I followed the steps described on the wiki to be able to run the specs  
for  
ironruby but when I then execute rake test  
I get the following output:

“rake test” is not the preferred way of running tests; directly run the  
mspec command (or use irtests.bat, see below). This will use a version  
of mspec that’s checked in, so you don’t need a separate directory for  
mspec. Doing a “where mspec” should yield:

c:\tools\ironruby\Merlin\External.LCA\_RESTRICTED\Languages\IronRuby\mspec\mspec\bin\mspec  
c:\tools\ironruby\Merlin\External.LCA\_RESTRICTED\Languages\IronRuby\mspec\mspec\bin\mspec.bat

If you run Dev.bat, this path will be set up for you, and a .mspecrc  
file copied to %HOME%, which will hook everything up properly.

To run all the tests, there’s a single script  
Merlin\Main\Languages\Ruby\Scripts\irtests.bat which should do the  
trick. We should hook this back up into rake, but I think those rake  
files are pretty scary, so we have some external scripts written by  
people who don’t want to mess with rake. =P
