handsontableSkill

test-writing-discipline

handsontable/handsontable/.claude/skills/test-writing-discipline/SKILL.md

Use when writing, fixing, or reviewing tests for any Handsontable change (unit, E2E, or wrapper), and whenever a test is red during feature work. Enforces that tests prove intended behavior – not just execute code, and never "green for the sake of green". Covers intent-first (write the test from the requirement, ideally before the code), deciding whether the code or the test is wrong when red (default: the code), the banned ways of faking green, write-the-failing-test-first, verify-with-a-real-run, no hollow assertions, not mocking the unit under test, and migrating broken legacy tests.
