I have some finders in my models where I write some of the sql myself. I
of course want to test these, but am not sure the best way. Should I
just
let them roll through to the db, and verify they return the correct
objects based on the fixtures I load, or should I spec the actual query?
I
know that DB access is sort of frowned upon, but is this a situation
where
it is more or less acceptable? My spec looks something like this, but
just
feels funny because I’m essentially rewriting the query.
describe User, ‘when calling find_by_username’ do
before(:each) do
User.stub!(:find).and_return(nil)
end
it ‘should convert the username to lowercase’ do
uname = ‘Joe’
uname.should_receive(:downcase).and_return(‘joe’)
User.find_by_username(uname)
end
it ‘should call find with custom options’ do
User.should_receive(:find) do |a, b|
a.should == :first
b[:conditions][0].should == “lower(username) = :username”
b[:conditions][1][:username].should == ‘joe’
end
User.find_by_username(‘Joe’)
end
end
