They are electronically tested while still inside the launch tube by Missile Technicians, for Ballistic Missiles aboard FBM submarines. Aboard Fast-Attacks, Torpedomen perform the same test on Tomahawk, Harpoon or Subroc missiles with an electronic diagnostic device. They are also actively tested by shooting exercise weapons at Naval ocean test ranges. This is how the boat and crew is certified for handling and launching the weapons it carries.
All test are performed inside the torpedo or launch tube. This is a direct result of the sinking of the submarine Scorpion in 1969. Though there continues to be speculation concerning her fate, one major conclusion was that she experienced a torpedo "hot run" - the term for a torpedo activating inside the torpedo room. In those days, the old Mk 37 torpedoes were also electronically checked, but they had problems with hot runs. Until the Scorpion accident, no previous occurrence had led to a casualty.
The primary evidence for a hot run scenario was her location and course on the bottom of the ocean. At the time, she was transiting home after a long Mediterranean deployment; when found, she was almost 180 degrees off course. This is consistent with torpedo shut-down procedures in a hot run scenario. All torpedoes have range activation features to keep them from becoming active too close to the shooting submarine - being sunk by your own torpedo was a big problem for US boats in WW2. In fact, the USS Tang was sunk by an errant torpedo.
One feature to deactivate the torpedo is to turn 180 degrees - if a torpedo errantly turns 180 degrees, it will automatically shut down before arming. The fact that every compartment of the Scorpion except the Torpedo Room was crushed meant that the TR was already flooded - meaning that they failed to shut it down before it armed and detonated.
After that, testing procedures for all weapons were changed so that required checks had to be performed inside a tube to eject a hot running weapon. However, the safety record of the current Mk-48 torpedo led the Navy to remove HR procedures over 20 years ago, when I was still riding boats.

What is a trident submarine?

What is SALT 1 treaty and what did it do?
It was a five-year agreement that froze the number of intercontinental ballistic missiles (ICBMs) and submarine-launched ballistic missiles (SLBMs) at 1972 levels. The treaty also included an agreement restricting the development and deployment of antiballistic missile defense systems (ABMs), which were designed to shoot down attacking missiles.
What is a submarine used for?
A submarine is used as a subsurface naval weapons platform, or as a tool of exploration and recreation. The latter may be manned or robotic, and have a wide range of characteristics and applications. They are usually operated from or with direct reliance on a support vessel of some kind. We've seen them carrying investigators to the deepest oceans, or surveying shipwrecks on the bottom of the sea. The former are usually sophisticated naval vessels capable of great range and extended independent operation. They can carry torpedoes to sink other vessels, or guided missiles to be launched at distant targets to deliver nuclear payloads. The newer munitions include cruise missiles which can be launched from the submarine, or anti-ship missiles which can also be launched from below the surface. Certainly there are a number of instances of "spooks" working with the submarine service in a number of espionage or "black ops" projects. It could be the insertion of a SEAL team, or the gathering of intelligence in various ways.
