### Question:
RouteSimilarity { public RouteSimilarity(RouteData routeData, String currentRoute) { this.route = routeData.getNavigationTarget(); this.routeData = routeData; int urlSimilarity = calculateSimilarity(routeData.getUrl(), currentRoute); int routeAliasSimilarity = routeData.getRouteAliases().stream().map(routeAliasData -> calculateSimilarity(routeAliasData.getUrl(), currentRoute)).max(Integer::compareTo).orElse(0); similarity = Math.max(urlSimilarity, routeAliasSimilarity); } RouteSimilarity(RouteData routeData, String currentRoute);  RouteSimilarity(String url, String currentRouteParts); RouteData getRouteData(); Class<? extends Component> getRoute(); String getRouteString(); int getSimilarity();  }### Answer:
@Test public void testRouteSimilarity() { String[] urls = new String[]{ "navigation/view1", "navigation/view2", "navigation/view3", "navigation/view4", "navigation/view5", "navigation/view6", "navigation/view7", "navigation/view8", "navigation/view9", "navigation" }; String currentRoutePart = "navigation"; RouteSimilarity r = Arrays.stream(urls) .map(s -> new RouteSimilarity(currentRoutePart, s)) .max(Comparator.comparingInt(RouteSimilarity::getSimilarity)).get(); String result2 = urls[9]; Assert.assertEquals(r.getRouteString(), result2); }
