}

现要对这个登录业务进行测试，要测试的情况有 登录成功，账号或电话输入错误，密码输入错误三种情况

异常状态码

单元测试

通过断言对失败的情况进行判定，通过Assertions.assertEquals进行进一步判定异常的具体出错信息。

@SpringBootTest
public class EmployeeControllerTests {@Resourceprivate EmployeeController employeeController;@Test//成功的情况public void testLoginSuccess() {Employee employee = new Employee();employee.setUsername("admin");employee.setPassword("123456");}@Testpublic void testLoginPasswordError() {//断言BusinessException e = Assertions.assertThrows(BusinessException.class, () -> {Employee employee = new Employee();employee.setUsername("admin");employee.setPassword("1234567");employeeController.login(employee);});//进一步断定更详细的异常类型Assertions.assertEquals("密码错误",e.getResponse().getMessage());}@Testpublic void testLoginUsernameError() {BusinessException e = Assertions.assertThrows(BusinessException.class, () -> {Employee employee = new Employee();employee.setUsername("adminaa");employee.setPassword("123456");employeeController.login(employee);});Assertions.assertEquals("用户不存在",e.getResponse().getMessage());}}

测试结果
