title: F# development and unit testing?
body: <p>I just got started with F#, which is my first functional language. I have been working quasi-exclusively with C#, and enjoy a lot how F# leads me to re-think how I write code. One aspect I find a bit disorienting is the change in the process of writing code. I have been using TDD for years in C# now, and really appreciate to have unit tests to know where I am at.</p>
  
  <p>So far, my process with F# has been to write some functions, play with them with the interactive console until I am "reasonably" sure they work, and tweak &amp; combine. This works well on small-scale problems like the Euler Project, but I can't imagine building something large that way.</p>
  
  <p>How do people approach unit testing and building a test suite for a F# program? Is there an equivalent to TDD? Any pointers or thoughts are appreciated.</p>
