Using .env with Playwright Tests

Managing sensitive data like credentials, API keys, and configuration values securely is crucial when writing end-to-end tests with Playwright. One efficient way to handle this is by using a .env file. This approach separates configuration from code and enhances both security and flexibility.

A .env file is a plain text file where environment variables are stored in key-value pairs, such as:

ini

Copy

Edit

BASE_URL=https://example.com

USERNAME=testuser

PASSWORD=securepassword

To load these variables into your Playwright tests, you can use the dotenv package. First, install it:

nginx

npm install dotenv

Then, at the top of your playwright.config.ts or any setup file, add:

ts

require('dotenv').config();

Now you can access the variables using process.env in your tests:

ts

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

  await page.goto(process.env.BASE_URL!);

  await page.fill('#username', process.env.USERNAME!);

  await page.fill('#password', process.env.PASSWORD!);

  await page.click('button[type="submit"]');

});

Using .env ensures sensitive values aren't hardcoded or exposed in version control. You should also add .env to your .gitignore file.

In conclusion, integrating .env with Playwright tests makes your automation more secure, modular, and easier to manage across environments like staging, QA, and production.
