JUnit测试:通过模拟抑制枚举构造函数?

问题描述：

我知道可以模拟单个枚举(使用

I know that it is possible to mock a single enum(using How to mock an enum singleton class using Mockito/Powermock?), but I have like 1000 of enum values and they can call 5 different constructors. The enum values are often changing in development.

对于我的JUnit测试，我只想真正模拟一个或两个.我不在乎其余的，但是它们仍然被实例化，这调用了一些讨厌的东西，这些东西从文件系统中加载了枚举的值.

I want to really mock only one or two for my JUnit test. I don't care about the rest, but they are still instantiated, which calls some nasty stuff, which loads the values for the enum from the file system.

是的，我知道这是非常糟糕的设计.但是目前我还没有时间进行更改.

Yes I know It's very bad design. But for now I don't get the time to change it.

目前，我们正在使用Mockito/powermock.但是任何可以解决这个问题的框架，**我的意思是欢迎不良的设计.

At the moment we have Mockito/powermock in use. But any framework, which can solve this sh** I mean bad design is welcome.

假设我有一个与此类似的枚举:

Let's say I have an enum similar to this:

public static enum MyEnum {
   A(OtherEnum.CONSTANT),
   B("1"),
   C("1", OtherEnum.CONSTANT),
   //...and so on for again 1000 enum values :(

   private double value;
   private String defaultValue;
   private OtherEnum value;

   /* Getter/Setter */
   /* constructors */
}

答

我同意Nick-Holt的建议，他建议添加一个接口:

I agree with Nick-Holt who suggested adding an interface:

 public interface myInterface{

     //add the getters/setters you want to test

 }

public enum MyEnum implements MyInterface{

    //no changes needed to the implementations
    //since they already implement the methods you want to use

}

现在您可以使用Mockito的普通模拟功能，而不必依赖Powermock

Now you can use the normal mock abilities of Mockito without having to rely on Powermock

MyInterface mock = Mockito.mock(MyInterface.class);
when(mock.foo()).thenReturn(...);
//..etc
