I don't think it's related to rspec. Note that the top of the error stack says:
#{RAILS_ROOT}/vendor/rails/actionpack/lib/action_controller/routing.rb:1273:in
`raise_named_route_error'
So the error is likely related to this bit:
actor_path(@customer,@project)
Given the nesting that you're doing multi-level nesting (which is not
recommended btw - read
http://weblog.jamisbuck.org/2007/2/5/nesting-resources), I believe
that the path should be either:
customer_project_actor_path(@customer, @project, @actor)
or
customer_project_actors_path(@customer, @project)
