For example, this code:

List actual = Arrays.asList(“name=Joe”,”starsign=Virgo”,”sex=Male”);
assertThat(actual, Matchers.contains(“name=Joe”, “starsign=Libra”, “sex=Female”));

will generate:

Expected: iterable over ["name=Joe", "starsign=Libra", "sex=Female"]
but: item 1: was “starsign=Virgo”

Most of the time it’s true, but when it’s not you’re getting a bad test result.
