org.mockito.internal.stubbing.ConsecutiveStubbin

Question

我是Mockito/Junit的新手，我的任务是在一些旧代码中实现一些测试。我已经创建了一个测试类，但收到了连续的Stubbing错误，我似乎无法理解。我希望有人能向我解释这个错误。

尝试在网络上搜索，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

Answer 1

我让测试开始工作，但我不相信这是正确的方法。

在setup((中声明了一些变量后，我将测试函数更改为以下内容

@测试public void 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？
