将原语传递给 OCMock 的存根 [英] Passing primitives to an OCMock's stub

问题描述

我正在学习如何使用 OCMock 来测试我的 iPhone 项目，我有这个场景:一个 HeightMap 类使用 getHeightAtX:andY: 方法，以及一个 Render 类使用 HeightMap.我正在尝试使用一些 HeightMap 模拟对 Render 进行单元测试.这有效:

I'm learning how to use OCMock to test my iPhone's project and I have this scenario: a HeightMap class with a getHeightAtX:andY: method, and a Render class using HeightMap. I'm trying to unit test Render using some HeightMap mocks. This works:

id mock = [OCMockObject mockForClass:[Chunk class]];
int h = 0;
[[[mock stub] andReturnValue:OCMOCK_VALUE(h)] getHeightAtX:0 andY:0];

当然，仅适用于 x=0 和 y=0.我想使用平面"高度图进行测试.这意味着我需要做这样的事情:

Of course, works only for x=0 and y=0. I want to test using a "flat" height map. This means I need to do something like this:

id chunk = [OCMockObject mockForClass:[Chunk class]];
int h = 0;
[[[chunk stub] andReturnValue:OCMOCK_VALUE(h)] getHeightAtX:[OCMArg any] andY:[OCMArg any]];

但这会引发两个编译警告:

But this raises two compilation warnings:

警告:传递 'getHeightAtX:andY:' 的参数 1 从指针生成整数，无需强制转换

warning: passing argument 1 of 'getHeightAtX:andY:' makes integer from pointer without a cast

和运行时错误:

调用了意外的方法:'getHeightAtX:0 andY:0 stubbed: getHeightAtX:15545040 andY:15545024'

我错过了什么?我发现无法将 anyValue 传递给这个模拟.

What am I missing? I found no way to pass a anyValue to this mock.

推荐答案

OCMock 目前不支持原始参数的松散匹配.在 OCMock 论坛上讨论了支持此的潜在更改，虽然它似乎停滞不前.

OCMock doesn't currently support loose matching of primitive arguments. There's a discussion about potential changes to support this on the OCMock forums, though it seems to have stalled.

我发现的唯一解决方案是以这样一种方式构建我的测试，即我知道将传入的原始值，尽管它远非理想.

The only solution I've found is to structure my tests in such a way that I know the primitive values that will be passed in, though it's far from ideal.
