import com.amos.digital.lounge.web.controller.Foo;

@RunWith(MockitoJUnitRunner.class)
public class FooTest {

    @Mock
    Foo foo = new Foo();

    String[] strings;

    @Test
    public void Bar_Blah_Blah() {
        int blah = foo.bar(2, "cat", "rat", "fox", "oct");
        assertTrue(blah == 99);
    }

    @Before
    public void setup() {
        when(foo.bar(anyInt(), Matchers.<String> anyVararg())).thenReturn(99);
    }
}
