Using only NUnitLite 1's Assert.AreEqual method, write tests for the Account class that cover the following cases:
- The Deposit and Withdraw methods will not accept negative numbers.
- Account cannot overstep its overdraft limit.
- The Deposit and Withdraw methods will deposit or withdraw the correct amount, respectively.
- The Withdraw and Deposit methods return the correct results.
public class Account
{
public double Balance { get; private set; }
public double OverdraftLimit { get; private set; }
public Account(double overdraftLimit)
{
this.OverdraftLimit = overdraftLimit > 0 ? overdraftLimit : 0;
this.Balance = 0;
}
public bool Deposit(double amount)
{
if (amount >= 0)
{
this.Balance += amount;
return true;
}
return false;
}
public bool Withdraw(double amount)
{
if (this.Balance - amount >= -this.OverdraftLimit && amount >= 0)
{
this.Balance -= amount;
return true;
}
return false;
}
}
Each of the test case methods should be in the Tester class and have the Test attribute.
- The Deposit and Withdraw methods will not accept negative numbers: Wrong answer
- Account cannot overstep its overdraft limit: Wrong answer
- The Deposit and Withdraw methods will deposit or withdraw the correct amount, respectively: Wrong answer
- The Withdraw and Deposit methods return the correct results: Wrong answer
