USB/insert test fail

When you insert the USB key does the drive get mounted and the USB icon appear on the launcher?

Hi.

When I inserted pendrive, mounting was succeeded. Nautilus came up and
I could see the contents of the drive.

Thanks for commenting about my bug,
Chiba

From the time you click Test, you have 10 seconds to insert the key. Unfortunately, this also includes the time necessary for the system to recognize the key, load the proper drivers and mount the key. In some cases (such as a new key, fresh boot, fresh install, etc) it's quite possible to exceed the 10 second time limit while waiting for the system to initialize the key and register the event that the test is looking for.

The behaviour of the test is to watch for the insert event to occur and exit immediately on detection OR exit after 10 seconds if no detection occurred, I think a safe solution would be to bump the default up to 20 seconds. That way we should be guaranteed to get the events for even slow systems that trigger false failures without extending test time appreciably since the test is supposed to exit as soon as it registers the event.

Just to document this, here are two passing and failing insert and remove tests using removable_storage_watcher. Note that the passing tests are obvious and the failing tests take just a shade over 10 seconds of real time.
