Automatiseerida ehitada Ant
Ülevaade:
Selles dokumendis me arutleda ehitada vahend sipelgate ja kasutavad seda, kuidas me saame automatiseerida ehitada mehhanismi Java rakendusi. Tänapäeva ajastu ant on saanud lahutamatu osa java areng. Enamik kliente tahaksid olla automatiseeritud build osana tarnitud lähtekoodi. Selle põhjuseks on lihtsus, mida ant nii et igaüks, kellel on vähe skriptimine teadmisi saab genereerida positsioonidele binaarne tundmata kohaldamise üksikasjalikult.
Sissejuhatus:
Apache ant is a generic build tool. Nimi ANT seisab lühendatud "Teine Neat Tool". See näitaja on sarnane "Tee" kasuliku UNIX kuid on teostatud kasutades Java. Seda kasutatakse peamiselt hoone Binaarfailidesse Java põhineb lähtekoodi ja rakendades loodud binaarne rakendus serveri, mis on eelnevalt kindlaks määratud. 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 nõuab Java kompilaatori paigaldada olles keskkonnamuutuja JAVA_HOME seada oma piisavat väärtust. Ant kasutab XML-faili määratleda ehitada korras. Vaikimisi nimi see fail on build.xml. Mõned arendajad kasutada ka omadused faili nimelt build.properties määratleda mõned omadused, nt. 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=”põhiline” 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>
<!– Loob ehitada, 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>
<!–Loob positsioonidele jar faili –>

Automation kasutades ANT:
Ant annab suureks abiks Java Developers. Peaaegu iga java arendaja tahaksid olla skript, mis suudan töötab üksuse test ja luua binaarfailina faili, mida saab kasutusele võtta rakenduse serverit. Ant pakub ka võimalust käivitada automatiseeritud skripte, mida kasutatakse sooritada ühiku testid koodi baasi. Thus, see annab abi arendajatele, kes kasutavad test juhitud arengu lähenemisviisi. As we know in test driven development methodology JUNIT is a compulsion, see on alati eelis, kui meil on automatiseeritud skripti kõik rongid test juhtudel ühe korraga. Mitte ainult, et see skript saab kasutada ka siis, kui meil on pidev integratsioon lihvitud näiteks. Hudson. Our following sample code illustrates how to use ANT with JUNIT.
LISTING 2: A Sample java file
[Code]
package com.home.junit;
avalik klass SampleAdd {
avalik int lisama(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;
avalik klassi 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

When we run this script, kõigepealt koostada kood baasi ja siis jookseb rongid testid kompileeritud koodi ja lõpuks tekitab katseprotokolli. The test report can be generated in any format. For convenience we have generated this in XML format.
