명시적 동일 시각의 DTEND를 검증하십시오.

현재 테스트는 서로 다른 시작·종료 시각만 검증합니다. convert_non_all_day_event_without_dtend는 DTEND 누락 분기만 검증합니다. 따라서 명시적 DTEND가 DTSTART와 같은 입력에서 종료 시각이 다시 변경되면 테스트가 통과할 수 있습니다.

별도 테스트에 dtstart("20260818T093000") 및 dtend("20260818T093000")을 설정하고, 두 시각이 모두 2026-08-18T09:30인지 검증하십시오.

학습 내용 근거: 새 중요 로직에는 집중 테스트가 필요합니다.

convert_non_all_day_event_without_dtend와 별도로 dtstart와 dtend를 모두
20260818T093000으로 설정하고, 변환 결과의 시작 및 종료 시각이 모두 2026-08-18T09:30인지 확인하십시오.
