Rospy not working even though it is imported?

edit

My python script used to run but now does not work. It does not give any errors but only returns a blank terminal. It is also executable. Below is a simplified version of the code with the output. It seems the rospy functions are not working even though rospy is imported. When I wrote the script as an individual script, it worked fine but as soon as I started messing with it so that it could be included in the launch file, it stopped working. Any ideas?

 #!/usr/bin/env python
 import rospy
 import roslib

 print "test1"
 if __name__ == '__main__':
       print "test2"
       rospy.loginfo("test3")
       rospy.init_node('autodocking', anonymous=True)

OUTPUT:
test1
test2
