Kent walks us through the internals of dom-testing-library and react-testing-library.
There is a lot of set-up and tear down when testing UI components. These two libraries take away a lot of the work required to test React components well.
Jest is commonly used in tandem with react-testing-library to assert results of your components. Jest simulates most browser apis with jsdom. react-testing-library helps you get values out of your components the same way your end users will.
