How to properly run all Junit tests in Spring without a db connection

Hi friends hope you are doing well.
So I was writing some simple unit tests for my simple project and I as soon as started to run the tests, I faced some problem.
First of all there are the tests code :
GetAllUsersServiceTest.java
package com.challenge.simpleApi.domains.users.services.getAllUsersService;
import com.challenge.simpleApi.domains.users.models.Users;
import com.challenge.simpleApi.domains.users.repositories.UsersRepository;
import java.util.ArrayList;
import java.util.List;
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.junit.jupiter.MockitoExtension;
import org.springframework.boot.jdbc.EmbeddedDatabaseConnection;
import org.springframework.boot.test.autoconfigure.jdbc.AutoConfigureTestDatabase;
import org.springframework.boot.test.context.SpringBootTest;
#ExtendWith(MockitoExtension.class)
public class GetAllUsersServiceTest {
#Mock
private UsersRepository usersRepository;
#InjectMocks
private GetAllUsersService getAllUsersService;
private List<Users> fakeRepositoryReturn = new ArrayList<Users>();
final Users user1 = new Users(1L, "John", 28, null);
final Users user2 = new Users(2L, "Peter", 20, null);
final Users user3 = new Users(3L, "Patricia", 21, null);
#BeforeEach
void setUp() {
fakeRepositoryReturn.add(user1);
fakeRepositoryReturn.add(user2);
fakeRepositoryReturn.add(user3);
}
#Test
#DisplayName("Should be able to return all Users")
void ShouldReturnAllUsers() {
Mockito.when(usersRepository.findAll()).thenReturn(fakeRepositoryReturn);
List<Users> actual = getAllUsersService.execute();
Assertions.assertEquals(fakeRepositoryReturn, actual);
}
}
CreateUsersServiceTest.java
package com.challenge.simpleApi.domains.users.services.CreateUsersService;
import com.challenge.simpleApi.domains.users.models.Users;
import com.challenge.simpleApi.domains.users.repositories.UsersRepository;
import java.util.ArrayList;
import java.util.List;
import java.util.Set;
import java.util.stream.Collectors;
import javax.validation.ConstraintViolation;
import javax.validation.Validation;
import javax.validation.Validator;
import javax.validation.ValidatorFactory;
import org.junit.jupiter.api.*;
import org.junit.jupiter.api.extension.ExtendWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.junit.jupiter.MockitoExtension;
import org.springframework.boot.jdbc.EmbeddedDatabaseConnection;
import org.springframework.boot.test.autoconfigure.jdbc.AutoConfigureTestDatabase;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.web.bind.MethodArgumentNotValidException;
//#SpringBootTest
//#AutoConfigureTestDatabase(connection = EmbeddedDatabaseConnection.H2)
#ExtendWith(MockitoExtension.class)
public class CreateUsersServiceTest {
#Mock
private UsersRepository usersRepository;
#InjectMocks
private CreateUsersService createUsersService;
//Validator Instances - Used to validate the annotations inside the entities
private static ValidatorFactory validatorFactory;
private static Validator validator;
#BeforeEach
void setUp() {}
#BeforeAll
static void beforeAll() {
//Instantiate the validators
validatorFactory = Validation.buildDefaultValidatorFactory();
validator = validatorFactory.getValidator();
}
#AfterAll
static void afterAll() {
validatorFactory.close();
}
#Test
#DisplayName("Should be able to create a new User")
void createUserTest() {
Users userInput = new Users(null, "Jonas", 28, null);
Users expected = new Users(1L, "Jonas", 28, null);
Mockito.when(usersRepository.save(userInput)).thenReturn(expected);
Users actual = createUsersService.execute(userInput);
Assertions.assertEquals(expected, actual);
}
#Test
#DisplayName("Should not be able to create a new User without a name")
void CreateUserWithoutNameTet() {
Users userInput = new Users(null, null, 18, null);
Set<ConstraintViolation<Users>> violations = validator.validate(userInput);
List<String> errors = new ArrayList<String>();
errors =
violations.stream().map(x -> x.getMessage()).collect(Collectors.toList());
Assertions.assertEquals("Name should not be empty", errors.get(0));
}
#Test
#DisplayName("Should not be able to create a new under 18yo User")
void CreateUnder18User() {
Users userInput = new Users(null, "Paull", 17, null);
var errors = validator
.validate(userInput)
.stream()
.map(x -> x.getMessage())
.collect(Collectors.toList());
Assertions.assertEquals("Should not be less than 18", errors.get(0));
}
}
As you noticed, my unit tests don't need an database to run(To be honest it doesn't make any sense to have it at all) I even mocked the repository. When I run them individually, they run pretty good
mvn test -Dtest=GetAllUsersServiceTest
mvn test -Dtest=CreateUsersServiceTest
However When I run them all, my tests get messed up :
mvn test
And it looks like it's trying to connect to a database. Honestly I couldn't find how can I change this behavior. They run pretty good individually, however when I run them all ta once, things start to be strange.
If you guys could help me understand what's going wrong, I Would be thankfull
Thanks in advance

Thank you in advance! :)

This answer is originally posted by #deadpool in the comments.
Spring Initializr creates an example test class in the test package. This class has the #SpringBootTest annotation.
This annotation ensures a complete Spring boot environment is loaded within the test, requiring a connection.
The solution to this case is remove the annotation, or remove the java file itself.

Spring Boot 2 - Unsatisfied dependency on Feign client when autowired for service

I have a pretty simple situation and I've tried a few things now and I can't find the cause of this issue. It claims it can not Autowire the Feign client class though this is how I have done this in Spring Boot 1.5.9. At least I'm pretty sure. Things work fine in all my unit tests though I'm mocking this client. Formerly it was a part of an imported library however to eliminate possibilities of me not properly locating the bean I just added it to the same project.
I'm not the most experienced with Spring or Feign so I'm wondering if it's obvious what I'm missing here.
Simple feign client:
#FeignClient(name = "my-other-service")
public interface OtherServiceClient {
#GetMapping(value = "/foo/{fooId}")
#ResponseBody
String getFoo(#PathVariable int fooId);
}
Main application class:
#SpringBootApplication
#EnableDiscoveryClient
#EnableFeignClients
// Had a component scan here when in other module
public class MyServiceApplication {
public static void main(String[] args) {
SpringApplication.run(MyServiceApplication.class, args);
}
}
The service that depends on the feign client:
#Service
public class FooService {
private final FooRepository fooRepository;
private final BarRepository barRepository;
private OtherServiceClient otherServiceClient;
#Autowired
public OrderService(
FooRepository fooRepository,
BarRepository barRepository,
OtherServiceClient otherServiceClient) {
this.fooRepository= fooRepository;
this.barRepository = barRepository;
this.otherServiceClient = otherServiceClient;
}
Since it might be an auto config thing here is the configuration report:

I'm pretty stumped at this point.
EDIT:
Update, so, in order to investigate more as I was confident the service started prior to beginning the Feign work I commented out all references to the feign client and the feign client itself except the the configuration annotations on the application class. I still see the reference to the database driver on start up but the application does indeed run. This is the exception I see on start up but without Feign interactions the application starts.

The database driver is on the older side so I might see about updating it to the ojdbc8 driver maybe while I'm at it...

There was an issue in feign client before. I guess you are experiencing the same maybe because you are using an old version but what you should do is including the pathVariable name in your #PathVariable annotation like this
#RequestMapping(value = "/hello/{name}", method = RequestMethod.GET)
String hello(#PathVariable(value = "name") String name);
You can find the details from here

When you using rest feign client service we need to define exact #Pathvariable name.
#GetMapping("/hello-world/from/{from}/to/{to}")
public String getHelloWorld(#PathVariable("from") String from, #PathVariable ("to") String to);

I had the same issue with #pathvariable, its resolved when I added the value property of #PathVariable like below,
#PathVariable(value = "from") String from,
#PathVariable(value = "to") String to);

#GetMapping(value = "/foo/{fooId}")
#ResponseBody
String getFoo(#PathVariable(value="fooId") int fooId);
will do

package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
#SpringBootApplication
#ComponentScan("com.example.demo")
public class AppConfig extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(AppConfig.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(AppConfig.class, args);
}
}
I use spring boot and resolver jstl. My version spring boot is 1.5.3 RELEASE.
spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp
What could be wrong?

Change main method like this.
#SpringBootApplication
#ComponentScan("com.example.demo")
public class AppConfig {
public static void main(String[] args) throws Exception {
SpringApplication.run(AppConfig.class, args);
}}

I have also faced with the same issue and the root cause was related to missing dependency. The issue was not related to Spring boot starter. So, I have simply tried to add one more dependency which can work fine with your JSTL
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
</dependency>

Spring service will not start

Working on a basic Spring REST service, but I seem to have a problem with running the service due to JDBC.
I have followed a simple tutorial, but at the end the following error log comes up.

The code in the tutorial you are following is not using Spring Boot, yet you are for some reason. SpringApplication.run creates its own application context, which might be the source of your problems. Either use Spring Boot and don't create the application context manually or create it manually as illustrated in the tutorial and don't use Spring Boot.
If you wish to use Spring Boot, you should modify your code like this:
1) Remove the manual application context creation from your main class
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
2) Define your data source using Spring boot properties file (src/main/resources/application.properties) and get rid of Beans.xml:
spring.datasource.url=jdbc:mysql://localhost:3306/fenrir_customers
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
3) Modify your CustomerJDBCTemplate like this:
#Repository
public class CustomerJDBCTemplate implements CustomerDAO {
#Autowired
private JdbcTemplate jdbcTemplate;
// Rest of your methods
}
4) Autowire the repository in the controller, don't manually create it:
#RestController
public class CustomerController {
#Autowired
private CustomerDAO customerDao;
// Controller methods ...
}
5) Adjust your dependencies
Remove
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>4.2.1.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>4.2.1.RELEASE</version>
</dependency>
and add
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>

What I've tried so far:
Accessing the URL with the application name (InventoryApp)
Put another #RequestMapping("/") at class level of the ItemInventoryController
As far as I understood, I won't need an application-context when using Spring Boot. Am I right?
What else can I do to access the method via URL?

Try adding the following to your InventoryApp class
#SpringBootApplication
#ComponentScan(basePackageClasses = ItemInventoryController.class)
public class InventoryApp {
...
spring-boot will scan for components in packages below com.nice.application, so if your controller is in com.nice.controller you need to scan for it explicitly.

Adding to MattR's answer:
As stated in here, #SpringBootApplication automatically inserts the needed annotations: #Configuration, #EnableAutoConfiguration, and also #ComponentScan; however, the #ComponentScan will only look for the components in the same package as the App, in this case your com.nice.application, whereas your controller resides in com.nice.controller. That's why you get 404 because the App didn't find the controller in the application package.

Same 404 response I got after service executed with the below code
#Controller
#RequestMapping("/duecreate/v1.0")
public class DueCreateController {
}
Response:
{
"timestamp": 1529692263422,
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/duecreate/v1.0/status"
}
after changing it to below code I received proper response
#RestController
#RequestMapping("/duecreate/v1.0")
public class DueCreateController {
}
Response:
{
"batchId": "DUE1529673844630",
"batchType": null,
"executionDate": null,
"status": "OPEN"
}

SpringBoot developers recommend to locate your main application class in a root package above other classes. Using a root package also allows the #ComponentScan annotation to be used without needing to specify a basePackage attribute. Detailed info
But be sure that the custom root package exists.

There are 2 method to overcome this
Place the bootup application at start of the package structure and rest all controller inside it.
Example :
package com.spring.boot.app; - You bootup application(i.e. Main Method -SpringApplication.run(App.class, args);)
You Rest Controller in with the same package structure
Example :
package com.spring.boot.app.rest;
Explicitly define the Controller in the Bootup package.
Method 1 is more cleaner.

I had this issue and what you need to do is fix your packages. If you downloaded this project from http://start.spring.io/ then you have your main class in some package. For example if the package for the main class is: "com.example" then and your controller must be in package: "com.example.controller". Hope this helps.

The controller should be accessible in the same namespace
This is what you have
This is how it should be, see the hierarchy of the namespace

You need to modify the Starter-Application class as shown below.
#SpringBootApplication
#EnableAutoConfiguration
#ComponentScan(basePackages="com.nice.application")
#EnableJpaRepositories("com.spring.app.repository")
public class InventoryApp extends SpringBootServletInitializer {..........
And update the Controller, Service and Repository packages structure as I mentioned below.
Example:
REST-Controller
package com.nice.controller; --> It has to be modified as
package com.nice.application.controller;
You need to follow proper package structure for all packages which are in Spring Boot MVC flow.
So, If you modify your project bundle package structures correctly then your spring boot app will work correctly.

Replace #RequestMapping( "/item" ) with #GetMapping(value="/item", produces=MediaType.APPLICATION_JSON_VALUE).
Maybe it will help somebody.

for me, I was adding spring-web instead of the spring-boot-starter-web into my pom.xml
when i replace it from spring-web to spring-boot-starter-web, all maping is shown in the console log.

I had exact same error, I was not giving base package. Giving correct base package,ressolved it.
package com.ymc.backend.ymcbe;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
#SpringBootApplication
#ComponentScan(basePackages="com.ymc.backend")
public class YmcbeApplication {
public static void main(String[] args) {
SpringApplication.run(YmcbeApplication.class, args);
}
}
Note: not including .controller
#ComponentScan(basePackages="com.ymc.backend.controller") because i
have many other component classes which my project does not scan if i
just give .controller
Here is my controller sample:
package com.ymc.backend.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
#CrossOrigin
#RequestMapping(value = "/user")
public class UserController {
#PostMapping("/sendOTP")
public String sendOTP() {
return "OTP sent";
};
}

I found a really great thread for this issue.
https://coderanch.com/t/735307/frameworks/Spring-boot-Rest-api
The controller api should be in the sub directory structure to automatically detect the controllers. Otherwise annotation argument can be used.
#SpringBootApplication(scanBasePackages = {"com.example.demo", "com.example.Controller"})

New to Springboot, tried everything above, but ended up being as simple as I had a / at the end of the URL on my browser while my only Get() method was blank, just returning a string.
Hope this'll help someone someday.

Sometimes spring boot behaves weird. I specified below in application class and it works:
#ComponentScan("com.seic.deliveryautomation.controller")

I got the 404 problem, because of Url Case Sensitivity.
For example
#RequestMapping(value = "/api/getEmployeeData",method = RequestMethod.GET) should be accessed using http://www.example.com/api/getEmployeeData. If we are using http://www.example.com/api/getemployeedata, we'll get the 404 error.
Note:
http://www.example.com is just for reference which i mentioned above. It should be your domain name where you hosted your application.
After a lot of struggle and apply all the other answers in this post, I got that the problem is with that url only. It might be silly problem. But it cost my 2 hours. So I hope it will help someone.

It also works if we use as follows:
#SpringBootApplication(scanBasePackages = { "<class ItemInventoryController package >.*" })

It could be that something else is running on port 8080, and you're actually connecting to it by mistake.
Definitely check that out, especially if you have dockers that are bringing up other services you don't control, and are port forwarding those services.

The problem is with your package structure. Spring Boot Application has a specific package structure to allow spring context to scan and load various beans in its context.
In com.nice.application is where your Main Class is and in com.nice.controller, you have your controller classes.
Move your com.nice.controller package into com.nice.application so that Spring can access your beans.

Another solution in case it helps: in my case, the problem was that I had a #RequestMapping("/xxx") at class level (in my controller), and in the exposed services I had #PostMapping (value = "/yyyy") and #GetMapping (value = "/zzz"); once I commented the #RequestMapping("/xxx") and managed all at method level, worked like a charm.

For me, the problem was that I had set up the Application in a way that it always immediately shut down after starting. So by the time I tried out if I could access the controller, the Application wasn't running anymore.
The problem with immediately shutting down is adressed in this thread.

#SpringBootApplication
#ComponentScan(basePackages = {"com.rest"}) // basePackageClasses = HelloController.class)
// use above componnent scan to add packages
public class RestfulWebServicesApplication {
public static void main(String[] args) {
SpringApplication.run(RestfulWebServicesApplication.class, args);
}
}

There may 3 reasons causing for this error:
1>
check your URL you are requesting is correct
2> check if your
using MVC then use #Controller else use #RestController
3> check
whether you have placed Controller package(or Class) outside the root
package example: com.example.demo -> is your main
package
place controller package inside com.example.demo.controller

I had the same issue, because I created an inner class annotated with #Configuration and it prohibited somehow the component scan.

I had the same problem, and while the above solution are correct in their own right, they did not work for me, and I found another possible reason that solved it - you have to shut down the application from the port, and restart your application, if doing a Maven Update or a project clean fail to solve it.
Briefly, open a command prompt, and run the following two commands:
netstat -ano | findstr :8080
This command will locate the Process ID that is attached at the port that your app is running on - please make sure to specify the port, if you have it anywhere other than the default.
You will get the following output:
What you care about is the number in the last column, which is the process ID associated with the port, on which the instance of the app is running.
If you are using STS4 for your development purposes, you can also see the PID on the top margin of the console, but you do have to squint for it:
At this point, run the next command to kill the process:
taskkill /pid 22552 /f
And it results in this:
Do remember that there will be a different PID for every time you run the application.
And finally, you can run it again, and that should do it.

Programmatically shutting down SpringBoot app

Change the Return type from String to ResponseEntity
Like :
#RequestMapping( "/item" )
public ResponseEntity<String> getStockItem() {
return new ResponseEntity<String>("It's working...!", HttpStatus.OK);
}

Place your springbootapplication class in root package for example if your service,controller is in springBoot.xyz package then your main class should be in springBoot package otherwise it will not scan below packages

You can add inside the POM.
