The term closure is often used as a synonym for anonymous function, though strictly, an anonymous function is a function literal without a name, while a closure is an instance of a function, a value, whose non-local variables have been bound either to values or to storage locations (depending on the language; see the lexical environment section below).
Google Closure Tools [3] was a set of tools built with the goal of helping developers optimize rich web applications with JavaScript. It was developed by Google for use in their web applications such as Gmail, Google Docs and Google Maps. [4] As of Aug 1, 2024 the Closure Library has been sunset, for not "meeting the needs of modern JavaScript ...

API testing is a type of software testing that involves testing application programming interfaces (APIs) directly and as part of integration testing to determine if they meet expectations for functionality, reliability, performance, and security. [1] Since APIs lack a GUI, API testing is performed at the message layer. [2]
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.
With TPT, each test case can specifically react to the system's behaviour [8] during the testing process in real time – for instance to react on the system exactly when a certain system-state occurs or a sensor signal exceeds a certain threshold. If, for example, a sensor failure for an engine controller is to be simulated when the engine ...
Test method: There are two main ways of testing mobile applications: testing on real devices or testing on emulators. [6] Emulators often miss issues that can only be caught by testing on real devices, but because of the multitude of different devices in the market, real devices can be expensive to purchase and time-consuming to use for testing.
In software testing, a test harness is a collection of stubs and drivers configured to assist with the testing of an application or component. [1] [2] It acts as imitation infrastructure for test environments or containers where the full infrastructure is either not available or not desired. Test harnesses allow for the automation of tests ...
