Editing Test case (section)

== Informal test cases ==

For applications or systems without formal requirements, test cases can be written based on the accepted normal operation of programs of a similar class. In some schools of testing, test cases are not written at all but the activities and results are reported after the tests have been run.

In [[scenario testing]], hypothetical stories are used to help the tester think through a complex problem or system. These scenarios are usually not written down in any detail. They can be as simple as a diagram for a testing environment or they could be a description written in prose. The ideal scenario test is a story that is motivating, credible, complex, and easy to evaluate. They are usually different from test cases in that test cases are single steps while scenarios cover a number of steps of the key.<ref name="Kaner-Intro">{{cite web | title = An Introduction to Scenario Testing | url = http://www.kaner.com/pdfs/ScenarioIntroVer4.pdf | access-date = 2009-05-07 | publisher = Cem Kaner }}</ref><ref name="Crispin-Agile">{{cite book |last= Crispin |first= Lisa |author2=Gregory, Janet  |title= Agile Testing: A Practical Guide for Testers and Agile Teams |url= https://archive.org/details/agiletestingprac00cris |url-access= limited |publisher= [[Addison-Wesley]] |year= 2009 |isbn= 978-81-317-3068-3 |pages=[https://archive.org/details/agiletestingprac00cris/page/n231 192]–5}}</ref>
