Playwright - Test against different environments and different variables

Question

Im looking to use Playwright to test against a web page.

The system im working on has 4 different environments that we need to deploy against, for example the test urls may be

www.test1.com www.test2.com www.test3.com www.test4.com

The first question is how do I target the different Environment? In my playwright config I had a baseUrl but I need to override that.

In addition each environment has different login credentials, how can I create and override these as parameters per environment?

Since Playwright v1.13.0, there is a baseURL option available. You can utilise that in this way probably

In your config.js file, you can have this

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

const config: PlaywrightTestConfig = {
  use: {
    baseURL: process.env.URL,
  },
};
export default config;

Now in the package.json file, you can have the environment variables set in the test commands for various env in the scripts , like this

...
"scripts": {
  "start": "node app.js",
  "test1": "URL=www.test1.com mocha --reporter spec",
  "test2": "URL=www.test2.com mocha --reporter spec",
  .
  .
},
...

Similarly you can set the environment variables for the login credentials also and then pass them in the script in the same way the URL is passed.

Is there some other way to do this? For example if you hove some more properties that are environment specific. Is there a way to override or extend the configuration file instead of using env vars? — mismas, Mar 25 '22 at 21:08
in this case i pass ENVIRONMENT=test or ENVIRONMENT=production etc , then i use playwright GlobalSetup that loads from a json by the environment. — Andrea Bisello, Mar 31 '22 at 09:50

Another approach to this is to use a Bash script. I use something like the following to run tests across environments, to ensure that my Playwright tests will work in all environments they're run in -

#!/bin/bash

echo "Running tests against env 1";
ENV_URL=https://www.env1.com SOMESERVICE_ENV_URL=http://www.env1.com/scholarship npx playwright test $1;

echo "Running tests against env 2"

ENV_URL=https://env2.com SOMESERVICE_ENV_URL=http://env2.com:4008 npx playwright test $1;

echo "Running tests against env 3";

ENV_URL=http://localhost:3000 SOMESERVICE_ENV_URL=http://localhost:4008 npx playwright test $1;

And then run with ./myScript.sh myTest.test.ts

(In a Bash script, the first argument passed in is available via $1.)
