condition-based-waiting

SKILL.md

Flaky tests often guess at timing with arbitrary delays. This creates race conditions where tests pass on fast machines but fail under load or in CI.

Core principle: Wait for the actual condition you care about, not a guess about how long it takes.

| Wait for event | waitFor(() => events.find(e => e.type === 'DONE')) | | Wait for state | waitFor(() => machine.state === 'ready') | | Wait for count | waitFor(() => items.length >= 5) | | Wait for file | waitFor(() => fs.existsSync(path)) | | Complex condition | waitFor(() => obj.ready && obj.value > 10) |

Úselo cuando las pruebas tengan condiciones de carrera, dependencias de tiempo o comportamiento inconsistente de aprobación/fallo: reemplaza los tiempos de espera arbitrarios con sondeo de condiciones para esperar cambios de estado reales, eliminando pruebas inestables de conjeturas de tiempo.
