Using Line of Balance to Track the Progress of Fixing Trouble Reports
|
You are the project manager of a large project and testing is uncovering faults, trouble reports are starting to pile up and the release date is coming soon. Are they going to be fixed on time? What could you do to help? Are there any bottlenecks? Where should you assign more resources? Does this scenario sound familiar? Have you been there? This article will explain how you can answer these questions by using an old method called Line of Balance in a new way. .

Using Customer Tests to Drive Development
|
Like many agile software development teams, our team writes tests for each feature before the feature is actually developed. We’ve found many advantages to using tests to drive development, not only at the unit test level but at the functional, system and acceptance test levels. .

Quality Practices and Problems in Free Software Projects
|
Abstract—Free software and open source projects are often
perceived to be of high quality. It has been suggested that the
high level of quality found in some free software projects is
related to the open development model which promotes peer
review. While the quality of some free software projects is comparable
to, if not better than, that of closed source software, not
all free software projects are successful and of high quality.

An Agile Tool Selection Strategy for Web Testing Tools
|
Selecting a test automation tool has always been a daunting task. Let’s face it, just the thought of automating tests can be daunting! The selection of tools available today, especially open source tools, is positively dazzling. In the past several years, "test-infected" developers, not finding what they need in the vendor tool selections, have created their own tools. Fortunately for the rest of us, many are generous enough to share them as open source.

A Metric Leading to Agility

Nearly every metric can be perverted, since up- and down-ticks in the metric can come from good or bad causes. Teams driven by metrics often game the metrics rather than deliver useful software. Ask the team to deliver and measure Running Tested Features, week in and week out, over the course of the entire project. Keeping this single metric looking good demands that a team become both agile and productive.Read more...

A Performance Analysis of Secure HTTP Protocol
|
Data security plays an essential role in today’s web service. Secure HTTP (HTTPS) is one of the popular protocols to transfer sensitive data over the Internet. This paper shows how the security affects performance compared to HTTP. Based on our preliminary measurements, the average response time ranges from 0.1 to 5 seconds, and from 6 to 8 seconds, for HTTP and HTTPS, respectively. Our experiments also show that the HTTPS overhead mainly comes from clients other than servers. Read more...

A Few Words About Regression Testing

Suppose that you've tested a product thoroughly and found no errors. Suppose that the product is then changed in one area and you want to be sure that it still passes all the tests it did before the change - that the change didn't introduce any new defects. Testing to make sure the software hasn't taken a step backwards, or "regressed", is called "regression testing". Read more...
