What is the process to update and reread environment variables from a .env file in Playwright?

Answer

Updating Environment Variables in Playwright

First, create a .env file in your project directory and set your email variable, like so: [email protected].

Next, in your playwright.config.ts file, import and configure the dotenv package to read the .env file:

import dotenv from 'dotenv';
import path from 'path';

dotenv.config();
dotenv.config({ path: path.resolve(__dirname, '..', '.env') });

In your configuration options, you can now access your environment variables using process.env:

export default defineConfig({
  use: {
    baseURL:
      process.env.STAGING === '1'
        ? 'http://staging.ray.run/'
        : 'http://ray.run/',
    email: process.env.EMAIL,
  },
});

When you run your tests with npx playwright test, Playwright will use the updated values from the .env file.

Alternatively, you can set environment variables directly in your command line:

[email protected] npx playwright test

This will override the .env file. Playwright provides multiple ways to set and update environment variables, so choose the method that suits your needs best.
