Thanks. That's another excellent point. I think I had it in my post outline and just forgot to put it in here. The Mogotest application is complex to set up.

Thanks. That's another excellent point. I think I had it in my post outline and just forgot to put it in here. The Mogotest application is complex to set up. For each version of IE you want to test, you need a separate Windows installation with that version of IE. To test Safari and iOS requires provisioning Macs (we used leased minis running VMs on ESXi). And the code itself runs on a Linux cluster. Since our cluster provisioning and deployment was encoded in the project rubber [1] configuration, that complication is somewhat mitigated. But the point remains: the application requires multiple machines across platforms to be remotely useful. [1] -- https://rubber.io/ https://rubber.io/
