CI / test (push) Has been cancelled
Details

Browse Source 
Phase 4.2 (PR #12) and test coverage improvement (PR #13) independently
added overlapping test functions. Remove duplicates from PR #13 files:

- internal/dns/iterative_test.go: remove TestExtractNSNames,
  TestExtractNSNamesEmpty, TestIterativeQueryWithExchangeSuccess,
  TestIterativeQueryWithExchangeNilResponse, TestIterativeQueryWithExchangeTCPFallback
  (kept in roots_test.go and query_test.go from PR #12)
- internal/output/coverage_test.go: remove TestRRDataStringDefault,
  TestContainsString, TestCollectUniqueServerIPs, TestNewFormatterNilWriter
  (kept in stats_test.go and formatter_test.go from PR #12)
