java - 模拟私有(private)包装器/基元/字符串字段

Question

我的问题不是this问题。我想模拟私有(private)包装字段，例如整数和字符串。此外，这些字段位于抽象父类(super class)中。

public abstract class SuperSample
{
    private Integer var1;
    private String var2;

    private Service service;

    pubic boolean foo()
    {
          int a = service.doStuff(var1, var2);
          return subMethod(a);
    }

    protected abstract boolean subMethod(int var);

    public void setVar1(Integer var1)
    {
        this.va1 = var1;
    }

    public Integer getVar1()
    {
        return var1;
    }

    public void setVar2(String var2)
    {
        this.var2 = var2;
    }

    public String getVar2()
    {
        return var2;
    }

    public void setService(Service service)
    {
        this.service = service;
    }

    public String getService()
    {
        return service;
    }
}

public class Sample extends SuperSample
{
    protected boolean subMethod(int var)
    {
        return var%2==0?true:false;
    }
}

Spring.xml -

<bean id="superSample" class="SuperSample" abstract="true">
    <property name="var1" value="2" />
    <property name="var2" value="cool" />
</bean>

<bean id="sample" class="Sample" >
    <property name="service" ref="service" />
</bean>

在我的 junit 中，我无法模拟或监视 var1 或 var2。在监视/模拟 var1, var2 时，我收到错误:

org.mockito.exceptions.base.MockitoException: Cannot mock/spy class java.lang.Integer Mockito cannot mock/spy following: - final classes - anonymous classes - primitive types

我想模拟这条线 -

service.doStuff(var1, var2)

像这样的东西-

@UnitTest
public class SampleTest
{
    @Mock 
    private Service service;

    private Integer var1 = 2
    private String var2 = "cool";

    @InjectMocks
    private Sample sample;  

    @Test
    public void test()
    {
        MockitoAnnotations.initMocks(this); 
        Mockito.when(service.doStuff(var1, var2)).thenReturn(5);
    }
}

Answer 1

您可以简单地自己注入(inject)值，然后删除@InjectMocks注释。这最好在用 @Before 注释的设置方法中完成，以便为每个测试执行它。

@Before
public void setup() {
    MockitoAnnotations.initMocks(this);
    sample = new Sample();
    sample.setVar1(1234);
    sample.setVar2("5678");
    sample.setService(service);
}
