Instead of batching based on the Resource pointer which is not guaranteed to uniquely identify common Resources, use the
String
method which is.Renames the external test package to be identified as the integration testing. This testing structure (the mock exporter) batches exported resources transmitted from the resource. This is needed as there is no guarantees that a batch will be exported in a single payload, therefore, it is not an ideal place to add resource batch testing for the exporter itself.
Add unit tests to ensure the Exporter is correctly batching spans by resource.
