Forty country/format combinations, 35,117 equivalence classes, and eight fields our API accepted but never wrote. Testing against the specification, not our own code.

A complete worked example: one prompt, one decision table, eight generated test cases with real data. Everything shown is output from an actual run.

A field report from our own products: we replaced 16 hand-written spec files with 117 decision tables and 1,981 data-driven cases, run by a single runner that reads the tables as data. Here are the numbers, the defects it surfaced — including two assertions we had written wrong ourselves — and the things decision tables do not solve.

Nanook now ships a Claude Code skill and slash command that generates complete equivalence class
tables from a test object description. Run
/createEquivalenceClassTable with a page name, API endpoint, or form — and get
a fully formatted Excel file with correct markers, formulas, and 100% CASCADE coverage.

Every software project needs test data. But how that data gets created — and how well it covers the things that matter — varies wildly. This article compares manual and automated approaches, with a practical comparison table and guidance on when to make the switch.

Equivalence class testing is a systematic technique that groups inputs into classes expected to behave the same way. This guide walks through the concept with worked examples, compares it with boundary value analysis, and shows how to automate the process with Nanook.

After years of quiet production use, Nanook is back with a refreshed website, new documentation, and a roadmap for 2026. Here is what changed and what comes next.
