The idea
Coverage you can actually see
Every team has test cases. Very few teams know where they are, whether they still match the product, or what they actually cover. The cases get written once, exported to a spreadsheet, and quietly go stale while the codebase moves on without them.
Vaettir treats test cases as living things: tied to the code and behavior they guard, current by default, and visible before something breaks instead of after.
What it does
Test cases that keep themselves honest
- One home for test cases — structured, searchable, and owned by the team instead of scattered across tools.
- Coverage that stays connected to what the product actually does today, not what it did when the case was written.
- A clear view of what's watched and what isn't, so the gaps show up before the incidents do.
The name
Why “Vaettir”
Named for the vættir, the old Norse land-spirits said to watch over a place whether anyone noticed them or not. Vaettir does the same for test coverage — the cases keeping watch over a codebase, visible before something breaks instead of after.
