Testing for anonymous function in toBeCalledWith

[Ben Loveridge]

Hi,

In one of my functions, I am invoking an async API which expects a few
parameters, with the last one being a callback function. Due to some
variables that need to be available in the callback function, I am
using an anonymous function as the callback so the callback has scope
reference to those variables.

When testing this function, I am trying to verify that the
asynchronous API is called with the correct parameters -- since the
callback provided is an anonymous function, I can't seem to do it.

expect(the.function).toHaveBeenCalledWith(a, b, c); // doesnt work,
because the 4th parameter was a function which we didn't tell Jasmine
about

Short of writing a custom matcher, is there a way to expect a
parameter to just be anything of a given type? Something like this
comes to mind:

expect(the.function).toHaveBeenCalledWith(a, b, c,
jasmine.typeof("function"));

Thanks in advance for any help or guidance.

Look into jasmine.any()

You should be able to

expect(the.function).toHaveBeenCalledWith(a, b, c, jasmine.any(Function));

Thanks!

Awesome, that's exactly what I was looking for -- can't believe I
missed that in the JSDoc.

Thanks, and thanks for the fast reply!

And, thanks for not just responding with "RTFM" -- I do feel quite
sheepish though *blush*

Don't ever feel bad about that -- there's lots of room for improvement in our docs. Plenty of patterns some of us use are not well-documented. We'll get there one day. ;) 

Thanks!
