@TestSubject和@InjectMocks之间的区别？

Question

在学习Mockito时,我在下面的参考文献中找到了两个不同的注释@TestSubject和@InjectMocks.
@TestSubject Ref
@InjectMocks Ref

@InjectMocks annotation正如教程中所解释的那样工作得很好但@TestSubject不起作用而不是显示错误.
我在下面的代码片段中收到TestSubject cannot be resolved to a type了@TestSubject注释错误,但是我已经做了正确的设置(包括构建路径中的Junit和Mockito jar文件).

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.runners.MockitoJUnitRunner;

import com.infosys.junitinteg.action.MathApplication;
import com.infosys.junitinteg.service.CalculatorService;

@RunWith(MockitoJUnitRunner.class)
public class MathApplicationTester {

    // @TestSubject annotation is used to identify class which is going to use
    // the mock object
    @TestSubject
    MathApplication mathApplication = new MathApplication();

    // @Mock annotation is used to create the mock object to be injected
    @Mock
    CalculatorService calcService;

    @Test(expected = RuntimeException.class)
    public void testAdd() {
        // add the behavior to throw exception
        Mockito.doThrow(new RuntimeException("Add operation not implemented")).when(calcService).add(10.0, 20.0);

        // test the add functionality
        Assert.assertEquals(mathApplication.add(10.0, 20.0), 30.0, 0);
    }
}

我这里有两个问题.
有人遇到过类似的问题吗？如果是,那么根本原因和解决方案是什么？
2.如果它工作正常那么注释@TestSubject和@InjectMocks注释之间有什么区别？

Answer 1

@TestSubject是EasyMock的注释,它和Mockito的@InjectMocks一样.如果您正在使用Mockito,那么您必须使用@InjectMocks.
