There are two ways I would try to go on this. One would be to add the
aliases to the actual association:
it “should trigger mark_as_deleted in related aliases” do
3.times do |i|
alias = mock(“alias #{i}”)
alias.should_receive(:mark_as_deleted)
@person.aliases << alias
end
@person.destroy
end
The other would be to stub owner_quoted_id on the array:
it “should trigger mark_as_deleted in related aliases” do
aliases = []
aliases.stub(:owner_quoted_id)
3.times do |i|
alias = mock(“alias #{i}”)
alias.should_receive(:mark_as_deleted)
aliases << alias
end
@person.stub!(:aliases).and_return(aliases)
@person.destroy
end
I'm not sure that either would work :) But that's where I'd start.
HTH,
David
