Many teams relish building applications with React these days. Composable components and unidirectional data flow with Redux create a solid foundation for modular applications. By this point, you know higher-order components, selectors, and render props like the back of your hand. But what about testing?
If you neglect to write React tests because you don’t know what to test, which types of tests provide the most value, or how to start testing, then this talk will guide your path. I explain the difference among unit, isolation, and end-to-end tests, and provide a general framework for how to test your application.
You will learn about the testing framework Jest, how to test-drive components with Enzyme for design feedback, the magic and trade-offs of snapshot testing, how to unit and integration test your reducer and actions, and how to test your entire application in a browser by simulating user scenarios. Of course, I offer both pros and cons to each type of test, so you and your team can discover what works best for you. You will also learn how to use our nifty testdouble.js library.
