Question

I have created a Hello World program and I am new to C#, My program will print 100 words like that as follow

public static void Main(/*I forgot arguments*/)
{
   string []s=new string [100];
   foreach(string ss in s)
   {
      ss="Hello World";
      Console.WriteLine("{0}\n",ss);      
   }
}

Could you show me step-by-step how to create a test for this program ? Does it need one ? I don’t have an image of how testers do the test. Sorry I am stupid.

I think I have tried my best, no one ever find I find it unworthy to me not to get any help ? I don’t need the class because I forgot the class long ago after the accident.

First of all, you can’t (or – you shouldn’t) test void methods. You are testing the output of the method – which Main does not have. Second thought: you cannot mock (simulate) an Console object. Read some tutorials about mock and mocking.

Sample method with sample test could look similar to this:

public class SimpleCalculator
{
    public int SumTwoNumbers(int number1, int number2)
    {
        return number1 + number2;
    }
}

[TestClass]
public class TestClass
{
    [TestMethod]
    public void Test_SimpleCalculator_SumTwoNumbers_CorrectValues()
    {
        // Arrange
        SimpleCalculator calc = new SimpleCalculator();

        // Act
        int result = calc.SumTwoNumbers(5, 2);

        // Assert
        Assert.AreEqual(7, result);
    }
}

Hope this helped a little.
