java - easymock意外行为

我不确定我在做什么错。我的代码中存在此错误，因此我写了一个简单的示例来尝试确定错误所在。

我有一个ClassA，它依赖于ServiceA和ServiceB两个服务，我正在尝试测试ClassA，并模拟ServiceA和ServiceB。

package easy;

import java.util.HashMap;

public class ClassA {
    private ServiceA serviceA;
    private ServiceB serviceB;
    public ClassA(ServiceA a, ServiceB b) {
        this.serviceA = a;
        this.serviceB = b;
    }
    public String process(String p) {
        HashMap<String,String> a = serviceA.getServiceA(p);
        String ret = serviceB.getServiceB(a);
        return ret;
    }
}


interface ServiceA{
    HashMap<String,String>getServiceA(String s);
}

interface ServiceB{
    String getServiceB(HashMap<String,String> p);
}

我的测试如下：

    @Test
    public void testProcess() {
        IMocksControl mockery = EasyMock.createControl();
        mockery.resetToStrict();
        mockery.checkOrder(true);

        ServiceA serviceA = EasyMock.createMock("ServiceA",ServiceA.class);
        ServiceB serviceB = EasyMock.createMock("ServiceB",ServiceB.class);

        ClassA a = new ClassA(serviceA, serviceB);

        String myParam = "My Test";

        HashMap<String,String> retFromServiceA = new HashMap<String,String>();
        retFromServiceA.put("my", "name");
        expect(serviceA.getServiceA(eq(myParam))).andReturn(retFromServiceA);
        expect(serviceB.getServiceB(retFromServiceA)).andReturn(myParam);

        mockery.replay();
        String actual = a.process(myParam);
        mockery.verify();

        Assert.assertEquals(myParam, actual);
    }
}

结果失败，因为实际的回报为空。

我尝试调试代码，但我意识到尽管我期望我说我希望ServiceA.getServiceA返回retFromServiceA，但事实并非如此。它返回null。

有任何想法吗？

最佳答案

ServiceS和ServiceS是在不使用嘲笑控件的情况下创建的，因此应使用：

EasyMock.replay(serviceA, serviceB);

在执行处理方法之前
