More intuitive expectations on blocks

[dmeehan1968]

I was wondering if anyone had a pattern they used, or if Kiwi has something I'm unaware of, for neatly solving the expectation that a block should be invoked.

I've seen the following pattern suggested for verifying whether a block is called on success, but this seems a bit verbose and unintuitive.

__block BOOL isValid = NO;

[sut doSomethingWithValue: aValue success:^{
    isValid = YES;
}];

[[theValue(isValid) should] beYes];

A bit of playing suggests that block pointers are recognised as Objective-C classes, although not descended from NSObject, which Kiwi expectations need to be applied to.

I was wondering is something like the following might be possible/desirable?

void(^block)(void) = ^{};

[[block should] invoke];

[sut doSomethingWithValue:aValue success:block];

The idea being that you should be able to do variations on:

[[block should] invoke];
[[block shouldNot] invoke];
[[block shouldEventually] invoke];

etc.

Any thoughts?

It would definitely be a nice matcher. I don't know how to actually tell whether a block has been executed, though.

Interesting thoughts.. might take a look into this one

👍 a way to check if a block was invoked would be awesome
