Question

我写了以下方法：

public void checkIfPlansPublishMailShouldBeSent(
        boolean allPlansPublished, String currentPhase,
        String chaseIterationCount, LoadConfig config,
        String clientFolderName, LoggerHandler logger){
    if(allPlansPublished){
        sendPlansPublishMail(
            currentPhase, chaseIterationCount, config, clientFolderName,logger);
    }else{
        System.out.println(
            "allPlansPublish is set to false, Plans Publish Mail not sent out");
    }
}

我需要为它编写一个JUnit测试。我还需要模拟sendPlansPublishMail，因为如果它运行会发送电子邮件。

我正在使用Mockito来模拟方法所属的Object（ReportSyncCheck）。

有没有办法验证是否正在调用sendPlansPublishMail而不必将模拟对象作为参数传递给checkIfPlansPublishMailShouldBeSent？

也可以使用其他测试方法。因为我需要编写JUnit测试，所以我不希望将所需的每个Object作为参数传递，因为我想我的方法将具有大的方法签名。

我编写了一个JUnit测试，它将mock对象作为参数传递，我试图避免这样做：

public class checkIfPlansPublishMailShouldBeSentTest {

    ReportSyncCheck mockRSC;
    ReportSyncCheck RSCtoTest;
    LoggerHandler mockLogger;
    LoadConfig mockLoadConfig;
    boolean allPlansPublished;
    String currentPhase;
    String chaseIterationCount;
    String clientFolderName;
    @Before
    public void setUp() throws Exception {
        mockRSC = mock(ReportSyncCheck.class);
        RSCtoTest = new ReportSyncCheck();
        mockLogger = mock(LoggerHandler.class);
        mockLoadConfig = mock(LoadConfig.class);
        currentPhase = "Time Submission Chase";
        chaseIterationCount ="1";
        clientFolderName = "TestClient";

    }

    @Test
    public void testMailMethodcalledWhenAllPlansPublishedIsSetToFalse() {
        allPlansPublished =true;
        RSCtoTest.checkIfPlansPublishMailShouldBeSent(allPlansPublished, currentPhase, chaseIterationCount, mockLoadConfig, clientFolderName, mockLogger,mockRSC);
        verify(mockRSC).sendPlansPublishMail(currentPhase, chaseIterationCount, mockLoadConfig, clientFolderName, mockLogger);
    }

    @Test
    public void testMailMethodcalledWhenAllPlansPublishedIsSetToTrue() {
        allPlansPublished =false;
        RSCtoTest.checkIfPlansPublishMailShouldBeSent(allPlansPublished, currentPhase, chaseIterationCount, mockLoadConfig, clientFolderName, mockLogger,mockRSC);
        verify(mockRSC,times(0)).sendPlansPublishMail(currentPhase, chaseIterationCount, mockLoadConfig, clientFolderName, mockLogger);
    }

}

您应该检查org.mockito.Mockito.verify和org.mockito.BDDMockito.given这是您想要的。

http://gojko.net/2009/10/23/mockito-in-six-easy-examples/和http://www.javahotchocolate.com/notes/mockito.html

也是很好的例子

您正在使用Mockito来模拟您的依赖项，以便您可以将测试集中在被测试的类上。好。

在对象中注入依赖项的最常用方法是在构造时使用它的构造函数。构建服务对象，将其所有依赖项注入到类的构造函数中：

public class MyService {
  private final MyDao dao;

  public MyService(MyDao dao){
    this.dao = dao;
  }

  public String myMethod(){
    return dao.find();
  }
}

或者，一种流行的方法是使用setter注入依赖项：

  public class MyOtherService {
  private MyDao dao;

  public void setDao(MyDao dao){
    this.dao = dao;
  }

  public String myMethod(){
    return dao.find();
  }
}

你需要间谍来做部分行为。

public class checkIfPlansPublishMailShouldBeSentTest {


    ReportSyncCheck mockRSC;

    LoggerHandler mockLogger;
    LoadConfig mockLoadConfig;
    boolean allPlansPublished;
    String currentPhase;
    String chaseIterationCount;
    String clientFolderName;

    @Before
    public void setUp() throws Exception {
        mockRSC = spy(ReportSyncCheck.class);

        mockLogger = mock(LoggerHandler.class);
        mockLoadConfig = mock(LoadConfig.class);
        currentPhase = "Time Submission Chase";
        chaseIterationCount ="1";
        clientFolderName = "TestClient";

    }


    @Test
    public void testMailMethodcalledWhenAllPlansPublishedIsSetToFalse() {
        doNothing().when(mockRSC).sendPlansPublishMail(currentPhase, chaseIterationCount, mockLoadConfig, clientFolderName, mockLogger);
        allPlansPublished =true;
        mockRSC.checkIfPlansPublishMailShouldBeSent(allPlansPublished, currentPhase, chaseIterationCount, mockLoadConfig, clientFolderName, mockLogger,mockRSC);
        verify(mockRSC).sendPlansPublishMail(currentPhase, chaseIterationCount, mockLoadConfig, clientFolderName, mockLogger);
    }

模拟void对象而不传递它们
