使用Mockito在春季进行单元测试

[英]Unit test in spring using Mockito

Today while working with Mockito and spring I got struck with this scenario, 今天和Mockito一起工作时,春天,我对这种情况感到震惊,

    public class MyClass {

    private MyService myService;

    int doSomethingElse(String str) {
        .....
        myService.doSomething(str);
        ...
    }
}

public interface MyService {
    String doSomething(String str);
}


public class Class1 {
    private MyClass myClass;

    public Stirng methodToBeTested() {
        myClass.doSomethingElse("..");
    }
}

public class class1Test {

    @Mock
    MyService myService;

    @Resource
    @Spy
    @InjectMocks
    MyClass myClass;

    @Resource
    @InjectMocks
    Class1 class1;

    public void setUPTest() {
        MockitoAnnotations.initMocks(this);
    }

    @Test
    public void methodToBeTestedTest() {
        this.setUPTest();
            ...
            class1.methodToBeTested();
    }

}

Here I want to mock "MyService". 在这里,我要模拟“ MyService”。 But MyService is used in "MyClass" and it is used in "Class1" . 但是MyService在“ MyClass”中使用,而在“ Class1”中使用。

I want to initialise "MyClass" and "Class1" using spring. 我想使用spring初始化“ MyClass”和“ Class1”。

When I try to run this test, I got the following exception 当我尝试运行此测试时,出现以下异常

org.mockito.exceptions.base.MockitoException: Cannot mock/spy class $Proxy79 Mockito cannot mock/spy following: - final classes - anonymous classes - primitive types org.mockito.exceptions.base.MockitoException:无法模拟/间谍类$ Proxy79 Mockito无法模拟/间谍以下:-最终类-匿名类-基本类型

Can anyone help me with this? 谁能帮我这个?

You are testing Class1 , which only has MyClass as dependency. 您正在测试Class1 ,它仅将MyClass作为依赖项。 MyService is irrelevant to this test. MyService与该测试无关。 You should mock MyClass and test the call to doSomethingElse . 您应该模拟MyClass并测试对doSomethingElse的调用。

If you wish to test the call to doSomething of MyService , you should write a MyClassTest which mocks the dependency to MyService . 如果您希望测试对MyService doSomething的调用,则应编写一个MyClassTestMyService的依赖关系。
