Sorry, before I wrote with errors the example (it's the problem if you
are remember without code at your face). This is the correct example
with the suggestions to fix the problem:
#foo.rb
class Foo < ActiveRecord::Base
has_one :bar
def foo
self.bar.count -= 1
end
end
#foo_spec.rb
require File.expand_path(File.dirname(__FILE__) + '/../spec_helper')
describe Foo do
before(:each) do
@bar = stub_model(Bar, :count => 1)
@foo = Foo.new(:bar => @bar)
@before_value = @foo.bar
end
it "should decrement bar.count in 1" do
@foo.foo
@foo.bar.count.should be_equal(@value_before - 1)
end
end
#bar.rb
class Bar < ActiveRecord::Base
end
And now, I got this error:
1)
NoMethodError in 'Foo should decrement bar.count in 1'
undefined method `count=' for #<Bar id: 1001, created_at: nil,
updated_at: nil>
/home/carlos/NetBeansProjects/RailsApplication1/app/models/foo.rb:5:in
`foo'
/home/carlos/NetBeansProjects/RailsApplication1/spec/models/foo_spec.rb:11:
What it's wrong? Can I make this type of test with mock or stub?
