|
* Contract tests for the transaction apply-pipeline span constants.
|
|
*
|
|
* The span names and attribute keys in TxApplySpanNames.h are a cross-component
|
|
* contract: the collector spanmetrics connector aggregates on these exact
|
|
* strings (dimensions tx_type, ter_result, stage) and the Grafana
|
|
* transaction-overview dashboard queries them. A silent rename here would
|
|
* break per-stage metrics with no compile error, so these tests pin the
|
|
* literal values. They need no telemetry runtime and run in every build.
