How to assert that some String contains at least one value from the List ?

Question

I'm testing some UI functionality with Java and AssertJ. So when I receive some massive string from UI, I should verify if that String contains at least one predefined value from List<String>. It is easy to do opposite thing - verify if list contains at least once some String value but this is not my case. I can't find solution in standard methods.

public static final List<String> OPTIONS = Arrays.asList("Foo", "Bar", "Baz");

String text = "Just some random text with bar";

what I need is smth like this :

Assertions.assertThat(text)
                .as("Should contain at least one value from OPTIONS ")
                .containsAnyOf(OPTIONS)

.matches(s -> OPTIONS.stream().anyMatch(option -> s.contains(option)));

or also `.matches(s -> OPTIONS.stream().anyMatch(s::contains));` – Youcef LAIDANI Apr 06 '19 at 14:42

You can also try to use Condition and AssertJ assertions like areAtLeastOne(), areAtLeast(), for instance:

assertThat(OPTIONS)
.areAtLeastOne(new Condition<>(text::contains,
                                String.format("Error message '%s'", args);

Another option using AssertJ

assertThat(text.split(" ")).containsAnyElementsOf(OPTIONS);

Another simplified option using AssertJ:

.matches(s-> Stream.of("Foo", "Bar", "Baz").anyMatch(s::contains));
