+WARNING: Properties for testcases is not following standard JUnit XML schema.
+However, other consumers may support properties for testcases like [DataDog metadata through `<property>` elements](https://docs.datadoghq.com/continuous_integration/tests/junit_upload/?tab=jenkins#providing-metadata-through-property-elements)
