Testing with blocks and yield_with_args

[Nicholas Wieland]

Hi I'm trying to test the return the value returned by a method that accepts a block, that should yield a double.

I don't know what I'm doing wrong, most probably I don't understand how to use the matched. Can someone help me out?

 `yield_with_args` expects arguments, which specify what arguments you expect to be yielded.  You passed `yield_with_args` no args.  I think you want `yield_with_args(post)`.

That said, you pasted only your code, and not the output RSpec is giving you, so I'm not quite sure what isn't working how you expect.  If there's more to it than that, please post the RSpec failure you're getting.

HTH,

Myron

Hi, I changed my spec  but still having problems, I'm not able to stub an array-like object ... Thanks for your help!

In Ruby each does not necessarily return a meaningful value (it could be nil or self for the object). You are stubbing a return value but each is used to yield to a block; which the stub does not do. Is this object actually an array? I’m a bit confused by it’s contract given your use of each and next with it.

In this situation, I generally would just suggest stubbing an array like object, I would say to just provide an array.
