I am currently working on a Playwright test script in TypeScript and I'm looking for a way to leverage variables from my .env file within the test. Does anyone know how this can be accomplished?
To enable environment variables in your Playwright tests, simply include require('dotenv').config() within your playwright.config.ts file. For more information on how to do this, refer to the following link:
Aside from Max Schmitt's response, here are three alternative methods to accomplish this:
To utilize dotenv-cli, integrate it into your development dependencies and execute: dotenv playwright test (or use npx dotenv playwright test if executing this command outside a package.json script).
Employ the Node.js option --require along with NODE_OPTIONS to establish it:
NODE_OPTIONS=--require=dotenv/config playwright testUtilize the Node.js option --require in conjunction with npx to configure it:
npx --node-options=--require=dotenv/config playwright test--node-options with --node-arg).
Allow me to demonstrate how I approach this task:
// my.test.config.ts
import { TestConfiguration } from '@my/test';
if (process.env.NODE_ENV === 'development'){
require('dotenv').config({path: '.env'});
}
const configuration: TestConfiguration = {
// ...
}
If you want to manage environment variables easily, consider using a tool like 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"
},
}
Furthermore:
Using env-cmd, you can configure environment variables in different formats such as .js or .json. For more advanced usage options, refer here.
Add a file named .env-cmdrc in the root directory specifically for managing test commands.
{
"development": {
"BASE_URL": "DEV_URL"
},
"staging": {
"BASE_URL": "STAGING_URL"
},
"production": {
"BASE_URL": "PROD_URL"
}
}
In your package.json file:
{
"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"
},
}
