The idea comes from the boundary. Given that we have a set of test vectors to test the system, a topology can be defined on that set. Those inputs which belong to the same equivalence class as defined by the equivalence partitioning theory would constitute the basis. Given that the basis sets are neighbors, there would exist a boundary between them. The test vectors on either side of the boundary are called boundary values. In practice this would require that the test vectors can be ordered, and that the individual parameters follows some kind of order (either partial order or total order). == Formal Definition == Formally the boundary values can be defined as below:- Let the set of the test vectors be $X\_1,\backslash dots,X\_n$. Let's assume that there is an ordering relation defined over them, as $\backslash le$. Let $C\_1,C\_2$ be two equivalent classes. Assume that test vector $X\_1\; \backslash in\; C\_1$ and $X\_2\; \backslash in\; C\_2$. If $X\_1\; \backslash le\; X\_2$ or $X\_2\; \backslash le\; X\_1$ then the classes $C\_1\; ,\; C\_2$ are in the same neighborhood and the values $X\_1\; ,\; X\_2$ are boundary values. In plainer English, values on the minimum and maximum edges of an equivalence partition are tested. The values could be input or output ranges of a software component, can also be the internal implementation. Since these boundaries are common locations for errors that result in software faults they are frequently exercised in test cases. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Boundary-value analysis」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
