如何在JUnit测试中测试列表？

Question

我创建了Survey.java类和SurveyTest.java JUnit测试。 但是我不确定如何在Survey类中测试列表。 如何在JUnit测试中测试它们？

Survey.java

package com.jhaksurvey.model;

import java.util.List;

public class Survey {

private long id;
private String title;
private boolean active = true;
private List<Question> questions;

public Survey() {

}

public Survey(long id, String title) {
this.id=id;
this.title=title;   
}

public long getId() {
return id;
}

public void setId(long id) {
this.id = id;
}

public String getTitle() {
return title;
}

public void setTitle(String title) {
this.title = title;
}

public boolean isActive() {
return active;
}

public void setActive(boolean active) {
this.active = active;
}

public List<Question> getQuestions() {
return questions;
}

public void setQuestions(List<Question> questions) {
this.questions = questions;
}

}

SurveyTest.java

package com.survey.model.test;

import junit.framework.Assert;
import junit.framework.TestCase;

import com.survey.model.Survey;


public class SurveyTest extends TestCase {

private Survey survey;

protected void setUp() throws Exception {
    super.setUp();  
    survey = new Survey();
}

public void testSurvey() {
    survey.toString();
}

public void testSurveyLongString() {
    fail("Not yet implemented");
}

public void testGetId() {
    long expected = (long) Math.random();
    survey.setId(expected);
    long actual = survey.getId();
    Assert.assertEquals(expected, actual);
}

public void testGetTitle() {
    String expected = "surveytitle";
    survey.setTitle(expected);
    String actual = survey.getTitle();
    Assert.assertEquals(expected, actual);  
}

public void testIsActive() {
    Boolean expected = true;
    survey.setActive(expected);
    Boolean actual = survey.isActive();
    Assert.assertEquals(expected, actual);
}

public void testGetQuestions() {
    fail("Not yet implemented");
}

}

Answer 1

该类中没有真正的逻辑，因此您无需测试该类。 您应该只测试包含某种逻辑的类。

Answer 2

Survey.java是包含值的模型/数据结构。 理想情况下，您应该测试使用Survey类的类。 对于前。 CreateSurvey可能是正在创建调查的类，因此您可以对create方法进行单元测试，以确保它适当地设置了调查对象的值。

Answer 3

您可以测试列表是否为空
