Resource Redirection in Spring Pet Clinic Application for Tomcat 7 and Cloud Platforms

In previous months I’ve been playing with various cloud platforms, learning the basics, what’s different and what not, between them and comparing with more ‘traditional’ developments.

When I start to work in a new framework or tool, I tend to use the same set of reference applications to start. Simple stuff for a simple start. With that I pretend to concentrate in  the specifics of the f/t at hand, without dealing at the same time with whatever idea I had and was building.

The first app, as you can see in previous posts, is the simplest of Spring+Hibernate use cases, CRUD on a simple, two-field entity. This one is good to start but too simple to be really representative o an actual development.

For the second iteration I work with Spring Pet Clinic reference application: an exemplar use of Spring Framework created by Spring team a few years ago. To my surprise, Pet Clinic didn’t work out of the box with the latest Tomcat release, and while looking at what was happening I found out a few things worth sharing about the greatest and latest Spring and Tomcat.

In this post I will walkthrough my findings with Pet Clinic and what enhancements I did to make it ready for 2012 and beyond.

First Steps with Heroku – The New-Old Boy in the Cloud

Since my previous posts about Java cloud platforms I wanted to expend some time with Heroku and compare with the others.

Heroku is a veteran among the cloud platforms, but it’s not until a few months ago that they launched a Java offering.

In this post I will share my experiences starting with Heroku and making an existing application to work on it.

Selenium in One Minute (Video)

For some time I’ve been willing to record and upload a short video showing how Selenium works, working in a grid with several computers/browsers and an Android table as well.

For this short demo I’ve used the Spring PetClinic reference application, tweaked to work with Spring 3.0.6 and Tomcat 7.0.22.

This short video is slightly above one minute long. Hope you enjoy it!

Test Automation with Selenium WebDriver and Selenium Grid – part 3: Continuous Integration

In part 1 in the series (read it here) I discussed about Selenium, the widely used tool for browser test automation, and I showed how easy is to setup a testing grid with multiple OS and browsers. In part 2 (read it here) I showed how to leverage WebDriver API to create and execute tests distributed across the grid that was created.

Now in part 3 I will show how to execute Selenium tests under a Continuous Integration process with Maven, Cargo and Jenkins, and how to gather code coverage metrics for those tests using Sonar and JaCoCo.

Test Automation with Selenium WebDriver and Selenium Grid – part 2: Creating and Executing Tests

In part 1 in the series (read it here) I presented Selenium, a widely known tool for browser test automation.

Starting with Selenium 2, the most important components from the suite are Selenium WebDriver and Selenium Grid. In part 1 I showed how easy is to setup a testing grid with multiple OS and browsers. Now in part 2 I will show how to leverage WebDriver API to create and execute tests.

Test Automation with Selenium WebDriver and Selenium Grid – part 1: Setting Up the Grid

For a long while I’ve been “dying to play” with Selenium (www.seleniumhq.org and code.google.com/p/selenium/). I’ve heard and read very good things about this tool from colleagues and from the blogosphere.

Selenium is, in short, an open source tool to automate web browser interactions. A primary use case is, of course, browser test automation.

Selenium has greatly evolved with time, specially since the 2.0 release when the legacy Selenium project merged with Google’s WebDriver. Nowadays, Selenium offers a wide range of programming languages supported to write the tests, an impressive browser compatibility list, the ability to record tests from user interactions and, above it all in my opinion, the ability to re-execute tests across a grid of machines with various operating systems, browser families and versions.

Although Selenium seems to be primarily chosen for functional/regression test automation, it’s also a great choice – precisely because of the grid feature – for cross-browser compatibility testing: ensuring in an easy, cost-effective way, that our web applications are usable in all sorts of operating systems and browsers.

In this and forthcoming posts in a short series I will share my experiences setting up a Selenium Grid, building some automated tests for a simple Spring application, re-executing them from Eclipse IDE and finally re-executing them in continuous integration (including code coverage) with Maven, Cargo, Jenkins, Sonar and JaCoCo.

Red Hat OpenShift: Freedom of Choice

1         Introduction

After we finished writing the post on VMware Cloud Foundry platform, it seemed natural to write a follow-up on Red Hat OpenShift. OpenShift is a Java-based Platform-as-a-Service (PaaS) offering from Red Hat, the ‘giant’ of Open Source Software with a well-deserved reputation that comes from a wide range of products including operating systems (Fedora, Red Hat Enterprise Linux), application servers / middleware (JBoss AS, JBoss ESB), frameworks (Hibernate, Seam) and tools (JBoss Tools, Arquillian).

As a PaaS offering, the ultimate goal of OpenShift is to reduce the effort needed to write and deploy highly scalable and highly available Java applications. Under your dedicated “application space” the platform components run to ensure your application is able to respond to user’s requests, but isolating your application code from the infrastructure and all the complexity usually associated with complex, distributed deployments.

Let’s jump into OpenShift!
