개미 빌드 자동화
개요:
이 문서에서 우리는 빌드 도구 개미에 대해 논의하고이를 사용하여 우리는 자바 기반 응용 프로그램의 빌드 메커니즘을 자동화 할 수있는 방법. 오늘날의 시대 개미에서 자바 개발의 중요한 부분이되었다. 대부분의 고객은 전달 된 소스 코드의 일부로서 자동화 된 빌드 스크립트를 갖고 싶어요. 그 이유는 작은 스크립팅 지식을 가진 사람이 상세히 애플리케이션을 몰라도 전개 바이너리를 생성 할 수 있도록 앤트 의해 제공된 단순함.
소개:
Apache ant is a generic build tool. '또 다른 깔끔한 도구'에 대한 축약 이름 ANT 스탠드. 이 도구는 UNIX에서 '만들기'유틸리티와 유사하지만 자바를 사용하여 구현됩니다. 그것은 주로 미리 정의되는 응용 프로그램 서버에 생성 된 바이너리를 자바 기반의 소스 코드의 바이너리를 구축하고 배포하는 데 사용됩니다. 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. 이 파일의 기본 이름은 build.xml 파일입니다. 일부 개발자들은 또한 일부 속성 예컨대을 정의하는 속성, 즉 build.properties 파일 사용. 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=”주” 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” />

ANT를 사용하여 자동화:
개미는 자바 개발자들에게 큰 도움을 제공. 거의 모든 자바 개발자는 단위 테스트를 실행하고 응용 프로그램 서버에 배포 할 수 있습니다 진 분산 파일을 생성 돌볼 수있는 스크립트를 좋아합니다. 개미는 코드베이스에 단위 테스트를 수행하는 데 사용되는 자동화 된 스크립트를 실행하는 방법을 제공합니다. Thus, 이 시험 중심의 개발 방식을 사용하는 개발자에 대한 지원을 제공합니다. As we know in test driven development methodology JUNIT is a compulsion, 우리가 한 번에 모든 JUnit 테스트 케이스를 실행하는 자동화 된 스크립트가있는 경우는 항상 추가 장점이다. 뿐만 아니라 우리가있는 경우이 스크립트도 사용할 수 있다는 툴링 연속 통합 예컨대이. 허드슨 강. Our following sample code illustrates how to use ANT with JUNIT.
LISTING 2: A Sample java file
[Code]
package com.home.junit;
공공의 클래스 SampleAdd {
공공의 INT 추가(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;
}
}

LISTING 4: The ANT script to compile and run the JUNIT test
[Code]
<?xml version=”1.0″?>

When we run this script, 먼저 코드베이스를 컴파일하고 컴파일 된 코드에 대한 JUnit 테스트를 실행하고 마지막으로 테스트 보고서를 생성. The test report can be generated in any format. For convenience we have generated this in XML format.
