test(reader): cover open(uri, registry) via default-client seam#118
Merged
Conversation
#117's unit test threw before the delegation completed, so JaCoCo's end-of-line probe never fired and new-code coverage stayed at 50% (JaCoCo marks an always-throwing line as missed). Make the shared default HttpClient a package-private non-final seam so a unit test can substitute the mock fixture used by VortexHttpReaderTailFetchTest and drive the two-arg overload to a normal return — now the probe fires and the line is covered. Production never reassigns the field. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
