JavaScript Basics for Automation Engineer - A Complete Guide

 

1. JavaScript Basics for Automation

Even if you’re a Test Automation Engineer, you need to understand the basics of JavaScript.

Core Concepts

• Variables: let, const, var

• Data Types: String, Number, Boolean, Object, Array

• Operators: +, -, *, /, %, ===, !==, &&, ||

• Functions:

function add(a, b) {

    return a + b;

}

const multiply = (a, b) => a * b;

• Conditional Statements: if, else if, else, switch

• Loops: for, while, for...of, for...in

• Arrays & Objects:

const arr = [1,2,3];

const obj = { name: 'John', age: 25 };

• DOM Manipulation (if needed for front-end testing):

document.querySelector('button').click();

---

2. Setting Up Your Automation Environment

Prerequisites

• Install Node.js (comes with npm)

  node -v
  npm -v
  

• Install a code editor: VS Code recommended

Create a Project

mkdir automation-project

cd automation-project

npm init -y

---

3. Choosing an Automation Framework

There are several frameworks for JavaScript automation:

Popular Frameworks

1. Playwright

   • Modern, cross-browser automation

   • Supports JavaScript/TypeScript

2. Puppeteer

   • Headless Chrome automation

3. Selenium WebDriver (via WebDriverIO)

   • Traditional, widely used

4. Cypress

   • End-to-end testing, developer-friendly

We’ll focus on Playwright, which is widely used today.

---

4. Installing Playwright

• npm i -D @playwright/test

• npx playwright install

• @playwright/test – test runner

• npx playwright install – installs browsers (Chromium, Firefox, WebKit)

---

5. Writing Your First Test

Create a file: example.spec.js

const { test, expect } = require('@playwright/test');

test('example test', async ({ page }) => {

  await page.goto('https://example.com');

  const title = await page.title();

  expect(title).toBe('Example Domain');

});

Run the test:

npx playwright test

---

6. Playwright Concepts for Automation

• Selectors: page.locator('selector')

• Actions: click(), fill(), hover(), selectOption()

• Assertions: expect(locator).toHaveText()

• Waiting: page.waitForSelector(), await locator.waitFor()

• Screenshots & Videos:

await page.screenshot({ path: 'screenshot.png' });

---

7. Organizing Tests

• Page Object Model (POM)

  • Keeps locators and actions in a separate file

class LoginPage {

  constructor(page) {

    this.page = page;

    this.username = page.locator('#username');

    this.password = page.locator('#password');

    this.loginBtn = page.locator('#login');

  }

  async login(user, pass) {

    await this.username.fill(user);

    await this.password.fill(pass);

    await this.loginBtn.click();

  }

}

module.exports = LoginPage;

• Test Suite Structure

/tests

  login.spec.js

/pages

  login.page.js

---

8. Integration with CI/CD

• Run tests in Jenkins/GitHub Actions/GitLab CI

• Example GitHub Actions workflow:

name: Playwright Tests

on: [push]

jobs:

  test:

    runs-on: ubuntu-latest

    steps:

      - uses: actions/checkout@v3

      - uses: actions/setup-node@v3

        with:

          node-version: 20

      - run: npm install

      - run: npx playwright install

      - run: npx playwright test

---

9. Advanced Automation Topics

• Parallel Execution

npx playwright test --workers=4

• Data-Driven Testing

test.each([

  { user: 'user1', pass: 'pass1' },

  { user: 'user2', pass: 'pass2' }

])('login test', async ({ user, pass }) => { ... });

• Handling Popups/Alerts

page.on('dialog', dialog => dialog.accept());

• API Testing

const response = await page.request.get('https://api.example.com/data');

expect(response.status()).toBe(200);

---

10. Reporting and Debugging

• Playwright Reports:

npx playwright test --reporter=html

• Debug Mode:

npx playwright test --debug

• Tracing (record test run for debugging):

await page.tracing.start({ screenshots: true, snapshots: true });

await page.tracing.stop({ path: 'trace.zip' });

---

11. Best Practices

1. Use Page Object Model for maintainability.

2. Keep selectors unique and stable.

3. Use explicit waits instead of random sleep.

4. Integrate with CI/CD for automated execution.

5. Use environment variables for sensitive data.

6. Write reusable utility functions for repeated actions.

Git basic commands to work on Git Bash command promt

 

Steps to use Git commands on the Git Bash command prompt:

1. Create a new folder

2. Right click with mouse on the newly created folder, then you will be prompted with following snap

3. Click on Git Bash Here option
