QUnit
QUnit is a JavaScript framework for unit testing. Originally developed for testing jQuery, jQuery UI and jQuery Mobile, it is a generic framework for testing any JavaScript code. It supports client-side environments in web browsers, and server-side (e.g. Node.js). QUnit's assertion methods follow the CommonJS unit testing specification, which itself was influenced to some degree by QUnit. History John Resig originally developed QUnit as part of jQuery. In 2008 it was extracted from the jQuery unit test code to form its project and became known as "QUnit". This allowed others to start using it for writing their unit tests. While the initial version of QUnit used jQuery for interaction with the Document Object Model, DOM, a Rewrite (programming), rewrite in 2009 made QUnit completely standalone. A 2017 analysis of npm and GitHub code repositories showed QUnit was the third most prevalent framework, with half as much usage as the most popular framework, Mocha (JavaScript frame ...

List Of Unit Testing Frameworks
This is a list of notable test automation frameworks commonly used for unit testing. Such frameworks are not limited to unit-level testing; can be used for integration and system level testing. Frameworks are grouped below. For unit testing, a framework must be the same language as the source code under test, and therefore, grouping frameworks by language is valuable. But some groupings transcend language. For example, .NET groups frameworks that work for any language supported for .NET, and HTTP groups frameworks that test an HTTP server regardless of the implementation language on the server. Columns The columns in the tables below are described here. * Name: Name of the framework * xUnit: Whether classified as xUnit * TAP: Whether can emit Test Anything Protocol (TAP) output * Generators: Whether supports data generators generating test input data and running a test with the generated data * Fixtures: Whether supports test local fixtures associating a test environment ...

Jasmine (JavaScript Framework)
Jasmine is an open-source testing framework for JavaScript. It aims to run on any JavaScript-enabled platform, to not intrude on the application nor the IDE, and to have easy-to-read syntax. It is heavily influenced by other unit testing frameworks, such as ScrewUnit, JSSpec, JSpec, and RSpec. History The developers at Pivotal Labs for Jasmine previously developed a similar unit testing framework called JsUnit before active development of Jasmine. Features * Supports asynchronous testing. * Makes use of 'spies' for implementing test doubles. * Supports testing of front-end code through a front-end extension of Jasmine called Jasmine-jQuery. Usage Jasmine aims to be easy to read. A simple hello world test looks like the code below, where describe() describes a suite of tests and it() is an individual test specification. The name "it()" follows the idea of behavior-driven development and serves as the first word in the test name, which should be a complete sentence. Usag ...

Mocha (JavaScript Framework)
Mocha is a JavaScript test framework for Node.js programs, featuring browser support, asynchronous testing, test coverage reports, and use of any assertion library. Assertion libraries Mocha can be used with most JavaScript assertion libraries, including: * should.js * express.js * chai * better-assert * unexpected Usage and examples $ npm install -g mocha $ mkdir test $ $EDITOR test/test.js # or open with your favorite editor var assert = require("assert") describe('Foo', function()) $ mocha . 1 test complete (1ms) For asynchronous testing, invoke the callback, and Mocha will wait for completion. describe('Foo', function()) See also * Jasmine * List of unit testing frameworks * npm * QUnit * JavaScript framework * JavaScript library A JavaScript library is a library of pre-written JavaScript code that allows for easier development of JavaScript-based applications, especially for AJAX and other web-centric technologies.

CommonJS
CommonJS is a project to standardize the module ecosystem for JavaScript outside of web browsers (e.g. on web servers or native desktop applications). CommonJS's specification of how modules should work is widely used today for server-side JavaScript with Node.js. It is also used for browser-side JavaScript, but that code must be packaged with a transpiler since browsers don't support CommonJS. The other major module specification in use is the ECMAScript (ES) modules specification (ES6 modules aka ES2015 modules). CommonJS can be recognized by the use of the require() function and module.exports, while ES modules use import and export statements for similar (though not identical) functionality. History The project was started by Mozilla engineer Kevin Dangoor in January, 2009 and initially named ServerJS. In August 2009, the project was renamed ''CommonJS'' to show the broader applicability of the APIs. Specifications are created and approved in an open process. A specifi ...

Qubit
In quantum computing, a qubit () or quantum bit is a basic unit of quantum information—the quantum version of the classic binary bit physically realized with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics. Examples include the spin of the electron in which the two levels can be taken as spin up and spin down; or the polarization of a single photon in which the two spin states (left-handed and the right-handed circular polarization) can also be measured as horizontal and vertical linear polarization. In a classical system, a bit would have to be in one state or the other. However, quantum mechanics allows the qubit to be in a coherent superposition of multiple states simultaneously, a property that is fundamental to quantum mechanics and quantum computing. Etymology The coining of the term ''qubit'' is attributed to Benjamin Schumacher. In the acknow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

JavaScript Programming Tools
JavaScript (), often abbreviated as JS, is a programming language and core technology of the World Wide Web, alongside HTML and CSS. Ninety-nine percent of websites use JavaScript on the Client (computing), client side for Web page, webpage behavior. Web browsers have a dedicated JavaScript engine that executes the client Source code, code. These engines are also utilized in some Server (computing), servers and a variety of Application software, apps. The most popular runtime system for non-browser usage is Node.js. JavaScript is a High-level programming language, high-level, often Just-in-time compilation, just-in-time–compiled language that conforms to the ECMAScript standard. It has dynamic typing, Prototype-based programming, prototype-based object-oriented programming, object-orientation, and first-class functions. It is Programming paradigm, multi-paradigm, supporting Event-driven programming, event-driven, functional programming, functional, and imperative programming ...

JavaScript Library
A JavaScript library is a library of pre-written JavaScript code that allows for easier development of JavaScript-based applications, especially for AJAX and other web-centric technologies. They can be included in a website by embedding it directly in the HTML via a script tag. Libraries With the expanded demands for JavaScript, an easier means for programmers to develop such dynamic interfaces was needed. Thus, JavaScript libraries and JavaScript widget libraries were developed, allowing for developers to concentrate more upon more distinctive applications of Ajax. This has led to other companies and groups, such as Microsoft and Yahoo! developing their own JavaScript-based user interface libraries, which find their way into the web applications developed by these companies. Some JavaScript libraries allow for easier integration of JavaScript with other web development technologies, such as CSS, PHP, Ruby, and Java, while others provide utilities, often in the form of JavaScript ...

JavaScript Framework
A web framework (WF) or web application framework (WAF) is a software framework that is designed to support the development of web applications including web services, web resources, and web APIs. Web frameworks provide a standard way to build and deploy web applications on the World Wide Web. Web frameworks aim to automate the overhead associated with common activities performed in web development. For example, many web frameworks provide libraries for database access, templating frameworks, and session management, and they often promote code reuse. Although they often target development of dynamic web sites, they are also applicable to static websites. History As the design of the World Wide Web was not inherently dynamic, early hypertext consisted of hand-coded HTML text files that were published on web servers. Any modifications to published pages needed to be performed by the pages' author. In 1993, the Common Gateway Interface (CGI) standard was introduced for interfa ...

JavaScript Syntax
The syntax of JavaScript is the set of rules that define a correctly structured JavaScript program. The examples below make use of the log function of the console object present in most browsers for standard text output. The JavaScript standard library lacks an official standard text output function (with the exception of document.write). Given that JavaScript is mainly used for client-side scripting within modern web browsers, and that almost all Web browsers provide the alert function, alert can also be used, but is not commonly used. Origins Brendan Eich summarized the ancestry of the syntax in the first paragraph of the JavaScript 1.1 specification as follows: Basics Case sensitivity JavaScript is case sensitive. It is common to start the name of a constructor with a capitalized letter, and the name of a function or variable with a lower-case letter. Example: var a = 5; console.log(a); // 5 console.log(A); // throws a ReferenceError: A is not defined Whitesp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boolean Data Type
In computer science, the Boolean (sometimes shortened to Bool) is a data type that has one of two possible values (usually denoted ''true'' and ''false'') which is intended to represent the two truth values of logic and Boolean algebra. It is named after George Boole, who first defined an algebraic system of logic in the mid 19th century. The Boolean data type is primarily associated with conditional statements, which allow different actions by changing control flow depending on whether a programmer-specified Boolean ''condition'' evaluates to true or false. It is a special case of a more general ''logical data type—''logic does not always need to be Boolean (see probabilistic logic). Generalities In programming languages with a built-in Boolean data type, such as Pascal, C, Python or Java, the comparison operators such as > and ≠ are usually defined to return a Boolean value. Conditional and iterative commands may be defined to test Boolean-valued expressions. L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
