Error running TestNG test

Also if it helps…I tried running the test by not using any TestNG annotation…and just used a public static void main (string[] args). It ran just fine that time and executed the tests on the device.

also I am NOT using any xml files to run the tests.

So far it seems that it MAY have something to do with the setup of my jar files or env variables ? (or something along the lines). I’m on a MAC by the way.
