public class BDDMockito extends Mockito
Start learning about BDD here: http://en.wikipedia.org/wiki/Behavior_Driven_Development
The problem is that current stubbing api with canonical role of when word does not integrate nicely with //given //when //then comments.
It's because stubbing belongs to given component of the test and not to the when component of the test.
Hence BDDMockito
class introduces an alias so that you stub method calls with given(Object)
method.
Now it really nicely integrates with the given component of a BDD style test!
Here is how the test might look like:
import static org.mockito.BDDMockito.*; Seller seller = mock(Seller.class); Shop shop = new Shop(seller); public void shouldBuyBread() throws Exception { //given given(seller.askForBread()).willReturn(new Bread()); //when Goods goods = shop.buyBread(); //then assertThat(goods, containBread()); }Stubbing voids with throwables:
//given willThrow(new RuntimeException("boo")).given(mock).foo(); //when Result result = systemUnderTest.perform(); //then assertEquals(failure, result);
One of the purposes of BDDMockito is also to show how to tailor the mocking syntax to a different programming style.
