单元测试方法委托 [英] Unit-Testing delegating methods

问题描述

有没有单元测试，它确实的唯一事情是另一个对象委托工作方法的任何一点？例如：

Is there any point in Unit-Testing a method that the only thing it does is delegate work on another object? Example:

class abc {

    ...

    public void MoveLeft()
    {
        fallingPiece.MoveLeft();
    }

    ...
}

我在做单元测试一些现有的类我有，学习的目的。这似乎有点儿奇怪，做单元测试此MoveLeft（）方法，例如。但我不能确定如何将它一直有我做测试先行。

I am doing Unit-Tests for some existing classes I have, for learning purposes. It seems kinda odd to do a Unit-Test for this MoveLeft() method, for example. But I am unsure how would it have been had I done Test-First.

推荐答案

请问你的代码休息，如果我这样做呢？如果可以，那么你需要一个测试来抓住它。

Will your code break if I do this ? If it would, then you need a test to catch it.

class abc {
    ...
    public void MoveLeft()
    {
        // fallingPiece.MoveLeft();
    }
    ...
}

假设：ABC是公开/裸露型和fallingPiece是一个依赖。如果成立，那么你需要一个测试，测试MoveLeft行为。如果它不是一个公共的类型，那么你需要为大众型XYZ使用ABC作为colloborator /依赖性测试。你不直接测试它，但它仍然需要进行测试。

Assumptions: abc is a public / exposed type and fallingPiece is a dependency. If this holds, then you need a test to test the MoveLeft behavior. If it isn't a public type, then you need a test for the public type XYZ that uses abc as a colloborator/dependency. You don't directly test it but it still needs to be tested.
