The spec is very simple. This was working with rails2+rspec1.3… I’m
using rails3+rspec2 now. The error message is not very clear.

Any idea why this happens?

Hi David,

Thanks for the reply but that didn’t fix my problem.

I think this is somehow related to fixtures, at least I only get this
problem on the specs that use fixtures and if I remove the fixtures,
it works.

Ok… found the problem… had this line in my spec helper commented

config.fixture_path = “#{::Rails.root}/spec/fixtures”
