org.mockito.internal.stubbing.ConsecutiveStubbin

问题描述

我是Mockito / Junit的新手，我的任务是对一些旧代码进行一些测试。我创建了一个测试类，但收到了ContinuousStubbing错误，我似乎无法弄清楚。我希望有人可以向我解释错误。

试图在网上搜索，但缺少错误的结果（Mockito文档除外）。

这是测试

import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.when;

import org.junit.After;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.runners.MockitoJUnitRunner;
import org.mockito.stubbing.OngoingStubbing;

import cbsa.enrolment.entities.Trgc202Evnt;

@RunWith(MockitoJUnitRunner.class)
public class EventDisplayTest {
    
//  @InjectMocks
//  Trgc202Evnt trgEvnt;
    
    @Mock
    EventDisplay evntDsp;
    
    //String rslt;

    @Before
    public void setUp() throws Exception {
    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void testGetDescription() {
        Trgc202Evnt trgEvnt = new Trgc202Evnt();
        evntDsp = mock(EventDisplay.class);
        Short docType = (short) 3;  //Type Document
        trgEvnt.setEvntEntyTcsn(docType);  // set the docType before all
        String expectedRslts1 = "Drivers Licence Document Captured"; // expected text returned
        
        OngoingStubbing<String> rslt = when(evntDsp.getDescription(trgEvnt)).thenReturn("Drivers Licence Document Captured");

        Assert.assertEquals("### EvenDisplay getDescription(document type) failed. ###",expectedRslts1,rslt);
// This Line causing the error,I think because *rslt* is stubbed but if I change it to a String then Mockito error says it must be converted to OngoingStubbing

    }
} 


this is the stack trace

解决方法

我可以通过测试，但是我不确定测试的正确方法。

在setup（）中声明一些变量后，我将测试功能更改为以下内容

@测试 公共无效testGetDescription（）{

String expectedRslts1 = "Drivers Licence Document Captured"; // expected text returned

when(evntDsp.getDescription(trgEvnt)).thenReturn("Drivers Licence Document Captured");
Assert.assertEquals("### EvenDisplay getDescription(document type) failed. ###",expectedRslts1,evntDsp.getDescription(trgEvnt));

}

这是对getDescription（）方法的有效测试吗？
