Hello,

In the Java class I am in, we are currently learning how to do JUnit testing in Eclipse and I am kinda struggling with it.

Below is what the assignment is all about (with a comment from the professor on how the testWithdraw method should be tested) and the code for Bank. The JUnit class will need to include the setUp and tearDown methods and be defined.

Thank you!

From the professor regarding the testWithdraw() method:

"In order to test withdraw method completely, you should test two situations: (1) balance = minimumBalance && amount > balance (3) balance >= minimumBalance && amount

Therefore, you need two CheckingAccount objects, one with balance =minimumBalance. Since you have created one in setUp method, you just need to declare and create another one (as a local variable) in testWithdraw method. You need to call withdraw method using these two CheckingAccount objects separately. Use assertFalse and assertTrue to check the return value of calling. For the case (3), you should also use assertEquals to check the balance after withdraw. "

Bank code

abstract public class BankAccount {

private int accountNumber;

private double balance;

public BankAccount(int number, double bal)

{

accountNumber = number;

balance = bal;

}

public int getAccountNumber()

{

return accountNumber;

}

public double getBalance()

{

return balance;

}

public boolean withdraw(double amount)

{

if(balance - amount

return false;

else

{

balance = balance - amount;

return true;

}

}

public void deposit(double amount)

{

balance = balance + amount;

}

}

public class CheckingAccount extends BankAccount{

private double minimumBalance;

public CheckingAccount(int acctNum, double balc, double minBalc)

{

super (acctNum, balc);

minimumBalance = minBalc;

}

public boolean withdraw(double amount)

{

if (getBalance()

return false;

else

return super.withdraw(amount);

}

public String createMonthlyStatement()

{

String statement = "Account number: " + getAccountNumber()

+ " Account balance: " + getBalance()

+ " Minimum balance: " + minimumBalance;

return statement;

}

}
