QUnit is a JavaScript unit testing framework. 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).

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 DOM, a rewrite in 2009 made QUnit completely standalone.

Usage and examples

QUnit.module(string) - Defines a module, a grouping of one or more tests.
QUnit.test(string, function) - Defines a test.

QUnit uses a set of assertion method to provide semantic meaning in unit tests:^[2]

assert.ok(boolean, string) - Asserts that the provided value casts to boolean true.
assert.equal(value1, value2, message) - Compares two values, using the double-equal operator.
assert.deepEqual(value1, value2, message) - Compares two values based on their content, not just their identity.
assert.strictEqual(value1, value2, message) - Strictly compares two values, using the triple-equal operator.

A basic example would be as follows:^[3]

QUnit.test('a basic test example',function(assert){varobj={};assert.ok(true,'Boolean true');// passesassert.ok(1,'Number one');// passesassert.ok(false,'Boolean false');// failsobj.start='Hello';obj.end='Ciao';assert.equal(obj.start,'Hello','Opening greet');// passesassert.equal(obj.end,'Goodbye','Closing greet');// fails});

In object-oriented (OO) and functional programming, an immutable object is an object whose state cannot be modified after it is created. This is in contrast to a mutable object, which can be modified after it is created. In some cases, an object is considered immutable even if some internally used attributes change, but the object's state appears unchanging from an external point of view. For example, an object that uses memoization to cache the results of expensive computations could still be considered an immutable object.

In computer programming, unit testing is a software testing method by which individual units of source code—sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures—are tested to determine whether they are fit for use. It is a standard step in development and implementation approaches such as Agile.

In computer science, reflective programming or reflection is the ability of a process to examine, introspect, and modify its own structure and behavior.

NUnit is an open-source unit testing framework for the .NET Framework and Mono. It serves the same purpose as JUnit does in the Java world, and is one of many programs in the xUnit family.

Apache Groovy is a Java-syntax-compatible object-oriented programming language for the Java platform. It is both a static and dynamic language with features similar to those of Python, Ruby, and Smalltalk. It can be used as both a programming language and a scripting language for the Java Platform, is compiled to Java virtual machine (JVM) bytecode, and interoperates seamlessly with other Java code and libraries. Groovy uses a curly-bracket syntax similar to Java's. Groovy supports closures, multiline strings, and expressions embedded in strings. Much of Groovy's power lies in its AST transformations, triggered through annotations.

ActionScript is an object-oriented programming language originally developed by Macromedia Inc.. It is influenced by HyperTalk, the scripting language for HyperCard. It is now an implementation of ECMAScript, though it originally arose as a sibling, both being influenced by HyperTalk. ActionScript code is usually converted to byte-code format by a compiler.

A query string is a part of a uniform resource locator (URL) that assigns values to specified parameters. A query string commonly includes fields added to a base URL by a Web browser or other client application, for example as part of an HTML document, choosing the appearance of a page, or jumping to positions in multimedia content.

<span class="mw-page-title-main">Dependency injection</span> Software programming technique

In software engineering, dependency injection is a programming technique in which an object or function receives other objects or functions that it requires, as opposed to creating them internally. Dependency injection aims to separate the concerns of constructing objects and using them, leading to loosely coupled programs. The pattern ensures that an object or function which wants to use a given service should not have to know how to construct those services. Instead, the receiving 'client' is provided with its dependencies by external code, which it is not aware of. Dependency injection makes implicit dependencies explicit and helps solve the following problems:

<span class="mw-page-title-main">Null (SQL)</span> Marker used in SQL databases to indicate a value does not exist

In SQL, null or NULL is a special marker used to indicate that a data value does not exist in the database. Introduced by the creator of the relational database model, E. F. Codd, SQL null serves to fulfil the requirement that all true relational database management systems (RDBMS) support a representation of "missing information and inapplicable information". Codd also introduced the use of the lowercase Greek omega (ω) symbol to represent null in database theory. In SQL, NULL is a reserved word used to identify this marker.

The syntax of JavaScript is the set of rules that define a correctly structured JavaScript program.

The conditional operator is supported in many programming languages. This term usually refers to ?: as in C, C++, C#, and JavaScript. However, in Java, this term can also refer to && and ||.

jQuery is a JavaScript library designed to simplify HTML DOM tree traversal and manipulation, as well as event handling, CSS animations, and Ajax. It is free, open-source software using the permissive MIT License. As of August 2022, jQuery is used by 77% of the 10 million most popular websites. Web analysis indicates that it is the most widely deployed JavaScript library by a large margin, having at least 3 to 4 times more usage than any other JavaScript library.

Hamcrest is a framework that assists writing software tests in the Java programming language. It supports creating customized assertion matchers, allowing match rules to be defined declaratively. These matchers have uses in unit testing frameworks such as JUnit and jMock. Hamcrest has been included in JUnit 4 since 2012, but was omitted from JUnit 5 in 2017.

Ateji PX is an object-oriented programming language extension for Java. It is intended to facilliate parallel computing on multi-core processors, GPU, Grid and Cloud.

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.

<span class="mw-page-title-main">JsPHP</span> Cross-browser JavaScript library

JsPHP is a cross-browser JavaScript library designed to make the PHP application programming interface (API) available in JavaScript environments. It was started by Kevin van Zonneveld as php.js and released as an open-source project in 2008. In late 2011 John Elliot forked the php.js project to JsPHP and released a web-based collaborative integrated development environment (IDE) at www.jsphp.com in an effort to rejuvenate and breathe new life into the project, and as an excuse to develop a content management system (CMS) with features for software developers, such as unit testing and benchmarking.

Mocha is a JavaScript test framework for Node.js programs, featuring browser support, asynchronous testing, test coverage reports, and use of any assertion library.

Nim is a general-purpose, multi-paradigm, statically typed, compiled high-level systems programming language, designed and developed by a team around Andreas Rumpf. Nim is designed to be "efficient, expressive, and elegant", supporting metaprogramming, functional, message passing, procedural, and object-oriented programming styles by providing several features such as compile time code generation, algebraic data types, a foreign function interface (FFI) with C, C++, Objective-C, and JavaScript, and supporting compiling to those same languages as intermediate representations.
