{{short description|Software testing technique in which one establishes test cases based on prior experience}} In software testing, '''error guessing''' is a test method in which test cases used to find bugs in programs are established based on experience in prior testing.<ref name="Homes">Bernard Homès, ''Fundamentals of Software Testing'' (2013), sec. 4.5.3.</ref> The scope of test cases usually rely on the software tester involved, who uses experience and intuition to determine what situations commonly cause software failure, or may cause errors to appear.<ref>R.G. Evans, ''Supercomputational Science'' (2012), p. 39.</ref> Typical errors include divide by zero, null pointers, or invalid parameters.<ref>{{Cite book |last1=Mosley |first1=Daniel J. |url=https://books.google.com/books?id=PEBvfWESIt4C&dq=Error+guessing+software&pg=PA64 |title=Just Enough Software Test Automation |last2=Posey |first2=Bruce A. |date=2002 |publisher=Prentice Hall Professional |isbn=978-0-13-008468-2 |language=en}}</ref>
Error guessing has no explicit rules for testing; test cases can be designed depending on the situation, either drawing from functional documents or when an unexpected/undocumented error is found while testing operations.<ref name="Homes"/>
