Talk:Boundary-value analysis

Number of cases

This article suggests the common example of using three test cases at a boundary.

I have some problems with this, as there is disagreement as to how many cases are actually useful. Beizer in Black-Box Testing gives a very strong (to me) argument that only two cases are needed, including going through the eight failure cases for a one dimensional boundary, and comparing whether three cases is better than two.

I am loathe to just change this article so as to use only two test cases per boundary, as I understand that many people don't like this reasoning. I was considering adding a new section, titled something along the lines of 'Alternate Approach'. To me that smacks of turning the page itself into a discussion (where I am assuming that this page is useful to someone who wants to know what BVA is, and see an example we don't necessarily need to drag them into a discussion). However I am more loathe to leave the article as is (I think Beizer has a very good point here, and it just seems wrong to ignore it).

Any comments? I'll check back and see what you all think. Jtowler 18:40, 26 November 2006 (UTC)

Boundary value analysis or Boundary Value Analysis

I'm not sure the recent rename was correct. Is BVA a proper noun? If not WP:TITLE says it should be changed back. --Salix alba (talk) 12:25, 28 January 2007 (UTC)

Of course it's not a proper noun. I've requested a page move 86.152.203.212 13:33, 22 April 2007 (UTC)

Andreas Kaufman, external link

Andreas - you seem to keep adding a link to an external site that contains no information about BVA. I keep removing it. Obviously this is silly. Could you add some info here why the external site you link to is relevant to an article on BVA (rather than to software testing in general). Maybe I am missing something?

Grammatical update needed

The page currently uses "you" a lot, as if it is talking to the reader. This needs to be recast to avoid this. --ΨΦorg (talk) 17:10, 9 June 2008 (UTC)

Test case scenario

A test need to be alaways tested against a BVA so as to determine the effectiveness of the coverage. Might be imp area s gets mis...but alwasys prefr a strong planning in the context of BVa. It requies a wide arae knowledge so as to cover the mximum coverage.

Cost/Benefit Ratio

How does boundary value analysis compare with other testing methods (i.e. fuzz, all-pairs, etc.) in terms of the cost/benefit ratio?

Merger proposal

Merge: I have never heard of Boundary-value analysis ever discussed without having to explain equivalence partitioning. This article is no exception. BVA cannot stand on is own, and EP is just a theory without BVA. --Walter Görlitz (talk) 05:12, 8 May 2009 (UTC)

Don't Merge: Although I principally agree, BVA is not necessarily connected to EP, but EP forms the basis for concrete Testcases, regardless of whether you enhance it with boundary values or not. Furthermore, boundary values are only useful if you have bounds (which is not the case in - say - a dropdown menu with text items that form various equivalence classes... Never connect these two too tight. They are different techniques and this should be reflected here.
