How to use mockito with maven testing harness - java

The maven plugin I am developing now injects some dependencies using Google Guice with JSR-330. For unit testing I am using maven-plugin-testing-harness. The plugin works perfectly. But there is a problem with tests. I want to inject mocked components into mojo, but still there are real objects in tests.
I've tried to write my custom test module as it's said in Google Guice Bound Field, but it didn't work. After some debugging I found out that Plexus container doesn't allow to use custom modules.
There are my mojo:
package my.maven.plugins.myplugin;
import my.maven.plugins.myplugin.component.MyComponent;
import org.apache.maven.plugin.AbstractMojo;
import org.apache.maven.plugins.annotations.Mojo;
import org.apache.maven.plugins.annotations.Parameter;
import org.apache.maven.project.MavenProject;
import javax.inject.Inject;
#Mojo(name = "resolve-property-value")
public class MyMojo extends AbstractMojo {
private final MyComponent component;
#Parameter(readonly = true, defaultValue = "${project}" )
private MavenProject project;
#Inject
public MyMojo(MyComponent component) {
this.component = component;
}
#Override
public void execute() {
String value = component.resolvePropertyValue();
project.getProperties().setProperty("some.property", value);
}
}
Component's interface:
package my.maven.plugins.myplugin.component;
public interface MyComponent {
String resolvePropertyValue();
}
And implementation
package my.maven.plugins.myplugin.component.impl;
import my.maven.plugins.myplugin.component.MyComponent;
import javax.inject.Named;
#Named
public class MyComponentImpl implements MyComponent {
#Override
public String resolvePropertyValue() {
return "someValue";
}
}
Test:
package my.maven.plugins.myplugin;
import my.maven.plugins.myplugin.component.MyComponent;
import org.apache.maven.plugin.Mojo;
import org.apache.maven.plugin.testing.MojoRule;
import org.apache.maven.project.MavenProject;
import org.junit.Before;
import org.junit.Rule;
import org.junit.Test;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;
import java.util.Properties;
import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertTrue;
import static org.mockito.Mockito.doReturn;
public class MyMojoTest {
#Mock
private MyComponent component;
#Rule
public MojoRule mojoRule = new MojoRule();
#Before
public void setUp() {
MockitoAnnotations.initMocks(this);
}
#Test
public void should_set_some_property() throws Exception {
doReturn("testValue").when(component).resolvePropertyValue();
MavenProject project = new MavenProject();
Mojo goal = mojoRule.lookupConfiguredMojo(project, "resolve-property-value");
goal.execute();
Properties properties = project.getProperties();
assertTrue(properties.containsKey("some.property"));
assertEquals("testValue", properties.get("some.property"));
}
}

Is there any way to use mockito in plugin unit tests?

I suppose there is no "magic" ways to inject mocked components. So I've decided to put it into container explicitly in setUp section
#Before
public void setUp() {
MockitoAnnotations.initMocks(this);
mojoRule.getContainer().addComponent(component, MyComponent.class, "");
}

Avoid aspects overriding in AspectJ

I have two different aspects in my Selenium test automation project and I am using load time weaving with AspectJ. Both aspects run fine when running under test methods in that class.
The case where AspectA running on #Before("#annotation(ChangeToIFrameA)") on a method1 that is under a method0 that is already annotated with #Before class it overrides the second aspect call AspectB on method2 that is called under method1.
Aspect A class
package com.stackoverfow.FrameHandling;
#Aspect
public class AspectA {
#Before("#annotation(com.stackoverfow.FrameHandling.ChangeToIFrameA)")
public void switchIFrameA(WebDriver driver)) {
driver.switchTo().frame("IFrameA name");
}
}
Custom Annotated class for Aspect A to run
package com.stackoverfow.FrameHandling;
#Target(ElementType.METHOD)
#Retention(RetentionPolicy.RUNTIME)
#Documented
public #interface ChangeToIFrameA {
}
Aspect B class
package com.stackoverfow.FrameHandling;
#Aspect
public class AspectB {
#Before("execution(com.stackoverfow.NavigationBar.*(..))")
public void switchIFrameB(WebDriver driver)) {
driver.switchTo().frame("IFrameB name");
}
#After("execution(com.stackoverfow.NavigationBar.*(..))")
public void switchIFrameA(WebDriver driver)) {
driver.switchTo().frame("IFrameA name");
}
}
Navigation Bar Class
package com.stackoverfow.Navigation;
class NavigationBar{
class NavigationBar(){}
public void goToHomePage(){
//Navigates to Home Page
}
public void goToHelpPage(){
//Navigates to Help Page
}
public void goToUserAccount(){
//Navigates to User Account Page
}
}
Test Class that uses TestNG
package com.stackoverfow.NavigationTests;
public class AppBasicTests {
#BeforeClass(alwaysRun = true)
public void login(ITestContext context) {
//logs into the application
takeCareOfNavigationToHomePage();
}
#BeforeMethod(alwaysRun = true)
public void openSecondTab(ITestContext context) {
//Open a new tab
}
#AfterMethod(alwaysRun = true)
public void closeSecondTab() {
//closes the secondary tab
}
#AfterClass(alwaysRun = true)
public void logout() {
//logs out from the app
}
//Annotated to private method that is called inside login() method which is annotated by #Before class
#ChangeToIFrameA
private void takeCareOfNavigationToHomePage(){
NavigationBar navigationBar = new NavigationBar();
navigationBar.goToHomePage();// Assuming AspectB runs before and after this method call for switching frames
}
//Assuming it switches to FrameA before running the test
#ChangeToIFrameA
#Test(enabled = true)
public void testNavigation(){
NavigationBar navigationBar = new NavigationBar();
navigationBar.goToHelpPage();// Assuming AspectB runs
before and after this method call for switching frames
}
}

Here AspectA runs fine on method testNavigation()
AspectB runs fine on inner method call of NavigationBar.goToHelpPage() that is present under testNavigation() method.
When private method takeCareOfNavigationToHomePage() that is annotated #ChangeToIFrameA is called AspectA runs on that method and during the inner method call NavigationBar.goToHomePage() again AspectA is called instead of AspectB. AspectA call happens twice looks like an overriding is happen.
I see its happening because the private method takeCareOfNavigationToHomePage is called under login method that is already annotated with TestNG annotation #BeforeClass. Any idea how to overcome this? Please suggest a solution.

#MicronautTest - limit what is instantiated

Whenever I used #MicronautTest in my project, the whole application is started as a whole and because certain things need to be done at startup by services, they are executed also.
I don't need the whole Singleton shebang when I'm testing a simple controller.
My question is how do I limit which controllers and singletons are loaded when testing Micronaut?
I have a small demo example which shows the problem

application.java
package com.example;
import io.micronaut.runtime.Micronaut;
public class Application {
public static void main(String[] args) {
Micronaut.run(Application.class, args);
}
}
A simple service that throws whenever it is instantiated to indicate the problem
#Singleton
public class SingletonService {
#EventListener
public void init(ApplicationStartupEvent event) {
throw new RuntimeException("I was initialized");
}
}
A simple controller
#Controller
public class TestController {
#Get
public Simple findAll() {
return new Simple("ATest");
}
public static class Simple {
private final String test;
public Simple(String test) {
this.test = test;
}
public String getTest() {
return test;
}
}
}
And a straightforward test
#MicronautTest
class TestControllerTest {
#Inject
#Client("/")
RxHttpClient rxHttpClient;
#Test
void controller() {
HttpResponse<ByteBuffer> byteBufferHttpResponse = rxHttpClient.exchange("/").blockingFirst();
assert byteBufferHttpResponse.getStatus().getCode() == 200;
}
}
The test results are
[INFO] Running com.example.controller.TestControllerTest
11:01:52.804 [main] INFO i.m.context.env.DefaultEnvironment - Established active environments: [test]
[ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 7.232 s <<< FAILURE! - in com.example.controller.TestControllerTest
[ERROR] com.example.controller.TestControllerTest Time elapsed: 7.229 s <<< ERROR!
java.lang.RuntimeException: I was initialized
How do I prevent the test from starting that SingletonService? Stubbing is an option but keep in mind that this is a simple demo illustrating the issue for a bigger project. Is there no other straightforward way?
According to the docs of #MicronautTest, it shouldn't be scanning the classpath but it clearly is?
Here are some other configurations I've already attempted without any success:
Adding a ApplicationBuilder that disables eagerInit
#MicronautTest(application = TestControllerTest.TestApplication.class)
class TestControllerTest {
public static class TestApplication {
public static void main(String[] args) {
Micronaut.build(args)
.eagerInitAnnotated(null)
.eagerInitSingletons(false)
.mainClass(TestApplication.class);
}
}
#Inject
#Client("/")
RxHttpClient rxHttpClient;
#Test
void controller() {
HttpResponse<ByteBuffer> byteBufferHttpResponse = rxHttpClient.exchange("/").blockingFirst();
assert byteBufferHttpResponse.getStatus().getCode() == 200;
}
}
Passing along a contextbuilder
#MicronautTest(contextBuilder = TestControllerTest.TestContextBuilder.class)
class TestControllerTest {
public static class TestContextBuilder extends DefaultApplicationContextBuilder {
public TestContextBuilder() {
eagerInitSingletons(false);
eagerInitAnnotated(null);
eagerInitConfiguration(false);
}
}
#Inject
#Client("/")
RxHttpClient rxHttpClient;
#Test
void controller() {
HttpResponse<ByteBuffer> byteBufferHttpResponse = rxHttpClient.exchange("/").blockingFirst();
assert byteBufferHttpResponse.getStatus().getCode() == 200;
}
}
Which all yield the same response.
Hopefully someone knows how to limit the scope of bean instantation with the #MicronautTest or I'll most likely switch back to Spring boot
Thanks in advance
My question is how do I limit which controllers and singletons are
loaded when testing Micronaut?
At least there is the #Requires annotation that allows doing flexible configuration if a bean should be loaded within the current environment.
For example, in your case it should be something like:
import javax.inject.Singleton;
import io.micronaut.context.annotation.Requires;
#Singleton
#Requires(notEnv = {Environment.TEST})
public class SingletonService {
#EventListener
public void init(ApplicationStartupEvent event) {
throw new RuntimeException("I was initialized");
}
}
As a result, the exception from the service is not thrown.
However, I don't really know the purpose why you need to exclude the service. And it could be that other approaches might be more convenient.
For example, see Mocking Collaborators section from the micronaut test documentation: https://micronaut-projects.github.io/micronaut-test/latest/guide/

Problem with spring boot annotation autowired

I have the following problem. I trying to start a Spring Boot application with the DB2 database with Hybernate. So i created a repository and used the #Autowired annotation to get some data from the DB. The problem is that when I run the application i receive the following error:
***************************
APPLICATION FAILED TO START
***************************
Description:
Field studenteRepository in com.ibm.snam.ai4legal.controller.HelloWorldController required a bean of type 'com.ibm.snam.ai4legal.repositories.StudenteRepository' that could not be found.
Action:
Consider defining a bean of type 'com.ibm.snam.ai4legal.repositories.StudenteRepository' in your configuration.
Here are the classes of the application
Application class:
package com.ibm.snam.ai4legal.application;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication(scanBasePackages = {"com.ibm"})
public class SBApplication {
public static void main(String[] args) {
SpringApplication.run(SBApplication.class, args);
}
}
Repository class:
package com.ibm.snam.ai4legal.repositories;
import org.springframework.data.repository.CrudRepository;
import com.ibm.snam.ai4legal.model.Studente;
public interface StudenteRepository extends CrudRepository<Studente, Integer>{
}
Model class:
package com.ibm.snam.ai4legal.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
#Entity
public class Studente{
#Id
#GeneratedValue
private int id;
private String nome;
private String cognome;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getnome() {
return nome;
}
public void setnome(String nome) {
this.nome = nome;
}
public String getcognome() {
return cognome;
}
public void setcognome(String cognome) {
this.cognome = cognome;
}
}
Controller class:
package com.ibm.snam.ai4legal.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;
import com.ibm.snam.ai4legal.repositories.StudenteRepository;
#RestController
public class HelloWorldController {
#Autowired
StudenteRepository studenteRepository;
#GetMapping(value = "/home")
public ModelAndView helloworld() {

On the internet I found that I should insert <context:annotation-config/> in some configuration file but I have no idea in which file I have to put it. Someone can help?
You have to use #ComponentScan annotation. Try the below code.
#ComponentScan({"com.ibm.*"})
#SpringBootApplication
public class SBApplication {
public static void main(String[] args) {
SpringApplication.run(SBApplication.class, args);
}
}
Also mention #Repository annotation in StudenteRepository class.
Either move SBApplication to com.ibm.snam.ai4legal package so it can benefit from default component scanning or add the following annotations to specify packages to be scanned for entities and repositories.
#SpringBootApplication(scanBasePackages = {"com.ibm"})
#EnableJpaRepositories(basePackages = {"com.ibm"})
#EntityScan(basePackages = {"com.ibm"})
public class SBApplication {
public static void main(String[] args) {
SpringApplication.run(SBApplication.class, args);
}
}
Since you are using spring-boot-starter-data-jpa you need to provide the annotation #EnableJpaRepositories to tell springboot to autoconfigure everything.So you might want to use the auto configuration feature of springboot.The #EnableJpaRepositories annotation is not mandatory for auto configuring the spring-data-jpa but in some cases if spring component scan didn't recognize spring-data-jpa in classpath you will have to use this annotation to tell spring to autoconfigure it.
#EnableJpaRepositories will enabling auto configuration support for Spring Data JPA required to know the path of the JPA the repositories. By default, it will scan only the main application package and its sub packages for detecting the JPA repositories.So take care to put the main application class at the root package of your application.
#EnableJpaRepositories(basePackages ="com.ibm")
#SpringBootApplication(scanBasePackages = {"com.ibm"})
public class SBApplication {
public static void main(String[] args) {
SpringApplication.run(SBApplication.class, args);
}

Also, if your entity classes are not in the same package then you can use the #EntityScan annotation to specify the base packages. In your case you have not specifies the #Repository annotation on your interface which will tell spring-boot to create default implementations for your interface.If that annotation is not provided then spring will just ignore the interface and the bean creation will not happen.You won't be able to autowire it .So provide that and have methods declared in your interface and spring-bot will take care of the rest.
#Repository
public interface StudenteRepository extends CrudRepository<Studente, Integer>{
//If to find a student record by the id attribute
public Studente findById();
}

Is there any way to test an anonymous inner class using junit?

I have the following class that I would like to test. Having to test an anonymous inner class is proving to be very difficult. Any help would be appreciated.
#Configuration
public class CustomErrorConfiguration {
#Bean
public ErrorAttributes errorAttributes() {
return new DefaultErrorAttributes() {
#Override
public Map<String, Object> getErrorAttributes(RequestAttributes requestAttributes,
boolean includeStackTrace) {
Map<String, Object> errorAttributes = super.getErrorAttributes(requestAttributes, includeStackTrace);
errorAttributes.remove("timestamp");
errorAttributes.remove("status");
errorAttributes.remove("exception");
errorAttributes.remove("path");
if (errorAttributes.containsKey("error") && errorAttributes.containsKey("message")) {
Map<String, Object> attr = new HashMap<>();
attr.put("message", errorAttributes.get("message"));
return attr;
}
return errorAttributes;
}
};
}
}
This should be the minimum needed to test your inner class:
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;
#RunWith(SpringRunner.class)
#ContextConfiguration
public class BeanTest {
#Autowired
ErrorAttributes errorAttributes;
#Test
public void testMyBean() {
RequestAttributes requestAttributes = new RequestAttributes();
System.out.println(errorAttributes.getErrorAttributes(requestAttributes, true));
}
#Configuration
#ComponentScan(basePackages = "package.where.your.configuration.is")
public static class SpringTestConfig {
}
}
This test does a few things:
It leverages SpringRunner.class to create an ApplicationContext for you test.
The #ContextConfiguration annotation picks up the the static nested class SpringTestConfig. This class does the heavy lifting and actually scans base packages looking for other classes marked with Configuration, Bean, Component, etc. This will discover your Configuration which will in turn cause instantiation of your Bean.
Since the application context is now setup we can inject the bean with #Autowired as you would in normal application code.
I needed the following maven dependencies to accomplish this (junit >= 4.12 required). All are available in maven central:
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>5.0.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>5.0.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>5.0.0.RELEASE</version>
<scope>test</scope>
</dependency>

error: Type mismatch: cannot convert from Test to Annotation

I am newbie to junit Mockito framework, I have mocked the Dependency Injection using powermock framework, but I am getting error in eclipse on #Test annotation the error is "Type mismatch: cannot convert from Test to Annotation"
package org.singh.util.MockitoDemo;
import static org.mockito.Matchers.anyString;
import static org.powermock.api.mockito.PowerMockito.doNothing;
import static org.powermock.api.mockito.PowerMockito.mockStatic;
import static org.powermock.api.mockito.PowerMockito.when;
import static org.powermock.api.support.membermodification.MemberMatcher.method;
import org.junit.*;
import org.junit.runner.RunWith;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
#RunWith(PowerMockRunner.class)
#PrepareForTest({ExampleUtil.class, ExamplePojo.class})
public class ExamplePojoTest{
#Test
public void testMethodMakingPrivateMethodCall() throws Exception {
ExamplePojo spyExamplePojo = PowerMockito.spy(new ExamplePojo());
when(spyExamplePojo, method(ExamplePojo.class, "privateMethod", String.class)).withArguments(anyString()).thenReturn("test test");
String result = spyExamplePojo.methodMakingPrivateMethodCall("test");
Assert.assertEquals("test test", result);
}
}
maven dependencies are
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-mockito</artifactId>
<version>1.6.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit4</artifactId>
<version>1.6.1</version>
<scope>test</scope>
</dependency>
</dependencies>
When you see this error , it means you have a class name as “Test” in the same package.
Just rename that class name and it will work fine!!!!
