Need to add bracket in the tag for sig-windows. Also fix an issue: for
current testing structure, it first init driver and then set up the
framework. So when initialize the driver, it does not know what OS is
and we can not set up the capabilities correctly. Instead we have to add
all the capabilities and supported fs types including both linux and
windows. Later in the code, we will check the Node OS and decide how to
run the test.
