No task.wait

ErrorRoblox

small-rules/no-task-wait

Disallow task.wait() and Promise.delay(...).await() calls.

Rationale

Unit tests were taking ten billion years to run because of task.wait() calls scattered everywhere, each one actually sleeping. Promise.delay(...).await() does the same thing. Absolute nonsense in a test suite.

Advance your scheduler or wait for the actual condition instead of sleeping and hoping. The game code can use it fine, this is about keeping the test run from dragging.

Diagnostic Messages

noPromiseDelayAwait

Do not use Promise.delay(...).await() in tests. Advance deterministic schedulers or wait for the actual condition instead.

noTaskWait

Do not use task.wait() in tests. Advance deterministic schedulers or wait for the actual condition instead.
