title: NUnit data driven unit test with datasource
body: <p>I have one data source like -4,-3,-3,-2,-1,0,1,2,2,3,4 , I have one function and this function can capture repeated number for example in this data source we have -3,2 are repeated .The repeated numbers are reported in end of the program.
  I couldn't find good example(I spent 3 hours).
  How can I implement a unit test with NUnit that can be test the same situation and it tells me the results, if you have some example , It will be very useful to me.(Really appreciated).</p>
