System integration testing (SIT) involves the overall testing of a complete system of many subsystem components or elements. The system under test may be composed of electromechanical or computer hardware, or software , or hardware with embedded software , or hardware/software with human-in-the-loop testing.
Unit is defined as a single behaviour exhibited by the system under test (SUT), usually corresponding to a requirement [definition needed].While it may imply that it is a function or a module (in procedural programming) or a method or a class (in object-oriented programming) it does not mean functions/methods, modules or classes always correspond to units.
Although a conference room pilot shares some features of user acceptance testing (UAT), it should not be considered a testing process – it validates that a design or solution is fit for purpose at a higher level than functional testing. Shared features of CRP and UAT include: End-to-end business processes are used as a "business input" for ...
A device under test (DUT), also known as equipment under test (EUT) and unit under test (UUT), is a manufactured product undergoing testing, either at first manufacture or later during its life cycle as part of ongoing functional testing and calibration checks. This can include a test after repair to establish that the product is performing in ...
[1] [2] When used to determine if a computer program should be subjected to further, more fine-grained testing, a smoke test may be called a pretest [5] or an intake test. [1] Alternatively, it is a set of tests run on each new build of a product to verify that the build is testable before the build is released into the hands of the test team. [6]

One agile practice, test-driven software development (TDD), is a way of unit testing such that unit-level testing is performed while writing the product code. [69] Test code is updated as new features are added and failure conditions are discovered (bugs fixed).
Acceptance testing can mean one of two things: A smoke test is used as an acceptance test prior to introducing a new build to the main testing process, i.e., before integration or regression. Acceptance testing performed by the customer, often in their lab environment on their own hardware, is known as user acceptance testing (UAT). Acceptance ...
