Spring Boot Junit test injecting dao interface with constructor injection

Spring Boot Junit test injecting dao interface with constructor injection - java

Okay So I am trying to set up a springboot/junit test that tests a DAO that is injected to other classes via constructor injection.
Initially I tried constructor injection
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.autoconfigure.jdbc.AutoConfigureTestDatabase;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
import org.springframework.test.context.junit4.SpringRunner;
import com.portfolio.bork.webapp.services.db.ProjectDao;
#RunWith(SpringRunner.class)
#DataJpaTest
#AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
public class ProjectDaoTest {
ProjectDao projectDao;
#Test
public void getProject() {
assert projectDao.getProjectById(1L) != null;
}
public ProjectDaoTest() {}
public ProjectDaoTest(ProjectDao projectDao) {
this.projectDao = projectDao;
}
public void setProjectDao(ProjectDao projectDao) {
this.projectDao = projectDao;
}
}
but then get the error message
java.lang.IllegalArgumentException: Test class can only have one constructor
So then looked around and saw some options which boiled down to either using Junit 5(allows multiple constructors) or using Mockito to .
I would prefer to stick to whats in the spring-starter-test package. So I went with the mockito route. as such
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.junit.MockitoJUnitRunner;
import org.springframework.boot.test.autoconfigure.jdbc.AutoConfigureTestDatabase;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
// import org.springframework.test.context.junit4.SpringRunner;
import com.portfolio.bork.webapp.services.db.ProjectDao;
#RunWith(MockitoJUnitRunner.class)
#DataJpaTest
#AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
public class ProjectDaoTest {
#InjectMocks ProjectDao projectDao;
#Test
public void getProject() {
assert projectDao.getProjectById(1L) != null;
}
public ProjectDaoTest() {}
public void setProjectDao(ProjectDao projectDao) {
this.projectDao = projectDao;
}
}
But came across this issue,
org.mockito.exceptions.base.MockitoException:
Cannot instantiate #InjectMocks field named 'projectDao'! Cause: the type 'ProjectDao' is an interface.
You haven't provided the instance at field declaration so I tried to construct the instance.
Examples of correct usage of #InjectMocks:
#InjectMocks Service service = new Service();
#InjectMocks Service service;
//and... don't forget about some #Mocks for injection :)
If I try to mock the DAO implementation (which I am trying to avoid), I get an error
#InjectMocks ProjectDaoImpl projectDao;
// error
java.lang.NullPointerException at com.portfolio.bork.webapp.daotest.ProjectDaoTest.getProject(ProjectDaoTest.java:23)
Here is my DAO interface
public interface ProjectDao {
public Project getProjectById(Long projectId);
}
its implementation
package com.portfolio.bork.webapp.services.db;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import com.portfolio.bork.webapp.model.Project;
#Repository
public class ProjectDaoImpl implements ProjectDao {
#PersistenceContext
private EntityManager entityManager;
#Autowired
public ProjectDaoImpl() {}
public Project getProjectById(Long projectId) {
return entityManager.find(Project.class, projectId);
}
}
I utilize them as such in my Rest Controller
#RestController
public class ProjectRestController {
private ProjectDao projectDao;
...
// for constructor injection
public ProjectRestController(ProjectDao projectDao) {
this.projectDao = projectDao;
}
public void setProjectDao(ProjectDao projectDao) {
this.projectDao = projectDao;
}
}

Im somewhat new to different forms of dependency injection(other than autowiring fields) in Spring Boot, and new to unit testing as well.
And am using this application to poke with how Test code interacts with dependency injection, the source code and the test applicationContext.
I also would like to be able to not refer to the Dao Implementation code in the Test code.
Update:
If I try to autowire the setter, I get this error. I think my test is not picking up the source code application context?

As described in Auto-configured Data JPA Tests
You can use the #DataJpaTest annotation to test JPA applications. By default, it scans for #Entity classes and configures Spring Data JPA repositories. If an embedded database is available on the classpath, it configures one as well. Regular #Component beans are not loaded into the ApplicationContext.
Your repository in NOT a Spring Data repository, and hence is not loaded to the context
IMHO using a Spring Data repo (with custom methods if needed) is the way to go in your case.

I am writing test cases for my project using Junit5, when I run a test cases all the test cases passes, but some of them gives me below error in console

Below is how my pom looks like:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
<!-- exclude junit 4 -->
<exclusions>
<exclusion>

Below is how my test class looks like (provided necessary part of the class).
public class AccountServiceTest {
AccountService AccountService;
#Mock
ExportFile exportFile;
#BeforeEach
public void init() {
MockitoAnnotations.initMocks(this);
accountService = new AccountService(exportFile);
}
#Test
public void testFileExport() {
accountService.process(partner.getName());
Mockito.verify(exportFile).exportCsvFile(Mockito.anyList(), Mockito.anyString());
}
}

If you can upgrade your spring-boot-starter-test to at least 2.2.0.RELEASE it will bring you JUnit 5 (the exclusion is also not necessary if you want run JUnit4 and JUnit5 tests at the same time). Using only spring boot starter dependencies is a good way to handle incompatible version issue between dependencies as spring boot manages that for you.
If you want run a test with JUnit5 and Mockito, your class should look like this (the object you want to test is annotated with #InjectMocks and it's dependency you want mock with #Mock and the class test with #ExtendWith(MockitoExtension.class)) :
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;
#ExtendWith(MockitoExtension.class)
public class AccountServiceTest {
#Mock
ExportFile exportFile;
#InjectMocks
AccountService accountService;
#Test
public void testFileExport() {
accountService.process("");
Mockito.verify(exportFile).exportCsvFile(Mockito.anyList(), Mockito.anyString());
}
}

Why Spring Boot is not finding a #Service bean trying to perform autowiring? the bean exist but it can't find it

I am experiencing a strange problem working on a Spring Boot 2.2.5.RELEASE project that uses JUnit.
I try to explain my problem in details:
1) I defined a service. First I defined an interface named OrderService, like this:
package com.dgs.soc.service;
import java.util.List;
import com.dgs.soc.excelapi.dto.Order;
public interface OrderService {
public List<Order> getOrdersList();
}
Then I defined its implementation, at the moment something very simple named OrderServiceImpl:
package com.dgs.soc.service;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Service;
import com.dgs.soc.excelapi.dto.Order;
import com.dgs.soc.repository.OrderRepository;
#Service
public class OrderServiceImpl {
public List<Order> getOrdersList() {
List<Order> result = new ArrayList<Order>();
return result;
}
}
As you can see this class is annoted by the #Service annotation.
The problem is using JUnit, I have this test class:
package com.dgs.soc.excelapi.integration;
// IMPORTS LIST
#RunWith(SpringRunner.class)
#SpringBootTest(classes = { Application.class })
#WebAppConfiguration
#ActiveProfiles(profiles = { "no-liquibase" })
public class ExcelResourceIntegrationTest {
#Autowired
OrderServiceImpl orderService;
#Test
public void getOrdersListRepositoryTest() {
List<Order> ordersList = orderService.getOrdersList();
assertThat(ordersList).isNotEmpty();
}
}
And here I am experiencing a strange behavior: performing the getOrdersListRepositoryTest() test method I obtain this exception

It says that No qualifying bean of type 'com.dgs.soc.service.OrderServiceImpl' available but, as you can see in the prevuous code this bean exist and it is annoted by the #Service annotation to allow autowiring !!!
Into this project there is defined a class annotated by #RestController that exposes API. If into this class I try to autowire the same service class, something like this:
#Description(value = "Resource layer for handling REST requests.")
#RestController
#RequestMapping("api")
public class ExcelResource {
#Autowired
OrderServiceImpl orderService;
.......................................................
.......................................................
.......................................................
}
and now I try to perform the application as Spring Boot Application I obtain the same problem:
***************************
APPLICATION FAILED TO START
***************************
Description:
Field orderService in com.dgs.soc.excelapi.resources.ExcelResource required a bean of type 'com.dgs.soc.service.OrderServiceImpl' that could not be found.
The injection point has the following annotations:
- #org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'com.dgs.soc.service.OrderServiceImpl' in your configuration.
But again the com.dgs.soc.service.OrderServiceImpl bean exist and it is annotated by #Service.
Why am I obtaining this issue? What am I missing? How can I try to fix this problem? I was thinking that I have some references problem or something like this but I have no idea
EDIT-1:
Putting the #ComponentScan("com.dgs.soc.service") on the topo of my Application class it seems to work but I have some doubts !!!
So this is my Application class now:
package com.dgs.soc.excelapi;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
#SpringBootApplication
#ComponentScan("com.dgs.soc.service")
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Application.class);
}
}
It works but int thwory it should works also without the ** #ComponentScan("com.dgs.soc.service")** annotation because this class was annoted by #SpringBootApplication that as you can read here:
https://docs.spring.io/spring-boot/docs/2.1.12.RELEASE/reference/html/using-boot-using-springbootapplication-annotation.html
automatically enable #ComponentScan: #Component scan on the package where the application is located (see the best practices)
So the application is located into com.dgs.soc.excelapi and in theory I expected that the component scan have to work popperly also withot the explicit defntion of #ComponentScan
Why? Some idea?

The answer to your question is that you do not have proper package structure for spring-boot auto scan to pick up your service class.
SpringBootApplication annotation only enabled scanning of the package it resides in and its child packages.
If you have SpringBootApplication class in com.acme.app package then all the classes with spring boot annotation will get scanned in the package com.acme.app and any of its child packages i.e. com.acme.app.services, com.acme.app.controllers, etc. However if you have a package com.acme.services then any spring annotations are not auto-scanned from this package.
You have two options;
You either modify your package structure to allow spring-boot to auto scan all of the annotations. In your case move your Application class from com.dgs.soc.excelapi to com.dgs.soc. Or you could move all other packages i.e. service under com.dgs.soc.excelapi.
You explicitly list packages to scan using either #ComponentScan or scanBasePackages attribute on the SpringBootApplication annotation.

Try putting #ComponentScan annotation on top of main application class
#ComponentScan("base.package.name")

The problem is the following:
Your Application class is in package "com.dgs.soc.excelapi"
#SpringBootApplication scans that package + all its subpackages for #Services/#Components/#Repositories.
You put all your services in completely different packages though ("com.dgs.soc.service"), so Spring Boot won't find them. And hence the #ComponentScan annotation works.
Fix: Reorder your package structure.

get java.lang.ArrayStoreException on Springboot and ehcache

I have a method that calls a webservice and for same input arguments, I want the result to be cached. So, here is what i did so far:
The main class:
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.ehcache.EhCacheCacheManager;
import org.springframework.cache.ehcache.EhCacheManagerFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.core.io.ClassPathResource;
#EnableCaching
#ComponentScan
#SpringBootApplication
public class AccServer extends SpringBootServletInitializer {
#Bean
public CacheManager cacheManager() {
return new EhCacheCacheManager(ehCacheCacheManager().getObject());
}
#Bean
public EhCacheManagerFactoryBean ehCacheCacheManager() {
EhCacheManagerFactoryBean cmfb = new EhCacheManagerFactoryBean();
cmfb.setConfigLocation(new ClassPathResource("ehcache.xml"));
cmfb.setShared(true);
return cmfb;
}
}
Method to cache:
import java.util.List;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Service;
#Service
public class SomeClass implements ISomeClass {
#Override
#Cacheable("acc")
public List<Integer> trs() {
return webSrv.trs();
}
}
ehcache.xml
<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd" updateCheck="false">
<diskStore path="java.io.tmpdir" />
<cache name="acc" maxElementsInMemory="100" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" maxElementsOnDisk="10000000" diskPersistent="false" diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU" />
</ehcache>
And I get:

I also use #Cacheable("acc") annotation for the method which should be cached for the result.
Any answers would be appreciated.

The issue is with the #Cacheable trs() method (of your #Service SomeClass class) which is NOT returning List<Integer> object because of which you are getting sun.reflect.annotation.TypeNotPresentExceptionProxy exception.
You need to ensure that trs() is returning the List<Integer> object.

Thanks to fellows how contributed on this question, finally after long time of debugging, I just found that there is need for excluding two dependencies from project, so that it becomes:
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-actuator</artifactId>
</exclusion>
<exclusion>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</exclusion>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</exclusion>

That exception means something attempted to do a lookup on an annotation that's not present on the classpath. Unfortunately, the JDK isn't telling us much about it but I think we've improved the error message in recent version of the framework (and therefore boot).
You could also add a breakpoint in the faulty code and it will tell you what it's trying to resolve. That should give you a hint of what the missing annotation is. Most of the time, this isn't strictly related to the component that does the lookup (i.e. it might very well be unrelated to caching). If you share a sample app, we could easily figure it out.

But most weird, is if I remove spring-context dependency then test is passing well, but controller getting different error, that he couldn't autowired some beans.
I'm new to Spring data, and spring mvc. I know how to write entities, controllers, and ropositories class, but I still have problem with configuration. Do you know why test works after removing that dependency, and why not working with it? And finally how to make it works all together?

Maybe in intellij there is such a tree:
How to read such a tree? You will notice there is ehcache-spring-annotation (4th from bottom) requiring a previous version of slf4j-api (3rd from bottom in version 1.6.2). But a newer version of slf4j-api is hardcoded(1st from above).
Now, when slf4j in example having a method clearMetadataCache in version 1.6.1 that is removed in 1.6.6, such a NoSuchMethodError is thrown.

As the error log said Spring failed to autowire MeetingController because it cannot autowird MeetingRepository. So check the MeetingRepository implementation if you have added #Repository to make sure the Spring can autowire it, or make sure the Spring will scan the component package.

You should consider using the Spring IO Platform, that should resolve the version issues regarding the spring dependencies.
For details see enter link description here .
Additionally either use spring-data-jpa or don't use it. I would use it, the spring-data repsitories are really simple and powerfull. The EntityManager dependency is in that case not necessary.

Why is this Spring test trying to autowire beans it should not be able to see?

Here's my project structure:
Here's my SubjectTest:
package com.sandbox.autowireintest;
import com.sandbox.autowireintest.configuration.TestConfig;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import static org.junit.Assert.*;
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(classes = {TestConfig.class})
public class SubjectTest {
#Autowired
Subject subject;
#Test
public void testName() throws Exception {
}
}
Here's the TestConfig:
package com.sandbox.autowireintest.configuration;
import com.sandbox.autowireintest.AutowireInTest;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import static org.mockito.Mockito.mock;
#Configuration
public class TestConfig {
#Bean
public AutowireInTest autowireInTest() {
return mock(AutowireInTest.class);
}
}
This test fails on startup with this error:

I don't understand why I'm getting this error. Subject autowires AutowireInTest. AutowireInTest autowires IgnoreInTest, but I'm assuming the TestConfig should overwrite AutowireInTest and replace it with a mock that does not have the autowire to IgnoreInTest. So why does this test still start with this error?
My goal is to avoid using a real AutowireInTest in my test and context, but I do have other autowired classes in my Subject (not in this code, but in my real code I'm trying to test) that I do want to autowire. How do I achieve this?
If anything, I would expect this test to fail saying it can't find Subject. My TestConfig only has a #Bean for AutowireInTest, so how does my test know how to autowire Subject? I haven't told it to scan anything.

A mock object is an instance of a dynamically created class that extends the class being mocked. The class being mocked has fields annotated with #Autowired. So Spring is supposed to autowire these fields. But it can't because the beans to autowire don't exist, hence the exception.
There is no reason to load a Spring context to implement a unit test. Just use Mockito without Spring:
#InjectMocks
private Subject subject;
#Mock
private AutowireInTest mockAutowizeInTest;
#Before
public void prepare() {
MockitoAnnotations.initMocks(this);
}
Iy fou used constructor injection, the problem you're facing would become obvious, because the dependencies wouldbe explicit, and you wouldn't need the annotation support of Mockito:
AutowireInTest mockAutowireInTest = mock(AutowireInTest.class);
Subject subject = new Subject(mockAutowireInTest);
Regarding your second question: the est would fail later if it went until there. But it can't go until there because it can't even create the beans referenced in the context.

Why Spring Boot is not finding a #Service bean trying to perform autowiring? the bean exist but it can't find it

get java.lang.ArrayStoreException on Springboot and ehcache

Dependencies not working well

Why is this Spring test trying to autowire beans it should not be able to see?
