Create(Object, ISpecimenContext)

Creates a new specimen based on a request.

Declaration
public object Create(object request, ISpecimenContext context)
Parameters
Type Name Description
System.Object request

The request that describes what to create.
ISpecimenContext context

A context that can be used to create other specimens.
Returns
Type Description
System.Object

The requested specimen if possible; otherwise a NoSpecimen instance.
Remarks

The request can be any object, but will often be a System.Type or other System.Reflection.MemberInfo instances.

Note to implementers: Implementations are expected to return a NoSpecimen instance if they can't satisfy the request.
