It's all gone a bit meta.
I've started noticing patterns in my specs, where I want more than
one class to satisfy a specific bunch of behaviours.
I know I can use it_should_behave_like and this works in simple
cases, but I want to be able to iterate around an array of values and
generate a my bunch of it "should ..." specs for each item in the array.
I know I can do this by going
describe "the cheese factory"
[:cheddar, :brie, :lancashire].each do |cheese|
it "should create a valid piece of #{cheese}" do
Factory.create(cheese).should be_valid
end
it "should create a piece of #{cheese} with valid packaging" do
... etc
end
end
...but what if I want to specify other factories too, all of which
conform to the it blocks I specified above? (e.g. a ToyFactory that
creates valid toys with valid packaging). How can I factor that spec
logic out?
I tried putting the content of the (do |cheese|) block into a method,
but ruby doesn't seem to be able to see that method when the describe
block runs... I guess I need to maybe patch it into some RSpec class
instead? Or put it into a module and include it? Am I going down the
wrong lines? is there an easier way to achieve this?
Sorry if this is a dumb question, I'm bumping up against the
limitations of my ruby experience again :)
cheers,
Matt
