Machine learning Testing a Moving Target: How Do We Test Machine Learning Systems?

Most machine learning systems are based on neural networks, or sets of layered algorithms whose variables can be adjusted via a learning process. These types of systems don’t produce an exact result; in fact, sometimes they can produce an obviously incorrect result. So, how do you test them? Peter Varhol tells you what you should consider when evaluating machine learning systems.

Mob testing group Amplified Learning with Mob Testing

Just like with mob programming, mob testing is all about a group of testers coming together and collaborating. A lot of our testing knowledge is tacit—it’s in our heads, built from our years of experience. With the combined experience of everyone in the group, we get the best possible approaches to the testing task at hand.

Testing on mobile devices Demystifying Mobile Testing: Critical Thinking Prevails

There are so many testers who think mobile testing is completely different from other types of testing. But there is no need to totally shift their testing paradigm and strategy; mobile testing is not that different after all. This article details the commonalities and differences in testing mobile applications and how lessons learned from testing other applications can be applied to mobile as well.

Message indicating a user's session will time out Testing a User Session Timeout

Some situations and applications display a timeout message to the user to indicate the session has timed out. In other cases, the timeout takes place behind the scenes with no notification to the user. These situations will require an extra level of testing and thought to predict potentially troublesome user workflows. This article looks at both situations and how to test them.
