SessionStorage values not honored in new Lighthouse tab about cypress-audit HOT 7 CLOSED

As an update....

I have found a workaround by using Lighthouse's custom gatherers/audits. There's a lifecycle hook in the custom gatherer (beforePass) that runs in the new tab before the url is visited for the audit. At this point, we can add in any needed sessionStorage values which will be present on the tab once the url is visited / app is loaded.

I'll update my repo I referenced above with the workaround and post here once that's done. Examples are usually helpful!

That all being said, it would be really cool if this plugin had an option to pass in a function that could run in the new Lighthouse before visiting the URL without having to implement this fake custom gatherer / audit. I'll leave that decision up to you :)

I'll try to take a look when I'll have some spare time 😊 New job is taking a bunch of my time 😅 (and thank you for the complete issue and explanations, really appreciated 🙏🏻 )

https://github.com/olyhaa-aetna/simple-auth-example has been updated to include the custom gatherer and audit which populates sessionStorage with values before the Lighthouse scan is run.

@olyhaa-aetna Can you try with the workaround from this issue #65 (comment)?

Hi @MuckT!

It looks like that workaround uses localStorage to remember login credentials between tests. However, our app uses sessionStorage.

We already have the tokens in the sessionStorage carry over in-between tests via running in the before/ after of each test. This seems to be working fine (from the perspective of the Cypress tests). However, these are not run in the new Lighthouse tab, so the session data is not transferred over.

We are never visiting an external url for authentication - we just store a mocked token in the sessionStorage.

Oh wow, very nice workaround 🤯 . And thank you so much for providing this exampe 🙏🏻 . Would you mind if we (you or I, depending if you want to make the PR) add a link to the example to orientate people that are using session storage?

Thanks for the amazing example, again 🙏🏻

I'm closing this issue since you've found a way to fix it. I will add a link to your repo in the documentation :)
