A frontend Framework for building data-driven applications running in the browser on top of REST/GraphQL APIs, using ES6, React and Material Design. Previously named admin-on-rest. Open sourced and maintained by marmelab.
By default, react-admin acts as a declarative admin configuration: list some resources, define their controllers and, plug some built-in components or your own to define their fields or inputs.
Thus, unit testing isn’t really needed nor recommended at first, because the internal API of the framework is already tested by its maintainers and each custom component can be tested by its own by mocking react-admin.
