# Telemetry Integration Tests

Phase 72.5.1.14 adds `@v2/telemetry-integration-tests`, the automated
client-to-warehouse integration harness for telemetry.

`runTelemetryClientToWarehouseIntegration` posts a client `TelemetryEventBatch`
to `createTelemetryIngestionEndpoint`, verifies the accepted batch is queued on
`v2-telemetry-firehose`, wraps that queued batch in a Kafka stream envelope, and
executes `runTelemetryDataPipelineOnce` into a memory warehouse sink.

The test suite covers a standard client UI event, a
`v2.client.performance.sampled` event from `@v2/client-performance-telemetry`,
and a rejected invalid client batch that must not reach warehouse rows.

Targeted verification:

```bash
pnpm --filter @v2/telemetry-integration-tests run typecheck
pnpm --filter @v2/telemetry-integration-tests run test
python V2/ue/Tools/check-v2-telemetry-integration-tests.py
```
