Hey there guys,
not sure where I should discuss this really,
but I've created a ticket on LightHouse for rSpec.

Came across this problem;

"I have a method which either returns an array or a nil, how can I rspec
assert this?"

solution could be

[NilClass, Array].should include(Model.get_array_or_nil)

but that's rubbish.
I want;

Model.get_array_or_nil.should
either(be_an_instance_of(Array)).or(be_nil)

http://rspec.lighthouseapp.com/proje...her-or-matcher
should provide that.
(although it's built against the old svn repo, need to update it for
GIT)

Any thoughts?

MatthewRudy

Agreed. You should specify the different conditions under which the
method returns nil or an array in distinct examples. For example,
Array#reject! behaves this way. I'd write some examples like:

describe Array, "#reject!" do
before(:each) do
@letters = %w[b c d]
end

it "returns nil if no changes were made" do
@letters.reject! { |letter| letter < 'b' }.should be_nil
end

it "returns an array of values remaining after ones matching the
given criteria are rejected" do
@letters.reject! { |letter| letter > 'b' }.should == ['b']
end
end

By the way, the RSpec lists [ http://rubyforge.org/mail/?group_id=797
] would be a good place to discuss custom matchers.

Regards,
Craig

cheers Craig,
I have a feeling I don't do anything in any standard style.

will check out the mailing list,
unfortunately it's not tracked by ruby-forum.com, which is where I do
all my ruby discussion stuff
