WebdriverIO Automation Skill

When to Use

Use this skill when you need generates WebdriverIO (WDIO) automation tests in JavaScript or TypeScript. Supports local and TestMu AI cloud. Use when user mentions "WebdriverIO", "WDIO", "wdio.conf", "browser.url", "$", "$$". Triggers on: "WebdriverIO", "WDIO", "wdio", "browser.$".

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' }
);

Limitations

• Use this skill only when the task clearly matches its upstream source and local project context.
• Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
• Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
