Is this skill compatible with Maven build systems?

Absolutely. It includes specific standards for build integration, providing patterns for NPM and Maven to work together in automated CI/CD pipelines.

How does it handle test isolation?

It utilizes modern Cypress patterns like cy.session and custom navigation helpers to ensure each test case starts in a clean, predictable state.

Why does this skill prohibit branching logic in tests?

Prohibiting if/else or switch statements ensures tests are linear and deterministic, which prevents 'flaky' results and makes test failures much easier to diagnose.

Does this skill support console error tracking?

Yes, it implements a console-monitoring system with a zero-error policy, meaning any browser console error or unexpected warning will automatically fail the test suite.

Can I use this for non-CUI projects?

While the standards are optimized for CUI OSS projects, the best practices for test organization and reliability are applicable to any modern JavaScript testing environment.
