 ## Tests
-| Test Path | Description |
-| ---- | ----------- |
-| [./src/durability-tests](src/durability-tests/) | Test that all the events created by the Analytics SDK end up as HTTP Requests, and that graceful shutdown does not result in events getting lost. |
-| [./src/perf-tests](src/perf-tests/) |  These tests confirm that performance has not regresssed relative to the old SDK or from the baseline (which a handler _without_ analytics).
