Reactjs - How to get window.location.pathname on test file using Jest?

In a Jest test file for a React component, you can mock window.location.pathname to simulate different paths and test how your component behaves. Here's how you can do it:

// Import the component you want to test import YourComponent from './YourComponent'; // Mock window.location.pathname delete window.location; window.location = { pathname: '/your/mock/path' }; // Your Jest test test('Your test description', () => { // Your test logic here });

In this example:

  • We import the component we want to test.
  • We delete the window.location object to remove any existing properties.
  • We create a mock window.location object with the pathname property set to the desired mock path.
  • Inside your Jest test, you can now assert how your component behaves based on the window.location.pathname.

This approach allows you to test how your React component responds to different paths without actually changing the URL in the browser.

Examples

  1. "ReactJS Jest test for window.location.pathname"

    • Description: This query looks for solutions to test React components using Jest while accessing window.location.pathname.
    • Code:
      // Sample test file using Jest and Enzyme import { shallow } from 'enzyme'; import React from 'react'; import MyComponent from './MyComponent'; describe('MyComponent', () => { it('renders correctly', () => { const wrapper = shallow(<MyComponent />); expect(wrapper).toMatchSnapshot(); }); it('gets window.location.pathname correctly', () => { const wrapper = shallow(<MyComponent />); expect(wrapper.instance().getPathname()).toEqual('/test/path'); // Assuming MyComponent has a method getPathname() that retrieves window.location.pathname }); });

  2. "ReactJS Jest window.location.pathname test"

    • Description: This query seeks guidance on testing React components with Jest while accessing window.location.pathname.
    • Code:
      // Sample test file using Jest import React from 'react'; import { render } from '@testing-library/react'; import MyComponent from './MyComponent'; test('window.location.pathname is correct', () => { const { getByTestId } = render(<MyComponent />); expect(getByTestId('pathname')).toHaveTextContent('/test/path'); // Assuming MyComponent renders a DOM element with data-testid="pathname" });

    • Description: This query looks for a test file example using Jest for a React component where window.location.pathname is accessed and tested.
    • Code:
      // Sample test file using Jest import React from 'react'; import { render } from '@testing-library/react'; import MyComponent from './MyComponent'; test('window.location.pathname is correct', () => { const { getByTestId } = render(<MyComponent />); expect(getByTestId('pathname')).toHaveTextContent('/test/path'); // Assuming MyComponent renders a DOM element with data-testid="pathname" });

  6. "ReactJS Jest test window.location.pathname value"

    • Description: This query is about testing the value of window.location.pathname in Jest for React components.
    • Code:
      // Sample test file using Jest import React from 'react'; import { render } from '@testing-library/react'; import MyComponent from './MyComponent'; test('window.location.pathname is correct', () => { const { getByTestId } = render(<MyComponent />); expect(window.location.pathname).toEqual('/test/path'); });

  7. "ReactJS Jest test for window.location.pathname"

    • Description: This query is for finding tests written with Jest to verify window.location.pathname in React components.
    • Code:
      // Sample test file using Jest import React from 'react'; import { render } from '@testing-library/react'; import MyComponent from './MyComponent'; test('window.location.pathname is correct', () => { const { getByTestId } = render(<MyComponent />); expect(getByTestId('pathname')).toHaveTextContent('/test/path'); // Assuming MyComponent renders a DOM element with data-testid="pathname" });
