targeted-testing

To run targeted tests for specific code changes, the skill selects and executes the most concise validation step, prioritizing smoke tests and focused test files over broad runs to minimize execution time.

The best way to validate code modifications quickly is to run the smallest relevant test suite, using local check scripts and targeted test files directly related to the changed functions to speed up the feedback loop.

Targeted testing identifies the optimal validation path by requiring knowledge of the changed files and the project's testing infrastructure to select the most efficient and relevant tests.

Yes, you can use this skill for local debugging as it prioritizes smoke tests and local check scripts to validate code modifications efficiently before resorting to full test suite runs.

You should avoid focused test suites and use a full validation run when the skill cannot identify an optimal validation path from the changed files, or when comprehensive validation across the entire project is explicitly required.
