Xcode 6, Swift and mock verification without exceptions

问题

Anyone know how to verify an OCMock expect in Swift? Swift Doesn't use Exceptions so XCTest no longer includes XCTAssertNoThrow. Is There any other way to verify a method was called with OCMock? I noticed in OCMock the verify function checks the expectations array so I assume we could do XCTAssertTrue(mock.expectations == 0) if we had access.

Trying to figure some of these more complicated things out since there is little to no docs around XCTests in Swift

Ok so Not a real answer but a work around for ObjC / Swift Projects. Write an Object Wrapper that will run [mock verify] and return a bool.

Create an Obj-c H and M file. In the .h

+ (BOOL)verifyMock:(id)mock;

In the .m

+ (BOOL)verifyMock:(id)mock
{
    BOOL called = YES;
    @try {
        [mock verify];
    }
    @catch (NSException *exception) {
        called = NO;
    }
    @finally {
        return called;
    }
    return called;
}

Now add this Obj-c file to your Bridging-Header file so swift has access.

In your Swift XCTest file

XCTAssertTrue(YourWrapperClassName.verifyMock(mock), "Method was not called")
