IT Tools and Technologies with Examples: Cobertura Java Ant-Maven Eclipse Example

In this example we will discussed how to add jar file's instead of class. Why this is require, as most of time we are generating the .ear, .war file for application deployment and that time we won't find the any class dir in project.

Requirement:
1. Maven
2. Ant
3. Java
4. Eclipse

> Create the java project with maven command
C:\>mvn archetype:generate -DgroupId=com.tutorialbyexample -DartifactId=mavenjavaexample -DarchetypeArtifactId
=maven-archetype-quickstart -DinteractiveMode=false

Note: assuming you have set the path and class path of maven, ant and java

e.g:

set classpath=%;C:\apache-maven-3.2.1\lib;

set path=%;C:\apache-maven-3.2.1\bin;

> Now with help of above mavenjavaexample project will created

mavenjavaexample

- src

-- main

---java

--test

---java

- pom.xml

App.java

package com.tutorialbyexample;

/**

* Hello world!

public class App

{

public static void main( String[] args )

{

System.out.println( "Hello World!" );

}

AppTest.java

package com.tutorialbyexample;

import junit.framework.Test;

import junit.framework.TestCase;

import junit.framework.TestSuite;

/**

* Unit test for simple App.

public class AppTest

extends TestCase

{

/**

* Create the test case

* @param testName name of the test case

public AppTest( String testName )

{

super( testName );

}

/**

* @return the suite of tests being tested

public static Test suite()

{

return new TestSuite( AppTest.class );

}

/**

* Rigourous Test :-)

public void testApp()

{

assertTrue( true );

}

What we need now just create another project for cobertura:

Create simple project in Eclipse:Cobetura-Java-Coverage-Report-mvn

More more details refer the http://www.tutorialbyexample.com/2015/03/cobertura-java-ant-eclipse-example.html

Now do the required change in:
cobertura.properties:
lib.dir=C:/Cobetura-Java-Coverage-Report-mvn/lib
instrumented.dir=C:/Cobetura-Java-Coverage-Report-mvn/instrumented
coverage.html.dir=C:/Cobetura-Java-Coverage-Report-mvn/htmlReports
src.module1.dir=C:/mavenjavaexample/src/main/java
target.module1.dir=C:/mavenjavaexample/target

build.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<project name="Cobetura-Java-Coverage-Report" default="GeneratingCoberturaFiles" basedir=".">
<property file="cobertura.properties" />
<property name="lib.dir" value="${lib.dir}" />

<property name="instrumented.dir" value="${instrumented.dir}" />
<property name="coverage.html.dir" value="${coverage.html.dir}" />
<property name="src.module1.dir" value="${src.module1.dir}" />
<property name="target.module1.dir" value="${target.module1.dir}" />
<path id="cobertura.classpath">
<fileset dir="${lib.dir}">
<include name="*.jar" />
</fileset>
</path>
<taskdef classpathref="cobertura.classpath" resource="tasks.properties" />
<target name="init">
<delete dir="${instrumented.dir}" />
<delete dir="${coverage.html.dir}" />
<delete file="cobertura.ser" />
<mkdir dir="${instrumented.dir}" />
<mkdir dir="${coverage.html.dir}" />
</target>
<target name="GeneratingCoberturaFiles" depends="init" description="Generating the .ser file with .class file">
<cobertura-instrument todir="${instrumented.dir}" datafile="cobertura.ser">
<ignore regex="org.apache.log4j.*" />

<fileset dir="${target.module1.dir}">
<include name="*.jar" />
</fileset>
</cobertura-instrument>
</target>
<target name="GenerateHTMLReport" description="Generate coverage report">
<delete dir="${coverage.html.dir}" />
<mkdir dir="${coverage.html.dir}" />
<cobertura-report format="HTML" destdir="${coverage.html.dir}" datafile="cobertura.ser">
<fileset dir="${src.module1.dir}">
<include name="**/*.java" />
</fileset>
</cobertura-report>
</target>
</project>

Now open the build.xml in ant view and run it ant GeneratingCoberturaFiles
