Sorry, assembly language speak. When something is TESTed it sets flags in the FLAGS register of the CPU. You can then check those flags to manage execution. In this case two XMM values (for this argument consider them float values) are TESTed. Then the game code checks to see if value 1 is before (<), equal (==), after (>), etc. value 2 and if so execution jumps to some other place.
