Q.How to perform unit testing using Junit testing library in java environment.
CLASS TO BE TESTED :
public class
Subscription {
private int price ; // subscription total
price in euro-cent
// constructor :

*/
return r ;
/**
}
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,
*/
public double pricePerMonth() {
double r =((double) price / (double)
length) ;
return r ;
}
/**
* Call this to cancel/nulify this
subscription.
*/
public void cancel() { length = 0 ; }
}
TEST CASE :
import
org.junit.* ;
public class
SubscriptionTest {
@Test
}

private int price ; // subscription total
price in euro-cent
// constructor :
/**
