OCMock - 如何期待nsarray的內容

我想測試我在數據庫中插入的值是否發回給我的類的委託。OCMock - 如何期待nsarray的內容

我試圖模擬委託，並期望我用來填充數據庫的數組。它失敗，因爲2 NSArray具有相同的內容，但是是不同的對象。

我試過在我的模型沒有成功實現isequal和哈希方法。

以下是錯誤日誌：

'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 
)'

我怎樣才能做到這一點？

這裏是我的測試：

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

    RSSService *mockService = [OCMockObject partialMockForObject:service]; 
    id mockDelegate = [OCMockObject mockForClass:NewsListViewController.class]; 
    [[mockDelegate expect] service:[OCMArg any] didFinishParsingRSSWithItems:fakeArticles]; 
    mockService.delegate = mockDelegate; 

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

這裏是方法我測試：

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

感謝您的幫助，文森特

有沒有可能是兩個數組具有相同的內容但地址不同？也許試圖與isEqualToArray

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

它應該做什麼？我在構建時得到了一個警告：「警告：語義問題：不兼容的指針類型將'id *'發送給'NSArray *'類型的參數並導致崩潰：reason：' - [__ NSArrayM pointerValue]：發送到實例的無法識別的選擇器0x6242960' – vdaubry 2011-04-14 10:00:40

我更新了我的答案 - 試試這個。第一篇文章絕對不正確。 – AdamH 2011-04-14 12:48:16

比較獲取OCHamcrest！它提供了一堆與OCMock一起工作的匹配器，並進行更清潔的測試。這是你的期望是什麼樣子：

[[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)];

如果你真的不想使用hamcrest出於某種原因，你可以創建你的測試類的方法，用於評估物品陣列。但我認爲這有點難看：

- (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]); 
}
