APM comes with 19 onboard tests that will check all the major subsystems, so you can be sure they're working right, one by one.

To use them, type "test" in the CLI, and "help" to see all the different tests:

The available tests are:

"pwm: Shows the current output signals on each channel
"radio": Shows the current radio input readings on each channel
"failsafe": Shows current failsafe settings
"battery": Shows the current battery voltage if you have the voltage monitor hooked up
"relay": Tests the onboard relay (turns it on and off every five seconds; you should hear it faintly click)
"waypoints": Shows the currently programmed waypoints
"xbee": Shows incoming data from the Xbee wireless module, if one is connected
"eedump": Dumps the current data in the onboard EEPROM memory
"modeswitch": Shows current mode toggle switch position
"dipswitches": Shows current DIP switch positions
"adc": Shows raw output from the ADC chip, which gives raw sensor values
"gps": Shows the current data from the GPS module. Will be 0 if you don't have GPS lock
"rawgps": Shows raw output from the GPS module, useful in diagnosing GPS problems
"imu": Shows the current calculate x,y and z attitude
"gyro": Shows the raw gyro and accelermeter readings
"airspeed": Shows the data from the differential pressure sensor, if one is connected
"airpressure": Shows the data from the onboard absolute pressure sensor
"compass": Shows the data from the magnetometer, if one is connected and enabled
"current": Shows the data from the current sensor, if one is connected and enabled
