使用 Mockito 2 模拟最终课程

2022-01-14 00:00:00 unit-testing mockito java

我正在从我目前正在处理的项目中删除 Powermock，因此我正在尝试仅使用 Mockito (mockito-core-2.2.28) 重写一些现有的单一测试.

I'm removing Powermock from the project I'm currently working on, so I'm trying to rewrite some existing unitary test only with Mockito (mockito-core-2.2.28).

当我运行测试时，出现以下错误:

When I run the test, I have the following error:

org.mockito.exceptions.base.MockitoException:

org.mockito.exceptions.base.MockitoException:

无法模拟/监视类 com.ExternalpackagePath.Externalclass

Cannot mock/spy class com.ExternalpackagePath.Externalclass

Mockito 无法模拟/窥探，因为:

Mockito cannot mock/spy because :

  • 最后一节课

我知道这个问题已经被问过了(如何模拟带有 mockito 的 final 类，模拟对象调用 final使用 Mockito 类静态方法)，但我没有找到我正在寻找的答案.

I know that this question has already been asked (How to mock a final class with mockito, Mock objects calling final classes static methods with Mockito), but I didn't find the answer I'm looking for.

这是我的代码摘录:

public class MyClassToTest extends TestCase {
    private MyClass myClass;
    @Mock private Externalclass ext;  // This class is final, I would like to mock it

    @Override
    protected void setUp() throws Exception {
        MockitoAnnotations.initMocks(this); // <<<< The exception is thrown here
        ext = Mockito.mock(Externalclass.class);
    }
}

如 Mockito 文档中所述(https://github.com/mockito/mockito/wiki/What%27s-new-in-Mockito-2，§Mock the unmockable)，我添加了 org.mockito.plugins.MockMaker 文件.这是我项目的树:

As mentioned in the Mockito documentation (https://github.com/mockito/mockito/wiki/What%27s-new-in-Mockito-2, §Mock the unmockable), I added the org.mockito.plugins.MockMaker file. This is the tree of my project :

  • 项目
    • 源代码
      • com.packagePath.myPackage
        • 我的班级
        • com.packagePath.myPackage
          • myClassToTest
          • 模拟扩展
            • org.mockito.plugins.MockMaker

            我也尝试将资源"放在src"中的目录，在名为test"的子目录中，但结果仍然相同.

            I also tries to put the "resources" directory in "src", in a subdir called "test", but the result is still the same.

            我认为使用 Mockito v2 可以模拟决赛.有人知道这里缺少什么吗?

            I thought that mocking a final was possible with Mockito v2. Does someone have an idea of what is missing here ?

            谢谢！

            推荐答案

            好吧，我发现这里有什么问题，它可能对其他人有用.我的项目树错了，我把org.mockito.plugins.MockMaker直接放到了src"的一个目录mockito-extension"中.这是我现在的树:

            Well, I found what's wrong here, it maybe useful for other people. My project tree is wrong, I put the org.mockito.plugins.MockMaker in a directory "mockito-extension" directly in "src". This is my tree now:

            • 项目
              • 源代码
                • com.packagePath.myPackage
                  • 我的班级
                  • org.mockito.plugins.MockMaker
                  • com.packagePath.myPackage
                    • myClassToTest
