### Question:
UpdateSiteAccessor { static String readRelativeTargetPlatformFeatureJarUrl(String siteUrl, String targetJarUrlPrefix, Proxy proxy) { try { URL url = new URL(siteUrl); if (proxy != null) { LoggingSupport.logInfoMessage("Using proxy (" + proxy.address() + ") for getting the targetplatform feature at URL " + siteUrl); } URLConnection connection = proxy != null ? url.openConnection(proxy) : url.openConnection(); InputStream siteInputStream = connection.getInputStream(); return extractRelativeTargetPlatformFeatureJarUrl(siteInputStream, targetJarUrlPrefix); } catch (IOException e) { LoggingSupport.logErrorMessage(e.getMessage(), e); return null; } }    }### Answer:
@Test public void testReadRelativeUrl() { try { URL resource = getClass().getResource(SITE_TEST_XML); String jarPath = UpdateSiteAccessor.readRelativeTargetPlatformFeatureJarUrl(resource.toURI().toString(), JAR_PREFIX, null); assertThat(jarPath, equalTo(JAR_PATH)); } catch (URISyntaxException e) { fail(e.getMessage()); } }
