How do I use dotenv with Playwright Test to run tests against different environments in parallel?

Answer

Using dotenv with Playwright Test

To run tests against different environments in parallel, you can use the dotenv package to manage environment variables in your configuration file. First, create multiple .env files with different configurations, such as .env.staging and .env.production.

Install dotenv:

npm install dotenv

In your configuration file, import dotenv and call the config() method with the desired .env file path:

import { PlaywrightTestConfig } from '@playwright/test';
import * as dotenv from 'dotenv';
import * as path from 'path';

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

const config: PlaywrightTestConfig = {
  use: {
    baseURL: process.env.BASE_URL || 'https://ray.run',
  },
};

export default config;

To run tests against multiple .env files in parallel, pass different values for environment variables when running tests from the command line or CI/CD pipeline. For example:

ENV_FILE=.env.staging npx playwright test

In your CI/CD pipeline, like GitHub Actions or Travis CI, define multiple jobs with different values for environment variables and run them in parallel.

With dotenv and Playwright Test, you can easily switch between different configurations by passing appropriate values for environment variables when running tests from the command line or CI/CD pipeline.
