Test Methodology
Baseline: Established performance thresholds based on historical data
Current: Latest test execution times in milliseconds
Diff %: Percentage change from baseline (negative = improvement, positive = regression)
Threshold: Acceptable variance range (typically ±20%)
Status: Pass/fail status based on threshold compliance
Performance tests are run automatically and results are updated with each test execution. Tests marked as “disabled” are not currently being evaluated for performance regressions.
Understanding the Results
🟢 Within threshold: Performance within acceptable thresholds
🔴 Above threshold: Performance degradation beyond threshold
⚪ Disabled: Tests currently disabled for performance monitoring
The dashboard is sorted by execution time (slowest functions first) to help identify potential optimization targets.
