[rspec-users] strange error on mock proxy

Brandon Keepers Fri, 07 Dec 2007 08:44:03 -0800

I'm banging my head over this really strange error in a view test when I run "rake spec". The weird thing is that I don't get the error when I run the spec file by itself.


Here is the spec (I know, fixtures are the devil):


describe "/units/new.html.erb here" do
  fixtures :units, :accounts, :groups
  it_should_behave_like '/units/_form'

  before do
    login_as :cathy
    assigns[:unit] = @unit = Unit.new
    @groups = accounts(:dawson).groups
    render "/units/new.html"
  end

  it "should render new form" do
    response.should have_tag("form[action=?][method=post]", units_path)
  end

end

And the error:

4)

ActionView::TemplateError in 'Spec::Rails::Example::ViewExampleGroup/ units/new.html.erb should render new form'

You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.include?
On line #13 of units/_form.html.erb

I'm not sure why the error is in the mock proxy because this spec isn't using mocking at all.


Any ideas?
