Category: Testing

Automate JavaScript tests in an integration environment using Arquillian

 

Status: Proposed

 

Summary of idea:

 

The goal of this project is to make automation of JavaScript tests in an integration environment as simple as Java tests by tying execution into the Arquillian ecosystem. We also want to be able to achieve rapid development of the JavaScript tests in the IDE. Running the test suite in continous integration (CI) is equally as important as quick development turnaround.

 

We want to leverage existing test frameworks where possible. One possible approach is to create an Arquillian test runner for QUnit tests and use Arquillian Drone to handle controlling the browser. This stack integrates Selenium and QUnit tests so that QA does not need to configure the browser pool twice for Selenium and QUnit tests. To support quick turnaround in development, we can use another framework, JsTestDriver, to grab an existing browser session and reuse it. This avoids having to spawn a browser repeatedly.

 

When this project is complete, developer should be able to agree that running JavaScript tests in both the IDE and a continous integration environment is as simple as running Java tests.

 

Knowledge prerequisite: Java, JavaScript, JavaScript testing, IDE (Eclipse or IntelliJ)

Extend Arquillian to support Spring testing (beans and MVC controllers)

 

Status: Proposed

 

Summary of idea:

 

Arquillian provides an extensible testing platform that can be used for testing any type of Java-based component. The initial focus for Arquillian was testing Java EE components, such as CDI beans, EJBs and JPA. However, Arquillian provides all the infrastructure and hooks necessary to make it an ideal testing platform for Spring applications.

 

It's already possible to test Spring beans using Arquillian by packaging the Seam 3 Spring library in the test archive and injecting Spring beans into the test by way of CDI. However, the use of CDI here is unnecessary, since Arquillian already provides an extension point for creating a custom "test enricher", specifically a dependency injection bridge. In the first phase of this project, the student will create an Arquillian extension that provides a test enricher that loads Spring and looks up Spring beans for Arquillian to inject into the test case. This functionality effectively emulates the Spring TestContext framework (with proper isolation of the test archive of course).

 

In the next phase of the project (if there is time), the student will extend Arquillian to enable testing of Spring MVC controllers. This functionality is very similar to the Arquillian JSFUnit extension that enables testing of JSF inside the container. There is already some work that has been done for testing Spring MVC controllers using a Spring-centric approach in the Spring MVC Test project. This project can serve as a good model for what we want to achieve using Arquillian as the test platform.

Discussion: GSoC - Arquillian Spring Integration

 

Decouple GWT testing from Jetty and allow integration testing in any container

 

Status: Proposed

 

Summary of idea:

 

Currently GWT integration tests using GWTTestCase are coupled with Jetty. This limits guarantees of GWT integration tests, and increases the complexity of project setup, when Jetty is not the target deployment environment. The goal of this project is to decouple this test framework from Jetty and hook it up to the Arquillian test platform. By integration with Arquillian, it's possible to leverage the Arquillian container adapters to allow integration testing on any supported container (including Jetty).

 

In the next phase of the project, the student will tackle using ShrinkWrap micro-deployments for integration testing GWT. The lack of support for fine-grained, quick turnaround integration testing is a major missing piece of GWT. The GWT compiler could be forced to compile only portion of UI logic which could be tested in separation. This decreases time needed to compile deployment and allows testing units in separation.

 

When this project is complete, GWT tests will be much more flexible and efficient. It will be possible to run GWT tests on any container supported by Arquillian, tests will be more fine-grained, resulting in faster turnaround and developers will be able to experiment with other available Arquillian extensions for GWT testing.

Integrate Sahi into Arquillian Drone for automated browser testing

 

Status: Proposed

 

Summary of idea:

 

Arquillian Drone is an abstract layer over browser controllers such as Selenium, WebDriver and HtmlUnit that integrates with the Arquillian testing platform to automate browser testing. Drone provides extension points to allow any browser controller with a Java API to be supported. Some developers prefer Sahi over Selenium for testing rich web applications such as those written using GWT. The goal of this project is to add support for Sahi in Arquillian Drone.

Integrate Robotium into Arquillian Drone and Android extensions for complete automated application testing on Android

 

Status: Proposed

 

Summary of idea:

 

The goal of this project is to add support for native Android application testing in Arquillian, leveraging Arquillian Drone as the controller. This focus of the project is on bringing together several well-established testing frameworks into a single, powerful stack.

 

The Arquillian Android extension is an integration layer between Android SDK and Arquillian. It allows you to start and stop Android emulators, connect real devices and install arbitrary packages. It's basically a way to control the Android Debug Bridge from Java environment. Currently, the Android extension supports testing web-based applications via integration with Arquillian Drone and the Selenium AndroidWebDriver.

 

Robotium is a framework based on top of Android SDK activity and  testing, which allows you to do a blackbox testing of the native application running on an Android device. An activity represents a part of the application (e.g., a screen) the user can interact with in order to do something. Robotium resembles Selenium in many aspects, except it works on native screens instead of web pages.

 

Arquillian Drone is an abstraction layer over browser controllers such as Selenium, WebDriver and HtmlUnit that integrates with the Arquillian testing platform to automate browser testing. Drone provides extension points to allow any browser controller with a Java API to be supported. Since Robotium allows you "to browse" Android applications, it can be used as a browser from Arquillian Drone.

 

This project can devided into two distinct phases. The first one focuses on decoupling InstrumentationTestRunner from Android SDK and integrating into Arquillian. This will allow running any Android integration tests directly in Arquillian. The second phase is about adding Robotium into Arquillian Drone as a supported browser.

 

By integrating Robotium, developers will be able to focus on writing test logic and let Arquillian handle the integration work and automation. The developer will profit from much simpler configuration and possibly from integration with other Arquillian extensions.

Add support for scriptable data sets in DBUnit, building on the Arquillian Persistence Extension

 

Status: Proposed

 

Summary of idea:

 

The key strength of Arquillian as testing platform is its extensibility. Arquillian Persistence Extension is one of many add-ons. The main rationale behind it is to remove boilerplate code needed to prepare the database and make you a happy and productive programmer!

 

This extension uses DBUnit to populate test data. DBUnit is a popular and mature tool aiming to help developers with data driven tests. It provides an abstraction to manipulate test data called DataSet (in the form of XML, Excel file or formats added by the Arquillian Persistence Extension, such as YAML and JSON). The DataSet represents a collection of tables (rows) used to seed the database. However it's static nature is not sufficient in many cases. Imagine testing time sensitive data. It could be really handy to have possibility of defining date as "three days from today" or having current time by simply invoking "now()" function. With the power of a scripting language at your disposal it should be achieved very easy.

 

The goal of this project is to extend the Arquillian Persistence Extension usage of DBUnit and introduce the concept ScriptableDataSet. By leveraging "Scripting for the Java Platform" (JSR 223) introduced in JDK 6 we can use plethora of languages to add dynamic flavor to our data driven tests.

 

Knowledge prerequisite: Java, some basic knowledge of scripting languages (JSR-233, could be Groovy, Python, JavaScript, Ruby), DBUnit, JUnit, TestNG

Define an object-oriented API for defining test data for the Arquillian Persistence Extension

 

Status: Proposed

 

Summary of idea:

 

DBUnit data sets are low-level, database oriented test fixtures. Hence it's often quite cumbersome to write them by hand, especially when there are relationships between entities/tables. The goal of this project is to introduce an alternative way of describing test data in external, human-readable text files representing object structure (entities), not rows as it's in DBUnit case. Considered formats are YAML or JSON.

Java, some familiarity with testing techniques and frameworks such as JUnit or TestNG.

Integrate test data generation into Arquillian

 

Status: Proposed

 

Summary of idea:

 

Combinator libraries such as Haskell's QuickCheck are designed to generate boundary test cases based on some assertions about logical properties that given behaviour should fulfill. The goal of this project is to provide such functionality for Arquillian-powered tests. Already existing solutions such as ScalaCheck, JCheck or Quickcheck could be leveraged to achieve it.

Unleash the Jester on integration tests by adding support for mutation testing in Arquillian

 

Status: Proposed

 

Summary of idea:

 

Mutation testing is a software testing method which is based on the idea of modifying source or bytecode in order to capture weakneses of your test suite. In other words using this technique you can test your tests! By applying different mutations, such as changing operators, variable names or throwing exceptions, to your test code you have a chance to locate issues in your code.

 

The goal of this project is to research the possibilities of integrating Arquillian with mutation testing tools such as PIT. Another angle would be to investigate how we can leverage Byteman in this context (some work has already been done to integrate Byteman into Arquillian).

Automated Client-Side Profiling

 

Status: Proposed

 

Summary of idea:

 

An optimization of the client-side performance for web applications is based on optimizing the application

source code in order to allow fluent loading of resources and fluent rendering.

 

To provide optimized loading, it's necessary to keep set of best practices each developer should have in mind when coding application [1].

There are several tools which can detect violation of some of these rules [2].

 

The detail of a page loading process can be then displayed as graph. There are several browser tools

which are able to collect and display these informations [3].

 

Periodical checking of these informations may be time-consuming, especially for big applications with many application views. But the process can be automated using browser automation tools like Selenium [4].

 

At first, basic informations about page needs to be collected - the violation of performance rules, number of HTTP requests for page load, the time needed for displaying the page, the time before executing first script. These informations needs to be compared to historical data and significantly worse results needs to be considered as failure.

 

At second, the whole detailed profile of page loading can be retrieved from browser, to be able review the real data and compare them with historical progress.

 

There are two projects which enables similar functionality: commercial DynaTrace [5] and open-source BrowserMob Proxy [6] together with HAR Viewer [7].

 

The goals of this project are:

1. deepen the knowledge about the page loading with data provided directly by browser

2. write simply-to-setup automation using Selenium

3. automated analysis of data and system of failure detection

4. integrate with Arquillian framework (Arquillian Drone)

Automated Visual Verification

 

Status: Proposed

 

Summary of idea:

 

The visual verification of web applications is time-consuming and error-prone process.

The idea of this project is avoiding as big part of the process with employing automated verification tools.

 

The goal of the project is writing client, which would allow QA engineers to hook into functional tests and automatically collect screenshots of the tested pages after each simulated user interaction.

 

The tool automatically generates sequence of screenshots for each test case. First run of the tool generates sample set of images, which needs to be reviewed manually. In any further run of the tool, sample set of images is compared with new screenshots. Any deviation is reported as needs to be reviewed manually.

 

The first part of implementation builts on top of Arquillian Drone and Arquillian Graphene extensions and allows automatic screenshot collection.

 

Second part of implementation is a desktop tool for loading and analyzing of the results of comparison with the easy-to-review listing of results.

Server-Side Performance Testing Framework reusing Arquillian Core

 

Status: Proposed

 

Summary of idea:


The testing of the performance of the Java enterprise application isn't as simple as it could be.

In ideal state, user defines only how "request" to application looks and the rest can be managed by

testing framework.

 

The idea behind this project is to allow API for performing client testing (where mock request is emited outside of container) as well as in-container testing (allow to interact with internal server APIs accessible from deployed application).

 

The goal of this work is to design tool for distributed performance testing, which would allow use following components: application server, load balancer, load generators (clients), measurement tools (CPU, Memory, bandwidth), performance data collectors.

 

The collected results will be plotted to graphs to enable simple reviewing process in continuous integration systems.

 

The proposal of the work is to use decoupled eventing system similar to CDI or Arquillian Core, which would allow to plug into the process and enhance/overwrite implementation where necessary. Obviously, the eventing system needs to be designed with high-throughput in the mind.

 

The target platform is Arquillian framework. As reference implementation of application server, JBoss Application Server 7 should be used.

Implement a Plugin to add "Undo" functionality to Forge

 

Status: Proposed

 

Summary of idea: Implement a Forge plugin to decorate execution of all commands to allow undo functionality (a Git time-machine).

 

Since Forge makes changes directly to the project, users might get nervous about using the commands or accidently put the project in a state they want to revert. We want to provide an exit scenario. Upon completion of a command, the changes should be saved as a new revision in a git history branch. Of course, this will require stashing unstaged changes to avoid messing up the git workspace. From the branch, the user can test that the project was changed in the way they expect. If everything looks good, Forge will help the user merge the changes back into the their main working branch, reapplying any stashes as necessary. If things don't look good, the user can ask Forge to nuke the temporary branch, effectively rolling back all changes to the state before the command was executed. (See more details here: https://issues.jboss.org/browse/FORGE-320 ) This should behave a bit like a Git time-machine.

Implement a Forge plugin to create RHQ plugins

 

Status: Proposed

 

Summary of idea: Implement a Forge plugin that helps generating RHQ plugins. This could be in a sort of standalone way (much like the existing rhq plugin generator) or better in a form that you can instrument your app, generated by Forge with code points that expose application metrics, that can then be picked up by the RHQ plugin.

BPMN2 based Web App for replaying and stepping through activity information captured from a business transaction executing within a SOA

 

Status: Draft

 

Summary of idea:

 

As part of the SOA governance initiative within jboss.org, we are developing service activity monitoring capabilities to capture the activities associated with business transactions as they execute across services within a SOA.

 

This information will include details regarding interactions between services, as well as details related to the internal tasks executed to achieve the business goal.

 

The BPMN2 Web App will use a Choreography model (describing the end-to-end business process) to represent the communications that occur between services, and a Process model per service to either (a) elaborate the internal logic implemented by each service, where that services is using a BPMN2 execution engine, or (b) the abstract externally observable behavior where the service is implemented using a different technology.

 

The user will be able to retrieve activity information regarding the execution of a particular business transaction instance, and observe how it executed across services (at the Choreography level), as well as being able to drill into the individual services (using the Process model representation) to examine further levels of detail.

Summary of idea:

 

Drools Guvnor has grown immensely in function and form leaving the asset editors in Drools Eclipse plugin behind. In order to

minimise the effort to develop and support two divergent code-bases offering the same authoring tools this project would look to

provide re-use of GWT based widgets in Eclipse. Furthermore the dependency Guvnor has on a JCR repository is to be removed,

allowing assets edited within Eclipse to be stored as files under the control of Eclipse and any Version Control System the

Eclipse user may have configured.

Provide a generic framework to record and allow playback of operations performed on assets within Drools Guvnor to

facilitate the provisioning of undo-redo features. Furthermore, once complete, the concept of a list of changes (or undo

log) made to assets will allow the identification of whether an asset has changed and hence prompt user before closing

such with unsaved amendments.

Drools Verifier produces a XML report about the defects found from

Drools rule language code and about the relationships between the

rules and facts used in the code. The goal is to create a read only

report that visualizes this data. The end result will be similar to

what you would get when you merge JavaDocs and a FindBugs report.

Dynamic visual BPMN2 Diff tool for jBPM Web Designer  

Status: Draft

 

Summary of idea:

 

Being able to track how your Business Processes change over time is an important feature of BPM efforts.

Text-based diff tools already exist but are not suitable/useful for comparing BPMN2 processes. Visual comparison

between process versions should prove as a much more suited way of being able to compare business process

changes over time.

The work in this proposal deals with creating a plugin tool in jBPM Web Designer open-source web application

to add ability to visually compare multiple BPMN2 process versions.

Smart Data Mapping and Associations  for jBPM Web Designer  

Status: Draft

 

Summary of idea:

 

jBPM Web Designer provides a web-based editing environment for creation of executable BPMN2 business processes.

A part of creating executable business processes is providing execution semantics to the visual model such as

defining process variables, data input/output sets, assignments and associations. This is currently a manual process

which is time consuming and error-prone as the business model changes over time.

The work in this proposal deals with developing a smart and intuitive/predicting way of working with data mapping and

associations within a BPMN2 business process, all within the jBPM Web Designer open-source web application.

Replace old graphs in RHQ with GWT ones

 

Status: Proposed

 

Summary of idea: Replacement of old graphing with a new GWT implementation. This can be done with the help of existing graphing libraries for GWT. The replacement does not need to be 1:1, but there is freedom to implement different representations. A nice extension would be to be able to define a formula that translates the graph on the fly or where multiple metrics could be combined via formula.

Implement a RHQ storage backend using Infinispan

 

Status: Proposed

 

Summary of idea: Implement a backend for data storage based on Infinispan (e.g. for metric data). Currently all (metric) data is stored in a relational database. With cheap memory, one could replace parts of this with alternative backend storage, that is memory based. Infinispan is a powerful data grid, which also provides the ability to run jobs on the local nodes, so that e.g. baseline computation can run on the Infinispan backend.

Implement a big screen dashboard for RHQ

 

Status: Proposed

 

Summary of idea: Implement a "big screen dashboard" on top of the REST api. The idea is to have a huge screen, that shows many metric graphs (like those you see in the NASA control room when satellites are launched). The user should be able to select the graphs to be shown and also the position on screen. The graphs should be able to display multiple metrics and availability (and perhaps other indiators) and thus allow to give a quick overview over the system state. There already exists a prototype with the help of jQuery and D3.js

Summary of idea: Create an HTML5/JS/PhoneGap based application from start to deployed in app stores (iTunes, Android, etc..) that allows for simultaneous document collaboration between any number of users. Users can edit an online document at the same time and see each others changes in real time using websockets. There should also be an area for user chat and possibly file sharing again using websockets for chat and native file system access, camera access, etc. for sending and receiving files. Also, local storage or device storage could be leveraged for offline document creation/initialization and once a connections is established, a collaborative document is created from the locally stored version.

 

This project is ambitious and will be challenging!  However it will also involve some of the most advanced and sought after technologies in the mobile industry.  Taking this application through the app store process is also incredibly valuable to understand, and paves the way for future efforts.  We'll be looking for 1-3 motivated applicants to make this a reality!

jBPM on Android

 

Status: Draft

 

Summary of idea:

The jBPM core engine itself is so lightweight that it could actually be run on android as well.  Based on an existing prototype, this could be extended so jBPM could actually be used to develop and execute simple applications on android.  This for example could include creating custom nodes for common android functions (like opening a web page, getting current location, etc.), configuring persistence to use the persistence mechanism offered by android, simple client interfaces for inspecting human task lists, managing process instances, etc.

The blog entry describing a first prototype can be found here.

Integrating jBPM with your own preferred project(s)

 

Status: Draft

 

Summary of idea:

jBPM allows you to integrate with external services by creating your own domain-specific nodes that are added to the process palette and can be used inside your business processes to model specific services.  While some of these services might be very specific to your problem domain, a lot of generic and reusable integrations could be implemented, like integration with Email, RSS feeds, Google Calendar, REST services, known web services to for example retrieve stock data, weather information, etc.  These could then be added to a repository or library of domain-specific nodes so that the process author could for example select which of those he wants to use as part of his process.

We would like to extend the set of integrations that we support out-of-the-box by adding new integrations with existing services and projects.  This is an ideal opportunity to integrate jBPM with the some of the projects you love!

Simple Certificate Management System

 

Status:Proposed

 

Summary of idea:

 

The Java Key Store has historically been used to manage certificates and keys.  This idea is to create a simple certificate management system for PicketLink that will have database/ldap storage and a nice interactive scripts for usage.

 

What I envision is Java code that will deal with the certificate mgmt system to CRUD certificates.  The scripts (*.sh and *.bat) should just call the Java code dealing with Cert MS.

 

Knowledge prerequisite: Java, X509 Certificates basics.

Atmosphere/WebSocket integration for JBoss AS 7

 

Status: Proposed

 

Summary of idea:

The WebSockets are upcoming standard for real-time asynchronous messaging, but since it haven't been standardized yet, it's hard to manage all the complexities in end-user applications.

 

Atmosphere project focuses on bridging the gap of standardization and supports not only WebSockets integration with various containers like Glassfish and Jetty, but it also offers graceful degradation to Comet mechanism when no support detected on the client or server, which allows you to bring the asynchronous client/server messaging to the current applications with broad support of clients.

 

The goal of this project is to extend Atmopshere's support for WebSockets in JBoss Application Server 7.

The JBoss AS7 is based on Tomcat implementation, which already contains experimental WebSocket support.

 

The project comprises of writing extensions for both, AS7 and Atmosphere and making sure that all the Atmosphere

samples works.

A Jenkins plugin to visualize Jacoco code coverage reports

Status: Not submitted yet


Summary of idea:

Jacoco is becoming the main Code Coverage tool on the JVM, mainly because of how easy it is to set up. However, Jacoco is still young and missing some integrations with some other pieces of a Continous Improvement plaftorm. The major missing integration is the lack of Jacoco plugin for Jenkins/Hudson. Such a plugin would allow to get metrics and see line-by-line reports about code coverage using a jacoco.exec file provided by the buld. The aim of this proposition is to develop this plugin, which will be first widely used in the JBoss Community and that will be shared with the whole Jenkins/Hudson community as it is the case for other coverage plugins.

Provide ShrinkWrap with Export to: RPM, ISO, RAR, BZIP Formats

 

Status: Proposed

 

Summary of idea:

Currently, ShrinkWrap (an Archive API for Java, functions as a virtual filesystem) supports export to ZIP, TAR, and TAR.GZ formats.  In order to expand ShrinkWrap's use outside of an EE context, it'd be beneficial to have export options for the RPM, ISO, and/or RAR format, as well as a filter to provide BZIP compression.

 

Knowledge prerequisite:

No external dependencies, so anyone decent at I/O, the java.io package, and willing to research the protocols above are good candidates.  Mentor will provide some assistance to those new with Git (version control), running the build and the tests, etc.

 

Skill level:

Beginner to Intermediate; a good place for students familiar with the Java Language and some common programming structures to start in open source.
