NBehave Notes

20 May 2010 08:55

We’ve just started using NBehave, so this is a random selection of notes:

If you try to use NBehave-Console with a .NET 4.0-compiled assembly, you’ll see a BadImageFormatException. You can fix this by creating the NBehave-Console.exe.config file, as follows:

<?xml version="1.0" encoding="utf-8" ?>
    <supportedRuntime version="v4.0.30319"/>

This makes it use the v4.0 CLR. See this question on StackOverflow.

NBehave’s command-line parsing is a bit flakey. If you pass /scenarioFile (rather than /scenarioFiles), the invalid switch is ignored; no error is raised.

Similarly, it ignores unrecognised lines in the text scenario files, so make sure that you type “When”, “Given”, etc., correctly.

Also, NBehave-Console.exe is compiled for “Any CPU”, so if you’re testing stuff that requires 32-bit DLLs (e.g. COM components), you’ll need to use CORFLAGS /32BIT+ to fix up the EXE.
