check mark. Tests that are ignored
   are marked with a yellow circle, containing a question mark. If any
   tests had failed, they would be marked red, with an X symbol.</p>

<p>In this example, there were a total of 11 test cases, but one of them was not
   counted because it was marked Explicit. Note that it is shown as a gray
   circle in the tree. Of the remaining 10 tests, 5 were run successfully and
   5 were ignored.</p>

<p>The symbols shown in the tree are actually files in the NUnit bin directory
