Mock window.location.search
in a TypeScript React project using React Testing Library and Jest, you can follow these steps:
-
Install the necessary packages if you haven't already:
npm install @testing-library/react @testing-library/jest-dom jest @types/jest --save-dev
-
Create a setup file for Jest to configure the global
window.location.search
mock. In the root of your project, create ajest.setup.js
file (orjest.setup.ts
if you are using TypeScript). -
In the
jest.setup.js
(orjest.setup.ts
) file, define the mock forwindow.location.search
:// jest.setup.js (or jest.setup.ts) Object.defineProperty(window, 'location', { writable: true, value: { search: '' }, });
This code snippet sets up a mock for
window.location
with an initial value for thesearch
property as an empty string. This allows you to override this value during your tests. -
Update your Jest configuration in the
package.json
(orjest.config.js
for a separate configuration file) to include the setup file:// package.json { "jest": { "setupFilesAfterEnv": ["<rootDir>/jest.setup.js"] } }
This tells Jest to execute the setup file before running the tests.
-
Now, in your test files, you can use React Testing Library and Jest as usual. To mock the
window.location.search
for a specific test, you can set the desired value before rendering your component:// YourComponent.test.tsx (or .test.ts, .spec.ts, etc.) import React from 'react'; import { render } from '@testing-library/react'; import YourComponent from './YourComponent'; describe('YourComponent', () => { it('should render with a custom search query', () => { // Set the desired value for window.location.search Object.defineProperty(window, 'location', { writable: true, value: { search: '?query=test' }, }); // Now, render your component const { getByText } = render(<YourComponent />); // Add your assertions const element = getByText('Your Component Content'); expect(element).toBeInTheDocument(); }); });
In this example, the
window.location.search
is mocked with a custom query string (?query=test
) before rendering theYourComponent
.
By following these steps, you should be able to mock window.location.search
in your TypeScript React project using React Testing Library and Jest. Remember to customize the value of window.location.search
according to your test scenarios.

thanks chatGPT? 😂🤣
Thanks. Not that easy to make it work with typescript 😅
Mock window.location.search
in TypeScript:
global.window = Object.create(window);
Object.defineProperty(window, 'location', {
value: {
search: '?query=phone',
},
});
Not working with React Testing Library
Then in my
<Component
, Iconsole.log(window.location.search)
and it shows up undefined
