### Question:
AtLeastOneElementConditions extends AbstractFluentListConditions { @Override public boolean verify(Predicate<FluentWebElement> predicate, boolean defaultValue) { if (isNegation()) { predicate = predicate.negate(); defaultValue = !defaultValue; } return buildAtLeastOnePredicate(predicate, defaultValue).test(null); } AtLeastOneElementConditions(List<? extends FluentWebElement> elements); @Override AtLeastOneElementConditions not(); @Override boolean verify(Predicate<FluentWebElement> predicate, boolean defaultValue);  }### Answer:
@Test public void verify() { assertThat(conditions.verify(predicate -> true)).isTrue(); assertThat(conditions.verify(predicate -> false)).isFalse(); assertThat(conditions.not().verify(predicate -> true)).isFalse(); assertThat(conditions.not().verify(predicate -> false)).isTrue(); }
