A Functional Interface (aka Single Abstract Method type or SMA) is any interface that contains only one abstract method. But it may contain some static or/and default methods.java.lang.Runnableis an example of a Functional Interface, as it have only onerun()method, which is abstract. Similar...
Functional testing mainly involves black box testing and it is not concerned about the source code of the application. This testing checks User Interface, APIs, Database, Security, Client/Server communication and other functionality of the Application Under Test. The testing can be done either manua...
First, since it’s one of the most common interfaces, let’s implementIDisposable. This example isn’t going to be functional, but it’ll give you an idea of how to use an interface. using System; namespace Submain { public class UserData : IDisposable ...
