Generate a .har artifact of the browser performance metrics in a session

Generate a .har artifact of the browser performance metrics in a session.   If a .har artifact were generated, then in theory I could use the download API to download the .har artifact and do assertions on the performance.    This is an artifact that would be similar to what is generated by using browsermob proxy but, without actually needing to use a proxy.   I know I am not the first person to ask for this but I did not see this request on this site and so I am adding it.

    The Sauce Labs Customer Support Team often asks customers to capture and send HAR files. We often have to tell them how to do it. If our product did this automatically, it would speed up resolution of support tickets.

    Just confirming that there's still value here. The overhead of running of something like a browsermob proxy on premise is even higher when using SauceLabs for the rest of the test cloud.

    Over the few months, we’ve been working on a new Extended Debugging functionality that allows our customers to collect networking (HAR files) and browser console log data for automated tests that are executed on Google Chrome & Mozilla Firefox. We are kicking off a closed beta today for anyone interested. Please reach out to me let us know in the comments.

    Thanks for scheduling this. Are you planning to support iOS Safari browser as well as part of this effort? If not when is this going to be planned?

    We are currently looking to support desktop browsers and support for mobile platforms hasn't been officially included on our roadmap but it is definitely under consideration.

    Is this complete? I would find this feature worth the cost for sure.

    I tried with new functionality it doesn't not capture response bodies. It's only capturing request/response  headers and  status
