David,
I set an instance variable @dut (domain under test) in a before block in
the spec and use it in the macro. I don't know if this is the best way but
I'm not an expert Ruby programmer.
before(:each) do
@event_group = Factory.build(:event_group)
@dut = @event_group
end
## and an example call in the spec
it_should_require_attributes :name, :created_by
Here are just a few methods from the macro .....
module ModelMacros
## dut - Domain Under Test
## aut - Attribute Under Test
def it_should_require_attributes(*attrs)
attrs.each { |attr| it_should_require_attribute(attr) }
end
def it_should_not_require_attributes(*attrs)
attrs.each { |attr| it_should_not_require_attribute(attr) }
end
def it_should_require_attribute(aut)
it "is not valid with missing #{aut}" do
@dut.send("#{aut}=", nil)
@dut.should_not be_valid
@dut.should have(1).error_on(aut.to_sym)
end
end
def it_should_not_require_attribute(aut)
it "is valid with missing #{aut}" do
@dut.send("#{aut}=", nil)
@dut.should be_valid
end
end
end
I hope this helps. I'm really racking my brains but I just can't think of
anything.
