Output matching with a runner
During the year you’ll probably assign a lab for students to write code in one class and have a separate runner class. It’s pretty easy to do in ClassCube.

Why Write Code on Paper?
School is about to start up for students all over the United States. And for those that are taking a computer science course for the first time, they’ll learn that it’s not always just typing code into a computer. So why do we write code on paper? Many teachers and professors have their students write […]
Comparing output in a JUnit test
Output matching is a built in test type in ClassCube. The catch is that you may not always want to compare that the output matches exactly. Or, maybe you want to do your own comparisons. To do this you’ll need to create your own JUnit test and use the unit testing grade type. Fortunately, it’s […]
