JUnit
JUnit is a unit testing framework for the Java programming language. JUnit has been important in the development of test-driven development, and is one of a family of unit testing frameworks which is collectively known as xUnit that originated with SUnit. JUnit is linked as a JAR at compile-time. The latest version of the framework, JUnit 5, resides under package org.junit.jupiter. Previous versions JUnit 4 and JUnit 3 were under packages org.junit and junit.framework, respectively. A research survey performed in 2013 across 10,000 Java projects hosted on GitHub found that JUnit (in a tie with slf4j-api) was the most commonly included external library. Each library was used by 30.7% of projects. Example of a JUnit test fixture A JUnit test fixture is a Java object. Test methods must be annotated by the @Test annotation. If the situation requires it, it is also possible to define a method to execute before (or after) each (or all) of the test methods with the @BeforeEach (or @ ...

TestNG
TestNG is a testing framework for the Java programming language created by Cédric Beust and inspired by JUnit and NUnit. The design goal of TestNG is to cover a wider range of test categories: unit, functional, end-to-end, integration, etc., with more powerful and easy-to-use functionalities. Features TestNG's main features include: # Annotation support. # Support for data-driven/parameterized testing (with @DataProvider and/or XML configuration). # Support for multiple instances of the same test class (with @Factory) # Flexible execution model. TestNG can be run either by Ant via build.xml (with or without a test suite defined), or by an IDE plugin with visual results. There isn't a TestSuite class, while test suites, groups and tests selected to run are defined and configured by XML files. # Concurrent testing: run tests in arbitrarily big thread pools with various policies available (all methods in their own thread, one thread per test class, etc.), and test whether the cod ...

Apache Maven
Maven is a build automation tool used primarily for Java projects. Maven can also be used to build and manage projects written in C#, Ruby, Scala, and other languages. The Maven project is hosted by the Apache Software Foundation, where it was formerly part of the Jakarta Project. Maven addresses two aspects of building software: how software is built and its dependencies. Unlike earlier tools like Apache Ant, it uses conventions for the build procedure. Only exceptions need to be specified. An XML file describes the software project being built, its dependencies on other external modules and components, the build order, directories, and required plug-ins. It comes with pre-defined targets for performing certain well-defined tasks such as compilation of code and its packaging. Maven dynamically downloads Java libraries and Maven plug-ins from one or more repositories such as the Maven 2 Central Repository, and stores them in a local cache. This local cache of downloaded arti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unit Testing
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. History Before unit testing, capture and replay testing tools were the norm. 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. Description Unit tests are typically automated tests written and run by software developers to ensure that a section of an application (known as the "unit") meets its design and behaves as intended. In procedural programming, a unit could be an entire module, but it is more commonly an individual function or procedure. In object-oriented programming, a unit is often an entire interface, such as a class, or an individual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kent Beck
Kent Beck (born 1961) is an American software engineer and the creator of extreme programming, a software development methodology that eschews rigid formal specification for a collaborative and iterative design process. Beck was one of the 17 original signatories of the Agile Manifesto,"Extreme Programming", ''Computerworld'' (online), 2005, webpageComputerworld-appdev-92 the founding document for agile software development. Extreme and Agile methods are closely associated with Test-Driven Development (TDD), of which Beck is perhaps the leading proponent. Beck pioneered software design patterns, as well as the commercial application of Smalltalk. He wrote the SUnit unit testing framework for Smalltalk, which spawned the xUnit series of frameworks, notably JUnit for Java, which Beck wrote with Erich Gamma. Beck popularized CRC cards with Ward Cunningham, the inventor of the wiki. He lives in San Francisco, California and worked at social media company Facebook. In 2019, Beck ...

Erich Gamma
Erich Gamma is a Swiss computer scientist and one of the four co-authors (referred to as "Gang of Four") of the software engineering textbook, '' Design Patterns: Elements of Reusable Object-Oriented Software''. Gamma is an expert in the Eclipse Java development editor, and with Kent Beck he co-wrote the JUnit software testing framework which helped create Test-Driven Development and influenced the whole software industry. He also led the design of the Eclipse platform's Java Development ToolsJDT, and worked on the IBM RationaJazz project In 2011 he joined the Microsoft Visual Studio team and leads a development lab in Zürich, Switzerland that has developed the "Monaco" suite of components for browser-based development, found in products such as Azure DevOps Services (formerly Visual Studio Team Services and Visual Studio Online), Visual Studio Code, Azure Mobile Services, Azure Web Sites, and the Office 365 Microsoft 365 is a product family of productivity software, coll ...

XUnit
xUnit is the collective name for several unit testing frameworks that derive their structure and functionality from Smalltalk's SUnit. ''SUnit'', designed by Kent Beck in 1998, was written in a highly structured object-oriented style, which lent easily to contemporary languages such as Java and C#. Following its introduction in Smalltalk the framework was ported to Java by Kent Beck and Erich Gamma and gained wide popularity, eventually gaining ground in the majority of programming languages in current use. The names of many of these frameworks are a variation on "SUnit", usually replacing the "S" with the first letter (or letters) in the name of their intended language ("JUnit" for Java, "RUnit" for R etc.). These frameworks and their common architecture are collectively known as "xUnit". xUnit architecture All xUnit frameworks share the following basic component architecture, with some varied implementation details. Test runner A test runner is an executable program that r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EvoSuite
EvoSuite is a tool that automatically generates unit tests for Java software. EvoSuite uses an evolutionary algorithm to generate JUnit tests. EvoSuite can be run from the command line, and it also has plugins to integrate it in Maven, IntelliJ and Eclipse. EvoSuite has been used on more than a hundred open-source software and several industrial systems, finding thousands of potential bugs. History EvoSuite was originally created in 2010 as output of a research project by Dr. Gordon Fraser and Dr. Andrea Arcuri. EvoSuite is currently released under LGPL license, and its source code is hosted on GitHub. In academia, EvoSuite is often referred as one of the main reference tools for search-based software testing. Other usages As EvoSuite is released as open-source (and so freely available to download and modify), it has been used as a reference tool for search-based software testing in a number of independent studies, like: * Comparison with other tools like Pex, CATG, jPET and SPF ...

Mockito
Mockito is an open source testing framework for Java released under the MIT License. The framework allows the creation of test double objects (mock objects) in automated unit tests for the purpose of test-driven development (TDD) or behavior-driven development (BDD). The framework's name and logo are a play on mojitos, a type of drink. Features Mockito allows developers to verify the behavior of the system under test (SUT) without establishing expectations beforehand. One of the criticisms of mock objects is that there is a tight coupling of the test code to the system under test. Mockito attempts to eliminate the expect-run-verify pattern by removing the specification of expectations. Mockito also provides some annotations for reducing boilerplate code. Origins Mockito began by expanding on the syntax and functionality of EasyMock. Example Consider this decoupled Hello world program; we may unit test some of its parts, using mock objects for other parts. package org.ex ...

SLF4J
Simple Logging Facade for Java (SLF4J) provides a Java logging API by means of a simple facade pattern. The underlying logging backend is determined at runtime by adding the desired binding to the classpath and may be the standard Sun Java logging package java.util.logging, Log4j, Reload4j, Logback or tinylog. The separation of the client API from the logging backend reduces the coupling between an application and any particular logging framework. This can make it easier to integrate with existing or third-party code or to deliver code into other projects that have already made a choice of logging backend. SLF4J was created by Ceki Gülcü as a more reliable alternative to Jakarta Commons Logging framework. Research in 2013 on 10,000 GitHub projects found that the most popular Java library is SLF4J, along with JUnit, with 30.7% of projects using it. In January 2021, it was ranked as the second most popular project according to mvnrepository. Similarities and differences with l ...

Java (; id, Jawa, ; jv, ꦗꦮ; su, ) is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea to the north. With a population of 151.6 million people, Java is the world's most populous island, home to approximately 56% of the Indonesian population. Indonesia's capital city, Jakarta, is on Java's northwestern coast. Many of the best known events in Indonesian history took place on Java. It was the centre of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally. Four of Indonesia's eight UNESCO world heritage sites are located in Java: Ujung Kulon National Park, Borobudur Temple, Prambanan Temple, and Sangiran Early Man Site.
