jUnit6, part 5: State Saving When Running Repeating Tests

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 […]

jUnit 6, part 3: parametric testing external file

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 […]

Automated Grading of Python in VPL using Unit Tests

A few of my colleagues here at YorkU have expressed an interest in using Python with Virtual Programming Lab on our Moodle-based eClass Learning Management System. I don't have a lot of Python experience, having only really used it for some data processing and toy embedded system demonstrations in the past. So I adapted the […]

Unit Testing a Question Bank

I'm working on question sets for introductory programming classes in languages like Java, C and Matlab, with a possibility of extending into other commonly-used languages (in our department) like Python and Verilog. The idea is that these questions could be deployed into a protected lab test or an open in-class "flipped homework" environment. Key to […]

Automated Student Evaluations in C (part 5)

This is the fifth in the series of postings on automated grading in C. Here, I've modified the VPL exercise to include four possible flowcharts that the students can implement, but the particular flowchart now get assigned to the student based on the time of day. The VPL output (both "run" and "evaluate" looks like […]

Automated Student Evaluations in C (part 3)

This is the third post in the series on evaluating student assignments in VPL with C and unit testing. We're targeting using VPL on Moodle / eClass. Specifically, the bash scripts are based on the fantastic work of Smith College professor emeritus, Dr. Dominique Thiébaut. He wrote about his VPL work here and while his […]

VPL: Simple C Assignment with Unit Testing

August 2021 Background Here, we're going to apply ThrowTheSwitch's Unity unit test framework to C programs. The test framework is available on GitHub. Three files need to be downloaded from the GitHub. There are a few more files that need to be developed within VPL to make it work, and those are described below. We're […]
