JUnit
JUnit is a test automation framework for the Java programming language. JUnit is often used for unit testing, and is one of the xUnit frameworks. JUnit is linked as a JAR at compile-time. The latest version of the framework, JUnit 5, resides under package . Previous versions JUnit 4 and JUnit 3 were under packages and , 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. JUnit Lifecycle Every JUnit test class usually has several test cases. These test cases are subject to the test life cycle. The full JUnit Lifecycle has three major phases: # Setup phase - This phase is where the test infrastructure is prepared. Two levels of setup are available. The first type of setup is class-level setup in which a computationally expensive object, such as a database connection, is created and reused, with mini ...

TestNG
TestNG is a testing framework for the Java programming language created by Cedric_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 co ...

Unit Testing
Unit testing, component or module testing, is a form of software testing by which isolated source code is tested to validate expected behavior. Unit testing describes tests that are run at the unit-level to contrast testing at the Integration testing, integration or System testing, system level. History Unit testing, as a principle for testing separately smaller parts of large software systems, dates back to the early days of software engineering. In June 1956 at US Navy's Symposium on Advanced Programming Methods for Digital Computers, H.D. Benington presented the Semi-Automatic Ground Environment, SAGE project. It featured a specification-based approach where the coding phase was followed by "parameter testing" to validate component subprograms against their specification, followed then by an "assembly testing" for parts put together. In 1964, a similar approach is described for the software of the Project Mercury, Mercury project, where individual units developed by dif ...

Project Object Model
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 (programming language), 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 Software build, 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-in (computing), 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 stor ...

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 previously worked at Facebook. In 2019, Beck joined ...

XUnit
xUnit is a label used for an automated testing software framework that shares significant structure and functionality that is traceable to a common progenitor SUnit. The SUnit framework was ported to Java by Kent Beck and Erich Gamma as JUnit which gained wide popularity. Adaptations to other languages were also popular which led some to claim that the structured, object-oriented style works well with popular languages including Java and C#. The name of an adaptation is often a variation of "SUnit" with the "S" replaced with an abbreviation of the target language name. For example, JUnit for Java and RUnit for R. The term "xUnit" refers to any such adaptation where "x" is a placeholder for the language-specific prefix. The xUnit frameworks are often used for unit testing testing an isolated unit of code but can be used for any level of software testing including integration and system. Architecture An xUnit framework has the following general architecture. Test ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, along with Kent Beck, co-wrote the JUnit software testing framework which helped create Test-Driven Development and . He was the development team lead 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 (previously called Office 365) is a product family of productivity software, collaboration and cloud-based services owned by Micro ...

Apache Ant
Apache Ant is a software tool for automating software build processes for Java applications which originated from the Apache Tomcat project in early 2000 as a replacement for the Make build tool of Unix. It is similar to Make, but is implemented using the Java language and requires the Java platform. Unlike Make, which uses the Makefile format, Ant uses XML to describe the code build process and its dependencies. Released under an Apache License by the Apache Software Foundation, Ant is an open-source project. History Ant ("Another Neat Tool") was conceived by James Duncan Davidson while preparing Sun Microsystems's reference JSP and Servlet engine, later Apache Tomcat, for release as open-source. A proprietary version of Make was used to build it on the Solaris platform, but in the open-source world, there was no way of controlling which platform was used to build Tomcat; so Ant was created as a simple platform-independent tool to build Tomcat from directives in an XM ...

SUnit
SUnit is an automated testing framework written by Kent Beck in 1989; originally intended and often used for unit testing. It supports testing Smalltalk code via test code also written in Smalltalk. SUnit was adapted for Java as JUnit which was notably popular. Subsequently, adaptations were created for many other languages; many also popular.

Java Code Coverage Tools
Java code coverage tools are of two types: first, tools that add statements to the Java (programming language), Java source code and require its recompilation. Second, tools that instrument the bytecode, either before or during execution. The goal is to find out which parts of the code are tested by registering the lines of code coverage, code executed when running a test. JaCoCo JaCoCo is an open-source software, open-source toolkit for measuring and reporting Java (programming language), Java code coverage. JaCoCo is distributed under the terms of the Eclipse Public License. It was developed as a replacement for EMMA, under the umbrella of the EclEmma plug-in for Eclipse. Features JaCoCo offers instructions, line and branch coverage. In contrast to #Clover, Atlassian Clover and #OpenClover, OpenClover, which require instrumenting the source code, JaCoCo can instrument Java bytecode using two different approaches: * like #JCov, JCov on the fly while running the code with a J ...

Apache Ivy
Apache Ivy is a transitive package manager. It is a sub-project of the Apache Ant project, with which Ivy works to resolve project dependencies. An external XML file defines project dependencies and lists the resources necessary to build a project. Ivy then resolves and downloads resources from an artifact repository: either a private repository or one publicly available on the Internet. To some degree, it competes with Apache Maven, which also manages dependencies. However, Maven is a complete build tool, whereas Ivy focuses purely on managing transitive dependencies. History Jayasoft first created Ivy in September, 2004, with Xavier Hanin serving as the principal architect and developer of the project. Jayasoft moved hosting of Ivy (then at version 1.4.1) to Apache Incubator in October 2006. Since then, the project has undergone package renaming to reflect its association with the Apache Software Foundation. Package names prefixes of the form fr.jayasoft.ivy have become org ...
