Testing associations in Rspec

Problem
You would like to test your model associations in an RSpec model spec, to make sure that they are correctly set up.

Solution
After some Google searching and coming across this article here, ended up using the second method described there with the reflect_on_association method, as it doesn’t need the inclusion of another gem.
So for example to to test multiple has_many or belongs_to associations in your model rspec you could use something like:
context "check associations" do
# belongs_to associations
%w{bel_to1 bel_to2}.each do |bt|
it "should belong to #{bt}" do
m = Model.reflect_on_association(:"#{bt}")
m.macro.should == :belongs_to
end
end
# has_many associations
%w{has_many1 has_many2 has_many3}.each do |hm|
it "should have many #{hm}" do
m = Model.reflect_on_association(:"#{hm}")
m.macro.should == :has_many
end
end
end

ArgumentError (3 elements of civil date are necessary)

Solution
The workaround is to use:
