Test Unit error when running rake tasks

Question

I upgrade my app from rails2 to rails3. Now every time I run a task I get this error:

I don't know why is loading something about Test Unit if I'm using Rspec. I tried change rake version, changing the require 'rails/all' but none fixed this issue.

But my tasks are loaded, so seems this is kind of a warning. But I'd to know how to fix this.

Update 1

These errors only appear when my task interact with Model/Controllers.

My Rakefile:

require File.expand_path('../config/application', __FILE__)
require 'rake'

CIMM::Application.load_tasks

Answer 1

Check your Rakefile. it probably loading TestUnit

You should show the custom task if you want more help.
