/*
* In this test, GPIO7 is connected to one end of a 1kΩ current limiting
* resistor and GPIO8 is connected to the other end of the resistor.
*
* This test is part 2 of a two part test.
* For part 1 see dont-reconfigure-direction-part1.js.
*
* Part 1 sets the ouput to 1 and expects to read 1 on the input. Part 1
* doesn't unexport the GPIOs so that part 2 can can ensure that a Gpio output
* object can be constructed without modifying the value of the output. Part 2
* also expects to read one on the input. This is achieved by using the
* reconfigureDirection option.
