can hamcrest "hasItem" get few matchers?

Question

I saw this post

assertThat( myClass.getMyItems(), contains(
    hasProperty("foo", is("bar")), 
    hasProperty("name", is("bar"))
));

and

  assertThat(logsFromWaze, hasItem(
                hasProperty("foo", is("bar")),
                hasProperty("name", is("bar"))));

how can it work?

doesn't hasItem expect one matcher as an argument and not a list of matchers?

There is no `hasItem()` in your code and the `contains()` that you posted accepts vararg parameters. — Thomas, Jul 05 '16 at 10:33
thanks, then how can I check if **at least** one item satisfies 2 matchers for example? — Elad Benda2, Jul 05 '16 at 16:08
It matches few items. I want to find one or more items that satisfies a list of matchers. — Elad Benda2, Jul 06 '16 at 07:21

There is no hasItem matcher that accepts varargs, but you can combine both hasProperty("foo", is("bar")) and hasProperty("name", is("bar")) via allOf matcher:

assertThat(logsFromWaze, hasItem(
        allOf(
                hasProperty("foo", is("bar")),
                hasProperty("name", is("bar"))
        )
));

This test will succeed when a single pass over the examined Iterable yields at least one item that matches all of the matchers passed to allOf.
