Set CoverageSignal.status = "unavailable" + - Set metrics to None + - Do NOT generate alerts (no valid data) + - Log error for operations team + - Previous snapshot remains cached for dashboard (shows stale state) + - Retry on next test run +``` + +#### Scenario 2: Partial Coverage (Some Files Missing) +``` +Condition: Coverage tool produces output but some files weren't analyzed +Handling: + - Set CoverageSignal.status = "partial" + - Include available metrics with lower confidence + - Generate alerts but mark with "partial_data" flag + - Include caveat in alert: "Based on incomplete coverage data" + - Recommend re-running tests if critical files are missing +``` + +#### Scenario 3: First Measurement (No History) +``` +Condition: First test run, no baseline for regression comparison +Handling: + - Do NOT generate regression alerts (no previous measurement) + - DO generate below-threshold alerts (absolute rule) + - Store snapshot for future baseline comparisons + - Trend direction = "unknown" (need min 3-5 measurements) +``` + +#### Scenario 4: Module Path Changes +``` +Condition: Module was renamed (src/old_module → src/new_module) +Handling: + - Query both old and new paths for historical data + - Treat as separate modules (different scope_id) + - Alert on below-threshold for new module (no history yet) + - No regression detected (no direct predecessor) + - Document module rename in alert notes +``` + +### Measurement Noise and Flakiness + +Coverage measurements can fluctuate due to test flakiness and natural variance: + +#### Natural Variance (0.5-2%) +``` +Causes: + - Test flakiness (failing/passing non-deterministically) + - Timing-dependent code paths + - Platform-specific behavior (OS, Python version) + +Handling: + - Ignore variance < 0.5% (treat as "no change") + - Require 5+ consecutive measurements before declaring trend + - Use 7-day rolling average for smoothing (not raw daily value) + - Only escalate to severity if trend persists multiple days +``` + +#### Extreme Outliers (e.g., -20% in one run) +``` +Causes: + - Infrastructure issue (test runner error) + - Corrupted coverage data + - Major test suite failure + +Handling: + - Detect outliers: values > 3σ from rolling mean + - Flag as "anomaly" in alert + - Include only in history if confirmed by next measurement + - Alert with "investigate_infrastructure" recommendation +``` + +#### Coverage Tool Version Changes +``` +Condition: Project upgrades coverage.py from 6.0 to 7.0 +Handling: + - Coverage calculation may change (e.g., branch calculation) + - Historical data remains valid but not directly comparable + - Store "source_version" in CoverageMetricsSnapshot + - Apply version-specific normalization if needed + - Document change in alert notes +``` + +### Threshold Edge Cases + +#### Boundary Conditions +``` +Thresholds: minimum=80%, warning=85%, target=90% + +Test case: coverage = 80.00% + - Does coverage = 80% trigger alert? + - Decision: No (≥ threshold_min, not < threshold_min) + - Use consistent comparison: current < threshold (not <=) + +Test case: coverage = 79.99% + - Result: Triggers alert (just below threshold) + +Test case: coverage = 85.00% + - Does this trigger warning alert? + - Decision: Warning is informational (not blocking) + - Only below-threshold alerts block merges +``` + +#### Very High Thresholds (>95%) +``` +Risk: Setting minimum=95% is impractical + - Code will nearly never reach 95% statement coverage + - Constant false alerts → alert fatigue + - Example: some branches naturally untestable (error handling) + +Recommendation: + - Maximum practical minimum: 85-90% for critical modules + - Use branch coverage (stricter) rather than statement (easier) + - For untestable code, use pragma: # pragma: no cover +``` + +#### Very Low Thresholds (<50%) +``` +Risk: Minimum < 50% defeats purpose of alerting +Recommendation: + - Minimum < 50% only for exceptional legacy code + - Include exemption reason in config comments + - Plan migration path to higher threshold +``` + +### Time-Series Continuity + +#### Gaps in Measurement History +``` +Scenario: No test run for 5 days (deployment freeze) +Handling: + - Trend analysis skips days without measurements + - Compute slope using only available data points + - Projection accuracy lower (sparse data) + - Continue alerting when test runs resume +``` + +#### Timezone and Clock Skew +``` +Handling: + - Store all timestamps in UTC (never local time) + - Measurements from different timezones normalized to UTC + - Clock skew: if measurement timestamp is in future, log warning + - Use duration (not wall-clock time) for trend calculations +``` + +#### Retroactive Data Updates +``` +Scenario: Coverage service corrects a historical measurement + Timestamp: 2026-06-01 10:00 UTC + Original value: 84% + Corrected value: 86% + +Handling: + -
