A ___MASK54___ ___MASK83___ , in ___MASK74___ engineering , is a set of conditions under which a tester will determine whether an application , ___MASK74___ system or one of its features is working as it was originally established for it to do . The mechanism for determining whether a ___MASK74___ program or system has passed or failed such a ___MASK54___ is known as a " ___MASK54___ oracle ". In some settings , an oracle could be a requirement or use ___MASK83___ , while in others it could be a heuristic . It may take many ___MASK54___ cases to determine that a ___MASK74___ program or system is considered sufficiently scrutinized to be released . Test cases are often referred to as " ___MASK54___ scripts ", particularly when written - when they are usually collected into ___MASK54___ suites . NMock is a library of mock objects to be used in . NET development for ___MASK54___ - driven development . NMock is an open source project that was inspired by the JMock project . The current version as of June 2013 is NMock 3 . 5 . In ___MASK74___ engineering , a ___MASK74___ development methodology ( also known as a system development methodology , ___MASK74___ development life cycle , ___MASK74___ development process , ___MASK74___ process ) is a splitting of ___MASK74___ development work into distinct phases ( or stages ) containing activities with the intent of better planning and management . It is often considered a subset of the systems development life cycle . The methodology may include the pre - definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application . ___MASK54___ - driven development ( TDD ) is a ___MASK74___ development process that relies on the repetition of a very short development cycle : requirements are turned into very specific test cases , then the ___MASK74___ is improved to pass the new tests , only . This is opposed to ___MASK74___ development that allows ___MASK74___ to be added that is not proven to meet requirements .
