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:
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?
