我正在为使用核心数据的模型文件运行单元测试。测试目标构建成功，但我看到以下错误：

错误：testThatDistinguishedFolderTypeForTheAccountExists (FolderDALTests) 失败：+entityForName：无法在此模型中找到名为“文件夹”的实体。

错误：testThatFindByExchageAccountReturnsFolders (FolderDALTests) 失败：+entityForName：无法在此模型中找到名为“ExchangeAccount”的实体。

但是，我觉得问题是由于“设置”方法引起的，其中 NSManagedObjectModel 不是通过合并捆绑包中的所有模型来创建的。

-(void)testThatDistinguishedFolderTypeForTheAccountExists
 {
   Folder *inbox = [NSEntityDescription insertNewObjectForEntityForName:@"Folder" 
   inManagedObjectContext:self.context];
   inbox.distinguishedFolderType = @"inbox";
   ExchangeAccount *account = [NSEntityDescription insertNewObjectForEntityForName:@"ExchangeAccount" inManagedObjectContext:self.context];
   id<FolderProtocol> folder = [FolderDAL findWithAccount:account DistinguishedFolderType:@"inbox" withManagedContext:self.context];

STAssertTrue([folder.folderDistinguishedFolderType isEqualToString:@"inbox"], @"Unable to find the folder with the given distinguished type");

}

另一种方法是：

- (void)testThatFindByExchageAccountReturnsFolders
  {
      ExchangeAccount *account = [NSEntityDescription          insertNewObjectForEntityForName:@"ExchangeAccount" inManagedObjectContext:self.context];

     Folder *inbox = [NSEntityDescription insertNewObjectForEntityForName:@"Folder"     inManagedObjectContext:self.context];
     inbox.displayName = @"Inbox";
     inbox.exchangeAccount = account;

     Folder *calendars = [NSEntityDescription insertNewObjectForEntityForName:@"Folder" inManagedObjectContext:self.context];
     calendars.displayName = @"Calendars";
     calendars.exchangeAccount = account;

     NSArray *folders = [FolderDAL findByExchangeAccount:account withContext:self.context];

     STAssertTrue([folders count] > 0, @"No folders were returned");
  }

设置方法是：

- (void)setUp
{
  [super setUp];

  NSManagedObjectModel *objectModel = [NSManagedObjectModel mergedModelFromBundles:[NSArray arrayWithObject:[NSBundle mainBundle]]];
  NSPersistentStoreCoordinator *storeCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:objectModel];
  STAssertTrue([storeCoordinator addPersistentStoreWithType:NSInMemoryStoreType configuration:nil URL:nil options:nil error:NULL] ? YES : NO, @"Should be able to add in-memory store");
  self.context = [[NSManagedObjectContext alloc] init];
  self.context.persistentStoreCoordinator = storeCoordinator;

}

这里，“Folder”和“ExchangeAccount”是核心数据实体。而它们对应的DAL(Data Access Layer)文件也有一些业务逻辑

我忘记将单元测试作为目标添加到架构中。
