Graphical user interface (GUI) testing is a potentially problematic area because constructing effective test cases is more difficult than the corresponding application logic. The roadblocks to effective functional GUI testing are: Traditional test coverage criteria like "80% coverage of the lines of code" may not be sufficient to trap all the user interaction scenarios. End users often use a different user task interaction model than the one conceived by the development team. Functional GUI testing needs to deal with GUI events as well as the effects of the underlying application logic that results in changes to the data and presentation. The common methods for functional GUI testing are the "record and execute" script technique and writing test programs for different scenarios. In the "record and execute," the test designer interacts with the GUI and all the eve... (more)

Java Developer's Journal Exclusive: 2006 "JDJ Editors' Choice" Awards

The editors of SYS-CON Media's Java Developer's Journal are in a unique position when it comes to Java development. All are active coders in their "day jobs," and they have the good fortune in getting a heads-up on many of the latest and greatest software releases. They were asked to nominate three products from the last 12 months that they felt had not only made a major impact on their own development, but also on the Java community as a whole. The following is a list of each editor's selections and the reason why they chose that product. Joe Winchester Desktop Java Editor SwingLabs SwingLabs is an open source laboratory for exploring new ways to make Swing applications easier to write, with improved performance and greater visual appeal. It is an umbrella project for various open source initiatives sponsored by Sun Microsystems and is part of the java.net community... (more)

Installing Ruby on Rails and PostgreSQL on OS X, Third Edition

Over the past few years, I’ve helped you walk through the process of getting Ruby on Rails up and running on Mac OS X. The last version has been getting a lot of comments related to issues with the new Apple Leopard, so I’m going this post will expand on previous installation guides with what’s working for me as of January 2008. The following guide is how our development team at Planet Argon prefers to setup our development workstations During this installation, we’ll have what we feel is the optimal development stack for building Ruby on Rails applications with our favorite database server, PostgreSQL. Ready? Let’s get started… Phase One During this initial phase, we’re going to install the underlying dependencies that we’ll be building off of.

Our weapon of choice is still Ruby on Rails, the popular MVC framework. Out belief is that Rails makes certain types of tasks easy, and others laughably trivial. ... (more)

The 64KB Java Language Problem - Lesson Learnd from Using Rhino to Process JavaScript

This entry documents a few tips related to using Rhino JavaScript Engine to process JavaScript code. If you are using Rhino, you probably won’t run into the issues covered in this post during development or even testing. However, you are fairly likely to run into these issues after your system goes live. It would easily result in days or even weeks of soul searching (speaking from my personal experience:-)). Part of the problem seems to be the lack of documentation from the web. The other part of the problem is that the problem is rather a Java language problem(very convoluted). - Java limits the maximum method size to be 64KB. 1. JVM Byte Code Size Limit Problem On rare occasions, you will see exceptions like the followings from Rhino when processing JavaScript files: Exception in thread “main” java.lang.IllegalArgumentException: out of range index at org.mozilla...

Stax Networks Launches: Google App Engine For Java

Seattle-based Stax Networks launches this morning into private beta. Stax is offering a platform as a service product for Java applications - basically, the easiest way to think about it is Google App Engine for Java applications (or Heroku for Ruby on Rails applications)., Java is still extremely popular for business applications (Indeed has 64,000 Java job openings currently as well). Stax is built on top of Amazon EC2 and allows developers to create, text and deploy Java applications without having to build out their own physical infrastructure. For now Stax isn’t charging users at all. Eventually they’ll move to a model that charges for resources uses, similar to EC2 and other infrastructure platforms. If you want to try it out, create an account using the “techcrunch” invite code. The company was founded by Spike Washburn, Cold Fusion creator J.J. Allaire a... (more)
