We will create Class library Project
I. In Class library Project>>Class1.cs file and below are code snippet
namespace BankAccountLibrary
{
public class BackAccount
{
private readonly string CustomerName;
private double balance;
public BackAccount(string cname, double bal)
{
CustomerName = cname;
balance = bal;
}
public string GetCustomerName
{
get
{
return CustomerName;
}
}
public double GetBalance
{
get
{
return balance;
}
}
public void Debit(double amt)
{
if (amt > balance)
throw new ArgumentOutOfRangeException("Insufficient balance. Cannot withdraw");
if (amt <= 0)
throw new ArgumentOutOfRangeException("Amount trying to withdraw is invalid");
//intentionally made a error
balance -= amt;
}
public void Credit(double amt)
{
if (amt <= 0)
throw new ArgumentOutOfRangeException("Amount trying to withdraw is invalid");
balance += amt;
}
}
}
II. In MSUnit Project>>UnitTest1.cs file and below are code snippet
using BankAccountLibrary;
namespace BankAccountMSTest
{
[TestClass]
public class UnitTest1
{
[TestMethod]
public void Debit_WithValidAmount_UpdateBalance()
{
//Arrange
double BeginningBalance = 20.25;
double debitAmount = 4.75;
double expectedBalance = 15.50;
BackAccount acc = new BackAccount("Martin", BeginningBalance);
//Act
acc.Debit(debitAmount);
//Assertion
double actual = acc.GetBalance;
Assert.AreEqual(expectedBalance, actual, 0.001, "Account not debited as data is wrong");
}
}
}
III. In NUnit Project>>UnitTest1.cs file and below are code snippet
using BankAccountLibrary;
namespace BankAccountNUnitTesting
{
public class Tests
{
private BackAccount acc;
[SetUp]
public void Setup()
{
acc = new BackAccount("Martin", 500);
}
[Test]
public void Test_Debit_Method()
{
double amt = 200;
double expected = 400;
acc.Debit(amt);
var actual = acc.GetBalance;
//Assert.AreEqual(expected, actual);
Assert.That(actual, Is.EqualTo(expected));
}
}
}
IV. In XUnit Project>>UnitTest1.cs file and below are code snippet
using BankAccountLibrary;
namespace BankAccountXUnitTesting
{
public class UnitTest1
{
private readonly BackAccount acc;
public UnitTest1()
{
acc = new BackAccount("Martin", 500);
}
[Fact]
public void Test1()
{
//Arrange
var expected = 300;
var amt = 200;
//act
acc.Debit(amt);
var actual = acc.GetBalance;
//assertion
Assert.NotEqual(expected, actual);
}
}
}
