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', '[email protected]')
        .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();

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)`
