Question on ensureCleanSession option for IE. Assuming we can run multiple IE tests in parallel (multiple IE sessions or instances) on same machine, does this clearing of cache apply across all the IE sessions/instances of the tests being run on same machine, or only to the individual driver instance calling that capability?

I had the same question for SafariDriver's version and was told best not to use this ensureCleanSession feature if running tests in parallel (multiple sessions/tests on same browser machine). So it is best used when only running a single instance per machine.

Wanted to get this clarified for IE as well.

It's unfortunate that these browsers are not like FF (and Chrome?) where you do get unique profiles/sessions per instance such that they all don't share the same cache.

What you could try is to run sessions under different users on the same machine, through multiple user switching. You should be able to do the same with Safari as well.

Thanks for the suggestion Likai. Could you elaborate on how one might run parallel IE/Safari tests (say deployed over Grid) on same node using multiple user switching. Or does that approach only work a certain way?

Would it be something like have multiple user accounts logged in to same machine (but one is active desktop while the others are backgrounded/locked in terms of Windows) but each one starts a node instance (supporting 1 IE/Safari browser) before being backgrounded? Or alternatively, we start multiple node instances on the logged in desktop/user, but for each instance we do "Run As" a particular user (on Windows) and for Mac assume use the terminal to switch to other user account and execute node instance?

Hi David,

I'm afraid I'm not an expert in Windows or Mac OS X admin, but what you suggested sounded reasonable, whichever works for you.
