Spring Boot学习——单元测试

       本随笔记录使用Spring Boot进行单元测试，主要是Service和API（Controller）进行单元测试。

       1、Service单元测试

       选择要测试的service类的方法，使用idea自动建立测试类，步骤以下。（注，我用的是idea自动建立，也能够本身手动建立）

       自动建立测试类以后目录以下图：

       测试类StudentServiceTest.java代码以下：

package *; //本身定义路径

import *.Student; //本身定义路径
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import static org.junit.Assert.*;

@RunWith(SpringRunner.class)
@SpringBootTest
public class StudentServiceTest {
    @Autowired
    private StudentService studentService;

    @Test
    public void findOne() throws Exception {
        Student student = studentService.findOne(1);
        Assert.assertEquals(new Integer(16), student.getAge());
    }
}

       2、API（Controller）单元测试

      根据上面的步骤建立单元测试类StudentControllerTest.java，代码以下：

package *; //本身定义路径

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;
import static org.junit.Assert.*;

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class StudentControllerTest {
    @Autowired
    private MockMvc mvc;

    @Test
    public void getStudentList() throws Exception {
        mvc.perform(MockMvcRequestBuilders.get("/students"))
                .andExpect(MockMvcResultMatchers.status().isOk());
        //.andExpect(MockMvcResultMatchers.content().string("365"));  //测试接口返回内容
    }

}

       3、service和API（Controller）类和方法

       StudentController.java代码以下：

package *; //本身定义路径

import *.StudentRepository; //本身定义路径
import *.Student; //本身定义路径
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.*;
import javax.validation.Valid;
import java.util.List;

@RestController
public class StudentController {
    @Autowired
    private StudentRepository studentRepository;

    /**
     * 查询学生列表
     * @return
     */
    @GetMapping(value = "/students")
    public List<Student> getStudentList(){
        return studentRepository.findAll();
    }
}

       StudentService.java代码以下：

package *; //本身定义路径

import *.StudentRepository; //本身定义路径
import *.Student; //本身定义路径
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class StudentService {
    @Autowired
    private StudentRepository studentRepository;

    /**
     * 根据ID查询学生
     * @param id
     * @return
     */
    public Student findOne(Integer id){
        return studentRepository.findOne( id);
    }
}
