Back when I was a PhD student at McGill, our lab had a rule of thumb when it came to robot tests: if the robot can't repeat the test at least ten times then it can't do it. You can see this in Dave McMordie's thesis, in Ned Moore's thesis, in Neil Neville's thesis and […]
When developing a stand-alone Java program all by yourself, it's typically preferable to do so from an IDE. However, a lot of projects rely on automated compiling and testing and this is really best done from the command line. While you may be used to using jUnit from inside an IDE like IntelliJ, it can […]
Building on the second post on jUnit 6, here is a parametric unit test set up with an external CSV file: This file, test values.csv, has comments and a header line that is to be ignored. It can be included in an IntelliJ project. We assume that a Calculator class is available that contains an […]

Before getting into the import of CSV files for testing, let's look at two features that are useful for setting up a bank of tests. We'll assume […]

Now in its sixth release, jUnit makes a significant jump to eliminating support in anything before Java 17. When I got started with Java in 2020 most of the teaching material […]
