VoLTE in the news!!

T-Mobile Czech Republic started testing VoLTE technology, that is IP telephony over LTE. A nice article was published about it in the Czech news (see [1] for an English summary). VoLTE should be generally available for customers from January!

Why didn’t you tell me!

Here comes a testing focused article after a series of technical blogs! It is based on experience with projects managed through waterfall processes and it continues the series about tackling test complexity.

It is about a luxury that we so often ask for and we often don’t have in testing: to be involved early in the product development process. What does it mean actually to be involved early in the process? Why is it so important? And how does it help tackling test complexity anyway?

PrintEngine Yard is a platform as a service (PaaS) company that focuses on deployment and management of Ruby on Rails, PHP and Node.js servers in order to provide to customer a quick and simple way to deploy applications.

Knowing your subject

This article follows-up with the series of  articles about tackling test complexity, adding a view on the importance of product knowledge, when coping with the complexity of testing. Let’s assume that you understand already, who your customers are;)

I managed testing of a large integrated suite of software products on one of my past projects. Each product had its years of individual history already, when the decision was made to release them as a suite. And each of them was quite complex on its own, even without considering integration with other products. The number of installation issues reported by customers started increasing to an unacceptable level after a couple of years of the products suite’s existence. The whole engineering organization became concerned about the issue. First hypotheses about the cause assumed that the released installer was defective or that the product documentation was unclear. These were not proven however. So, we decided to conduct a profound root-cause analysis.

Missing the forest for the trees

Understanding customer needs for being able to do good testing sounds like commonplace that doesn’t need a special discussion. And testing projects often omit to discuss them indeed. Testing teams often start their project involvement with reading functional (or non-functional) specifications, skipping the customer view. I’m still mentioning it on the first place in the introduction of approaches to tackle testing complexity.

How to test your OpenDJ plugin

A problem you might face while extending the OpenDJ functionality with a plugin is to develop proper unit tests. OpenDJ comes with a set of tools to facilitate the testing, but since they are tightly integrated within the build framework, you might find it difficult to execute your unit tests from outside of the framework. This article will try to give you short guidelines on how to integrate and execute your tests.

Tackling complexity

Software complexity is one of the most significant challenges thatcomplexity and testing a software tester may face. Testing software that is complex usually requires a breadth of knowledge and experience. The goal that the tester needs to accomplish with regards to complexity is: to test the software in a reasonable time and at a reasonable cost.

As an example, think about ways to test upgrades of a database system with the following support matrix that gives altogether billions of combinations to test. Can this test scope be reasonably covered? Maybe. Let’s see several techniques that can help addressing complexity.

Methodoligst vs. Terrorist

Do you know the joke? “What’s the difference between a methodologist and a terrorist? Well, you can negotiate with a terrorist.”. It was perhaps more true for terrorists of the 20th century than those of the 21th, but you get the point. We met a “methodologist” the other day and that gave me the impulse to write this blog.
