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 org.junit.jupiter. [3]
A JUnit test runner that runs JavaScript tests. The goal of the JS Test Runner is to be able to test JavaScript code using an approach that test driven programmers will feel comfortable with; particularly in the context of Continuous Integration. Sinon.js: Compatible: Yes: Yes [237] Standalone test spies, stubs and mocks for JavaScript.
In computer programming, specifically when using the imperative programming paradigm, an assertion is a predicate (a Boolean-valued function over the state space, usually expressed as a logical proposition using the variables of a program) connected to a point in the program, that always should evaluate to true at that point in code execution.
The Iowa State JML tools provide an assertion checking compiler jmlc which converts JML annotations into runtime assertions, a documentation generator jmldoc which produces Javadoc documentation augmented with extra information from JML annotations, and a unit test generator jmlunit which generates JUnit test code from JML annotations.
It supports creating customized assertion matchers ('Hamcrest' is an anagram of 'matchers'), allowing match rules to be defined declaratively. [1] These matchers have uses in unit testing frameworks such as JUnit and jMock. Hamcrest has been included in JUnit 4 since 2007, [2] but was omitted from JUnit 5 in 2017. [3]
import static org.junit.Assert.assertEquals; import org.junit.Test; public class WindowDecoratorTest {@Test public void testWindowDecoratorTest {Window decoratedWindow = new HorizontalScrollBarDecorator (new VerticalScrollBarDecorator (new SimpleWindow ())); // assert that the description indeed includes horizontal + vertical scrollbars ...
Test code is updated as new features are added and failure conditions are discovered (bugs fixed). Commonly, the unit test code is maintained with the project code, integrated in the build process, and run on each build and as part of regression testing. Goals of this continuous integration is to support development and reduce defects. [70] [69]
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.
