In doing some research I found that it is possible to do Rails type BDD/testing in WPF using IronRuby.  I am very excited about this and will be doing an in-depth post on this in the very near future.  But, for now I wanted to get a post out on how to get Cucumber up and running in IronRuby because in attempting to do this myself I ran into an issue that turns out is fairly well-known but as far as I can tell is not documented.  I would like to thank Nathaniel Ritmeyer, aka NatOnTesting, for helping me through this and take a look at his Bewildr gem…it will be a key piece of my future post.

Here are the steps for getting Cucumber up and running with IronRuby:

1. Install Ruby (to save headaches install to c:\ruby and make sure “c:\ruby\bin” is in your Path environment variable)
2. Install IronRuby (to save headaches install to c:\ironruby and make sure “c:\ironruby\bin” is in your Path environment variable)
3. Install Cucumber (here is the undocumented part…until now)
   1. Because Gherkin is required by Cucumber version > 0.6.3 and Gherkin is not compatible with IronRuby we need to install Cucumber version <= 0.6.3.
   2. 
4. Next you need to create a Cucumber wrapper script for IronRuby
   1. Go to c:\ruby\bin
   2. Create a blank text file “icucumber.bat”
   3. Open icucumber.bat in text editor
   4. Enter this text

      1. @ECHO OFF
         SET GEM_PATH=c:\ruby\lib\ruby\gems\1.9.1
         @"C:\IronRuby\bin\ir.exe" "c:\Ruby\bin\cucumber" %*

   5. Save the file
5. Test it (results are truncated)

   

That’s it.  You now have Cucumber running with IronRuby.  Why is this helpful?  Stay Tuned!
