### Question:
WebElementConditions extends AbstractObjectConditions<FluentWebElement> implements FluentConditions { @Override @Negation public WebElementConditions not() { return (WebElementConditions) super.not(); } WebElementConditions(FluentWebElement element);  WebElementConditions(FluentWebElement element, boolean negation); @Override @Negation WebElementConditions not(); @Override boolean present(); @Override boolean clickable(); @Override boolean stale(); @Override boolean displayed(); @Override boolean enabled(); @Override boolean selected(); @Override StringConditions attribute(String name); @Override StringConditions id(); @Override StringConditions name(); @Override StringConditions tagName(); @Override StringConditions value(); @Override StringConditions text(); @Override StringConditions textContent(); @Override RectangleConditions rectangle(); @Override boolean className(String className);  }### Answer:
@Test public void isVerified() { 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(); }
