title: Using Mocks to Substitute Word Doc in C#
body: <p>can some one please provide an example of how would one go about
  swapping out a Word document wit Mocks object (for testing scenario). My application uses Word document for populating template fields (in the doc) and also reading values from those fields as well, so it would be great to see an example of how to do that</p>
  
  <p>Thanks,
  Alex</p>
