Field tests.

CKey is tested on rendered and simulated photos. These tests are how it gets tested in the real world: by anyone, with a printer and a phone. Every result is published here, good or bad.

How it works.

  1. Pick a test

    Each one checks a single claim and says why it matters.

  2. Print the sheet

    The test codes are drawn by the same CKey core as everything else here.

  3. Follow the steps

    Record what the test asks for, then grade it with its rubric: pass, partial or fail.

  4. Report it

    Here, with optional photos, or as an issue on GitHub. Both appear below.

The official suite.

Defined in the CKey repository as field-tests, which this page reads from directly, so the two never differ.
