how i can test my android game ?

hello guys , how i can test my android game on my computer without Building and installing it on my android device .
for example i want to test touches or GUITexture Scale and Other things
should i Build and install the game on my android every time i want to test something ?

There’s a cool app called Remote. They updated it a week ago and now it works just great. You can find a manual here
It allows you to play your game on an android without building/installing it.



Also make sure you use 4.5 + version of Unity3D
