Vitest Location Mock

(Fork of jest-location-mock, but for vitest)

Vitest hooks for JSDOM location mock

Description

Ever gotten the following error when using window.location.assign, reload, or replace?

Error: Not implemented: navigation (except hash changes)

This Vitest plugin fixes this error and mocks out window.location so it behaves similar to how does in the browser.

Features

• Mock and control window.location
• Relative URL support
• TypeScript extend expect support

Installation

npm install --save-dev vitest-location-mock

Usage

To start using Vitest Location Mock, extend expect and add hooks by importing the default export in your Vite setup file.

Setup

vite.config.js

export default defineConfig({
    setupFiles: [
        "./config/vitest-setup.js"
    ]
});

config/vitest-setup.js

// Mock `window.location` with Vitest spies and extend expect
import "vitest-location-mock";

Matchers

expect(location).toBeAt(url, [base])

Throws: When the URLs have a different absolute href.

it("should call assign with a relative url", () => {
    window.location.assign("/relative-url");
    expect(window.location).not.toBeAt("/");
    expect(window.location).toBeAt("/relative-url");
});
