fix

To fix a Go bug with a regression test, you first create a failing test that reproduces the specific failure, then implement the smallest possible code change to make it pass. Finally, you validate the fix by running go build and go test.

The minimal-change approach for bug fixing limits code modifications to only what is strictly necessary to resolve the failure. It enforces a regression-test-first workflow where a failing test is written before the fix, ensuring stability without introducing unnecessary changes.

Creating a failing test before fixing a user-reported bug involves writing a regression test that specifically captures the reported failure. You then implement the minimal fix and re-run go build and go test to confirm the bug is resolved and stability is maintained.

Yes, this TDD-driven bug fix workflow requires running go build and go test as part of its verification discipline. These commands must pass before merging any changes to ensure the minimal-change fix successfully resolves the regression test without breaking existing functionality.

Regression testing helps maintain momentum when fixing code by enforcing a strict test-first workflow and capping reattempts. By requiring a failing test before implementing a minimal fix and validating with go test, it prevents endless debugging cycles and ensures rapid, stable resolution.

You should use a regression-test-first workflow for bug fixing when addressing user-reported bugs or specific code failures. This approach ensures the bug is reliably reproduced before implementing a minimal-change fix, validating stability with go build and go test before proceeding.
