    Idea Proposals

     

    Below is a list of the ideas that have been proposed for the GSoC 2012 program. The ideas are organized by category.

     

    Category: Testing

    Automate JavaScript tests in an integration environment using Arquillian

     

    Status: Draft

     

    Summary of idea:

     

    The goal of this project is to make automation of JavaScript tests in an integration environment as simple as automating Java tests by tying into the Arquillian ecosystem. We also want to be able to achieve rapid development of those JavaScript tests in the IDE. Running the test suite in CI simply is important equally important to 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, IDE (Eclipse or IntelliJ), some familiarity with Arquillian

     

    Skill level: Medium to High

    Notes: More details can be found in the resources below:

     

     

    The focus of this idea is running JavaScript only tests using JavaScript unit testing frameworks, not invoking JavaScript from Selenium tests, which is a separate idea.

     

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

     

    Status: Draft

     

    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 adapter. 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.

     

    In the next phase of the project, 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.

     

    Knowledge prerequisite: Java, Spring, Spring TestContext, some familiarity with Arquillian

    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.

     

    Knowledge prerequisite: Java, GWT, some familiarity with Arquillian

    Integrate Sahi into Arquillian Drone for automated browser testing

     

    Status: Draft

     

    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. Many 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.

     

    Knowledge prerequisite: Java, Sahi or Selenium, some familiarity with Arquillian

    Hopefully we'll have some more Forge ideas here soon!!

     

    Implement a Plugin to add "Undo" functionality to Forge

     

    Status: Proposed

     

    Summary of idea: Implement a Forge plugin to decorate execution of all commands. If a command executed successfully, changes should be saved as a new revision in a git history branch. If commands the user should be prompted to ignore, or roll 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.

     

    Knowledge prerequisite: BPMN2, Java, GWT, SVG

    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.

    Design and implement a generic wizard on top of the REST api

     

    Status: Proposed

     

    Summary of idea: Design and implement a generic wizard on top of the REST api to create e.g. alert definitions or to start operations. This is part of a bigger picture to use RHQ as a data hub, where several clients can deliver and request data from. This means to have a web page that uses the HATEOAS principles to guide the user through the steps and options to create an alert definition or to start an operation

     

     

    Knowledge prerequisite: HTHM, JavaScript, REST principles (perhaps Java to extend the REST api if needed)

    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

    Notes:

     

    Implement an RHQ agent in Python

     

    Status: Proposed

     

    Summary of idea: Write a RHQ-agent in Python and make it interface with Matahari to pick up metrics that are provided by Matahari from Fedora or RHEL systems. The agent would talk to the RHQ server via the REST api and push metrics to RHQ etc. This agent will not implement the full functionality of the RHQ java agent.
