Spring、Spring MVC、mybatis框架使用junit完成单元测试

之前对一个方法是否执行正确的判断上，总是凭自己的感觉或等到最后调用并执行的时候才可以看出开。今天使用junit完成了对方法的测试，现对该方法进行记录，希望可以帮助到你们。

• 添加相关测试依赖

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.7</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>${org.springframework-version}</version>
    <scope>test</scope>
</dependency>

• 这里以我的一个简单项目来演示
  
  1. 在对应的包下选择并创建测试用例
     
  2. 填写测试用例名称并选择类中的相关方法,并点击Finish完成测试用例的创建
     
     
     
  3. 在测试类中添加相关注解
     

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath*:root-context.xml", "classpath*:servlet-context.xml" })  //引入两个配置文件
@TransactionConfiguration(defaultRollback = true, transactionManager = "transactionmanager")  //使用事务，避免运行测试对数据的影响
@Transactional

4 .再次就完成了测试类的创建和配置
5. 注入所需要的bean

package com.example.oa.test;

import static org.junit.Assert.*;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.transaction.TransactionConfiguration;
import org.springframework.transaction.annotation.Transactional;

import com.example.oa.domain.Employee;
import com.example.oa.service.EmployeeService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath*:root-context.xml", "classpath*:servlet-context.xml" })
@TransactionConfiguration(defaultRollback = true, transactionManager = "transactionmanager")
@Transactional
public class EmployeeTest {
    @Autowired
    private EmployeeService employeeService;   //注入所需的bean(记得要在实现类上添加相关注解)

    @Test
    public void testIsUser() {
        boolean hasuser = employeeService.getuserByUPR("890", "7987", 0);
        assertEquals(true, hasuser);
    }

    @Test
    public void testForgetPassword() {
        Employee e = new Employee();
        e.setEmployee_account("6");
        e.setRole(0);
        e.setPassword("555");
        boolean isupdate = employeeService.updatePassword(e);
        assertEquals(true, isupdate);
    }

    @Test
    public void testDeleteEmployee() {
        Employee e = new Employee();
        e.setEmployee_id(7);
        boolean isdelete = employeeService.deleteEmployee(e);
        assertEquals(true, isdelete);
    }

    @Test
    public void testAddEmployee() {
        Employee e = new Employee();
        e.setEmployee_account("555");
        e.setUsername("555");
        e.setPassword("666");
        e.setAge(45);
        e.setAddress("四川省成都市");
        e.setDepartmentid(2);
        e.setRole(0);
        boolean isadded = employeeService.addEmployee(e);
        assertEquals(true, isadded);
    }

}
