Objective c OCMock-如何期望nsarray的内容

我想测试我在数据库中插入的值是否发送回我的类的委托

我试图模拟委托，并期望使用用于填充数据库的数组。它失败是因为2个NSArray具有相同的内容，但是不同的对象

我尝试在我的模型上实现isequal和hash方法，但没有成功

以下是错误日志：

'OCMockObject[NewsListViewController]: unexpected method invoked: service:<RSSService-0x4c25b90-324400011.636966: 0x4c25b90> didFinishParsingRSSWithItems:(
    description102362,
    description102362,
    description102362,
    description102362,
    description102362
) 
    expected:   service:<OCMAnyConstraint: 0x4c10f30> didFinishParsingRSSWithItems:(
    description102362,
    description102362,
    description102362,
    description102362,
    description102362
)'

下面是我正在测试的方法：

- (void) loadAllArticles {
    NSArray *articles = [self articlesFromDatabase];
    [self.delegate service:self didFinishParsingRSSWithItems:articles];
}

谢谢你的帮助，

这两个数组是否可能具有相同的内容但不同的地址？可能尝试与

isEqualToArray

[[mockDelegate expect] service:[OCMArg any]
  didFinishParsingRSSWithItems:[OCMArg checkWithSelector:@selector(isEqualToArray:)
                                                onObject:expectedArray]]

快！它提供了一组匹配器，这些匹配器与OCMock一起工作，可以进行更干净的测试。以下是您的期望：

[[mockDelegate expect] service:[OCMArg any] didFinishParsingRSSWithItems:contains(article1, article2, article3, article4, article5, nil)];
// or, if order is unpredictable
[[mockDelegate expect] service:[OCMArg any] didFinishParsingRSSWithItems:containsInAnyOrder(article1, article2, article3, article4, article5, nil)];

如果出于某种原因确实不想使用hamcrest，可以在测试类中创建一个方法来评估articles数组。但我觉得有点难看：

- (void) testServiceShouldNotLoadArticlesFromRSSFeedIfArticlesInDatabase {
    NSArray *fakeArticles = [TestUtils createArticles:5];
    [[DatabaseManager sharedManager] saveArticles:fakeArticles];

    RSSService *mockService = [OCMockObject partialMockForObject:service];
    id mockDelegate = [OCMockObject mockForClass:NewsListViewController.class];
    [[[mockDelegate stub] andCall:@selector(service:verifyFiveArticles:) onObject:self] service:[OCMArg any] didFinishParsingRSSWithItems:[OCMArg any]];
    mockService.delegate = mockDelegate;

    [mockService loadAllArticles];
    [mockService verify];
    [mockDelegate verify];
}

-(void)service:(id)service verifyFiveArticles:(NSArray *)articles {
    STAssertEquals(5, [articles count]);
}

它应该做什么？我在构建时收到一条警告：“警告：语义问题：不兼容的指针类型将“id*”发送到类型为“NSArray*”的参数，并在运行时发生崩溃：原因：'-[\uu NSArrayM pointerValue]：未识别的选择器发送到实例0x6242960'我更新了答案-改为尝试此方法。第一篇文章肯定不正确，它应该做什么？我在构建时收到一条警告：“警告：语义问题：不兼容的指针类型将“id*”发送到类型为“NSArray*”的参数，并在运行时发生崩溃：原因：'-[\uu NSArrayM pointerValue]：未识别的选择器发送到实例0x6242960'我更新了答案-改为尝试此方法。第一篇帖子绝对不正确。
