Question

我正在使用基于java配置的spring boot。我有以下类结构

@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;
    }
}

此处的代理对象调用外部系统。我想通过模拟代理对象来编写集成测试。你能给我一些指导，告诉我如何在这个结构中注入模拟代理对象。

Answer 1

您可以在调用ProxyFactory.get（String value，String id）时模拟ProxyFactory并返回代理的模拟

我喜欢在我的单元测试中使用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();
    }

}

Spring启动集成测试通过autowire注入模拟对象
