Though it was in the test/unit module for 1.8, 1.9’s minitest module  
seems to lack an assert\_nothing\_raised method. That is kind of  
frustrating. I’ll give 10 thank-yous to the first person who knows how  
to write a minitest compatible test for what in Test::Unit looked  
like:

def test\_no\_error\_is\_raised  
assert\_nothing\_raised do  
method\_whatever(\*args)  
end  
end

Thanks (that one is free),  
Tim

It was removed because it’s not useful enough. Test the proper behavior  
of your method, not the fact that it doesn’t raise an exception.
