Moles Stub types

The Moles Framework. The need for a stub framework that could be effectively used with Pex initially motivated the creation of the Moles framework for generating stub types and mole types:

•  Stub types make it easy to test code that consumes interfaces, or non-sealed classes with overridable methods.
•  Mole types allow detouring of hard-coded dependencies on static or non-overridable methods.

Stub types sample.

public interface IStudent
{
　　string GetName(string name);
}

public class ImpIStudent : StubBase, IStudent
{
　　public Func<string, string> GetNameString;
　　public string GetName(string name)
　　{
　　　　if (GetNameString != null)
　　　　{
　　　　　　return GetNameString("str");
　　　　}
　　　　return null;
　　}
}

[TestMethod()]
public void GetNameTest()
{
　　IStudent target = CreateIStudent();
　　string expected = "name...";

　　var istu = new ClassLibrary1.Moles.SIStudent()
　　{
　　　　GetNameString = (name) => { return expected; }
　　};

　　IStudent stu = istu;

　　string actual = stu.GetName(expected);

　　Assert.AreEqual(expected, actual);

}
