My research on improving teaching and learning strategies of software testing in computer science education.



My Orcid ID is: 0000-0002-0680-4443.


I sometimes toot about my research on my Mastodon account about my research, but more often about other things that interest me, or that fill me with wonder.

Running / sports

Follow me on Strava! I like to go for a run now and then. It helps me to think and also to clear my mind. I often get my best ideas while working out, but I also tend to forget most of them immediately.

Testing day 2023

by Niels Doorn

On the Testing days 2023 I will give a talk about test modelling using an online web based modelling tool. This is the text for the program on the website.

Sensemaking in test modelling with TestCompass

In the dynamic landscape of software development, testing has emerged as the most commonly used technique for measuring software quality. Despite its significance, software testing often receives insufficient attention in computer science education, leading to suboptimal testing practices among students and graduates.

Teaching software testing is a complex intellectual activity for which students need to allocate multiple cognitive resources at the same time. A systematically developed body of knowledge of didactic approaches, effects of educational settings, and learning outcomes is lacking.

As a first step in determining how software testing education can be improved, we have studied the sensemaking process of students designing test cases using an online modelling tool. We continue this research by studying the approaches taken by test experts when designing test cases. By comparing students to these experts, we will know where the deficiencies lie for them and what we need to train them on. We can use this knowledge to develop instructional designs that can be used in different educational contexts.

To address this issue, the presentation will shed light on the intricate process of teaching software testing.

Key Highlights:

This presentation marks a significant stride toward bridging the gap between theory and practice in software testing education. Join us as we uncover valuable insights that will pave the way for a more effective approach to teaching this essential skill.
