I've figured out how to run my tests from the commandline using:
java -jar fitnesse.jar -c MyFixturePage?test&format=text -d "c:/utils/fitnesse/" -r "FitNesseRoot"
Using this as the startup parameters for my Fixture assembly project in visual studio does not work. I'm using the Slim runner and executor in my fixtures : http://github.com/jediwhale/fitsharp/downloads
Has any one worked out how to get debugging with Slim working in Visual Studio?
