Which programming languages and frameworks are supported?

The skill provides optimized patterns for Node.js/TypeScript (Vitest/Jest), Go (go test), Python (pytest), and Rust (cargo test).

Can I use curl or httpie for testing with this skill?

No, this skill strictly prohibits curl and httpie in favor of proper test frameworks to ensure tests are repeatable, assertive, and integrated into the project codebase.

Where does the skill store test results and evidence?

Test files are placed in standard project directories like /tests, while execution logs and coverage reports are stored in the .artifacts/ directory for review.

Does this skill verify database changes?

Yes, one of the mandatory patterns of this skill is to verify that the database state was actually modified as expected, rather than just checking HTTP status codes.

Security & Testing

Automates backend API verification using language-native test frameworks to ensure robust database and endpoint integrity.

The Backend Testing skill transforms Claude into a rigorous QA engineer by enforcing the use of industry-standard test frameworks over manual, non-repeatable curl commands. It provides standardized patterns for Node.js, Go, Python, and Rust to verify API status codes, response payloads, and database state changes. By mandating test execution and evidence collection before any task is marked complete, this skill ensures that backend implementations are production-ready and fully verified against real-world edge cases.
