Unit testing
Unit testing, a.k.a. component or module testing, is a form of software testing by which isolated source code is tested to validate expected behavior.
Unit testing describes tests that are run at the unit-level to contrast testing at the integration or system level.
Unit testing, as a principle for testing separately smaller parts of large software systems, dates back to the early days of software engineering. In June 1956 at US Navy's Symposium on Advanced Programming Methods for Digital Computers, H.D. Benington presented the SAGE project. It featured a specification-based approach where the coding phase was followed by "parameter testing" to validate component subprograms against their specification, followed then by an "assembly testing" for parts put together.
In 1964, a similar approach is described for the software of the Mercury project, where individual units developed by different programmes underwent "unit tests" before being integrated together. In 1969, testing methodologies appear more structured, with unit tests, component tests and integration tests collectively validating individual parts written separately and their progressive assembly into larger blocks. Some public standards adopted in the late 1960s, such as MIL-STD-483 and MIL-STD-490, contributed further to a wide acceptance of unit testing in large projects.
Unit testing was in those times interactive or automated, using either coded tests or capture and replay testing tools. In 1989, Kent Beck described a testing framework for Smalltalk (later called SUnit) in "Simple Smalltalk Testing: With Patterns". In 1997, Kent Beck and Erich Gamma developed and released JUnit, a unit test framework that became popular with Java developers. Google embraced automated testing around 2005–2006.
A unit is defined as a single behaviour exhibited by the system under test (SUT), usually corresponding to a requirement[definition needed]. While a unit may correspond to a single function or module (in procedural programming) or a single method or class (in object-oriented programming), functions/methods and modules/classes do not necessarily correspond to units. From the system requirements perspective only the perimeter of the system is relevant, thus only entry points to externally visible system behaviours define units.[clarification needed]
Unit tests can be performed manually or via automated test execution. Automated tests include benefits such as: running tests often, running tests without staffing cost, and consistent and repeatable testing.
Testing is often performed by the programmer who writes and modifies the code under test. Unit testing may be viewed as part of the process of writing code.
