For debugging purposes, it is often useful to be able to monitor a signal with an oscilloscope. For that purpose, it is helpful to provide access to the signals via test points, particularly with BGA devices where it might otherwise be impossible. Signals that are pulled up or down may also be probed at the resistor. Having a GPIO brought to a test point or an LED can be useful for debug, as well.
