TestCafe Automation Skill
Core Patterns
Basic Test
import { Selector } from 'testcafe';
fixture('Login').page('https://example.com/login');
test('Login with valid credentials', async t => {
await t
.typeText('#username', 'user@test.com')
.typeText('#password', 'password123')
.click('button[type="submit"]')
.expect(Selector('.dashboard').exists).ok();
});
Selectors
const submitBtn = Selector('button').withText('Submit');
const listItems = Selector('.item').count;
const nthItem = Selector('.item').nth(2);
const filtered = Selector('.item').withAttribute('data-status', 'active');
Page Model
import { Selector, t } from 'testcafe';
class LoginPage {
constructor() {
this.usernameInput = Selector('#username');
this.passwordInput = Selector('#password');
this.submitButton = Selector('button[type="submit"]');
}
async login(username, password) {
await t
.typeText(this.usernameInput, username)
.typeText(this.passwordInput, password)
.click(this.submitButton);
}
}
export default new LoginPage();
TestMu AI Cloud
See reference/cloud-integration.md for full cloud setup and shared/testmu-cloud-reference.md for capabilities.

Anti-Patterns
| Bad | Good | Why |
|---|---|---|
await t.wait(5000) | Smart assertions with timeout | Arbitrary delays |
| Deep CSS selectors | Selector().withText() | Fragile |
| No error screenshots | t.takeScreenshot() on failure | Missing debug info |
Quick Reference
| Task | Command |
|---|---|
| Run all | npx testcafe chrome tests/ |
| Run headless | npx testcafe chrome:headless tests/ |
| Run specific | npx testcafe chrome tests/login.js |
| Multiple browsers | npx testcafe chrome,firefox tests/ |
| Live mode | npx testcafe chrome tests/ --live |
| Screenshot | await t.takeScreenshot() |
| Resize | await t.resizeWindow(1280, 720) |
