So, let’s get started and discover more about the Playwright’s function in test automation.

Exploring Playwright To Streamline Browser Automation For Modern App Development

Today, Playwright is widely used to automate browser tests across various platforms and web- browsers. This software uses modern technologies like Webkit and Chromium engines. These engines render web pages and handle interactions within web browsers. By utilizing these engines, Playwright testing companies benefit from their high reliability and efficiency. Further, Playwright offers an easy-to-use interface for managing browsers, thus ensuring that tasks get completed quickly, reliably, and with minimal complexity.

Why Choose Playwright For Web Automation?

The Playwright addresses common challenges in web automation, such as slow test execution, unreliable wait scenarios, excessive boilerplate code for browser setup, and difficulties with parallel execution. Playwright offers several advantages that make it a preferred choice for web automation, as explained below:

  • Ease of Installation: Playwright simplifies setup with a single command that downloads binaries for supported browsers such as Chromium, Firefox, and Webkit.
  • Core Concepts: Browser, Context, and Page, the playwright testing tool operates on these three core concepts.
  • Browser: Launches a browser instance (Chromium, Firefox, Webkit) using the Browser class.
  • Context: Enables parallelization via isolated browser contexts, akin to incognito sessions.
  • Page: Represents a tab or pop-up window within a context where test actions occur.
  • Cross-Browser Support: Playwright’s compatibility with multi-browser allows testers to create tests once and execute them across different browsers with minimal configuration. It reduces the development effort and ensures consistency in the results.
  • Playwright’s Auto-Wait Feature and Reliable Execution: One significant benefit of Playwright is its automatic wait function. This feature waits for the website’s parts to be downloaded before performing any action.
  • Custom Waiting in Playwright: Playwright provides testing automation companies with unique wait capabilities so they can bide their time till a selector becomes available. It is beneficial for scenarios like lazy page loading. Additionally, it supports waiting until specific network conditions are met.
  • Authentication Handling: Playwright simplifies authentication by enabling users to log in once and store session details and cookies within a context. This stored information can be utilized across all tests within that context, eliminating the need for multiple logins. Integrating this code into setup files (for Jest) or test fixtures (for a playwright-test runner) is essential to apply it consistently across context objects.
  • Resilient Selectors: The Playwright introduces more resilient selectors like text content and accessibility labels alongside standard selectors such as id, XPath, CSS, and class names.

Playwright saves login states for reuse across automation tests. So, Playwright testing enhances test efficiency by reducing repetitive tasks.

Zero Overhead And Fast Execution

With Playwright, each test runs in a new browser profile, ensuring isolation and faster execution without the overhead.

Dynamic Tooling Options

Playwright offers tools like Codegen for creating test scripts, Trace Viewer for detailed test analysis, and the Playwright Inspector for debugging and generating selectors.

Supported Browsers

Playwright supports various modern browsers, including Firefox, Chromium, Google Chrome, Microsoft Edge, and WebKit. It is regularly updated to maintain compatibility with the latest browser versions.

How To Set Up And Run Playwright Test Scripts?

Step 1: Create a New Directory In VSCode

Create a new directory, such as “PlaywrightDemo,” in Visual Studio Code (VSCode). This approach is also preferred even by leading Playwright testing companies.

Step 2: Open Directory In VSCode

Open the newly created folder in VSCode by selecting File > Open Folder and choosing the “PlaywrightDemo” folder.

Step 3: Open Terminal In VSCode

From the VSCode menu, click on Terminal> New Terminal to open a terminal window.

Step 4: Install Playwright

In the Terminal, enter the following command to initiate the Playwright installation:

```npm init playwright@latest```

Follow the prompts to provide necessary inputs. For this tutorial, we’ll use TypeScript.

This command performs the following actions:

– Creates Package.json

– Installs necessary npm libraries

– Sets up basic files and folders:

– “tests” folder: Contains test scripts (e.g., example.spec.ts by default)

– “.gitignore”: Helps with version control using Git

– “package.json” and “package-lock.json”: Track dependencies and create shortcuts for running tests

– “playwright.config.ts”: Global configuration file for Playwright testing tool, where options can be set

Step 5: Install Playwright Browsers

While Playwright can run on existing browsers, it’s recommended to install Playwright’s versions of Chromium, Firefox, and Webkit using the command:

```npx playwright install```

Step 6: Create Your First Playwright Test

Navigate to the “tests” folder and create a new test spec file, e.g., “demo.spec.ts.”

Here’s an example scenario for your test:



import { test, expect } from '@playwright/test';

test('Verify Login Error Message', async ({ page }) => {

await page.goto('');

await page.waitForSelector('text=Sign in', { state: 'visible' });

await'text=Sign in');

await page.waitForSelector('#user_email_login');

await page.type('#user_email_login', '[email protected]');

await page.type('#user_password', 'examplepassword');


const errorMessage = await (await page.locator("//input[@id='user_password']/../div[@class='error-msg']").textContent()).trim();

console.log("Browserstack Login Error Message: "+errorMessage);

expect(errorMessage).toBe('Invalid password');



Step 7: Execute Your Playwright Automation Testing

Modify the “playwright.config.ts” file to comment out the option that starts with “projects: [“.

Then, execute your Playwright test script using the following command:

```npx playwright test demo.spec.ts --headed```


– Specifies the test file to run (demo.spec.ts).

– Uses “–headed” to run in headed mode (visible browser).

– By default, Playwright tests run in Chromium.

Step 8: View The HTML Report

After running the test, an HTML report is generated in the “playwright-report” folder. To view the report, use the command:

```npx playwright show-report```

Test Case: Verify Job Code Auto-Population on Career Page

Test Steps:

1. Open’s careers page via “”.

2. Choose a random job listing and obtain its job code using a random function.

3. Click the “Apply now” button on the selected job listing.

4. Confirm if the job code is automatically filled in the form’s “edit-job-id” field.

Expected Result: The job code fetched in step 2 should match the value in the “edit-job-id” field, indicating successful auto-population.


To automate this test, we use the Playwright automation testing framework. Here’s the script (careers.spec.js) to automate testing:


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

test('Test Job Code', async ({ browser, page }) => {

// Open the careers page

await page.goto('');

// Find a random job teaser item

const teaserItems = page.locator('.career-openings-page-row.clearfix.views-row article');

const count = await teaserItems.count();

const randomTeaserItem = teaserItems.nth(Math.floor(Math.random() * count));

// Get job code from the teaser item

const jobCodeElement = await randomTeaserItem.locator('.field.field--field-job-code');

await expect(jobCodeElement).toHaveCount(1);

const jobCode = await jobCodeElement.innerText();

// Click on "Apply now" button

const jobLink = randomTeaserItem.locator('a');


const applyNowButton = await page.locator('#block-careerapplyblock').getByRole('link', { name: 'Apply now' });

const popupPromise = page.waitForEvent('popup');


const popup = await popupPromise;

await popup.waitForLoadState();

// Check if job code input field has correct value

const jobCodeInput = await popup.locator("#edit-job-id");

const jobCodeValue = await jobCodeInput.inputValue();

await expect(jobCodeValue).toEqual(jobCode);



To execute this test across different browsers, create a config file (playwright.config.js):


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

const config = {

projects: [

{ name: 'chromium', use: { ...devices['Desktop Chrome'] } },

{ name: 'firefox', use: { ...devices['Desktop Firefox'] } },

{ name: 'webkit', use: { ...devices['Desktop Safari'] } },



module.exports = config;


To run the test in Chrome, Firefox, and Safari, use the command:


npx playwright test --reporter=html


For a detailed report, use:


npx playwright show-report
