If something is testable, it can be tested — you can actually check whether it is true, whether it works, or how good it is. The word is most at home in science and in computing.

If something is testable如果一個東西是testable（可檢驗的）, it can be tested就代表它是可以被檢驗的 — you can actually check whether it is true, whether it works, or how good it is你真的可以去確認它是不是真的、有沒有用，或是好到什麼程度。The word is most at home in science and in computing這個字最常出現在科學和電腦領域。

A scientist says an idea is testable when you could design an experiment that would show it right or wrong; an idea that no experiment could ever touch is not testable, however interesting it sounds. Programmers say code is testable when it is written in a way that lets you run automatic checks on it easily.

A scientist says an idea is testable科學家會說一個想法是testable, when you could design an experiment that would show it right or wrong只要你能設計出一個實驗來證明它對或錯; an idea that no experiment could ever touch is not testable一個沒有任何實驗能碰得到的想法就不算testable, however interesting it sounds不管它聽起來多有趣。Programmers say code is testable程式設計師會說程式碼是testable的, when it is written in a way that lets you run automatic checks on it easily如果它寫的方式能讓你輕鬆對它跑自動化檢查的話。

Teachers use it too, about what can be examined. It is a formal word — you would not use it about the everyday sense of 'testing' the soup.

Teachers use it too老師也會用這個字, about what can be examined用來說什麼東西可以被考試檢驗。It is a formal word這是個正式的字 — you would not use it about the everyday sense of 'testing' the soup你不會拿它去講「嚐嚐看湯」那種日常意義的testing。

Note the quiet judgement inside it: calling a claim 'not testable' is often a polite way of saying it is not worth arguing about, because nothing could settle it.

Note the quiet judgement inside it要注意這個字裡藏著一種悄悄的評價: calling a claim 'not testable'把一個說法說成'not testable' is often a polite way of saying it is not worth arguing about常常是委婉地在說這件事根本不值得爭論, because nothing could settle it因為沒有任何東西能夠裁定它對錯。
