test-isolation-validation

What problem does it solve?

This Skill eliminates the risk of undetected test regressions and hidden state leaks between tests that produce flaky, unreliable test suites and allow bugs to slip into production.

Core Features & Use Cases

• Regression Testing: Runs full test suites on both the main branch and feature branches to identify new test failures introduced by code changes.
• Isolation Validation: Executes tests in random order multiple times to detect state contamination between tests that causes inconsistent, flaky results.
• Use Case: For example, before merging a new user authentication feature, use this Skill to verify no existing login or permission tests break, and no test state leaks between session management and token validation tests.

Quick Start

Use the test-isolation-validation skill to run a full regression and isolation check on your current feature branch's test suite before merging to main.
