RSpec can't find and_callback matcher? #1

Open alassek opened 7 years ago

alassek commented 7 years ago

Am I missing something obvious here?

I've added gem 'rspec-hollerback-mocks' to my Gemfile test group, and added require 'rspec/hollerback/mocks' to my spec_helper.rb.

Writing an expectation like this:

expect_any_instance_of(MyClass).to receive(:method).and_callback(:foo, value)

results in an error:

undefined method `and_callback' for #<RSpec::Mocks::AnyInstance::PositiveExpectationChain:0x007fccc9de8d28>

Ruby: 2.3.3 Rails: 5.0.0.1 RSpec: 3.5.0

Thanks for the report! Is there any relevant stack trace you can provide?

@delner more detail for you. It seems that

expect(myclass_instance).to receive(:method).and_callback(:foo, value)

works as intended. So the problem lies specifically with expect_any_instance_of and allow_any_instance_of.

delner commented 7 years ago

Ah, that might make sense. I may not have implemented expect_any_instance_of and allow_any_instance_of. I'll make some plans to add support for this, if possible.
