如何在OCMock中模拟接受句柄作为参数的方法? [英] How do i mock a method that accepts a handle as an argument in OCMock?

问题描述

我正在尝试模拟一种等效于以下签名的方法:

I'm trying to mock a method that has the equivalent of the following signature:

- (NSDictionary *) uploadValues:(BOOL)doSomething error:(NSError **)error

我希望它返回一个小的字典，以便我的测试可以确保代码正确使用了字典.但是，无论我做什么，OCMock始终从该方法返回nil，无论我如何将其存根.错误开始于我正在测试的代码中的nil，这些是我尝试对其进行存根的不同方式:

I want it to return a small dictionary so that my test can make sure the code uses the dictionary properly. however, no matter what i do OCMock always returns nil from the method, regardless of how i stub it out. The error begins as nil in the code i'm testing, and these are the different ways i've tried stubbing it:

NSError * error = nil;
[[[mock stub] andReturn:someDict] uploadValues:YES error:&error];

[[[mock stub] andReturn:someDict] uploadValues:YES error:nil];

[[[mock stub] andReturn:someDict] uploadValues:YES error:[OCMArg any]];

，它们都不起作用. OCMock是否支持将消息参数作为存根处理?如果是的话，正确的处理方法是什么?

and none of them work. Does OCMock support handles as stubbed message arguments and if so, what's the correct way to do it?

推荐答案

遗憾的是，我也没有找到一个好的解决方案.我能说的最好的办法是尝试尽可能少地使用NSError **，然后将其放在一个隔离的函数中，您可以在部分模拟中完全模拟掉.

Sadly, I haven't found a good solution for this either. The best I can say is to try to make the use of the NSError** as small as possible, and then put it in an isolated function that you can completely mock out on your partial mock.

我发现，使用除NSObject *(或派生的)或原始值(NSInteger，BOOL等)之外的任何代码的代码几乎不可能使用OCMock进行测试.

I'm finding that any code that uses anything other than an NSObject* (or derived) or primitive values (NSInteger, BOOL, etc) is pretty much impossible to test using OCMock.
