What problem does it solve?

Intermittent and non-deterministic test failures caused by timing issues, race conditions, shared state, resource leaks, or environment-specific behavior that make test suites unreliable in local development or CI pipelines.

Core Features & Use Cases

• Identify flaky tests through repeated runs and CI log analysis and classify root causes (timing, order, environment, network).
• Replace arbitrary sleeps with condition-based waits, enforce proper async/await usage, and apply Playwright/Vitest best practices to remove timing dependencies.
• Improve test isolation by resetting state, cleaning resources, mocking network/time, and recommending deterministic patterns for concurrent operations; useful for Playwright end-to-end tests and Vitest unit tests.
• Debugging aids such as adding logs, screenshots, traces, and running tests in isolation or with retries as a last-resort mitigation.

Quick Start

Diagnose the intermittent test by running it repeatedly, identify missing waits or shared state, replace sleeps with condition-based waits or mocks, and verify the fix by re-running the test 50+ times in CI.
