In this session, we introduce the Java developer to the Arquillian framework, Gradle and the Enterprise container technologies in Java EE 7. As a lucrative bonus we will cover building EJB and Java EE 7 tests applications with Gradle, the latest and greatest build framework for the Java platform, which improves on Apache Maven. The Java EE specification full contains three different containers, namely the Web, the EJB and the CDI containers. All of them can be reached using the Arquillian Framework, and this means there is now one general testing framework, which developers should learn as part of their professional duties. The session will cover writing meaningful tests for CDI, EJB and JAX-RS. Along the way, we will introduce new features of EJB 3.2, CDI 1.1 and RESTful Services. GlassFish Embedded Container 4.0 will be demonstrated.

5. Agile Software Development?

6. Why do we test?

7. Architectural Competencies
Performance and Efficiency
Stability and Robustness
Maintainability and Refactor-ability

8. Tools of the Trade
§ Frameworks: JUnit, TestNG and XUnit; JBehave, Spock, ScalaTest
§ Integrated Development Environment and Selenium

9. How do we test?

10. The Test Driven Cycle
Write A
Failing Test
Ensure All Make The
Tests Pass
Test Pass
Refactor the Refactor the
Main Code
Test
"Oh, East is East, and West is West, and never the twain shall meet.”, Rudyard Kipling, 1892

11. Essentials of Block Testing
Assign
Act
Assert

12. Traditional Java Enterprise Testing
Outside of the Container
Mock and Stub objects
Writing Tests around Deployment

15. Time to Change JavaEE Testing

16. Open Source Integration Testing
Peter Muir, David Blewin and Aslak Knutsen and from Red Hat JBoss.

17. Arquillian Test Framework
Portable In-Container Integration Testing
Deployment of Unit Test and Dependencies together
Extension of Existing Test Framework Support

18. Shrink Wrap
An Aid to Better Test Enterprise Components
“What if we could declare, in Java, an object to
represent that archive?”
Builder pattern for Virtual JAR file

19. Context & Dependency Injection 1.1
Inject Beans in strongly typed manner
Contextual Scopes, Qualifiers and Providers
Life-cycle, Event Management and Event Listeners

20. Gradle Dependencies I
dependencies {
compile 'org.jboss.spec.javax.annotation:jboss-annotations-api_1.2_spec:
1.0.0.Alpha1'
compile 'org.jboss.spec.javax.ejb:jboss-ejb-api_3.2_spec:1.0.0.Alpha2'
compile 'javax.enterprise:cdi-api:1.1-PFD’
compile 'javax.validation:validation-api:1.1.0.CR3'
compile 'org.hibernate:hibernate-validator:5.0.0.CR4'
compile 'org.hibernate.javax.persistence:hibernate-jpa-2.1-api:1.0.0.Draft-14'
runtime 'org.glassfish.main.extras:glassfish-embedded-all:4.0-b81’
testCompile 'org.jboss.arquillian.junit:arquillian-junit-container:1.0.3.Final'
testCompile 'org.jboss.arquillian.container:arquillian-glassfish-
embedded-3.1:1.0.0.Final-SNAPSHOT'
testCompile 'junit:junit:4.11'
}

21. Gradle Dependencies II
dependencies {
//...
compile 'javax:javaee-api:7.0-b81'
runtime 'javax:javaee-api:7.0-b81'
//...
testCompile 'junit:junit:4.11'
}

22. Arquillian Test Structure I
@RunWith(Arquillian.class)
public class BasicUserDetailRepositoryTest {
@Deployment
public static JavaArchive createDeployment() {
JavaArchive jar = ShrinkWrap.create(JavaArchive.class)
.addClasses(BasicUserDetailRepository.class,
UserDetailRepository.class, User.class)
.addAsManifestResource(
EmptyAsset.INSTANCE, "beans.xml");
return jar;
}
/* ... */
}

23. Arquillian Test Structure II
@RunWith(Arquillian.class)
public class BasicUserDetailRepositoryTest { /* ... */
@Inject
private UserDetailRepository userDetailRepo;
@Test
public void shouldCreateUserInRepo() {
User user = new User("frostj", "Jack", "Frost");
assertFalse( userDetailRepo.containsUser(user ));
userDetailRepo.createUser(user);
assertTrue( userDetailRepo.containsUser(user ));
}
}

24. Demo: Arquillian

25. Enterprise Java Beans 3.2
Session Beans as Java Co-Located or Remote
Service Endpoints
Transaction Support

Containment
Endpoints Extended to Web Services, JAX-RS and/
or WebSockets

26. Demo: Arquillian

WebSocket connections are peer full-duplex
HTTP interactions over a session
Reduced payload and lower latency
Designed for asynchronous operations,
performance and Efficiency

29. Embeddable Containers
So-called “Container-less” Web Application
Deliver an Container Embedded in Application
You Have Control: Size, Framework and
Libraries

30. GlassFish Embedded Initialization
public class AbstractEmbeddedRunner {
private int port;
private GlassFish glassfish;
public AbstractEmbeddedRunner init() throws Exception{
BootstrapProperties bootstrapProperties = new BootstrapProperties();
GlassFishRuntime glassfishRuntime =
GlassFishRuntime.bootstrap(bootstrapProperties);
GlassFishProperties glassfishProperties = new GlassFishProperties();
glassfishProperties.setPort("http-listener", port);
// glassfishProperties.setPort("https-listener", port+1);
glassfish = glassfishRuntime.newGlassFish(glassfishProperties);
return this; } /* ... */
}

31. GlassFish Embedded Start and Stop
public class AbstractEmbeddedRunner {
/* ... */
public AbstractEmbeddedRunner start() throws Exception{
glassfish.start();
return this;
}
public AbstractEmbeddedRunner stop() throws Exception{
glassfish.stop();
return this;
} /* ... */
}

32. GlassFish Embedded Deploy WAR
public class AbstractEmbeddedRunner {
/* ... */
public AbstractEmbeddedRunner deploy( String args[]) throws Exception{
Deployer deployer = glassfish.getDeployer();
for (String s: args) {
String application = deployer.deploy(new File(s));
System.out.printf("deploying "+application);
}
return this;
}
/* ... */
