Examples

This example assumes that the mock has been used, and later we want to verify that a given invocation with specific parameters was performed:
CopyC#
var mock = new Mock<IWarehouse>();
// exercise mock
//...
// Will throw if the test code didn't set the IsClosed property.
mock.VerifySet(warehouse => warehouse.IsClosed);

Exceptions
