This is very surprising behavior considering it used to work and this is a very common use case. Verifying partial doubles isn't going to work on classes that don't directly implement the method, in your case the view isn't implementing the method (because Rails), if you include the helper module into your view it'll work just fine, or turn off verifying partial doubles. Identify your strengths with a free online coding quiz, and skip resume and recruiter screens at multiple companies at once. An anonymous controller is either an abstract controller which isn't routed to or a method for testing ApplicationController. I will need to look into it later. Successfully merging a pull request may close this issue. Again you need to include the helper module into your view (which is isolated from the controller at that point so we don't know which ones to include for you) or turn off verifying partial doubles. When you are writing a test case for codes which involve time sensitive functionality, you often encounter the need to create multiple test objects with different date and time attributes in order … Working with Dates and Times in Rails RSpec testing Read More » 2. If you are to automate a test, your test cases should return the same results every time so you can verify those results. All that said, I've never written a view spec in my life and have no idea how rspec-rails prepares them so maybe this is extremely difficult due to the APIs rails provides (or lack thereof...). The main difference is in the type of assertions that we made, rather than the tool we used. let is lazily executed, meaning its executed only when called. If there are any side effects from that call, the test outcome could be affected. The difference being that this is "broken" due to verifying partial doubles, methods which exist on controllers should be stub-able with partial verification turned on, where as #1219 is creating stubs for things that don't exist. If not, can you provide a summary of the work that was agreed to be done? We use RSpec feature and specs heavily, controller and view specs more judiciously, FactoryGirl for test data, JavaScript integration specs with Poltergeist or Capybara Webkit, like test doubles and test spies but not test mocks, and we stub external requests with Webmock. In this configuration I failed to stub method on view: it fails with #<#:0x000001059b9f00 ... > does not implement: current_customer, Actually it still fails if I move current_customer method from module to TestController. Seems like we could change how the view and helper objects are created (to more closely mirror how rails does it....and/or leverage how rails does it somehow) w/o running the controller filters and actions. It's simply how Ruby works and RSpec can't do anything about that. It's free, confidential, includes a free flight and hotel, along with help to study to pass interviews and negotiate a high salary! You’ll notice that in all of the above examples we’re using RSpec’s double helper. The RSpec syntax converter. Mind the order: You can even chain multiple and_yield statements to yield the block multiple times with different arguments: Does your version of Ruby on Rails still receive security updates? Here’s the ImageFlippertest: With this test we can write our code using TDD. This is handy if the returning object is receiving a block call. Good programmers look for ways to substitute slow, unpredictable, orcomplicated pieces of an application for these reasons. 3. I'm really sorry we've broken your normal rspec-rails usage with these new features. As a general principle, it's not a good idea to stub the object under test. Say I have this method, which is not on a class … Lately, a need for a small number of end-to-end tests became relevant. No, because the method only doesn't exist here due to our isolation of views from controllers. These should work on 2.14. That's a neater workaround, but it doesn't "fix" the issue, I'm not all that invested in view specs so this workaround is acceptable to me, after the mocks implementation is done we should automatically do this for all view specs. Simple. NOTE: You do not need to use rspec-dev to work on a specific RSpec repo. RSpec is warning you that you should take action to correct this. Download the RSpec software. Should view spec infer contoller name by spec name and provide right contoller? Stub controller helper method on rspec rails 3, # spec/views/orders/new.html.slim_spec.rb, 'Stub current_user if you want to test the behavior. fails with an #<#:0x007fa71c1c2d78 ...>> does not implement: current_user.

In RSpec, a stub is often called a Method Stub, it’s a special type of method that “stands in” for an existing method, or for a method that doesn’t even exist yet. This is handy if the returning object is receiving a block call. Ah OK. That makes sense, but was hard to parse out here. RSpec does not explicitly require the use of test spies to make message expectations. Repeatable.
