Spring Boot H2 简明教程

Spring Boot & H2 - Unit Test Service

要测试服务,我们需要以下注释和类——

  1. @ExtendWith(SpringExtension.class) ——使用SpringExtension类将类标记为以测试用例运行。

  2. @SpringBootTest(classes = SprintBootH2Application.class) - 配置 Spring Boot 应用程序。

  3. @MockBean private EmployeeService employeeService - 要测试的 EmployeeService 模拟对象。

以下是 EmployeeServiceTest 的完整代码。

package com.tutorialspoint.service;
import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertTrue;
import static org.mockito.BDDMockito.given;
import static org.mockito.Mockito.doNothing;
import java.util.ArrayList;
import java.util.List;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.test.context.junit.jupiter.SpringExtension;
import com.tutorialspoint.entity.Employee;
import com.tutorialspoint.sprintbooth2.SprintBootH2Application;
@ExtendWith(SpringExtension.class)
@SpringBootTest(classes = SprintBootH2Application.class)
public class EmployeeServiceTest {
   @MockBean
   private EmployeeService employeeService;
   @Test
   public void testGetAllEmployees() throws Exception {
      Employee employee = getEmployee();
      List<Employee> employees = new ArrayList<>();
      employees.add(employee);
      given(employeeService.getAllEmployees()).willReturn(employees);
      List<Employee> result = employeeService.getAllEmployees();
      assertEquals(result.size(), 1);
   }
   @Test
   public void testGetEmployee() throws Exception {
      Employee employee = getEmployee();
      given(employeeService.getEmployeeById(1)).willReturn(employee);
      Employee result = employeeService.getEmployeeById(1);
      assertEquals(result.getId(), 1);
   }
   @Test
   public void testDeleteEmployee() throws Exception {
      doNothing().when(employeeService).deleteEmployeeById(1);
      employeeService.deleteEmployeeById(1);
      assertTrue(true);
   }
   @Test
   public void testSaveOrUpdateEmployee() throws Exception {
      Employee employee = getEmployee();
      doNothing().when(employeeService).saveOrUpdate(employee);
      employeeService.saveOrUpdate(employee);
      assertTrue(true);
   }
   private Employee getEmployee() {
      Employee employee = new Employee();
      employee.setId(1);
      employee.setName("Mahesh");
      employee.setAge(30);
      employee.setEmail("mahesh@test.com");
      return employee;
   }
}

Run the test cases.

在 Eclipse 中右键单击该文件并选择 Run a JUnit Test ,然后验证结果。
