0 Seems that the stub method can be attached to any instance w/o the constraint, and the do block can make a count that you can check to assert it … In RSpec, a stub is a method stub, mean that it is a special method that “stands in” for the existing method or for a non-existing method. As of today, this implicitly tells rspec-mocks to stub the foo method. Mocks and stubs are not features of Test::Unit, but you can use the Mocha gem to add those facilities.. I am trying to test if in a method calling chain one of the methods ... should_receive and stub_chain. Flowdock is a collaboration tool for technical teams. ... (Kernel).to receive(:system) method_to_test end end I believe that the problem is that while the method is inherited from Kernel, is it not being called from the Kernel Class Object. Ruby RSpec. It supports the same fluent interface for setting constraints and configuring responses.. In the previous examples we've use the RSpec feature and_return to indicate what our stub should return when it's called. In case of stubs we allow object to receive a message, in case of mocks we expect them to receive it. That's kinda OK, but it requires me to carefully remember adding the and_call_original method. coupling). Let's say now that under the opt-in setting, any of these two would be acceptable/recommended: The difference is in the anything. If @justinko introduces a separate gem for should_receive_chain, I'd probably want to move stub_chain to that gem as well. Nothing else. Nearly all strategies for testing automation depend on some fundamentalconcepts. I don't think you can say "Running the original defeats the point of using a stub in the first place" without acknowledging that that's only one approach. In other words, tests using should_receive. In older versions of RSpec, the above method stubs would be defined like this − student1.stub(:name).and_return('John Smith') student2.stub(:name).and_return('Jill Smith') Let’s take the above code and replace the two allow() lines with the old RSpec syntax − Note that I'm not saying that every use of stub_chain is incorrect, or un-pragmatic. Feature bloat is seen in a negative light, and it's expanding functionality that exists but is not recommended, in the same way we don't expand any_instance functionality as it too is not recommend. should_receive is the old way to expect messages but carries the If tests are too hard to write, you won't write them. person = double (" person ") Person. Successfully merging a pull request may close this issue. If you need to reference your test subject you should explicitly name it using subject(:your_subject_name) { … }. @controller.template.stub! You should avoid using this method if possible, as it may be removed or be changed in the future. including in rspec-mocks for these reasons. See the should_not gem for a way to enforce this in RSpec and the should_clean gem for a way to clean up existing RSpec examples that begin with 'should.' require 'rubygems' require 'spec' class Foo def self.foo Bar.bar Bar.bar end end class Bar def self.bar end end describe 'Checking call counts for a stubbed method' do before do Bar.stub! (:start). was delegating to RSpec::Mocks::ExampleMethods#stub (which declares a test double) when called with an implicit … I add rspec to my Gemfile, not rspec-mocks, which existence one could only guess by peeking at the Gemfile.lock. Have a question about this project? Make expect(my_object).to receive(:foo) optionally illegal. So, 90% of the times what I end up writing is: expect(my_object).to receive(:foo).and_call_original. I am using RSpec 2. ... and is ambiguous when used with receive counts. The section of code we are looking at is the main game loop for Conway's Game of Life.
