To use jsdom with Mocha, follow these steps:
- Install jsdom and mocha using npm:
1
|
npm install jsdom mocha |
- Create a test file with your test cases and import jsdom at the top of the file:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
const { JSDOM } = require('jsdom');
const assert = require('assert');
describe('Example test suite', () => {
let dom;
beforeEach(() => {
dom = new JSDOM('<!doctype html><html><body></body></html>');
global.window = dom.window;
global.document = dom.window.document;
});
afterEach(() => {
delete global.window;
delete global.document;
});
it('should test something', () => {
// your test cases using jsdom
assert.equal(document.body.children.length, 0);
});
});
|
- Run your tests with Mocha:
1
|
mocha your_test_file.js |
This setup allows you to use jsdom in your Mocha test cases to simulate a DOM environment for testing JavaScript code that interacts with the DOM.
