Do you need 3-wire romex to feed bedroom ceiling box by electrical code?
No, you can feed it with a 2 wire Romex + ground. It depends on what is mounted on the ceiling. If it is just a light all you need is 2 wire + ground Romex. However if it is a fan/light and you want to control each one independant of the other you will need to use 3 wire Romex + ground. This is of course if you have 2 seperate switches. You would then connect the red wire to the blue light wire and the black wire to the black fan wire. If you use 2 wire Romex just connect the blue and black fan/light wire to the black wire in the ceiling box.

What is the reason for glowing of light in electric tester?
A small current is flowing through the light. In an insulated screwdriver with a neon tester, you put your thumb on the top and touch the other end on to the wire. It's best to make sure your other hand is behind your back and that you are not touching anything else. A live wire will light the neon. But if the neon does not light, that does not mean the wire is safe to touch. The power must be turned off back at the main switch before anything is touched.

Put the end of the light bulb on the top of the battery, dont touch the wire to the top when the light bulb is on it because is either shocks you or doesnt work.
