Teaching Test-Driven Development and Object-Oriented Design by Example

Test-driven development is an effective industrial practice. As educators of future software engineers, we need to effectively teach students test-driven development. Unfortunately, this topic is usually taught in a theoretical way. Students hardly use this approach in their projects. In this paper, we present a simple software development workflow that seamlessly integrates requirements refinement, object-oriented design, and test-driven development. A step-by-step live-coding demonstration which resembles test-driven development tasks students will face in the industry is also provided. By adopting the workflow and exemplary project in a programming class, we hope this provides students with some hands-on experience, thus helping develop good habit of programming.
