### Question:
SiteMapFileContentBuilderImpl implements SiteMapFileContentBuilder { @Override public int getSize(final SiteMapEntry entry) { if (isEmpty(entry)) { return 0; } return entry.walk(siteMapEntrySizeVisitor, BASE_ENTRY_LENGTH, URL); }  @Activate void activate(final SiteMapFileContentBuilderImplConfig config); @Override String buildSiteMapIndex(final Resource root, final SiteMapUrlBuilder urlBuilder, final List<? extends List<SiteMapEntry>> splitEntries); @Override int getBaseSiteMapLength(); @Override int getSize(final SiteMapEntry entry); @Override String buildUrlSet(final Collection<SiteMapEntry> entries, final Map<String, String> xmlns);  }### Answer:
@Test public void getSize() { assertEquals(0, model.getSize(entry)); entry.setUrl("URL"); assertEquals(36, model.getSize(entry)); }
