Visualization for Effective Testing and Learning
summary
Visualization of helsenorge.no (170M visits in 2021, ~5M users) converts system diagrams into concrete test counts: a three‑level GDPR model becomes a GDPR state machine that yields 12–24 transition tests; an attribute-based access model becomes an Access Control Tree with 15 scopes (15 positive checks, 105 negative scope pairs) and a full 7‑attribute model that expands to 66 scopes and >2,000 pairwise negative tests. Abstract tests map to code and run as 700 automated tests daily, with an explicit focus on negative tests.
