Phase 03 Plan 03: Expanded Test Coverage Summary

9 integration tests covering aggregator edge cases (UDP timeout, PID inheritance, rate calc) and CLI/live filtering logic

Performance

• Duration: 1 min
• Started: 2026-03-22T04:52:21Z
• Completed: 2026-03-22T04:53:45Z
• Tasks: 2 of 2
• Files modified: 1

Accomplishments

• 9 new tests added to pipeline_test.rs (total now 13)
• Aggregator edge cases tested: UDP idle timeout, PID=0 inheritance, rate calculation, empty table, multi-protocol coexistence
• Filtering logic tested: port filter, PID filter, tcp_only filter, live text filter
• All 13 tests pass on macOS without root
• Human verified on Linux VM: CSV logging, man page, --help, all tests pass

Task Commits

Each task was committed atomically:

1. Task 1: Expand pipeline_test.rs with aggregator edge cases and filtering tests - 20e4fc6 (test)
2. Task 2: Human verification of Phase 3 deliverables on Linux VM - approved (human-verify, no commit)

Files Created/Modified

• tcptop/tests/pipeline_test.rs - Added 9 new tests (280 lines) covering aggregator edge cases and filtering logic

Decisions Made

• Used thread::sleep(6s) for UDP idle timeout test -- slow but proves the real 5-second timeout behavior works correctly

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Phase 3 complete -- all output, documentation, packaging, and test coverage delivered
• Human verified on Linux VM: CSV logging, man page, --help, and full test suite all confirmed working
• Phase 4 (macOS backend) can proceed when ready
