Launch chrome and firefox in the same test

[ajay-srikumar]

I am working on a automating a chat application. I need to open two instance of browsers and send messages between them. Is there a way in which I can login using chrome as one user and login using firefox as another user and test the chat functionality ?

I am able to open two instances chrome or two instance of firefox in a test, but unable to open one instance as chrome and the other instance as firefox.

This does not work

  test("Chat Test 1", async () => {
    const browser = await chromium.launch();
    const ff = await firefox.launch();

    const context1 = await browser.newContext();
    const context2 = await ff.newContext();

    const page1 = await context1.newPage();
    const page2 = await context2.newPage();

    await page1.goto("https://chat.com");
   await page2.goto("https://chat.com");
});

If you want to start two browser, you'll need to spin them up yourself instead of using the default fixtures:

const { firefox, chromium } = require('playwright');
test("two browsers in same test", async () => {
  const browser1 = await firefox.launch()
  const browser2 = await chromium.launch()

  const page1 = await browser1.newPage()
  const page2 = await browser2.newPage()
  
  // ...
})

This doesn't clean the browsers up after the test run though. I'd recommend you to set up your own fixtures for that: https://playwright.dev/docs/test-fixtures#creating-a-fixture

@Skn0tt , Thank you. I will try this. I also noticed that my browsers do not launch unless I specify the project param
--project=chrome when triggering the tests. Now when I follow the approach you have shared, should I still be providing the project param as I dont think it will accept both chrome and firefox as params.

Projects are a way of running the same test suite with different configuration. For most, it makes sense to have one project for each of the three big browser engines, and maybe some more for different resolutions etc.

In your case, you should probably have one project per browser combination you want to test. See https://playwright.dev/docs/test-projects for more info.

This solves my issue
