"Run Unit Tests" option is not there in VS 2013

I am watching a video tutorial for unit testing. In that tutorial, when the lecturer clicks a right-click on Unit test class, one of the options there is "Run Unit Tests" whereas I am not getting that option.

Here are the options my VS showing:

Another thing is, when he uses the name of a class / method which does not exist, a bulb appears on the left side. This also does not appear in my VS.

P.S.

1. I am using VS-2013, win 7 64-bit


2. I cannot contact the tutorial maker otherwise could have asked him directly
