It is not the eValid browser cache you need to delete (that
may be a good thing to do anyway), but you need to resent
the file system.
If test a runs and adds a file to the file system (whcih is
what you see in the Explorer file system display) then the
next time that test runs the files will be in a different place...
resulting in non-reliable playback.
You are altering the state of the test object and expecting
it to have not been altered...your test will fail unless
you start at a known state every time...
