Automate Ant: Ædificemus vobiscum,
Overview:
Ant tool constructum in hoc documento de nobis de nobis, et per hoc quod potest automate constructum mechanism fundatur applications pro Java. O tempora hodierna progressione facta est pars integralis Java. Maxime ut mos est scriptor automated pars constructum source codice liberati. Cuius ratio est, ut aliquis simplicem ant parum provisum est posse generare Scripting deployable applicando singula nesciens binarii.
Introductio:
Apache ant is a generic build tool. Ant: nomen enim pro abbreviated 'Alius tersus Tool,. Hoc simile est instrumentum fac utilitas impletur nisi in Unix usura Java. Est enim prius in aedificationem binaries Java in in aciemque genitus, et binarii codice ex quo est, quod est in Application Server praedefinitum. It can also be used to generate javadocs for a code base and to execute the unit test suite for the whole codebase. Ant in collaboration with JUNIT helps developer to follow the test driven development approach.
Ant requires Java compiler to be installed having the environment variable JAVA_HOME set with its adequate value. Ant uses an XML file to define the build procedure. Et hoc est nomen, default lima build.xml. Quidam developers uti etiam a lima quod proprietates ad determinare de substantia build.properties e.g. the build version number and other environmental parameters which are required to change from time to time based on the need.
Installation:
Fedora: On RHEL, ANT can be installed using the command – yum install ant or it can be installed using the rpm – i command. In this case you should download the ant package first.
debian: On Ubuntu, ANT can be installed using the command – apt-get install ant.
Windows: On windows environment we need to download the ant_<VERSION_NO>.zip file. This zip bundle should be extracted in a folder. This folder should be defined as an environment variable ANT_HOME.
A sample build.xml file is shown as under:
LISTING 1: Sample build.xml file
[Code]
<?xml version=”1.0″?>
<project name=”Ant-Test” default=”Summa” basedir=”.”>
<!– Sets variables which can later be used. –>
<!– The value of a property is accessed via ${} –>
<property name=”src.dir” location=”src” />
<property name=”build.dir” location=”bin” />
<property name=”dist.dir” location=”dist” />
<property name=”docs.dir” location=”docs” />
<!– Deletes the existing build, docs and dist directory–>
<target name=”clean”>
<delete dir=”${build.dir}” />
<delete dir=”${docs.dir}” />
<delete dir=”${dist.dir}” />
</target>
<!– Creates the build, docs and dist directory–>
<target name=”makedir”>
<mkdir dir=”${build.dir}” />
<mkdir dir=”${docs.dir}” />
<mkdir dir=”${dist.dir}” />
</target>
<!– Compiles the java code (including the usage of library for JUnit –>
<target name=”compile” depends=”clean, makedir”>
<javac srcdir=”${src.dir}” destdir=”${build.dir}”>
</javac>
</target>
<!– Creates Javadoc –>
<target name=”docs” depends=”compile”>
<javadoc packagenames=”src” sourcepath=”${src.dir}” destdir=”${docs.dir}”>
<!– Define which files / directory should get included, we include all –>
<fileset dir=”${src.dir}”>
<include name=”**” />
</fileset>
</javadoc>
</target>
<!–Creates the deployable jar file –>
<target name=”jar” depends=”compile”>
<jar destfile=”${dist.dir}\in.kolkalta.build.test.ant.jar” basedir=”${build.dir}”>
<manifest>
<attribute name=”Main-Class” value=”test.Main” />
</manifest>
</jar>
</target>
<target name=”Summa” depends=”compile, jar, docs”>

ANT per Automation:
Ant praebet a magna auxilium ad Java tincidunt. Java elit fere similis habere scriptum test, quod partum cura unitas binario distributione currentium lima quod can exsisto servo orietur applicatio. Ant quoque suggero run in viis quae sunt facere scriptor automated probat in unum codicem basim. Thus, Maecenas eget auxilio, qui per ipsum accessum ad pulsus test,. As we know in test driven development methodology JUNIT is a compulsion, Added semper commodo est scriptor automated currit si habemus in omnibus casibus ire junit amet. Si non solum hoc quod scriptum est continuus adhiberi potest integrationem tooled e.g. Hudson. Our following sample code illustrates how to use ANT with JUNIT.
LISTING 2: A Sample java file
[Code]
package com.home.junit;
publicas classis SampleAdd {
publicas int addunt(int x, int y) {
return x + y;
}
}
[/Code]
LISTING 3: The corresponding JUNIT file
[Code]
package com.home.junit;
import org.junit.After;
import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
public class SampleAddTest {
private SampleAdd sampleClass;
@Before
public void setUp() {
sampleClass = new SampleAdd();
}
@Test
public void testAdd() {
Assert.assertEquals(5, sampleClass.add(3, 2));
}
@After
public void settleDown() {
sampleClass = null;
}
}
[/Code]
LISTING 4: The ANT script to compile and run the JUNIT test
[Code]
<?xml version=”1.0″?>
<project name=”JUNIT” default=”Summa” basedir=”..”>
<!– Sets variables which can later be used. –>
<!– The value of a property is accessed via ${} –>
<property name=”src.dir” location=”src” />
<property name=”test.dir” location=”tests” />
<property name=”build.dir” location=”bin” />
<property name=”build.test.dir” location=”bin/tests” />
<!– Variables used for JUnit testin –>
<property name=”test.report.dir” location=”testreport” />
<!– Define the classpath which includes the junit.jar and the classes after compiling–>
<path id=”junit.class.path”>
<pathelement location=”lib/junit-4.11.jar” />
<pathelement location=”lib/hamcrest-core-1.3.jar” />
<pathelement location=”${build.dir}” />
</path>
<!– Deletes the existing build, docs and dist directory–>
<target name=”clean”>
<delete dir=”${build.dir}” />
<delete dir=”${test.report.dir}” />
</target>
<!– Creates the build, docs and dist directory–>
<target name=”makedir”>
<mkdir dir=”${build.dir}” />
<mkdir dir=”${build.test.dir}” />
<mkdir dir=”${test.report.dir}” />
</target>
<!– Compiles the java code (including the usage of library for JUnit –>
<target name=”compile” depends=”clean, makedir”>
<javac srcdir=”${src.dir}” destdir=”${build.dir}”>
<classpath refid=”junit.class.path” />
</javac>
<javac srcdir=”${test.dir}” destdir=”${build.test.dir}”>
<classpath refid=”junit.class.path” />
</javac>
</target>
<!– Run the JUnit Tests –>
<!– Output is XML, could also be plain–>
<target name=”junit” depends=”compile”>
<junit printsummary=”on” fork=”verum” haltonfailure=”yes”>
<classpath refid=”junit.class.path” />
<classpath>
<pathelement location=”${build.test.dir}”/>
</classpath>
<formatter type=”xml” />
<batchtest todir=”${test.report.dir}”>
<fileset dir=”${test.dir}”>
<include name=”**/*Test*.java” />
</fileset>
</batchtest>
</junit>
</target>
<target name=”Summa” depends=”compile, junit”>
<description>Main target</description>
</target>
</project>

When we run this script, primo basi code congero congero, et tunc currit junit probat in codicem et ultimum a generat Test Report. The test report can be generated in any format. For convenience we have generated this in XML format.

Conclusio:
- Apache Ant Java utilitatem quae ex his developers Java et per ipsum
- To generate the binaries from the source code
- To generate javadocs for the source code
- To run JUNIT test cases on a code base
- ANT in collaboration with JUNIT, helps the java developers to follow the Test Driven Development methodology
