/**
* An entry point to classic Mockito stubbing/mocking API with basic matchers.
*
* Created as an alternative approach to static imports. A test class can implement that interface to make all
* the methods from {@link Mockito} class directly available.
*
*
* Sample test in Arrange-Act-Assert style:
*
*
* //no static Mockito imports needed!
*
* class ShopTest implements WithMockito {
*
* private Seller seller = mock(Seller.class);
* private Shop shop = new Shop(seller);
*
* public void shouldBuyBread() {
* //arrange
* when(seller.askForBread()).thenReturn(new Bread());
* //act
* Goods goods = shop.buyBread();
* //assert
* assertThat(goods.containBread()).isTrue();
* }
* }
*
*
* Mock verification can be then performed with {@link Mockito#verify(Object)} method:
*
*
* person.ride(bike);
* person.ride(bike);
*
* verify(person, times(2)).ride(bike);
* verifyNoMoreInteractions(police);
*
*
* In many cases Behavior-driven development style may be preferred. See {@link WithBDDMockito} how it can be used
* with Mockito.
*
* If more sophisticated matchers are needed see {@link WithAdditionalMatchers} interface.
*
* Based on an idea proposed by David Gageot:
* http://blog.javabien.net/2014/04/23/what-if-assertj-used-java-8/
*
* @see WithBDDMockito
* @see WithAdditionalMatchers
