You are not expected to use FitNesse. In case you still want to do so, here are the necessary steps:
pl.profitfrom the repository
fitnesse.xmlin the project
mosa.typeflow.testand choosing “Run as Ant Build”.
The downside of FitNesse is that it is an additional approach to writing tests.
My (dsp's) vision would be that we could write pages like our error pages with some code snippets and directly turn them into tests.
