Question

Please Help me on this:

In here I need to call this Add(...) method through the Calling(...) method in MyAnotherClass. When I Assert it gives an error. Please show me the path.

public class MyClass
{
    public List<int> number = new List<int>();

    public void Add(int a, int b)
    {   
        int c = a + b;
        number.Add(c);
    }
 }

public class MyAnotherClass
{
    public void CallingMethod(int c, int d)
    {          
        MyClass mc = new MyClass();
        mc.Add( c, d);
    }
}

[TestClass]
public class UnitTest1
{
    [TestMethod]
    public void TestMethod1()
    {
        MyAnotherClass mac = new MyAnotherClass();

        MyClass mc = new MyClass();

        mc.Add(2, 3);
        Assert.AreEqual(5, mc.number[0]);// **this work fine** 

        mac.CallingMethod(2, 3);
        Assert.AreEqual(5, mc.number[0]);// **but this not**
    }
}

Thanks

Your class, MyAnotherClass returns void, and does not provide a public property from which you can retrieve data from the inner MyClass.

You’d want something like:

public class MyAnotherClass
{
   public MyClass mc = new MyClass();
   public void CallingMethod(int c, int d)
   {
      mc.Add(c, d);
   }
}

Then, in your test class, you’d call mac.mc.number[0] in the comparison.
