๐ŸŽฅ Playwright Installation & Test Execution Using JavaScript – Step-by-Step Guide

Pre-requisites

The following two items should be installed:

  • Node.js
  • VS Code

Playwright Installation & Test Execution Using JavaScript (Step-by-Step)

✅ Step 1: Create a Project Folder

Open your file explorer or terminal and create a new folder:

mkdir PlaywrightTest

Navigate into the folder:

cd PlaywrightTest

✅ Step 2: Open Folder in VS Code

Open Visual Studio Code. Click File → Open Folder and select the PlaywrightTest folder.

✅ Step 3: Initialize Playwright

Open the integrated terminal in VS Code:

  • Shortcut: Ctrl + ~ or use View → Terminal

Run the following command:

npm init playwright@latest

Follow the prompts:

  • Select JavaScript
  • Keep the default test folder (tests)
  • Choose GitHub Actions workflow (optional)
  • Press Enter to install browsers (Chromium, Firefox, WebKit)

After installation, the following will be created:

  • package.json
  • playwright.config.js
  • tests/ folder with example tests
  • .vscode/ (optional)

✅ Step 4: Run Your First Test (Using CLI)

Playwright includes a sample test file example.spec.js in the tests folder. Run all tests using:

npx playwright test

๐Ÿ’ก Note: This will run all tests inside the tests folder.

✅ Step 5: View Test Report

After tests complete, view the HTML report:

npx playwright show-report

✅ Step 6: Run Test in Specific Browser

To run in Chromium only:

npx playwright test --project=chromium

To run with browser UI (headed mode):

npx playwright test --project=chromium --headed

✅ Step 7: Run a Specific Test File

To run only one test file:

npx playwright test tests/example.spec.js --project=chromium

With headed mode:

npx playwright test tests/example.spec.js --project=chromium --headed

✅ Step 8: Folder Structure After Setup


PlaywrightTest/
│
├── tests/
│   └── example.spec.js       # Sample test file
