The default status of TESTMODE pin is pull-up.
So, When TESTMODE pin is opened, generally we can say that there is no problem.

But, this is really important pin for MCU normal booting.
So, In order to guarantee pin status (high) from some noise or other environmental factor, pull-up on TESTMODE pin is required.

No, device will not go in testmode. The internal pull-up is always active during and after reset unless user software change TESTMODE port register.
