In addition to Max Schmitt's answer, here's 3 other ways to do it:

dotenv-cli

Add dotenv-cli to your dev dependencies then use it: dotenv playwright test (or npx dotenv playwright test if you're running this command outside of a package.json script).

require + NODE_OPTIONS

Use the --require Node.js option and NODE_OPTIONS to set it: NODE_OPTIONS=--require=dotenv/config playwright test.

require + npx

Use the --require Node.js option and npx to set it: npx --node-options=--require=dotenv/config playwright test (if you're using an old version of npx, you might need to replace --node-options by --node-arg)

You can use env-cmd:

// playwright.config.ts
import "dotenv/config";

import { defineConfig, devices } from "@playwright/test";
...

// package.json
{
  "scripts": {
    ...
    "test": "env-cmd -f .env.development --no-override playwright test",
    "test:staging": "env-cmd -f .env.staging --no-override playwright test",
    "test:production": "env-cmd -f .env.production --no-override playwright test"
  },
}

In addition: With env-cmd, the environment variables can be set in any format like .js or .json. Advanced usage details are here.

Add .env-cmdrc in the root folder. I preferred to use it for test commands only.

{
  "development": {
    "BASE_URL": "DEV_URL"
  },
  "staging": {
    "BASE_URL": "STAGING_URL"
  },
  "production": {
    "BASE_URL": "PROD_URL"
  }
}

In package.json:

{
  "scripts": {
    ...
    "test": "env-cmd --environments development --no-override playwright test",
    "test:staging": "env-cmd --environments staging --no-override playwright test",
    "test:production": "env-cmd --environments production --no-override playwright test"
  },
}

Here's an example of how I do it:

// playwright.config.ts 

import { PlaywrightTestConfig } from '@playwright/test';

if (process.env.NODE_ENV === 'development'){
  require('dotenv').config({path: '.env'});
}

const config: PlaywrightTestConfig = {
  // ...
}

You can put require('dotenv').config() inside your playwright.config.ts and then it will work, see here:
