[英]Junit Test cases for Save and Update using Spring Boot REST
I've written a Test case to save & update which as below,我编写了一个测试用例来保存和更新,如下所示,
@InjectMocks
UserController uc;
@Mock
UserService userService;
@Mock
User user;
@Test
public void saveUser() throws Exception {
SimpleDateFormat simpleformat = new SimpleDateFormat("yyyy-MM-dd hh:mm:s+ss");
Long id= 2L;
String userName = "John";
String passWord = "john";
Date otpSentDate = simpleformat.parse("2019-12-24 01:22:05+00");
Date createdDate = simpleformat.parse("2019-12-24 01:22:05+00");
Date updatedDate = simpleformat.parse("2019-12-24 01:22:05+00");
user.setId(id);user.setUserName(userName);user.setPassWord(passWord);user.setOtpSentDate(otpSentDate);
user.setCreatedDate(createdDate);user.setUpdatedDate(updatedDate);
assertEquals(1, uc.saveUser(user));
}
@Test
public void updateUser() throws Exception {
SimpleDateFormat simpleformat = new SimpleDateFormat("yyyy-MM-dd hh:mm:s+ss");
Long id= 2L;
String userName = "John";
String passWord = "john";
Date otpSentDate = simpleformat.parse("2019-12-24 01:22:05+00");
Date createdDate = simpleformat.parse("2019-12-24 01:22:05+00");
Date updatedDate = simpleformat.parse("2019-12-24 01:22:05+00");
user.setId(id);user.setUserName(userName);user.setPassWord(passWord);user.setOtpSentDate(otpSentDate);
user.setCreatedDate(createdDate);user.setUpdatedDate(updatedDate);
assertEquals(1, uc.updateUser(user));
}
Controller for both methods are as below,两种方法的 Controller 如下,
@PostMapping("/saveUser")
public int saveUser(@RequestBody User user) throws Exception {
if (user.getUserName() == "" || user.getPassWord() == "") {
throw new Exception("User name or Password should not be empty!");
} else {
userService.saveUser(user);
System.out.println("Inserted data with id: "+ user.getId());
}
return 1;
}
@PutMapping("/updateUser")
public void updateUser(@RequestBody User user) {
userService.updateUser(user);
System.out.println("User with id "+ user.getId() + " updated successfully!");
}
And ServiceImpl.java are as follows,而ServiceImpl.java如下,
@Override
public void saveUser(User user) {
userMapper.saveUser(user);
}
@Override
public void updateUser(User user) {
userMapper.updateUser(user);
}
After running above methods, I'm getting error as below, org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.naveen.MybatisApplicationTests': Unsatisfied dependency expressed through field 'user';运行上述方法后,我收到如下错误,org.springframework.beans.factory.UnsatisfiedDependencyException: Error created bean with name 'com.naveen.MybatisApplicationTests': Unsatisfied dependency express through field 'user'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.naveen.entity.User' available: expected at least 1 bean which qualifies as autowire candidate.
嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException:没有“com.naveen.entity.User”类型的合格 bean 可用:预计至少有 1 个有资格作为自动装配候选者的 bean。
You test logic is wrong (:您的测试逻辑错误(:
You have userService as a Mock object - it won't return anything if you don't write it by yourself.您将 userService 作为 Mock object - 如果您不自己编写它,它将不会返回任何内容。 And it won't save in the db anything.
它不会在数据库中保存任何东西。 You can just verify calling this Mock:
您可以验证调用此 Mock:
then(userService).should(times(1)).saveUser(any(User.class));
And you don't need these rows:而且您不需要这些行:
SimpleDateFormat simpleformat = new SimpleDateFormat("yyyy-MM-dd hh:mm:s+ss");
Long id= 2L;
String userName = "John";
String passWord = "john";
Date otpSentDate = simpleformat.parse("2019-12-24 01:22:05+00");
Date createdDate = simpleformat.parse("2019-12-24 01:22:05+00");
Date updatedDate = simpleformat.parse("2019-12-24 01:22:05+00");
user.setId(id);user.setUserName(userName);user.setPassWord(passWord);user.setOtpSentDate(otpSentDate);
user.setCreatedDate(createdDate);user.setUpdatedDate(updatedDate);
because user is also a Mock object.因为用户也是模拟 object。
So your test will be something like that:所以你的测试将是这样的:
@Test
public void saveUser() throws Exception {
//given
given(user.getUserName()).willReturn("Username");
given(user.getPassWord()).willReturn("Password");
given(user.getId()).willReturn(1);
given(userService.saveUser(any(User.class))).willReturn(user);
//when
int result = uc.saveUser(user);
//then
then(userService).should(times(1)).saveUser(any(User.class));
assertEquals(1, result);
}
