![]() ![]() Once created, let's move into the project's directory, and start the application: $ cd router-sample $ npm start Let's start out by creating a simple React application via the command line: $ npx create-react-app router-sample In this guide, we'll take a look at how to create routes in a React application, programmatically navigate between routes, as well as send and retrieve data between them, using React Router. React is a massively popular library for front-end development used to create highly responsive user interfaces, and naturally, it has its own Router, which performs Client-Side Routing - the react-router-dom. Client-Side Routing is used instead - to route towards resources to load another part of the program or structurally change the application's entire view if needed, when an action (such as clicking a button or link) is performed. It’s fairly easy to test different hooks using the RTL built-in methods only.Pages on modern websites, and especially Single-Page Applications (SPAs) do not follow the traditional method of loading new pages completely whenever something changes on them. The RTL now includes built-in methods for testing hooks. To use the userEvent object, you need to install the package as an additional dependency.Īs I mentioned earlier, you don’t need to use the library anymore with React 18 and above. The path prop is the URL path that the route should match, and the component prop is the component that should be rendered when the route matches.įor example, the following code would add a route that matches the / path and renders the Home component: import )) The Route component takes two props: path and component. Once you have installed the package, you can import the Route component from it. To add routes to your React app, you need to install the react-router-dom package. You can use useNavigate to go to a specific path or move back and forth in the browser history. React Router v6+ now uses the useNavigate Hook instead of the useHistory Hook. Testing hooks with React Testing Library.Using the fireEvent and userEvent methods.Testing query parameters with useLocation.Testing React routes and the useNavigate Hook.Testing the useNavigate Hook with jest.mock.We will unit test the routes and briefly discuss the different features that RTL offers to simplify the process of making components route-aware. In this article, we will cover testing scenarios of the useNavigate Hook from React Router 6 with RTL and Jest. Using React Testing Library, popularly known as RTL in the community, is the recommended way to test your apps because it is actively maintained, well-documented, fast, flexible, and powerful enough to write comprehensive and reliable tests.įrom React 18 onwards, React Hook Testing Library is included in the React Testing Library, and you can access it only through RTL. Rather than work like a test runner, this testing library requires a tool like Jest to implement automated testing in React. React Testing Library is a lightweight solution that provides a virtual DOM to interact with and verify the behavior of a React component. Testing the React Router useNavigate Hook with React Testing LibraryĮditor’s note: This article was last updated by Rahul Chhodde on to include information the React fireEvent and userEvent Hooks, as well as testing the React query parameters.
