[edit] Merge Edge case and Boundary case?

After reading these two articles they seem to be referring to identical concepts, but since I am not an engineer, I am hesitant to be bold and merge them myself. Is there some technical difference that I'm not getting? Or are they really identical?--Aervanath 15:40, 31 January 2007 (UTC)

From reading the article text I don't think they are identical concepts, although they are related to some extent. "Edge case" refers to a problem - in any system - that occurs at a maximum or minimum input parameter. "Boundary case" refers to the behaviour of a software system at, or just beyond, a maximum or minimum input parameter.

It follows that when testing a software system, you need to work out the boundary cases in order to determine if there are any edge cases.

The term "boundary case" apparently is not used outside of the software engineering field, whereas "edge case" is used across all engineering disciplines. All of the above assumes that these articles are accurate, which of course they may not be. 217.34.39.123 11:30, 2 February 2007 (UTC)

I concur that they are related but not identical. "Edge case" is broader term than "Boundary case" and they can be defined, explained and applied in different ways. ChrisHardie 02:15, 15 April 2007 (UTC)
