unit-test

Table-driven tests in Go catch boundary errors by structuring test cases to cover nil, empty, single-element, and last-element scenarios. This approach surfaces off-by-one errors and mapping losses early through deterministic boundary checks and mutation-resistant assertions.

A killer case in Go unit testing is a specific test scenario designed to guarantee defect detection and prove test robustness. It targets common failures like race conditions and context cancellation handling to ensure your assertions are mutation-resistant.

You enforce coverage gates for a Go codebase by utilizing standard Go tooling and conventions to measure test coverage. This skill ensures coverage gates are met by focusing on table-driven tests, boundary checks, and killer cases across exported functions.

Yes, this Go unit testing approach handles race conditions and context cancellation by specifically targeting them in killer case design. It enforces deterministic boundaries and clear, mutation-resistant assertions to verify correct propagation and concurrency handling.

Yes, you can use this skill to test exported functions and interfaces in Go. It provides table-driven test scaffolding specifically for these components, ensuring mutation-resistant assertions verify concrete fields rather than just nil or error values.

You prevent mutation testing from passing your Go unit tests by writing mutation-resistant assertions that verify concrete fields. This skill focuses on boundary checks and killer case design to guarantee detection of common defects and prove robustness.
