Intel Blog: The Right Mindset and Toolset for Testing

I have a two-part series (one, two) on testing posted on my Software Evangelist blog on the Intel Developer Zone.  This is a long piece where I get back to the interesting question of how you test things and the fact that testing is not just the same as development.  I call the posts Mindset and Toolset

Intel Blog: Testing and the ESA Schiaparelli Lander

It is really sad that the European Space Agency (ESA) lost their Schiaparelli lander last year, as we will miss out on a lot of Mars science. From a software engineering and testing perspective, the story of why the landing failed  rather instructive, though. It gets down to how software can be written and tested to deal with unexpected inputs in unexpected circumstances. I wrote a piece about this on my blog at the Intel Developer Zone.

UndoDB Recording during Automatic Testing

undo-logoUndoDB is an old player in the reverse debugging market, and have kept at it for ten years.  Last year, they released the Live Recorder record-replay function.  Most recently, they have showed an integration between the  recorder function and Jenkins, where the idea is that you record failing runs in your CI system and replay them on the developer’s machine.  Demo video is found on Youtube, see https://www.youtube.com/watch?v=ap8552P5vss.

Intel Blog: Wind River Using Simics to Test IoT at Scale

intel sw small This really happened last week, but I was in the US for the DAC then.  I did another blog on Intel Software blog, about a white paper that Wind River put out about how they use Simics internally. The white paper is a really good set of examples of how Simics can be used for software development, test, and debug – regardless of how old or new the hardware is.  It also touches my favorite topic of IoT simulation and scaling up – Wind River is actually using Simics for 1000+ node tests of IoT software!   Read on at https://blogs.intel.com/evangelists/2016/06/06/wind-river-uses-simics-test-massive-iot-networks/

In Defense of Testing and Testers

opinion I have been thinking about the role and prestige of testing for the past several years. Many things I have read and things companies have done indicate that “testing” is something that is considered a bit passe and old-school. Testers are dead weight that get into the way of releases, and they are unproductive barnacles that slow development down. Testers can all be replaced by automatic testing put in place by brilliant developers. The creative developer types are the guys with the status anyway. I might be exaggerating, but there is an issue here. I think we need to be acknowledge that testers are a critical part of the software quality puzzle, and that testing is not just something developers can do with one hand tied behind their back.

Product Holes: Tesla Roadster & iPhone 4

Continuing on the thread from my previous post about the testing of products that fail to find problems that become obvious to (some) users after a very short time, I just read an article (in Swedish) about how the famed Tesla roadster cars behaved when they were confronted with Scandinavian winters.
