### Question:
SignedHeaderAuth implements HttpRequestFilter { @VisibleForTesting String canonicalPath(String path) { path = path.replaceAll("\\/+", "/"); return path.endsWith("/") && path.length() > 1 ? path.substring(0, path.length() - 1) : path; } @Inject  SignedHeaderAuth(SignatureWire signatureWire, @org.jclouds.location.Provider Supplier<Credentials> creds,
         Supplier<PrivateKey> supplyKey, @TimeStamp Provider<String> timeStampProvider, HttpUtils utils, Crypto crypto); HttpRequest filter(HttpRequest input); String createStringToSign(String request, String hashedPath, String contentHash, String timestamp); String sign(String toSign); static final String SIGNING_DESCRIPTION; }### Answer:
@Test void canonicalizedPathRemovesMultipleSlashes() { assertEquals(signing_obj.canonicalPath(" }
@Test void canonicalizedPathRemovesTrailingSlash() { assertEquals(signing_obj.canonicalPath("/path/"), "/path"); }
