Can it help stabilize flaky tests?

Yes, it includes specialized strategies for identifying non-deterministic failures and implementing robust waiting mechanisms and retry logic.

Does it support Page Object Model (POM) refactoring?

Absolutely. The skill provides standardized templates and logic to extract repeated test actions into maintainable Page Object classes.

Which E2E frameworks are supported?

The skill is primarily optimized for Playwright and Cypress, offering specific patterns and best practices for both ecosystems.

How does the confidence scoring system work?

It evaluates the quality of evidence, pattern matching, and context to assign a score (0-100). High scores allow for automated fixes, while lower scores prompt for user verification.

Security & Testing

Diagnoses and resolves end-to-end testing failures in Playwright and Cypress using a structured classification and confidence-scoring system.

This skill provides a comprehensive workflow for debugging and fixing E2E test failures by categorizing errors into specific types like timeouts, selector issues, and network interruptions. It utilizes a sophisticated confidence scoring system to evaluate proposed fixes and offers domain-specific guidance on Playwright and Cypress best practices. Whether dealing with flaky tests, fragile selectors, or complex navigation flows, this skill helps developers implement stable, production-grade testing patterns like Page Object Models and automatic retries.
