I’m new to RSpec so excuse me if I’m missing something obvious here. I
recently renamed an attribute on a model, and my generated view spec
didn’t
detect it. This resulted in a defect going through undetected. Even
worse,
I’m not sure how I could reasonably get RSpec to detect such a change.
I suspect the problem isn’t specific to RSpec, but I encountered it
whilst
dealing with RSpec and thought this would be a good place to ask for
advice.
The details:
I used RSpec to generate scaffolding for a model we’ll call ‘Resource’.
Resource has an attribute called ‘entity’.
It generated for me a view for a Resource - including its ‘entity’
attribute. It also generated a corresponding spec that looked like this:
describe “/resources/index.html.erb” do
include ResourcesHelper
before(:each) do
resource_98 = mock_model(Resource)
resource_98.should_receive(:entity).and_return(“MyString”)
…
end
it “should render list of resources” do
render “/resources/index.html.erb”
response.should have_tag(“tr>td”, “MyString”, 2)
…
end
end
It also generated a fixture and model spec, which I tweaked as follows:
describe Resource do
fixtures :resources
it “should have an entity” do
resources(:one).entity.should == ‘MyString’
end
end
Both specs pass. Excuse the lame model spec - I’m about to get to the
point.
Next I decided I wanted to rename the ‘entity’ attribute to ‘entities’.
My
model spec failed, so I fixed it. However, the view spec didn’t fail. It
expected that the view would call ‘entity’ on the mock Resource - and
this
was indeed still the case.
However, when I went and actually looked at the page, it died - the
‘entity’
attribute didn’t exist anymore on the model.
I’m not sure how I could have picked that up with an automated test.
Any ideas?
Thanks,
Ben
