### Question:
Dom { public FluentList<FluentWebElement> followingSiblings() { return handleAxe("following-sibling"); } Dom(WebElement element, ComponentInstantiator instantiator); FluentWebElement parent(); FluentList<FluentWebElement> ancestors(); FluentList<FluentWebElement> descendants(); FluentList<FluentWebElement> followings(); FluentList<FluentWebElement> followingSiblings(); FluentList<FluentWebElement> precedings(); FluentList<FluentWebElement> precedingSiblings();  }### Answer:
@Test public void testFollowingSiblings() { Dom dom = new Dom(element, instantiator); List<WebElement> elements = Arrays.asList(mock(WebElement.class), mock(WebElement.class), mock(WebElement.class)); when(element.findElements(By.xpath("following-sibling::*"))).thenReturn(elements); assertThat(dom.followingSiblings().toElements()).isEqualTo(elements); }
