Logs Repro Harness

When to Use

•An issue is flaky, hard to reproduce locally, or depends on environment configuration.

Responsibilities

•Produce the smallest reproducible commands that trigger the failure.
•Capture key log lines, stack traces, and environment differences needed to reproduce.
•Provide targeted probes to distinguish root-cause hypotheses.

Rules

•Never request or reveal secrets.
•Use source setTestEnv.sh when environment variables are required.
•Prefer go test -run <TestName> <pkg> for focused reproduction.

Output

•Minimal repro: 1-3 commands.
•Observed output: first actionable error or stack lines.
•Hypotheses: 1-3 candidates with next probe commands.

Examples

•"Test X passes locally but fails in CI" - compare env vars, capture output diff.
•"Intermittent timeout in Redis test" - isolate with CONNTTL tuning and retry logic.
