Line 1:
'''System under test''' ('''SUT''') refers to a [[software system|system]] that is being tested for correct operation. According to [[ISTQB]] it is the test object.<ref>http://wwwglossary.astqbistqb.org/glossary/search/suttest%20object</ref><ref>https://robots.thoughtbot.com/don-t-stub-the-system-under-test</ref><ref>http://www.itwissen.info/definition/lexikon/SUT-system-under-test.html</ref> The term is used mostly in [[software testing]].
 
A special case of a software system is an [[application software|application]] which, when tested, is called an application under test.
 
The term SUT means also a stage of maturity of the software, because a system test is the successor of integration test in the testing cycle.
