Nunit Test

與其他框架的比較:

First Unit Test on ASP.NET Core and Nunit

Create App Project

Create Test Project and Add App Project Reference

Write Function and Test it

我們簡單的做一個計算機並提供兩個計算功能，因為呼叫方便用了Lazy實作Singleton Pattern：

using System;

namespace App
{
    public class Calculator
    {

        private static readonly Lazy<Calculator> lazy = new Lazy<Calculator>(() => new Calculator());

        public static Calculator Instance { get { return lazy.Value; } }

        private Calculator()
        {

        }
        
        public int Add(int value1,int value2){
            return value1+value2;
        }

        public int AddWithAutoPlus3(int value1,int value2){
            return value1+value2+3;
        }
    }
}

這邊簡單的寫一個測試如下：

using NUnit.Framework;
using App;

namespace App.Test
{
    [TestFixture]
    public class UnitTest1
    {
        [Test]
        public void Test_Calculator_Add()
        {
            var value1 = 1; 
            var value2 = 2;

            var expected = 3;
            int actual;

            actual = Calculator.Instance.Add(value1,value2);
            Assert.AreEqual(expected,actual);
            Assert.Inconclusive("Test Passed with Basic Values");
        }

        [Test]
        public void Test_Calculator_AddWithAutoPlus3()
        {
            var value1 = 1; 
            var value2 = 2;

            var expected = 6;
            int actual;

            actual = Calculator.Instance.AddWithAutoPlus3(value1,value2);
            Assert.AreEqual(expected,actual);
            Assert.Inconclusive("Test Passed with Basic Values");
        }
    }
}
