### Question:
FluentListAssert extends AbstractFluentAssert<FluentListAssert, FluentList> implements ListStateAssert, ListAttributeAssert { @Override public FluentListAssert hasTextMatching(String regexToBeMatched) { List<String> actualTexts = requiresNonEmpty(actual.texts()); if (actualTexts.stream().noneMatch(text -> text.matches(regexToBeMatched))) { failWithMessage("No selected elements contains text matching: " + regexToBeMatched + ". Actual texts found: " + actualTexts); } return this; } FluentListAssert(FluentList<? extends FluentWebElement> actual); @Override FluentListAssert isEmpty(); @Override FluentListAssert isNotEmpty(); @Override FluentListAssert hasSize(int expectedSize); @Override FluentListSizeBuilder hasSize(); @Override FluentListAssert hasText(String textToFind); @Override FluentListAssert hasTextContaining(String textToFind); @Override FluentListAssert hasTextMatching(String regexToBeMatched); @Override FluentListAssert hasNotText(String textToFind); @Override FluentListAssert hasNotTextContaining(String textToFind); @Override FluentListAssert hasId(String idToFind); @Override FluentListAssert hasClass(String classToFind); @Override FluentListAssert hasClasses(String... classesToFind); @Override FluentListAssert hasNotClass(String htmlClass); @Override FluentListAssert hasNotClasses(String... htmlClasses); @Override FluentListAssert hasValue(String value); @Override FluentListAssert hasName(String name); @Override FluentListAssert hasTagName(String tagName); @Override FluentListAssert hasDimension(Dimension dimension); @Override FluentListAssert hasAttributeValue(String attribute, String value); @Override ListAssert<String> hasAttribute(String attribute); @Override FluentListAssert hasNotAttribute(String attribute);  }### Answer:
@Test public void hasTextMatchingOk() { when(fluentList.texts()).thenReturn(Lists.newArrayList("Pharmacy", "Hospital")); listAssert.hasTextMatching("Pha\\w+cy"); }
@Test public void hasTextMatchingKo() { when(fluentList.texts()).thenReturn(Lists.newArrayList("Pharmacy", "Hospital")); assertThatAssertionErrorIsThrownBy(() -> listAssert.hasTextMatching("Pha\\w+cy\\8")) .hasMessage("No selected elements contains text matching: Pha\\w+cy\\8. " + "Actual texts found: [Pharmacy, Hospital]"); }
