Cobertura, Java, Ant and Eclipse Tutorial

Cobertura:

Cobertura is a free Java tool that calculates the percentage of code accessed by tests. It can be used to identify which parts of your Java program are lacking test coverage. It is based on jcoverage. Click Me

Requirement:
Operating System, Java, Ant, Eclipse and Cobetura.

Note; Download latest cobetura files from http://cobertura.github.io/cobertura/

Create the new java project in eclipse:
Open the eclipse.
File > New > Java Project
Enter the name: cobertura_java_project
Right Click on the src under project cobertura_java_project
New > Class
Enter the:
package name: tutorialbyexample.cobertura.com
Class Name: CoberturaJavaApp.java

CoberturaJavaApp.java file look like as below:

/**
 *
 */
package tutorialbyexample.cobertura.com;
/**
 * @author Vinod Kumar
 *
 */
public class CoberturaJavaApp {
/**
* @param args
*/
public static void main(String[] args) {
CoberturaJavaApp obj = new CoberturaJavaApp();
printData("Welcome " + obj.getName("Vinod")
+ " to learning Cobertura!!!");
}
public String getName(String name) {
return name;
}
public String getAnotherName(String name) {
return name;
}
private static void printData(Object obj) {
System.out.println(obj);
}
}

Run It: Right click on the CoberturaJavaApp.java then Run as > Java Applicaiton
Output: Welcome Vinod to learning Cobertura!!!

Create the another simple project in eclipse: Cobetura-Java-Coverage-Report

    2. Hi everybody,
      I followed the same steps and I am able to generate the reports but not able to see the code coverage.. below is output when I click on line coverage and branch coverage..

      Line coverage:the percentage of lines executed by thid test run
      Branch coverage:the percentage of lines executed by thid test run
      N/A: line coverage and branch coverage will appear as not applicable when cobertura can't find the line number information in the . class file.this happens for stub and skeleton classes, interfaces or when the class was not compiled with debug = true.

    4. Thanks for your info about Cobertura in Java by Ant in eclipse.
      Can you double check for .ser file and you are running application like >
      Run It: Right click on the CoberturaJavaApp.java then Run as > Java Application
      And most of time people use to miss for path and all run the simple program from http://cobertura.github.io/cobertura/
