Antunit is a kind of Ant library in java development that offers the definition and execution of tests within the Ant file. The Ant file belongs to Apache ant, which is a kind of software tool that helps java developers in automating software build processes. The Apache ant is implemented using the Java development language and therefore requires Java developers to possess expertise in Java platform and is specifically meant for creating and developing Java development projects. AntUnit stemmed due to the need to validate pre-conditions in a build type of file and it also offers assertion tags that are ideally utilized to execute tests in combination with simple Java test classes.

Test suites usually function as part of a build process and during the complete process; plenty of test related information is directly embedded into the Ant build files. Once, the whole process is orchestrated, the new Antlib simplifies the setup and the execution. Originally, all the tests that were conducted for Apache Ant projects were coded as individual JUnit test cases. Soon the realization dawned that a major portion of the tests were required to perform redundant and common tasks such as initializing a project, reading a build file and executing a particular target. During this realization the BuildFileTest was developed, which is a kind of a base class that can be used for most of the common task test cases. In order to minimize the repetition work for Java developers, the whole process had to undergo a change over a certain period of time and now Apache AntUnit has become a resourceful solution in Java development that is now used to remove Junit completely and to also offer a set of predefined tasks in order to again use the common kind of checks.

There are a host of other important functions that Antunit performs as part of Java development project, as it can also be used for both integration and functional tests that are outside the scope of Ant tasks. The AntUnit runs the test in a similar manner like JUnit tests and therefore when it calls on a build file, the task automatically begins a new Ant project and searches for targets that start with ‘test’. Hence, at every moment of encountering a target, it will automatically execute the setup for the target name; execute the target and execute the target name tearDown, if there exists one. These are basically some of the functions that the latest version of AntUnit 1.0 Release performs within the Java development projects and gives an opportunity to Java developers to capitalize on its various functionalities.
