If you see this error message:

undefined method `use\_transactional\_fixtures=’ for  
Test::Unit::TestCase:Class (NoMethodError)

You should check all your dependencies, all the lines containing  
require and especially require\_dependency.

You have probably done a refactoring “Rename” a class and forgot to  
propagate the change everywhere!

The solution that worked for me is to remove “test” from the  
require\_paths line in:

/usr/local/lib/ruby/gems/1.8/specifications/ZenTest-3.4.2.gemspec  
(your path may vary)

s.require\_paths = [“lib”,“test”]  
becomes  
s.require\_paths = [“lib”]

I installed a gem recently that also updated hoe and ZenTest, which is  
right when the problem started. I assume the next release of one of  
these gems will correct the issue. I found this solution at  
[http://rubyforge.org/tracker/index.php?func=detail&aid=6241&group\_id=419&atid=1678](http://rubyforge.org/tracker/index.php?func=detail&aid=6241&group_id=419&atid=1678)

Hope it saves someone a headache.
