Generating a deep object graph based on rules about bogus

[bchavez]

When you call Faker<T>.RuleForType(); it strictly applies to the immediate and top-level declared types of properties or fields of T.

That is, if C.B.A and Faker<C>.RuleForType(A); type C has no immediate field or property of type A and is only indirectly related to A via type of B.

In other words,

void Main()
{
   var c = new CFaker().Generate();
   Debug.Assert(c.B != null, "B is null.");
   Debug.Assert(c.B.A != null, "B.A is null.");
   Debug.Assert(c.B.A.Value != null, "B.A.Value is null.");
   c.Dump();
}

class A
{
   public string Value { get; set; }
}

class B
{
   public A A { get; set; }
}

class C
{
   public B B { get; set; }
}

class CFaker : Faker<C>
{
   public CFaker()
   {
      var bFaker = new BFaker();
      RuleForType(typeof(B), f => bFaker.Generate());
   }
}
class BFaker : Faker<B>
{
   public BFaker()
   {
      RuleForType(typeof(A), f => new A { Value = f.Random.AlphaNumeric(5) });
   }
}
