Software Testing News Sep 2022 incl. NHTSA & Tesla

With October looming, today we look back at key updates in testing from this month. Software Testing News Sep 2022 features an article on more efficient modelling to test software updates from the University of Texas at Arlington. We then move on to a piece about Tesla adding crash test code into vehicle software. Finally, we look at the most common software bugs discovered during testing in 2022.

UTA Seeks to reduce testing times

This article is on valuable work from the Computer Science and Engineering (CSE) Department at UTA.

The University of Texas at Arlington received a 3-year, $490,000 grant to explore testing software updates without testing unchanged parts of the code. The grant from the National Science Foundation allowed Allison Sullivan, assistant professor in the CSE, to carry out the work. She will use modelling software called Alloy to focus on 3 ways of interacting with a model: Writing, testing and synthesizing.

The objective? To simply run a model on a specific change, potentially reducing testing time from several hours overnight to around 1 hour.

Did Tesla add code into its software?

Repairer Driven News looks at reports of Tesla adding special codes related to crash testing into its vehicle software.

The National Highway Traffic Safety Administration (NHTSA) is looking into the reports. The codes may relate to crash testing with auto safety agencies. Speculation on this was triggered when a Tesla software decoder named green took to Twitter:

Tesla just added ANCAP support in their code. This is in addition to already existing "I VISTA" (Chinese testing grounds), EuroNCAP and Korea NCAP

One wonders why do it (they also give testing houses one-off builds with the testing house in the name (with tweaked settings?) )

Most common bugs found in 2022

Robotics & Automation News published this piece on the year’s most common bugs just yesterday.

The article is well worth a read, with the most common errors found during testing in 2022 as follows:

Incorrect / incomplete functionality
Performance issues
Security issues
User interface problems
Compatibility issues
Loss of data
Memory leakage
