Editing Cross-platform software (section)

==== Testing <span class="anchor" id="Testing strategies"></span>====
Cross-platform applications need much more [[integration testing]]. Some web browsers prohibit installation of different versions on the same machine. There are several approaches used to target multiple platforms, but all of them result in software that requires substantial manual effort for testing and maintenance.<ref>{{Cite book|last=Choudhary|first=S.R.|title=Companion Proceedings of the 36th International Conference on Software Engineering |chapter=Cross-platform testing and maintenance of web and mobile applications |date=2014|pages=642–645|doi=10.1145/2591062.2591097|isbn=9781450327688|s2cid=1903037|hdl=1853/53588|hdl-access=free |url=https://repository.gatech.edu/server/api/core/bitstreams/c283fd1a-551d-4b0e-a7da-7add80df2328/content }}</ref> Techniques such as [[full virtualization]] are sometimes used as a workaround for this problem.

Tools such as the Page Object Model allow cross-platform tests to be scripted so that one test case covers multiple versions of an app. If different versions have similar user interfaces, all can be tested with one test case.
