Java 如何进行if的junittestelse分支

我正在尝试对该方法进行Junit测试

  public List<QuestionBank> getQuestionBankDetails(){
            if(stubbed){
                return (List<QuestionBank>) BeanPopulateUtils.getPopulateBeanValues(new QuestionBank(), true);
            }else{
                throw new NotImplementedException("Non-stubbed SOAP call not implemented");
            }
        }

---

如果stubbed是类变量，请创建一个对象并将该变量设置为false。然后调用函数

getQuestionBankDetails（）。这样，您就可以检查else部分，因为缺少代码。我假设您的
类如下所示：

private boolean stubbed;

public boolean isStubbed() {
    return stubbed;
}

public void setIsStubbed(boolean isStubbed) {
    this.stubbed = isStubbed;
}

public List<QuestionBank> getQuestionBankDetails() {
    if (stubbed) {
        return (List<QuestionBank>) BeanPopulateUtils.getPopulateBeanValues(new QuestionBank(), true);
    }
    throw new NotImplementedException("Non-stubbed SOAP call not implemented");
}

@Test(expected=NotImplementedException.class)
public void getQuestionBankDetailsThrowsAnExceptionIfStubbed() {
    boolean memento = questionBankFacade.isStubbed();
    questionBankFacade.setIsStubbed(false);
    try {
        questionBankFacade.getQuestionBankDetails();
    } finally {
        questionBankFacade.setIsStubbed(memento);
    }
}

您需要编写一个单独的测试方法来测试else条件代码路径。
如果可能，尝试使用接口来区分存根实现和默认实现。最好使用配置逻辑来“注入”正确的行为，或者使用工厂来生成请求的类实例

请参见以下示例：

private boolean stubbed;

public boolean isStubbed() {
    return stubbed;
}

public void setIsStubbed(boolean isStubbed) {
    this.stubbed = isStubbed;
}

public List<QuestionBank> getQuestionBankDetails() {
    if (stubbed) {
        return (List<QuestionBank>) BeanPopulateUtils.getPopulateBeanValues(new QuestionBank(), true);
    }
    throw new NotImplementedException("Non-stubbed SOAP call not implemented");
}

@Test(expected=NotImplementedException.class)
public void getQuestionBankDetailsThrowsAnExceptionIfStubbed() {
    boolean memento = questionBankFacade.isStubbed();
    questionBankFacade.setIsStubbed(false);
    try {
        questionBankFacade.getQuestionBankDetails();
    } finally {
        questionBankFacade.setIsStubbed(memento);
    }
}

银行详情.类别

package example;

import java.util.List;

public interface BankDetails {
    List<QuestionBank> getQuestionBankDetails();
}

最后是JUnit测试：

问题库FacadeTest.class

package example;

import static org.junit.Assert.*;

import java.util.List;

import org.apache.commons.lang.NotImplementedException;
import org.junit.Test;

public class QuestionBankFacadeTest {

    @Test
    public void testDefaultImplementation() {
        final QuestionBankFacade questionBankFacade = new QuestionBankFacade(new BankDetailsDefaultImpl());
        List<QuestionBank> questionBankList = questionBankFacade.getQuestionBankDetails();
        //Test case that you already have
//       for(QuestionBank questionBank : questionBankList){
//             assertEquals("Name "+i+"", questionBank.getName());
//             assertEquals("Description "+i+"", questionBank.getDescription());
//             assertEquals("Pubished Status "+i+" ", questionBank.getPubishedStatus());
//             assertEquals("Questions "+i+"", questionBank.getQuestions());
//             i++;
//         }
    }

    @Test(expected = NotImplementedException.class)
    public void testStubbedImplementation() {
        final QuestionBankFacade questionBankFacade = new QuestionBankFacade(new BankDetailsStubbedImpl());
        questionBankFacade.getQuestionBankDetails();
    }

}
