When cy.lighthouse() command is run, Cypress opens a new browser tab

[cihanaygunes]

Hi,

A similar issue has been reported earlier with #67. But I will try to elaborate the issue that I am having.

What does not work?
I am working on implementing Cypress Lighthouse testing on my application with @cypress-audit/lighthouse plugin.

I followed the steps in here for installation and configuration.

The issue that I am having is that when lighthouse command is run, it opens a new browser tab and lighthouse report gets generated by running against the second tab.

Here are the steps that I make in lighthouse test.

1. I make a bunch of api calls to build a URL
2. Then that URL redirects to an authentication page where I input credentials and pass few more steps
3. Then land on the page page where I run lighthouse command

I pass the first 2 steps in Cypress spec file. When it comes to step 3, lighthouse command is run, however it opens a new browser tab with above-mentioned built URL in step one, and it redirects back to authentication page. So, the lighthouse test runs against the authentication page but not my application page.

How to reproduce?
I think this is already there. Any test will open a new browser tab.

Expected behavior
I expect lighthouse() command to run within the same Cypress browser instead of running on a separate browser tab or a way to pass the session information to the new tab.

Second Tab

Environment (please complete the following information):

• OS: Mac
• Chrome version: 119
• Cypress version: 13.5.1
• Lighthouse version: "@cypress-audit/lighthouse": "^1.4.2",

Any other information that may help fixing the issue?
Screenshots are belong to another url. I just wanted to show you the second tab is opened.

Just for context on how Cypress works now, since we made changes on how tabs are handled. cypress-io/cypress#28337

It may be beneficial to update this plugin to use the @cypress/puppeteer plugin if it does need to interact in a new tab. I'm not completely familiar with the implementation, so just adding some info.

@cihanaygunes just wondering if you ever got this to work? I have the puppeteer plugin installed, but I can't figure out how to have puppeteer control the new tab that opens with cypress audit because it opens and closes so fast.
