A couple of weeks ago, I spoke at the RIA conference Web on the Piste 2008 on the topic of "Testing for Success".

Over the past few years, I've worked with many ColdFusion and Flex development teams. It has been interesting to see that there is more interest in test-driven development. However, a lot of times team leaders/company executives overlook the bigger picture and focus on just the details. And the lack of this larger context can lead to less effective/failed testing practices. My presentation this year was focused on presenting this bigger picture with focus on ColdFusion and Flex.

You can download the presentation here or view it at Slideshare.

By the way, for those of you who have not heard about Web on the Piste, it is a conference on Rich Internet Technologies that takes place every year in the beautiful Queenstown in New Zealand.

Adobe Devnet has a security advisory on the upcoming Flash Player 9 update. The advisory lists a few very important changes to the security model in Flash Player which can possibly impact your existing Flex and Flash applications. The changes are primarily to address the vulnerabilities of the earlier versions of Flash Player (9,0,115,0 and before).

There are four key changes that can possibly impact existing applications:

• A socket policy file will always be required for all socket connections
• A policy file will be required to send headers across domains (This will possibly affect some of the Flex apps that I work with)
• The allowScriptAccess default will always be "sameDomain"
• "javascript:" URLs will be prohibited in networking APIs, except getURL(), navigateToURL(), and HTML-enabled text fields
