INonPublicFakerNextInstance Method (Type, Members, ActionMethodCallContext)

Object NextInstance(
	Type type,
	Members behavior,
	Action<MethodCallContext> doInstead
)

Function NextInstance ( 
	type As Type,
	behavior As Members,
	doInstead As Action(Of MethodCallContext)
) As Object

Parameters

type

Type: SystemType
The type of the fake instance to be created.

behavior

Type: TypeMock.ArrangeActAssertMembers
Can be one of the following values:

Members Value	Description
Members.MustSpecifyReturnValues	All void calls are ignored. Unless using WhenCalled(Action) on methods that return values and properties, they will throw a TypeMockException.
Members.ReturnNulls	All void calls are ignored. Unless using WhenCalled(Action) on methods that return values and properties, they will return null values (or zero for value types).
Members.CallOriginal	All methods are called. Use WhenCalled(Action) to change this behavior.
Members.ReturnRecursiveFakes	Default. All void calls are ignored. When calling the fake's methods returning values or properties, they will return a fake value, which presents this behavior recursively. Any deep call will never return a Null value.

doInstead

Type: SystemActionMethodCallContext
The action to run at the start of the constructor.

Return Value

[TestMethod]
[Isolated]
public void FakeAFutureInstance_StubIncrementMethod()
{
    bool flag = false;

    RealLogger fake = Isolate.NonPublic.Fake.NextInstance(typeof(RealLogger), Members.ReturnRecursiveFakes, context => flag = true);

    // This object is swapped with the fake
    RealLogger logger = new RealLogger();

    Assert.IsTrue(flag);
}
