Real Java EE Testing with Arquillian and ShrinkWrapDan Allen
Dan Allen presents on Arquillian and ShrinkWrap, tools for integration testing Java EE applications. Arquillian manages the lifecycle of containers to make integration testing easier. ShrinkWrap provides a simple API for programmatically assembling archives like JARs and WARs. Together they allow tests to run inside containers with the application code, avoiding lengthy builds. The talk demonstrates how to write tests using Arquillian and ShrinkWrap that inject resources and run application code directly in the same JVM for fast, isolated testing of Java EE components.
The document discusses challenges with testing Java EE applications and introduces Arquillian as a framework that aims to make testing easier. It provides flexibility through pluggable components, allows testing directly from IDEs, and abstracts server lifecycles. Key features include bundling test dependencies without repackaging, injecting resources into tests, and supporting various containers and test frameworks.
This document introduces Arquillian, a testing platform that allows tests to run against deployed applications. It enables testing Java EE components with real instances rather than mocks. Arquillian uses the Java EE container to deploy and manage test dependencies, eliminating the need for manual transaction management or persistence context handling. Tests are written like normal unit tests and interact with real objects instead of mocks. Arquillian makes testing components close to their production environment.
Arquillian: Effective tests from the client to the serverLukáš Fryč
Tools like Selenium, an outstanding tool for UI test automation, and Arquillian, an award-winning integration testing framework, offer a base for high-quality tests which are crucial for a web app development. However writing UI tests and covering server-side logic leaves many questions open:
* Does Selenium cover everything? Page transitions, simple JavaScript interaction and a portion of DOM. Is it really enough?
* Mocking requests for testing server-side code is pain. Is it necessary?
* Are you able to detect that your component’s visual representation changes?
* Does investigating these changes involve a disproportionate amount of effort?
* Isn’t manual test development too expensive?
Testing JSF with Arquillian and SeleniumLukáš Fryč
Testing of web applications is significant part of development cycle from perspective of both, application development and quality assurance.
JSF concepts makes testing of applications simple by separation of concerns, but enforces employing of specific tools for testing business logic and user interface.
Lukas covers testing pitas and introduce frameworks which make testing of JSF application a breeze and motivate developers to follow concepts of test-driven development.
Arquillian: Helping web developers and QA get alongLukáš Fryč
Modern development practices include testing our Web applications as a fundamental part of the application development lifecycle. Web UIs though can be particularly difficult to test with basic tools. Arquillian is an award-winning integration testing framework and Selenium WebDriver is an outstanding tool for UI test automation. Together they offer a base for high-quality tests.
This session looks to the Arquillian Universe for help. Equipped with the Arquillian extensions - Drone, Graphene and Warp - we will show you tests that cover both client-side (REST) and server-rendered (JSF) web applications. With a single test it is now possible to assert state (both in the server and on the client) at arbitrary points within the request lifecycle!
We will look at current best practices for how to achieve a rapid turnaround when doing test development by minimizing the effort required to write tests, and thereby increase productivity and thus making these tests future-proof. Additionally we will show tools and techniques that provide a separation of concerns between test authors (developers) and test automators (QA). How to execute a single test in both arbitrary server containers as well as arbitrary client browsers. And how it can enable us to run test suites in constrained environments like cloud-based continuous integration providers.
Test it! Unit, mocking and in-container Meet Arquillian!Ivan Ivanov
A gentle introduction into testing in Java. Begin with testing a single unit, continue with mocking dependency and end up with a full incontainer test capabilities.
Arquillian is an innovative and highly extensible testing platform for the JVM that enables developers to easily create automated integration, functional and acceptance tests for Java middleware, from Java EE and beyond.
For years we’ve been exploring how to layer and separate our code to test in isolation on the unit level. We’ve kept integration and functional testing as a big ball of mud; jumping straight from unit to full system testing. But can we apply some of the same lessons learned from unit to integration testing?
Speaker Bio:
Arquillian project lead, Aslak Knutsen, is a Senior Software Engineer at Red Hat where he is working on projects such as Arquillian and ShrinkWrap, one of the founders of the JBoss Testing initiative and a speaker at major industry conferences including JavaOne, Devoxx, Jazoon, JFokus, Geecon, JUDCon and JBoss World.
A presentation that guides you through the stages of testing your Java enterprise application. Finally it shows you that Arquillian is the best tool for that
This document summarizes different types of tests for Spring Boot applications, including unit tests, integration tests, and sliced tests. It discusses tools for mocking dependencies like MockRestServiceServer, Testcontainers for integration with Docker, and annotations like @MockBean and @SpyBean. Context caching, properties, and dirty context handling are also covered. The document concludes with an upcoming talk on JUnit 5.
The Spring Framework has always embraced testing as a first class citizen. Spring-based components should be modular, easy to wire together via dependency injection, and therefore easy to test. In fact, when well designed following a POJO programming model, a component in a Spring application can be unit tested without using Spring at all. And when you take the step toward developing integration tests, Spring's testing support is there to make your job easy.
Join Spring Test component lead Sam Brannen in this talk to learn about the basics for Spring's unit and integration testing support. This talk will provide attendees an overview of the following topics: unit testing without Spring, integration testing with Spring, loading application contexts (with and without context hierarchies), injecting dependencies into tests, transaction management for tests, SQL script execution, testing Spring MVC and REST web applications, and more.
With the proliferation of testing culture, many developers are facing new challenges. As projects are getting started, the focus may be on developing enough tests to maintain confidence that the code is correct. However, as developers write more and more tests, performance and repeatability become growing concerns for test suites. In our study of large open source software, we found that running tests took on average 41% of the total time needed to build each project – over 90% in those that took the longest to build. Unfortunately, typical techniques for accelerating test suites from literature (like running only a subset of tests, or running them in parallel) can’t be applied in practice safely, since tests may depend on each other. These dependencies are very hard to find and detect, posing a serious challenge to test and build acceleration. In this talk, I will present my recent research in automatically detecting and isolating these dependencies, enabling for significant, safe and sound build acceleration of up to 16x.
Hadoop Summit 2013 : Continuous Integration on top of hadoopWisely chen
Wisely Chen and Neal Lee presented on continuous integration on Hadoop. They discussed automating the software development process, including automatically running unit tests on code commits, performing tests on staging environments that mimic production, and deploying to production. They demonstrated tools for unit testing Hadoop jobs, including PigUnit and Vaidya for performance diagnosis, and how these tools can integrate with a continuous integration system to automatically run tests with each code change.
Have you ever wondered what the best way would be to test emails? Or how you would go about testing a messaging queue?
Making sure your components are correctly interacting with each other is both a tester and developer’s concern. Join us to get a better understanding of what you should test and how, both manually and automated.
This session is the first ever in which we will have two units working together to give you a nuanced insight on all aspects of integration testing. We’ll start off exploring the world of integration testing, defining the terminology, and creating a general understanding of what phases and kinds of testing exist. Later on we’ll delve into integration test automation, ranging from database integration testing to selenium UI testing and even as far as LDAP integration testing.
We have a wide variety of demos prepared where we will show you how easy it is to test various components of your infrastructure. Some examples:
- Database testing (JPA)
- Arquillian, exploring container testing, EJB testing and more
- Email testing
- SOAP testing using SoapUI
- LDAP testing
- JMS testing
Arquillian is a Java testing framework that allows running integration tests inside a container. It manages the container lifecycle and allows deploying test archives and accessing managed resources from tests. Citrus is a complementary framework for testing messaging interfaces like REST, SOAP, and JMS. It provides components to simulate clients and servers for messaging protocols. Together, Arquillian and Citrus allow testing applications by deploying them in a container and interacting with services through simulated messaging.
Docker в последняя время набрал огромную популярность как инструмент разработчиков и DevOps-специалистов, но все ещё не так активно используется для автоматизированного тестирования. Во время воркшопа я поделюсь несколькими сценариями, когда Docker может помочь автоматизировать то что ранее считалось непригодным к автоматизации. Также, мы попробуем создать свой собственный образ и запустить несколько контейнеров используя docker-compose.
This document provides an overview of integration testing. It discusses what integration testing is, the challenges of integration testing, and some solutions and best practices for integration testing. Specifically, it covers:
- The differences between unit testing and integration testing
- Examples of testing components together (like testing each part of a car separately vs doing a test drive)
- Techniques for reducing brittle and slow integration tests, like separating tests from infrastructure dependencies
- Tools for faking dependencies like databases, web services, and containers in integration tests
- Best practices for integration testing with build tools like Maven and for continuous integration

Make It Cooler: Using Decentralized Version Controlindiver
A commonly used version control system in the ColdFusion community is Subversion -- a centralized system that relies on being connected to a central server. The next generation version control systems are “decentralized”, in that version control tasks do not rely on a central server.
Decentralized version control systems are more efficient and offer a more practical way of software development.
In this session, Indy takes you through the considerations in moving from Subversion to Git, a decentralized version control system. You also get to understand the pros and cons of each and hear of the practical experience of migrating projects to decentralized version control.
Version control is often used in conjunction with a testing framework and continuous integration. To complete the picture, Indy walks you through how to integrate Git with a testing framework, MXUnit, and a continuous integration server, Hudson.
[FullStack NYC 2019] Effective Unit Tests for JavaScriptHazem Saleh
The document discusses code coverage and mutation testing tools for JavaScript. It introduces karma-coverage as a code coverage plugin that can be used with Karma test runner. Traditional code coverage only measures executed code and does not guarantee tests will fail on logic changes. Mutation testing seeds code with faults to evaluate test strength by whether faults are killed by tests. The document demonstrates Stryker, a mutation testing tool for JavaScript that works with popular frameworks and provides test reports. It provides sample URLs and recommends using Stryker with Angular CLI 6.1+.
Kamon is an open-source tool for monitoring JVM applications like those using Akka. It provides metrics collection and distributed tracing capabilities. The document discusses how Kamon 1.0 can be used to monitor Akka applications by collecting automatic and custom metrics. It also describes how to set up Kamon with Prometheus and Grafana for metrics storage and visualization. The experience of instrumenting an application at EMnify with Kamon is presented as an example.
The document discusses acceptance testing frameworks, including what they are, why they are worthwhile, and what should go into one. It defines an acceptance testing framework as one that defines the format for expressing expectations, drives the application under test, executes the tests, and reports results. Frameworks help avoid issues like brittle tests and performance problems that commonly occur with tools like Selenium. Effective frameworks have components like a runner, integration, configuration, reporting, logging, and a domain-specific language. The real value is realized by integrating frameworks with continuous integration to provide timely test results. Several open source and commercial frameworks are described.
Riga Dev Day - Automated Android Continuous IntegrationNicolas Fränkel
This document discusses setting up continuous integration for Android projects. It describes issues with dependencies like Gradle and Robolectric not working properly due to proxy restrictions. It proposes solutions like using a local Maven repository, configuring Gradle properties, and creating a custom Robolectric test runner and dependency resolver. It also addresses problems updating the Android SDK due to needing proxy authentication and license agreements. An Expect script is created to automate providing the credentials and agreeing to licenses during the SDK update process.

As the leading full-stack application framework for Java SE and EE, the Spring Framework continues to deliver significant benefits to Java developers, increasing development productivity and runtime performance while improving test coverage and application quality.
In this talk, core Spring Framework committer Sam Brannen will provide attendees an overview of the new features in Spring 3.2 as well as a sneak peak at the roadmap for 4.0.
Spring Framework 3.2 builds on several themes delivered in 3.1 with a continued focus on asynchronous MVC processing with Servlet 3.0, support for using @Autowired and @Value as meta-annotations, support for custom @Bean definition annotations, and early support for JCache 0.5. Regarding the internals, CGLIB 3.0 and ASM 4.0 have been inlined, and the framework is now built with Gradle and hosted on GitHub. For those interested in testing their Spring-based web applications, Spring 3.2 offers new support for loading WebApplicationContexts in the TestContext framework, and the formerly standalone Spring MVC Test project is now included in the spring-test module, allowing for first-class testing of Spring MVC applications.
Con el uso de CDI, para la inyección de dependencias, y la consolidación de la plataforma Arquillian, ya no hay excusas en la plataforma Java EE para el desarrollo de pruebas.
Este documento resume tres tipos de aplicaciones JEE: aplicaciones web Java, objetos distribuidos EJBs y aplicaciones empresariales. Describe las características de las aplicaciones web Java como colecciones de recursos como JSPs y servlets ubicados en URIs específicos. También explica cómo los EJBs se empaquetan en archivos JAR para distribución y cómo las aplicaciones empresariales combinan aplicaciones web y EJBs dentro de un archivo EAR.

Arquillian es un framework de pruebas que permite levantar un contexto CDI embebido y realizar pruebas unitarias y funcionales en proyectos Java. Se integra fácilmente con Maven y funciona con librerías de prueba como JUnit y TestNG. Arquillian despliega artefactos como JARs y WARs con las clases CDI disponibles usando ShrinkWrap, y ejecuta pruebas en contenedores de aplicaciones como JBoss y Glassfish.
Java Enterprise testing using Arquillian framework makes a tour under arquillian universe and show some of its extensions like persistence, Drone, Graphene, Cuskes in space(cucumber) and jacoco. The presention is guided by practical samples hosted on github.
This document discusses how to test enterprise Java applications. It recommends that unit tests cover 80% of code to test small pieces of code and give confidence to make changes. Integration tests cover 15% of code to test collaboration between components like databases and servers. Acceptance tests cover the remaining 5% by testing customer requirements through concrete examples and user stories. The document provides examples of testing frameworks for different layers, including JS TestDriver and Sinon.js for client-side tests, JUnit and Mockito for server-side tests, and DBUnit and Arquillian for persistence tests. It emphasizes the importance of continuous integration to run tests automatically and ensure quality.
The document discusses testing Java EE applications with Arquillian. It provides an overview of Arquillian and how to use it to test servlets, JSF, EJB, JPA, JAX-RS, web services and more. Arquillian allows testing Java EE components in an isolated and integrated way using embedded containers and coordinates the component lifecycles. It is a robust and modern solution for end-to-end Java EE testing supported by a vibrant community.
Making Your Results Visible - A Test Result Dashboard and Comparison ToolXiaoxing Hu
This document introduces REPAUTO, a test automation framework that aims to address common issues like flaky tests. It summarizes the key problems such as the large number of tests, devices and networks that can cause failures, and the difficulty of debugging issues. The framework proposes centralized logging, history comparison and flake detection to make triaging easier. It was built with technologies like Allure and MVC, and the source code is available on GitHub for feedback.
La máquina virtual y la plataforma Java se está convirtiendo en el pilar de multiples lenguajes: Java, Scala, Groovy, Clojure, Ceylon, JRuby... pero muchos desarrolladores no conocen como funciona por dentro tanto el sistema de memoria como el recolector de basura. Este conocimiento es fundamental y puede marcar la diferencia entre dos programadores.
Esta charla consisitirá en una introducción a la gestión de memoria de la JVM (Hotspot), cómo trabaja el recolector de basura o algunas opciones para poder configurar las opciones por defecto.
Si alguna vez te has cruzado con un OutOfMemoryError y no entendistes la línea que copiastes de StackOverflow: esta es tu charla.
Sauce Labs hosted a Selenium bootcamp webinar with guest speaker Dave Haeffner. This presentation will give you a basis for the detail given in Dave's like titled E-book and get you started with Selenium.
Testing Java EE Applications Using ArquillianReza Rahman
This session outlines how to effectively test Java EE APIs like JSF, Servlet, CDI, EJB 3, JPA, WebSocket and JAX-RS. Java EE includes a number of new features that enhance testability like generic dependency injection, CDI @Alternative, portable extensions, embedded containers and JSF project stages.
Using these features and best of breed tools like JUnit and Arquillian it is possible to perform unit, integration, system and functional testing for Java EE APIs at all layers of the application. In addition to discussing tools and features, the session will also demonstrate testing techniques like designing for testability, mock objects, isolation and test configuration.
Page Objects Done Right - selenium conference 2014Oren Rubin
The document discusses page object design patterns for test automation. It describes four main steps: 1) Expose the service or page being tested rather than using WebDriver APIs directly in tests. 2) Eliminate random sleeps by adding wait methods. 3) Support different users by overloading methods or using parameters. 4) Initialize page objects using a page factory to avoid duplicating lookup code. It also discusses using coordinators to synchronize tests by waiting for events from the application under test.
Reactive Java EE - Let Me Count the Ways!Reza Rahman
As our industry matures there are pockets of increased demand for high-throughput, low-latency systems heavily utilizing event-driven programming and asynchronous processing. This trend is gradually converging on the somewhat well established but so-far not well understood term "Reactive".
This session explores how vanilla Java SE and Java EE aligns with this movement via features and APIs like JMS, MDB, EJB @Asynchronous, JAX-RS/Servlet/WebSocket async, CDI events, Java EE concurrency utilities and so on. We will also see how these robust facilities can be made digestible even in the most complex cases for mere mortal developers through Java SE 8 Lambdas and Completable Futures.
The document describes a QA automation solution architecture. The solution uses a test management tool to organize and manage test cases. A BDD tool is used to write automated tests in readable text format and link them to code in a testing project. An automation framework acts as a wrapper for drivers, organizing project components and allowing tests to use commands. A CI tool takes the testing code and runs it on virtual machines, displaying test results via a browser. Reports provide information about test sessions, the overall testing session, and details of individual tests with logs and screenshots.
테스트 어디까지 해봤니? Arquillian을 이용한 Real Object 테스트jbugkorea
The document discusses Arquillian, a testing framework that allows integration tests to be written and run similarly to unit tests. It can package components into deployable archives, launch tests inside a container, and support running tests from an IDE. Benefits include being able to run integration tests incrementally like unit tests without needing to rebuild between test runs.
The document discusses Arquillian, a testing framework that allows integration tests to be written and run similarly to unit tests. It can package components and their dependencies into a deployable archive. Tests using Arquillian can be run inside an IDE, incrementally built, and debugged like unit tests. The framework provides a component model for tests that encapsulates business logic and allows flexible configuration of the test classpath and deployment.
The document discusses testing Docker images to ensure software quality on the cloud. It describes using tools like CTF, Behave, Arquillian Cube, and CE-ARQ to define test scenarios and run smoke tests on images built with Source-to-Image (S2I) to test functionality, parameterization, configuration, and builds. Tests are run locally or in a "TestRunner Pod" on OpenShift using templates, applications, and test classes defined in an Arquillian XML descriptor. References are provided to relevant GitHub repositories.

Level Up Your Integration Testing With TestcontainersVMware Tanzu
The document discusses Testcontainers, a Java library that makes it easy to create lightweight, disposable Docker containers to support integration testing. Testcontainers allows developers to start containers for databases, browsers, and other services via simple annotations and eliminates the need to manage complex Docker configurations and container lifecycles manually. It integrates with JUnit and handles starting a new container before each test and cleaning it up afterwards, improving testing fidelity by mimicking production environments.
2014 Joker - Integration Testing from the TrenchesNicolas Fränkel
This document discusses integration testing and provides guidance on how to effectively test systems with dependencies on external resources like databases and web services. It emphasizes separating integration tests from unit tests, faking dependencies using tools like in-memory databases and SOAPUI, and testing applications in their real container using the Spring Test framework.
Throwing complexity over the wall: Rapid development for enterprise Java (Jav...Dan Allen
For many, development of enterprise Java has long been an arduous undertaking. We're of the opinion that application programmers should be free to focus on their business logic only.
In this session, we'll cover:
• What makes us most productive?
• What tasks should we be programming; more importantly, what shouldn't we?
• What is a component model, and what does it buy us?
• How is this stuff usable in the real world?
We'll discuss how testing relates to the features of the Java EE 6 stack. By the end, we'll have introduced a pair of simple and powerful frameworks that render the testing of real enterprise components as natural as calling "add" on a CS101 Calculator.java.

Embracing Disruption: Adding a Bit of Chaos to Help You GrowPaul Balogh
** Recording available at https://www.youtube.com/watch?v=sHNOjUtbq2s **
Failure happens! It's our job to turn these disruptions into learning opportunities. As our software has become more distributed and complex, the "shift-left" movement brings reliability testing to earlier stages of development. Ensuring reliability goes beyond simple end-to-end tests.
To ensure the highest levels of reliability, you must perform a suite of testing types. Incorporate contract tests to validate APIs; load tests for scaling predictability. Let's learn from Chaos Engineering principles by incorporating disruptive behavior into your system _before_ production.
Join Paul as we learn ways to incorporate a plethora of testing into your software development pipeline. We'll discuss the pros and cons of each and what you can do to add these to your processes.
By embracing a little disruption, you can significantly improve the reliability of your system.

Introductory talk to PicketLink from Federation through to Identity Management.
What is PicketLink?
PicketLink is an umbrella project for security and identity management for Java Applications. PicketLink is an important project under the security offerings from JBoss.
A Picket Fence is a secure system of pickets joined together via some type of links. Basically, the Pickets by themselves do not offer any security. But when they are brought together by linking them, they provide the necessary security.
This project is that link for other security systems or systems to bring together or join, to finally provide the necessary secure system.

Compensating Transactions: When ACID is too muchJBUG London
The talk was presented by Dr Paul Robinson (Red Hat) at the London JBoss User Group event on the 25th of September 2013.
Video available soon
ACID transactions are a useful tool for application developers and can provide very strong guarantees, even in the presence of failures. However, ACID transactions are not always appropriate for every situation.
ACID transactions are achieved by holding locks on resources and require the ability to rollback changes. In some situations, the blocking nature of the protocol can be too limiting to performance, especially if the transaction is distributed. Also, some actions can’t simply be rolled back; for example, sending an email.
A common strategy for applications that can’t use ACID, is to throw out transactions altogether. However, with this approach you are missing out on many of the benefits that transactions can provide. There are alternative transaction models that relax some of the ACID properties, while still retaining many of the strong guarantees essential for building robust enterprise applications. These should be considered before deciding not to use transactions at all.
In this talk, I’ll present one such alternative to ACID transactions: compensation-based transactions. I’ll provide an overview of ACID and it’s limitations and describe some use-cases where ACID is not appropriate. I’ll then present our new API for compensation-based transactions and demonstrate how it can be used to address these problems. Finally, I’ll present our future plans to improve and expand our support for compensation-based transactions.

The document describes how Infinispan was used to improve the performance and scalability of two different systems - an existing production system (Part 1) and a new greenfield project (Part 2).
For the existing system, Infinispan replaced EhCache to distribute caching across multiple nodes and reduce heap usage. Benchmarking was used to validate the solution. Issues encountered with Hotrod were addressed by using embedded caching instead.
For the new project, distributed caching did not work due to high network traffic. Distributed execution was used instead, where tasks are run on nodes containing the data to minimize traffic. This reduced latency from 2 seconds to 200ms.
Hibernate OGM - JPA for Infinispan and NoSQLJBUG London
Hibernate OGM provides JPA support for NoSQL databases like Infinispan. It allows using the familiar JPA programming model while storing data in a flexible NoSQL database. Hibernate OGM acts as a JPA front-end that handles CRUD operations and basic queries, persisting objects to Infinispan. The goal is to encourage new data usage patterns with volume and types while using a familiar Java environment.
