Test Oracle
http://en.wikipedia.org/wiki/Oracle_(testing)
以前看到這個術語, 不知道他是什麼意思, 也沒花時間出查, 只是略過而已.
想說它應該是指測試時所要用到的資料吧, 因為看到是oracle, 或許應該跟資料庫有關, 後來真的動手去查了一下, 才發現自己還真的很無知
在wiki說, test oracle是指測試人員確認測試是否通過的方法或機制. 常見的方法有哪些呢:
- specifications and documentation
- other products (for instance, an oracle for a software program might be a second program that uses a different algorithm to evaluate the same mathematical expression as the product under test)
- an heuristic oracle that provides approximate results or exact results for a set of a few test inputs
- a statistical oracle that uses statistical characteristics
- a consistency oracle that compares the results of one test execution to another for similarity
- a model-based oracle that uses the same model to generate and verify system behavior
- a human being's judgement (i.e. does the program "seem" to the user to do the correct thing?)
此外它還附了很多參考文件, 有興趣大家可以去看看
