Question

我在Junit测试类中有一个方法，它测试电子邮件是否已成功更改，问题是它返回了一条错误消息，说明＆＃34; void类型不允许＆＃34;我不确定为什么。

以下是测试电子邮件是否已成功更改但返回上述错误的方法。

  @Test
public void testChangeEmail()
{
    assertEquals("001", teacher.getEmail());
    assertEquals("002", teacher.changeEmail("002"));
    assertEquals("002", teacher.getEmail());

}

这是全班，

import static org.junit.Assert.*;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;


public class TeacherTest
{
    private Teacher teacher;

    /**
     * Default constructor for test class TeacherTest
     */
    public TeacherTest()
    {
    }

    /**
     * Sets up the test fixture.
     *
     * Called before every test case method.
     */
    @Before
    public void setUp()
    {
        teacher = new Teacher("Amy Blunt", "001", "MNHA");
    }

    /**
     * Tears down the test fixture.
     *
     * Called after every test case method.
     */
    @After
    public void tearDown()
    {
    }

    @Test
    public void testGetName()
    {
        assertEquals("Amy Blunt", teacher.getName());
    }

    @Test
    public void testMembership()
    {
        assertEquals("001", teacher.getEmail());
    }


    @Test
    public void testQualifications()
    {
        assertEquals("MNHA", teacher.getQualifications());
    }

    @Test
    public void testChangeEmail()
    {
        assertEquals("001", teacher.getEmail());
        assertEquals("002", teacher.changeEmail("002"));
        assertEquals("002", teacher.getEmail());

    }

}

Answer 1

我猜你的'http://localhost:63342/'方法实际上并没有返回任何内容。

而不是teacher.changeEmail();只需致电assertEquals("002", teacher.changeEmail("002"));。下一个断言检查以确保电子邮件已正确更新。

teacher.changeEmail("002");

Answer 2

您的方法teacher.changeEmail（“002”）返回一些值？如果没有，请更换：
      assertEquals（“002”，teacher.changeEmail（“002”））;
      为此：
      teacher.changeEmail（ “002”）

Junit测试方法返回语句＆＃34; void类型不允许＆＃34;
