Selectors, Actions & Config

Basic Test

describe('Login Page', () => {
  it('user can log in', async () => {
    await browser.url('https://example.com/login');

    await $('#email').setValue('user@example.com');
    await $('#password').setValue('secret123');
    await $('button[type=submit]').click();

    // Built-in retrying assertion — tolerates async UI updates without
    // a separate explicit wait before checking
    await expect($('h1')).toHaveText('Welcome');
  });
});

// $ and $$ resolve lazily — click()/setValue() automatically wait for
// the element to exist and be interactable before running

wdio.conf.js

export const config = {
  runner: 'local',
  specs: ['./test/specs/**/*.js'],
  capabilities: [{ browserName: 'chrome' }],
  framework: 'mocha',   // or jasmine, cucumber
  reporters: ['spec', 'junit'],
  services: ['chromedriver'],
};
