1. Install ant {something like C:\Junit\Ant\apache-ant-1.8.4-bin\apache-ant-1.8.4 say it ANT_HOME}
2, Install Junit {remember to set classpath example C:\Junit\junit4.8.1\junit4.8.1 in classpath}
3. copy junit.x.x.jar in ANT_HOME/lib
4. Now you working folder ex C:\Junit\Ant_project
5. Create test and src folder in it and put .java file in src folder
6. example file 1:
public class Subscription {
private int price ; // subscription total price in euro-cent
private int length ; // length of subscription in months
// constructor :
public Subscription(int p, int n) {
price = p ;
length = n ;
}
/**
* Calculate the monthly subscription price in euro,
* rounded up to the nearest cent.
*/
public double pricePerMonth() {
double r = (double) price / (double) length ;
return r ;
}
/**
* Call this to cancel/nulify this subscription.
*/
public void cancel() { length = 0 ; }
}
