'''Experiment'''
**Experiment**
* It attempts to do a TCP connect to the bridge IP:Port
* It attempts to do a TCP connect to the bridge IP:Port
* It attempts to make an SSL Handshake with the IP:Port pair
* It attempts to make an SSL Handshake with the IP:Port pair
* It attempts to do a full Tor connection to the bridge
* It attempts to do a full Tor connection to the bridge
'''Control'''
**Control**
Based on which one of the previous operations fail, the test will return through what means the bridge is being blocked.
