Spring引导集成测试通过自动注入注入模拟对象

Question

我正在使用基于java的配置的弹簧引导。我有以下课程结构

@Service 
public class Service implements IService{ 
    @autowire 
    private IProcessor processor; 

    public void perform(Parameter param){ 
     processor.process(param); 
    } 
} 

@Service 
public class Processor implements IProcessor { 
    @autowire 
    private ProxyFactory factory; 

    public void process(Parameter param){ 
     final ExternalSysProxy proxy = factory.get(param.getValue(), param.getId()); 
     proxy.call(); 
    } 
} 

@Repository 
public class ProxyFactory { 
    public Proxy get(String value, String id){ 
     final ExternalSysProxy proxy = new proxy(value, id); 
     return proxy; 
    } 
} 

这里的代理对象调用外部系统。我想通过模仿代理对象来编写集成测试。你能给我一些指导，我可以如何在这个结构中注入模拟代理对象。

你可以嘲笑ProxyFactory里并返回代理的模拟电话时ProxyFactory.get（字符串值，字符串ID）

我喜欢在我的单元测试使用的Mockito：

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; 

@RunWith(MockitoJUnitRunner.class) 
public class ProcessorTest { 

    @InjectMocks 
    private Processor processor; 

    @Mock 
    private ProxyFactory proxyFactoryMock; 

    @Mock 
    private Proxy proxyMock; 

    @Test 
    public void myTest() { 
     Mockito.when(proxyFactoryMock.get("value", "id")).thenReturn(proxyMock); 

     processor.process(new Parameter("value", "id")); 

     Mockito.verify(proxyMock, Mockito.times(1)).call(); 
    } 

}
