Flaky PTY/pexpect tests in ytnova are often caused by timing races between input, redraws, prompts, and filesystem state. This Skill provides a structured approach to reproduce, identify, and stabilize these races by introducing deterministic synchronization and short, intentional timeouts.
Create a minimal reproducible failing test path and run with deterministic waits to reproduce and stabilize the failure.

Flaky pexpect tests occur when timing races exist between input events, UI redraws, prompt transitions, and filesystem state changes. Replacing blind sleeps with explicit synchronization checks resolves these intermittent failures.
Fix flaky PTY tests by replacing blind sleeps with explicit waits, adding state assertions, and constraining timeouts. Create a minimal reproducible path and verify stability through repeated reruns across timing variations.
The best way to stabilize interactive terminal tests is introducing deterministic synchronization and short, intentional timeouts. This replaces non-deterministic blind sleeps with explicit waits for prompt transitions and redraws.
Yes, this approach explicitly handles race conditions involving filesystem state changes. Using state assertions and explicit synchronization checks stabilizes interactive terminal workflows affected by filesystem timing.
You should not use blind sleeps when testing interactive terminals, prompts, or redraws, as they cause timing races. Replace them with explicit synchronization checks and state assertions to ensure reproducible runs.
