問題描述

是否可以使用 EasyMock 創(chuàng)建一個實(shí)現(xiàn)多個接口的模擬對象?

Is it possible to create a mock object that implements several interfaces with EasyMock?

例如接口Foo和接口Closeable?

在 Rhino Mocks 中，你可以在創(chuàng)建 mock 對象時提供多個接口，但 EasyMock 的 createMock() 方法只接受一種類型.

In Rhino Mocks you can provide multiple interfaces when creating a mock object, but EasyMock's createMock() method only takes one type.

是否可以使用 EasyMock 來實(shí)現(xiàn)這一點(diǎn)，而無需求助于創(chuàng)建一個擴(kuò)展 Foo 和 Closeable 的臨時接口，然后對其進(jìn)行模擬?

Is it possbile to achieve this with EasyMock, without resorting to the fallback of creating a temporary interface that extends both Foo and Closeable, and then mocking that?

推薦答案

EasyMock 不支持此功能，因此您只能使用臨時界面的回退.

EasyMock doesn't support this so you're stuck with fallback of the temporary interface.

順便說一句，我聞到了一點(diǎn)代碼的味道——如果一個方法真的將一個對象視為 2 個不同的東西，Foo 和 Closeable 接口這個案例?

As an aside, I smell a little bit of a code wiff - should a method really be treating an object as 2 different things, the Foo and Closeable interface in this case?

這對我來說意味著該方法正在執(zhí)行多個操作，雖然我懷疑其中一個操作是關(guān)閉"Closeable，但調(diào)用代碼決定是否更有意義是否需要關(guān)閉"?

This implies to me that the method is performing multiple operations and while I suspect one of those operations is to 'close' the Closeable, wouldn't it make more sense for the calling code to decide whether or not the 'close' is required?

以這種方式構(gòu)建代碼將打開"和關(guān)閉"保持在同一個 try ... finally 塊中，恕我直言，讓代碼更具可讀性，更不用說該方法更通用，并允許您傳遞僅實(shí)現(xiàn) Foo 的對象.

Structuring the code this way keeps the 'open' and 'close' in the same try ... finally block and IMHO makes the code more readable not to mention the method more general and allows you to pass objects that only implement Foo.
