How to test modules written in GJS

["Zhuo.M" <mengzhuo1203 gmail com>]

Hi,
I know it might sounds like a retard or newbie question.
I have write some modules for my extension and I had to test them by
repeatedly  reload GJS(ALT+f2 r)
If I using tty console and run like "gjs *.js" , some of the modules
like "misc" or Main can't be imported.

Is there any way to test them separately? Any suggestion will be helpful to me.
