React Native Testing Library is a testing library for React Native inspired
React Testing Library. Because React Native does not run in a browser
environment, the core queries are implemented independently, unlike other
wrappers that use
DOM Testing Library as the base. You'll find much more
information about the library, including examples, on the project sites:
npm install --save-dev @testing-library/react-native
You want to write maintainable tests for your React Native components. As a part of this goal, you want your tests to avoid including implementation details of your components and rather focus on making your tests give you the confidence for which they are intended. As part of this, you want your testbase to be maintainable in the long run so refactors of your components (changes to implementation but not functionality) don't break your tests and slow you and your team down.
The React Native Testing Library (RNTL) is a lightweight solution for testing
React Native components. It provides light utility functions on top of
react-test-renderer, in a way that encourages better testing practices. Its
primary guiding principle is:
The more your tests resemble the way your software is used, the more confidence they can give you.
This Project is tested to work with Jest, but it should work with other test runners as well.
