Question

我按照github的例子来测试我自己的RKModel：

使用fixtures在Restkit上开始我的单元测试后，我找不到通过他们测试嵌套关系数据映射的测试用例。

我的夹具 - articles.json：

{
"articles": [
             {
             "title": "RestKit Unit Testing",
             "author": "Blake Watters",
             "tags": [
                      "RestKit",
                      "testing",
                      "tutorials"
                      ]
             },
             {
             "title": "RestKit Unit Testing2",
             "author": "Blake Watters",
             "tags": [
                      "RestKit",
                      "testing",
                      "tutorials"
                      ]
             },
             {
             "title": "RestKit Unit Testing3",
             "author": "Blake Watters",
             "tags": [
                      "RestKit",
                      "testing",
                      "tutorials"
                      ]
             }
             ]
}

我的测试用例：

- (void)testArticlesMapping
{
    id parsedJSON = [RKTestFixture parsedObjectWithContentsOfFixture:@"articles.json"];


    RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[RKArticle class]];
    [mapping addAttributeMappingsFromDictionary:@{
                                                  @"title":   @"title",
                                                  @"author":  @"author",
                                                  @"tags":    @"tags"
                                                  }];

    RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping method:RKRequestMethodAny pathPattern:nil keyPath:@"articles" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

    [[RKObjectManager sharedManager] addResponseDescriptor:responseDescriptor];

    RKMappingTest *test = [RKMappingTest testForMapping:mapping sourceObject:parsedJSON destinationObject:nil];

    [test addExpectation:[RKPropertyMappingTestExpectation expectationWithSourceKeyPath:@"title" destinationKeyPath:@"title" value:@"RestKit Unit Testing"]];
    [test addExpectation:[RKPropertyMappingTestExpectation expectationWithSourceKeyPath:@"author" destinationKeyPath:@"author" value:@"Blake Watters"]];
    [test addExpectation:[RKPropertyMappingTestExpectation expectationWithSourceKeyPath:@"tags" destinationKeyPath:@"tags" value:@[ @"RestKit", @"testing", @"tutorials"]]];


    XCTAssertTrue([test evaluate]);
    XCTAssertNoThrow([test verify]);
}

夹具已加载，但收到错误：

（（[test evaluate]）为真）失败：抛出“0x112701a20：失败了错误：错误Domain = org.restkit.RestKit.ErrorDomain Code = 1003“No 找到任何属性或关系的可映射值映射“UserInfo = 0x112703bb0 {NSLocalizedDescription = No mappable 为任何属性或关系映射找到的值}

似乎无法找到嵌套值，因为尚未设置responseDescriptor。如何解决嵌套关系数据的这些测试？

非常感谢！

RKMappingTest用于测试单个映射，而不是映射集合。所以，一个字典，而不是一个字典数组。如果要测试映射集合（以及关联的密钥路径），则需要更改方法以测试响应描述符。

您需要更改您尝试测试的内容或您尝试测试的内容。

Restkit如何通过Fixture测试嵌套关系数据？
