Duration Trends
Duration Trends track how individual test execution times change over time. A test that suddenly doubles in duration may indicate a performance regression, even if it still passes.
How It Works
Section titled “How It Works”The platform compares each test’s current duration against its baseline — the duration from the most historical run 10 commits ago. The difference is displayed as a trend indicator in the tests table.
| Trend | Meaning |
|---|---|
| ↑ +500ms | Test got slower by 500ms compared to baseline |
| ↓ −200ms | Test got faster by 200ms |
The tests table can be sorted by the Trend column to surface the tests with the largest duration changes. This helps you catch Performance regressions.
