TiDB Failpoint Test Runner

Overview

Follow this workflow before running package tests under pkg/.... -tags=intest,deadlock does not enable failpoints. Canonical command details live in docs/agents/testing-flow.md -> Failpoint decision for unit tests.

Workflow

1. Use docs/agents/testing-flow.md -> Failpoint decision for unit tests to decide whether the package needs failpoint enablement.
2. Run the matching command set from docs/agents/testing-flow.md:
   • Failpoint-enabled run when the package matches the failpoint checks.
   • Unit tests (/pkg/...) when it does not.
3. Keep the run targeted with -run <TestName>; for Bazel-specific variants, see the Bazel notes in docs/agents/testing-flow.md -> Failpoint-enabled run.
4. Record the decision evidence and exact test command in the final report.
