訂判斷及所需輸入

本例試驗要求 A 上十讀十寫。二十讀雖同樣二十次，沒有寫，並不相符。程序真的對本地集合執行讀寫，計兩類及涉及哪些鍵。

已填本地測試工作表
情況輸入 JSON
原例測試{"requiredReads":10,"requiredWrites":10,"requiredKey":"A","operations":[{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"},{"kind":"read","key":"A"}]}

跑所附比較

此處只核效能試驗輸入是否正確。重跑是順序執行，未量真並行競爭、吞吐或正式容量；配對了的材料仍要另跑並行試驗。

按邊界依據作判斷

一讀一寫 A 符邊界材料，A 最後1；同數量在 B，A 仍0，違所需共用紀錄條件。

  1. 訂讀寫組合及鍵範圍
  2. 真正重跑所附操作
  3. 同時對數量及涉及紀錄

試驗材料相符，本身不是效能結果。

可編輯邊界輸入及結果
條件輸入 JSON預期輸出 JSON
所需共用紀錄讀寫{"requiredReads":1,"requiredWrites":1,"requiredKey":"A","operations":[{"kind":"read","key":"A"},{"kind":"write","key":"A"}]}{"reads":1,"writes":1,"valueA":1,"testInputMatches":true}
數量相同但紀錄不同{"requiredReads":1,"requiredWrites":1,"requiredKey":"A","operations":[{"kind":"read","key":"B"},{"kind":"write","key":"B"}]}{"reads":1,"writes":1,"valueA":0,"testInputMatches":false}

原例二十讀，可支持所需讀寫試驗嗎？

查看參考答案

不能，寫是零而非十。總數相同未確立所需讀寫組合或鍵分布。
