title: I created NUnit tests, now how do I run them?
body: <p>I'm developing in vs2008, c#, .net 3.5. </p>
  
  <p>I downloaded NUnit 2.5 win / msi version. I have created a [TestFixture] Class containing several [Test] methods. </p>
  
  <p>How do I run the tests?</p>
  
  <p>When I run a NUnit demo solution from Ed Ames,  his test .cs files have an icon in the grey column to the left of the code (same place where breakpoints, bookmarks, etc show up.) Clicking on the icon gives me an option to run the tests. </p>
  
  <p>That icon is not showing up in my projects. Is there a property I need to set? </p>
  
  <p>Also, the documentation refers to a NUnit GUI that can be used to run the tests. A GUI doesnt seem to have downloaded in the msi version of NUnit.  Is there a separate download for the Gui?  </p>
