@session Feature: Session CLI uncovered branches As a developer I want full branch coverage for session CLI commands So that edge cases are tested Scenario: session cli branch - _get_session_service constructs service when _service is None Given session cli branch the module-level _service is None When session cli branch I call _get_session_service with mocked container Then session cli branch a PersistentSessionService is returned Scenario: session cli branch - _reset_session_service sets _service to None Given session cli branch the module-level _service holds a mock When session cli branch I call _reset_session_service Then session cli branch the module-level _service is None again Scenario: session cli branch - create command catches SessionNotFoundError Given session cli branch a mock session service that raises SessionNotFoundError on create When session cli branch I invoke the create command Then session cli branch the exit code is 1 And session cli branch the output contains "Error:" Scenario: session cli branch - show command with no messages Given session cli branch a mock session service returning a session with no messages When session cli branch I invoke the show command for that session Then session cli branch the exit code is 0 And session cli branch the output contains "Session Summary" And session cli branch the output does not contain "Recent Messages" Scenario: session cli branch - show command with linked plan ids Given session cli branch a mock session service returning a session with linked plans When session cli branch I invoke the show command for the linked-plans session Then session cli branch the exit code is 0 And session cli branch the output contains "Linked Plans" Scenario: session cli branch - show command with long message content truncated Given session cli branch a mock session service returning a session with a long message When session cli branch I invoke the show command for the long-message session Then session cli branch the exit code is 0 And session cli branch the output contains "Recent Messages" Scenario: session cli branch - delete command aborted via confirmation prompt Given session cli branch a mock session service for delete When session cli branch I invoke the delete command without --yes and answer no Then session cli branch the delete is aborted Scenario: session cli branch - export command catches SessionExportError Given session cli branch a mock session service that raises SessionExportError on export When session cli branch I invoke the export command Then session cli branch the export exit code is 1 And session cli branch the export output contains "Export error:" Scenario: session cli branch - tell command with stream=True Given session cli branch a mock session service for tell When session cli branch I invoke the tell command with --stream Then session cli branch the exit code is 0 And session cli branch the streamed output contains the assistant response
