The deposit method uses an if statement to check if the amount to be deposited is negative. If so, it does nothing, but returns False signifying that the transaction failed.
However, if the test finds out that the amount to deposit is positive or zero, the deposit method increments the balance, then returns True, signifying a successful transaction.
The withdraw method is similar, but this time, it tests if the amount to be withdrawn is greater than the available balance. If so, it ignores the transaction, and returns False.
If the withdrawal amount is less or equal to the available balance, the withdraw method decrements the available balance, then returns True, signifying a successful transaction.
