Simple example of a browser test using Mocha, Chai and WebdriverIO

test.spec.ts

import { remote } from 'webdriverio';
import { expect } from 'chai';
import { describe, it, before, after } from 'mocha';

describe('Mugshot README', () => {
  /* BROWSER SETUP */
  let browser!: ReturnType<typeof remote>;

  before(async () => {
    const options = {
      hostname: 'localhost',
      capabilities: { browserName: 'chrome' }
    };

    browser = await remote(options);
  });

  after(async () => {
    await browser.deleteSession();
  });
  /* END BROWSER SETUP */

  it('should have a logo', async () => {
    await browser.url('https://github.com/NiGhTTraX/mugshot/blob/master/README.md');

    const logo = await browser.$('img[alt=logo]');

    expect(await logo.isExisting()).to.be.true;
  });
});
