investigating software

Earlier this year Boeing 787 maintenance engineers were given some new instructions by the FAA (The US government's: Federal Aviation Authority). They were informed that if the airplane's electrical generators were left running for 248 days, they would enter the fail-safe mode.  In plain English: they will stop producing electrical power. This short video looks into why that might be and how this information can help us to test our software. The FAA directive is available on their website . A Guardian article: Boeing 787 bug could cause 'loss of control' on Dreamliner

In many of my clients, more effort is spent on 'test automation' than on other forms of testing or quality assurance. That can be the right choice, for example, I worked on a Data Warehousing project where we needed to write some test automation before we could test the data and its processing. Many other projects in different technology areas also spend a lot of time on their test automation. To be precise, they spend an increasing amount of time fixing & maintaining old 'tests' and 'frameworks'. There are great tools around to help us write these automated checks quickly. But as with many software systems: maintenance, in the long term, is where the time and money goes. That is why I'm surprised we don't use short term automation more. We have the skills. One good example of short term automation is Bug Automation . A simple script / executable that recreates or demonstrates a bug. This isn't a new idea, I've been doing it for year

I now cover this issue in more detail in my podcast ! The EPA (The US government's Environmental Protection Agency) recently issued Notice of Violations regarding the emissions from Volkswagen cars. Volkswagen is actually a group of brands, therefore the Notice affects other cars such as Audi, Porsche and Skoda. A lot of the focus has been on what was going on in Volkswagen, for example who knew what was being done? Did the VW testers know? Did they pass the details on etc. What interests me is the wider issue of how this could have been possible for so long?  ( Since 2009 )  If so many cars were affected and for so long, why didn’t we hear about this sooner? Why isn’t there a team of people assigned to finding this stuff out... Oh wait, there is... In the UK these emissions tests are governed by the Vehicle Certification Agency , answering to the Department of Transport. One might expect the manufacturer to be less inclined to investigate the cars emissions, after-all te
