Objective c OCMock模拟协议'；s的静态类方法。

OCMock 3中的新功能是模拟

可以模拟协议中定义的类方法吗？i、 e

@protocol AViewControllerProtocol <NSObject>
+ (Type)typeForViewController;
@end

异常抛出

NSInvalidArgumentException:无法存根/预期/验证方法“typeForViewController”，因为模拟类中不存在此类方法

这看起来像是OCMock 3.1中的一个疏忽，但是如果您愿意，您可以自己进行修复

// OCProtocolMockObject.m
- (NSMethodSignature *)methodSignatureForSelector:(SEL)aSelector
{
    struct objc_method_description methodDescription = protocol_getMethodDescription(mockedProtocol, aSelector, YES, YES);
    if(methodDescription.name == NULL) 
    {
        methodDescription = protocol_getMethodDescription(mockedProtocol, aSelector, NO, YES);
    }
    // Add this case for required class methods
    if (methodDescription.name == NULL)
    {
        methodDescription = protocol_getMethodDescription(mockedProtocol, aSelector, YES, NO);
    }
    // Add this case for optional class methods
    if (methodDescription.name == NULL)
    {
        methodDescription = protocol_getMethodDescription(mockedProtocol, aSelector, NO, NO);
    }
    if(methodDescription.name == NULL)
    {
        return nil;
    }
    return [NSMethodSignature signatureWithObjCTypes:methodDescription.types];
}

我通过此测试验证了此修复：

- (void)testProtocolClassMethod {
    id mockedViewController = OCMProtocolMock(@protocol(AViewControllerProtocol));

    // FIXED: This line compiles fine, but throws an exception at run time.
    OCMStub([mockedViewController typeForViewController]).andReturn(SomeType);

    Type type = [mockedViewController typeForViewController];

    XCTAssertEqual(type, SomeType, @"Not equal!");

    OCMVerify([mockedViewController typeForViewController]);
}

我会在项目页面上对此提出请求。

我还没有时间回顾这个答案，但看起来很不错，谢谢。做得好。使用OCMock 2.2.4时也有同样的问题。我刚刚向master发布了一个修复程序。

- (void)testProtocolClassMethod {
    id mockedViewController = OCMProtocolMock(@protocol(AViewControllerProtocol));

    // FIXED: This line compiles fine, but throws an exception at run time.
    OCMStub([mockedViewController typeForViewController]).andReturn(SomeType);

    Type type = [mockedViewController typeForViewController];

    XCTAssertEqual(type, SomeType, @"Not equal!");

    OCMVerify([mockedViewController typeForViewController]);
}
