@emdneto may I pick this up given there's been no activity for many months?

[sginji]

@emdneto it appears that this test was deleted in https://github.com/open-telemetry/opentelemetry-python/commit/3497e6662984edb345eaac4c4d3ac4872d438a55#diff-73d0e7899abf301636c4ce674f9d18cbebe6718a6a210c18161024d1663bf6aaL522-L527
