I have one nitpick, though, about the way you use Testing Library: While your reasoning behind using `getByTestId` to wait for the loader to disappear is sound, the concept behind Testing Library is to test apps the way the user uses them. Testing. Write tests to prevent regressions and write better code. Examples in this guide use global methods from Mocha, not Jest.. Internal. Material-UI has a wide range of tests so we can iterate with confidence on the components, for instance, the visual regression tests provided by Argos-CI have proven to be really helpful.

Fomantic UI treats words and classes as exchangeable concepts. Classes use syntax from natural languages like noun/modifier relationships, word order, and plurality to link concepts intuitively. Get the same benefits as BEM or SMACSS , but without the tedium. When writing UI tests, tasks like rendering, user events, or data fetching can be considered as “units” of interaction with a user interface. React provides a helper called act() that makes sure all updates related to these “units” have been processed and applied to the DOM before you make any assertions: The main goal for Karma is to bring a productive testing environment to developers. The environment being one where they don't have to set up loads of configurations, but rather a place where developers can just write the code and get instant feedback from their tests. Because getting quick feedback is what makes you productive and creative.
