MO4BCO01	Using BDD Testing in SKAO: Challenges and Opportunities	183
	V.L. Allan University of Cambridge, Cambridge, United Kingdom G. Brajnik IDS, Udine, Italy L.R. Brederode SKAO, Macclesfield, United Kingdom
	Defining what a system should do is one of the hardest parts of system design. Using Behaviour Driven Design (BDD) techniques can help, and also help define the tests needed to check that the desired behaviour is implemented. We describe the challenges and opportunities that arise when adopting these techniques, including both technical and social issues, and especially why in our case BDD techniques provide significant value. We present our pathway towards using BDD and the lessons learned. By trying to use BDD testing to run integration tests, it enabled the identification of gaps in the testing infrastructure, particularly the TANGO testing infrastructure, and gaps in developers’ understanding of the system design. This allowed SKAO to take steps to improve the tests, the infrastructure, and the design, by integrating BDD techniques into the full product development lifecycle and using them also for monitoring the development process and the quality of software products.

Defining what a system should do is one of the hardest parts of system design. Using Behaviour Driven Design (BDD) techniques can help, and also help define the tests needed to check that the desired behaviour is implemented. We describe the challenges and opportunities that arise when adopting these techniques, including both technical and social issues, and especially why in our case BDD techniques provide significant value. We present our pathway towards using BDD and the lessons learned. By trying to use BDD testing to run integration tests, it enabled the identification of gaps in the testing infrastructure, particularly the TANGO testing infrastructure, and gaps in developers’ understanding of the system design. This allowed SKAO to take steps to improve the tests, the infrastructure, and the design, by integrating BDD techniques into the full product development lifecycle and using them also for monitoring the development process and the quality of software products.
