ios - 测试目标下未调用 MagicalRecord 完成 block

Question

MagicalRecord.saveWithBlock({ context in

        if let items = dictionary["items"] as? Array<NSDictionary> {
            for itemInfo in items {
                DBItem.findOrUpdateItemWithDictionary(itemInfo, inContext: context)
            }
        }
        //is called
        if let sets = dictionary["item_sets"] as? Array<NSDictionary> {
            for setInfo in sets {
                DBSet.findOrUpdateSetWithDictionary(setInfo, inContext: context)
            }
        }

        }, completion: { finished, error in

        completionBlock(error) //is not called
})

这就是我设置核心数据堆栈的方式:

MagicalRecord.setupCoreDataStackWithInMemoryStore()

saveWithBlock: 方法是异步执行的。尽管我不知道您的测试代码如何，但测试可能会在调用完成 block 之前完成。

https://github.com/magicalpanda/MagicalRecord/blob/c7b14f658b4fca32f8d33f8f76160203053ce4b9/MagicalRecord/Core/MagicalRecord%2BActions.m#L14-L35

您能否尝试将 saveWithBlock: 方法更改为 saveWithBlockAndWait:？它是同步执行的。或者等待使用XCTestExpectation 执行异步调用？
