   21 * <p>22 * Here is how the test might look like: 23 * <pre>24 * import static org.mockito.BDDMockito.*;25 * 26 * Seller seller = mock(Seller.class);27 * Shop shop = new Shop(seller);28 * 29 * public void shouldBuyBread() throws Exception {30 *   //given  31 *   given(seller.askForBread()).willReturn(new Bread());32 *   33 *   //when34 *   Goods goods = shop.buyBread();35 *   36 *   //then37 *   assertThat(goods, containBread());38 * }  39 * </pre>40 * 41 * Stubbing voids with throwables:42 * <pre>43 *   //given44 *   willThrow(new RuntimeException("boo")).given(mock).foo();45 *   46 *   //when47 *   Result result = systemUnderTest.perform();48 *   49 *   //then50 *   assertEquals(failure, result);51 * </pre>52 * <p>53 * One of the purposes of BDDMockito is also to show how to tailor the mocking syntax to a different programming style. 54 */55@SuppressWarnings("unchecked")56public class BDDMockito extends Mockito {57    58    /**59     * See original {@link OngoingStubbing}60     */61    public static interface BDDMyOngoingStubbing<T> {62        63        /**64         * See original {@link OngoingStubbing#thenAnswer(Answer)}65         */66        BDDMyOngoingStubbing<T> willAnswer(Answer<?> answer);67        68        /**69         * See original {@link OngoingStubbing#thenReturn(Object)}70         */71        BDDMyOngoingStubbing<T> willReturn(T value);72        73        /**74         * See original {@link OngoingStubbing#thenReturn(Object, Object...)}75         */76        BDDMyOngoingStubbing<T> willReturn(T value, T... values);77        78        /**79         * See original {@link OngoingStubbing#thenThrow(Throwable...)}80         */81        BDDMyOngoingStubbing<T> willThrow(Throwable... throwables);8283        /**84         * See original {@link OngoingStubbing#thenCallRealMethod()}85         */86        BDDMyOngoingStubbing<T> willCallRealMethod();87    }88    89    public static class BDDOngoingStubbingImpl<T> implements BDDMyOngoingStubbing<T> {9091        private final OngoingStubbing<T> mockitoOngoingStubbing;9293        public BDDOngoingStubbingImpl(OngoingStubbing<T> ongoingStubbing) {94            this.mockitoOngoingStubbing = ongoingStubbing;95        }9697        /* (non-Javadoc)98         * @see org.mockitousage.customization.BDDMockito.BDDMyOngoingStubbing#willAnswer(org.mockito.stubbing.Answer)99         */100        public BDDMyOngoingStubbing<T> willAnswer(Answer<?> answer) {101            return new BDDOngoingStubbingImpl<T>(mockitoOngoingStubbing.thenAnswer(answer));102        }103104        /* (non-Javadoc)105         * @see org.mockitousage.customization.BDDMockito.BDDMyOngoingStubbing#willReturn(java.lang.Object)106         */107        public BDDMyOngoingStubbing<T> willReturn(T value) {108            return new BDDOngoingStubbingImpl<T>(mockitoOngoingStubbing.thenReturn(value));109        }110111        /* (non-Javadoc)112         * @see org.mockitousage.customization.BDDMockito.BDDMyOngoingStubbing#willReturn(java.lang.Object, T[])113         */114        public BDDMyOngoingStubbing<T> willReturn(T value, T... values) {115            return new BDDOngoingStubbingImpl<T>(mockitoOngoingStubbing.thenReturn(value, values));116        }117118        /* (non-Javadoc)119         * @see org.mockitousage.customization.BDDMockito.BDDMyOngoingStubbing#willThrow(java.lang.Throwable[])120         */121        public BDDMyOngoingStubbing<T> willThrow(Throwable... throwables) {122            return new BDDOngoingStubbingImpl<T>(mockitoOngoingStubbing.thenThrow(throwables));123        }124125        public BDDMyOngoingStubbing<T> willCallRealMethod() {126            return new BDDOngoingStubbingImpl<T>(mockitoOngoingStubbing.thenCallRealMethod());127        }128    }129    130    /**131     * see original {@link Mockito#when(Object)}132     */133    public static <T> BDDMyOngoingStubbing<T> given(T methodCall) {134        return new BDDOngoingStubbingImpl<T>(Mockito.when(methodCall));135    }136    137    /**138     * See original {@link Stubber}139     */140    public static interface BDDStubber {141        /**142         * See original {@link Stubber#doAnswer(Answer)}143         */144        BDDStubber willAnswer(Answer answer);145        146        /**147         * See original {@link Stubber#doNothing()}148         */
