Step 1 — Execution Target

Default local. If mentions "cloud", "TestMu", "LambdaTest" → cloud via WDIO LambdaTest service.

Step 2 — Framework

Core Patterns

Selectors

// ✅ Preferred
await $('[data-testid="submit"]').click();
await $('aria/Submit').click();
await $('button=Submit').click(); // text-based

// Chaining
await $('form').$('input[name="email"]').setValue('test@test.com');

// Multiple elements
const items = await $$('.list-item');

Basic Test (Mocha)

describe('Login', () => {
    it('should login successfully', async () => {
        await browser.url('/login');
        await $('[data-testid="email"]').setValue('user@test.com');
        await $('[data-testid="password"]').setValue('password123');
        await $('[data-testid="submit"]').click();
        await expect(browser).toHaveUrl(expect.stringContaining('/dashboard'));
    });
});

Page Object

class LoginPage {
    get inputEmail() { return $('[data-testid="email"]'); }
    get inputPassword() { return $('[data-testid="password"]'); }
    get btnSubmit() { return $('[data-testid="submit"]'); }

    async login(email, password) {
        await this.inputEmail.setValue(email);
        await this.inputPassword.setValue(password);
        await this.btnSubmit.click();
    }
}
module.exports = new LoginPage();

TestMu AI Cloud Config

// wdio.conf.js
exports.config = {
    user: process.env.LT_USERNAME,
    key: process.env.LT_ACCESS_KEY,
    hostname: 'hub.lambdatest.com',
    port: 80,
    path: '/wd/hub',
    services: ['lambdatest'],
    capabilities: [{
        browserName: 'Chrome',
        browserVersion: 'latest',
        'LT:Options': {
            platform: 'Windows 11',
            build: 'WDIO Build',
            name: 'WDIO Test',
            video: true,
            network: true,
        }
    }],
};

Wait Strategies

// Wait for element
await $('[data-testid="result"]').waitForDisplayed({ timeout: 10000 });

// Wait for condition
await browser.waitUntil(
    async () => (await $('[data-testid="count"]').getText()) === '5',
    { timeout: 10000, timeoutMsg: 'Count did not reach 5' }
);
