Since this test is already running with testNG, we should just use its builtin
functionalities:
@Test(groups = "type_check")
public static void testTypeCheck() {
Map m = Collections.checkedMap(new HashMap<>(), Integer.class,
Integer.class);
Assert.assertThrows(ClassCastException.class, () -> m.merge("key",
"value", (v1, v2) -> null));
Assert.assertThrows(ClassCastException.class, () -> m.merge("key", 3,
(v1, v2) -> v2));
}
In addition, the checked map tests are in general, only checking the map
functionality works without checking if the type checking functionality works.
But adding a comprehensive test for checking functionalites would be much more
work and is out of this patch's scope, so you don't need to worry about it.
