One of the tests below is not working. Why?
public class SortedInterfacesTest {
private static final Logger log = LoggerFactory.getLogger(SortedInterfacesTest.class);
<T> void forAll(Consumer<T> consumer, T... values) { }
@Test
public void firstTest() {
forAll(Shape::draw, new MyShape(), new Universal());
}
@Test
public void secondTest() {
log.info("\njava.version {}", System.getProperty("java.version"));
forAll(Picture::draw, new MyPicture(), new Universal());
}
interface Shape { void draw(); }
interface Marker { }
interface Picture { void draw(); }
class MyShape implements Marker, Shape { public void draw() {} }
class MyPicture implements Marker, Picture { public void draw() {} }
class Universal implements Marker, Picture, Shape { public void draw() {} }
}
After all, a pair of Shape and MyShape a symmetric pair of Picture and MyPicture.
Second test fails with the following error(use cli: mvn.exe test):
