As the web increasingly becomes real-time, marketers and publishers need analytic tools that can produce real-time reports. As an example, the basic task of calculating the number of unique users is typically done in batch mode (e.g. daily) and in many cases using a random sample from the relevant log files. If unique user counts can be accurately computed in...

Unit Testing and Test Driven Development are a hot topics in the Flash community lately, especially on Twitter. A few weeks ago, after realizing how complex my F*CSS library was getting, I decided to go back and write FlexUnit test for the library in a hope to use TDD moving forward.

Functional Testing for RIAs on the iPhone

By Robi Sen
June 8, 2009

One of the greatest frustrations when building RIAs for mobile browsers such as the iPhone, Safari, Webkit for the Android and Palm, and even IE for Windows Mobile phones is the lack of functional testing tools. Yet if you are making a RIA that is complicated or used for critical work, it behooves you to develop some approach to testing that is not completely manual. Furthermore, if you are serious about performance, you need to make sure your application is working functionally so you can create performance profiles that reflect a solid working application.

Finding a sweet spot for crowdsourcing: uTest outsources software testing

By Andy Oram
December 2, 2008

The promise of peer production seems to reach everywhere these days, but harnessing it is quite a trick. uTest seems to have corraled all the necessary elements. Their business model can be described quite simply: uTest signs up freelance testers for participating software development firms, who in turn pay each tester for each bug found. Anyone who wants to try peer production in his own industry can get some tips by studying how uTest and a company with some similarities, TopCoder, found their sweet spots.

Automated Testing and You, Self-Help for the Flex Developer: Part 2

By Michael Labriola
October 19, 2008

In part one of this article, we demonstrated how to create some basic and simple unit tests using Fluint. Those work well for very basic situations, but even an average Flex application will use events and have asynchronous aspects. This article will build on the last and demonstrate how to test systems with these concepts in mind. You will learn to write unit tests that wait for events to occur before continuing and whose success or failure may depend on something that happens sometime in the future.

Automated testing and you, self-help for the Flex developer: Part 1

By Michael Labriola
October 16, 2008

Software developers are a lazy group of people. It’s true. It’s what makes us good at our job. We have an intrinsic need to find an easier, or at least faster, way to do things. Of course, we also tend to be a stubborn group of people. It’s rare that someone can change our mind, we usually need to experience something ourselves to understand why it matters. That’s what this series of articles is about. I will tell you the reasons that my team writes tests. I will tell you what we get out of it. However, I will also show you that the barrier to entry is small and that writing tests is something you can try without a big commitment.

Unit Testing with AsUnit

By Kelly Brown
September 3, 2008

AsUnit is an open source framework for unit testing in Flash. AsUnit provides a low level automated testing system that is your first line of defense for catching bugs in your application. The concept of unit testing has been around for a long time as part of the traditional Waterfall model of software development. However, it has gained in popularity recently as one of the main tenets of Extreme Programming. One of the tenants of Extreme Programming is that you write unit tests first and then your code. You also refactor code often as you add features. Unit tests help find errors quickly as code is refactored and can be used as part of regression testing to make sure the new code has not affected existing functionality.

For those of you who are Perl or PHP programmers and who also do heavy testing, there's an excellent chance that you've heard of TAP, the Test Anything Protocol. It's easy to implement, easy to parse, and is gaining in popularity. Because it's being implemented so widely, we've decided to form an IETF working group and we need your help.

Software Usability Testing for the Rest of Us

By Jochen Wolters
July 29, 2008

If you're a software developer and you honestly care about the user-friendliness of your software, it is not enough to simply guess which user interface works best for your application: you must _test_ your products with real users. A new usability testing tool for the Macintosh, called "Silverback," now makes user testing available even to those developers who have, so far, found the cost and effort associated with setting up a proper usability test lab forbidding.
