Hi Gabriel, So, you've stumbled across a bit of a confusing "feature" of MacRuby and interaction with Obj-C. The full method name of the Obj-C method, as Ruby sees it, is actually "buildRequestWithUrl:method:header:body:", since this is the selector. So, I think your mock should work if you simply modify it as follows: @requestBuilder.should_receive(:"buildRequestWithUrl:method:header:body:") .with("http://example.com", method: "POST", header: nil, body: anything() ) .and_return(nil) Please let us know if that doesn't work!

Hi,
I'm having some strange issue with rspec mocks and hope someone can point out what I'm doing wrong.
I have a Objective C class with the method: buildRequestWithUrl:method:header:body: I wrote an rspec mock for this class. I'm setting up an expectation as follows:
@requestBuilder.should_receive(:buildRequestWithUrl) .with("http://example.com", method:"POST", header:nil, body:anything() ) .and_return(nil)
When the class being tested calls the aforementioned method I get the following error:
RuntimeError: NSInvalidArgumentException: -[Mock buildRequestWithUrl:method:header:body:]: unrecognized selector sent to instance 0x200373ea0
I set the expectations for another method of the same class called :queryStringForDictionary In this case the expectation and call do work.
@requestBuilder.should_receive(:queryStringForDictionary).and_return( body )
In another project I'm calling the same class from ruby code and there the mocks and expectations do work properly. In this Objective C project they don't.
Thanks in advance, Gabriel Ayuso
