Successfully used testLoadData for a number of test classes for "regular" Sobjects. Have seen references to Stub Api Mocking Framework for one method to create test records for Big Objects in Apex but seems pretty advanced.
Is there a way to use the Static Resource and use
Test.loadData(..) as documented here to add Big Object records for test classes?
TestloadData(BigObjectName.Sobjecttype, 'Filename') does not seem to be working. Getting error:
Unknown field: xyz
