What types of tests can this skill generate?

It is capable of generating unit tests for specific functions, integration tests for API endpoints, and end-to-end (E2E) tests for critical user flows.

Does it support languages other than English?

While the internal reasoning is performed in English, all user-facing outputs, reports, and summaries are strictly provided in Japanese.

How does this skill determine where tests are missing?

The skill analyzes the coverage/coverage-summary.json file after running your test scripts to identify any files that fall below the 80% coverage threshold.

Will it break my build if tests fail?

The skill includes a verification step that runs the newly generated tests to ensure they pass before finalizing the coverage report.

安全与测试

Analyzes project test coverage and automatically generates missing unit, integration, and E2E tests to reach an 80% coverage threshold.

The Test Coverage Booster skill helps developers maintain high-quality codebases by identifying gaps in test suites and filling them automatically. It executes backend and frontend test scripts, parses coverage reports, and targets files falling below the 80% coverage threshold. By generating comprehensive test cases for happy paths, error handling, and edge cases, it ensures project stability and robustness. Designed for international teams, it performs internal reasoning in English while providing all final reports and summaries in Japanese.
