A testing strategy outlines your approach to unit, integration, and end-to-end tests tailored to your project's size and goals. Start by specifying your language, project scope, and coverage targets to generate a structured plan that includes test templates, tooling recommendations, and implementation steps for JavaScript/TypeScript, Python, or Go.

Unit testing validates individual functions in isolation; integration testing checks how components work together; end-to-end testing verifies entire workflows from user perspective. Each serves distinct quality goals and requires different frameworks and coverage metrics across your testing infrastructure.

Improving test coverage means identifying untested code paths and adding tests systematically. Establish a baseline coverage metric, prioritize high-risk areas, apply coverage strategies specific to your codebase structure, and leverage framework tooling to track progress toward your target percentage.

Yes, this Skill provides framework and tooling guidance specific to JavaScript/TypeScript, Python, and Go. Each language has recommended testing frameworks and CI pipeline configurations, allowing you to apply consistent testing principles across polyglot codebases.

Debugging failures involves isolating the root cause through test logs, assertion details, and environment state. Apply structured debugging practices and leverage language-specific testing tools to identify whether failures stem from code logic, test assumptions, or infrastructure setup.

CI pipeline tooling automates test execution on code changes and reports results. This Skill recommends frameworks and tools aligned with your language and project scale, helping you configure automated testing that catches regressions before deployment.
