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. If we remove this line from code: I think one could look at the bigger picture: rspec, as a framework, currently is not capable to prevent certain type of programmer mistakes for one feature it officially offers. When an object receives a message, it invokes a method with the same name as the message. Your method suddenly returns nil. same fluent interface for setting constraints and configuring responses. ...

A should_receive expectation has to be set before you call the method under test; you're setting it afterwards. No documentation. 6. Your test has a let for user, which means the first time you mention user in your tests it will create a user. RSpec provides no special mechanisms to access elements under test, so yes, you would need to somehow stub the id method and have it return whatever you wish (e.g. with foo and return true. Simple stub. How can I stub find_each for rspec testing in rails 3 The section of code we are looking at is the main game loop for Conway's Game of Life. Trouble in RSpec test - saving parent record twice. If you stub a method or set expectations with should_receive these stubbed methods may also yield blocks. We tell RSpec that we're expecting that call to result in the String "hello". It's true that @vemv is the first to request this feature, but I've heard from multiple users over the years that were surprised by the fact that expect(my_object).to receive(:foo) prevents the original my_object.foo logic from executing when the message is received, so a change to make it less confusing is not out of the question. including in rspec-mocks for these reasons. (Edouard Chin, #2215); Fix Mocha mocking support with should . with ("/") If you change your HTTP library, even if both libraries are based on Net::HTTP and behaviour of the application won’t change, you still need to fix all your tests where you stubbed methods specific to HTTP library. execute end def execute 'foo' end end describe MyClass do it 'should stub instance method' do obj = MyClass. ruby-on-rails - value - rspec should receive multiple times with different arguments ... To simplify the testing of Family.location, I want to stub Member.location. If we want to use a Test Double as a mock or as a stub, RSpec leaves that up to us and doesn’t care. rspec-mocks is a test-double framework for rspec with ... You can use receive_message_chain in place of receive to stub a chain of messages ... which makes it quite painless to violate the Law of Demeter in violent ways, so you should consider any use of receive_message_chain a code smell. any_instance. We could support a config option like @JonRowe suggested, although that definitely adds to the future maintenance burden for maintainers of this library. ... 'spec_helper' class MyClass def self. We expect it to receive valid? I'm attempting to explain that its not what a stub is for, sure, it's entirely acceptable to test in a different fashion, checking that messages are sent regardless of their implementation, but this is a mocking and stubbing library, and thus it's point is to stub, (or fake out) a method definitions, or to replace with a mock (or double). How could I solve this? What is RSpec Stubs? It's also considered kind of a test smell to use and_call_original as it's generally better to isolate collaborators in unit tests not just assert they're called. We’ll occasionally send you account related emails. Warning: Chains can be arbitrarily long, which makes it quite painless to violate the Law of Demeter in violent ways, so you should consider any use of receive_message_chain a code smell.

Well, for many years I've (occasionally) suffered this issue without realising that a better API could have prevented all the lost time / frustration. Fast. Mock – an object that is given a specification of the messages that it must receive (or not receive) during the test if the test is to pass. How to say “should_receive” more times in RSpec Rspec, Rails: how to test private methods of controllers? The downside Stubbing and mocking are powerful techniques that can improve the speed of your test cases, isolate your code, simplify … Similarly, you can use should_not_receive to set a negative message expectation. should_receive is the old way to expect messages but carries the baggage of a global monkey patch on all objects. Something like: Would be an acceptable expansion, and if you'd like to work on it feel free. 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. 991.

For this case, we created our basic object (double) and then we set an expectation. One thing to note is that, RSpec’s syntax has changed a bit over the years. Flowdock is a collaboration tool for technical teams. If tests are too hard to write, you won't write them.

Later, we released the hide_const feature and decided that the term "mutator" was a better term to wrap up the concept of both stubbing and hiding. I add rspec to my Gemfile, not rspec-mocks, which existence one could only guess by peeking at the Gemfile.lock.

By clicking “Sign up for GitHub”, you agree to our terms of service and I am trying to test if in a method calling chain one of the methods ... should_receive and stub_chain. I don't like the idea of explicit return values, but what about a config option to run the original by default (when one is available)? This RSpec style guide outlines the recommended best practices for real-world programmers to write code that can be maintained by other real-world programmers. 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.' Once a year or so I will lose a couple hours debugging why a method suddenly starts returning nil. Using Rspec should_receive to test that a controller calls a method on an object correctly. Let's say now that under the opt-in setting, any of these two would be acceptable/recommended: The difference is in the anything.
