Spring Boot 和 H2 - 单元测试服务
要测试服务,我们需要以下注解和类 −
@ExtendWith(SpringExtension.class) − 使用 SpringExtension 类将该类标记为作为测试用例运行。
@SpringBootTest(classes = SprintBootH2Application.class) − 配置 Spring Boot 应用程序。
@MockBean private EmployeeService employeeService − EmployeeService 要测试的模拟对象。
以下是 EmployeeServiceTest 的完整代码。

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 {

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;
}
}
