### Question:
MemoryRepositoryResolver implements RepositoryResolver { public URI createRootURI(@NonNull String contextName) { final URI base; try { String scheme = "memory"; String host = encodeName(contextName); String path = "/"; String fragment = null; base = new URI(scheme, host, path, fragment); } catch (Exception e) { e.printStackTrace(); throw new RuntimeException(e); } return base; }  static @VisibleForTesting void removeContext(@NonNull String context); static void removeAllContexts(); @Override boolean canHandle(@NonNull URI repoURI); @Override boolean canHandleURIScheme(String scheme); @Override boolean repoExists(@NonNull URI repoURI); @Override URI buildRepoURI(@NonNull URI rootRepoURI, @NonNull String repoName); URI createRootURI(@NonNull String contextName); @Override URI getRootURI(@NonNull URI repoURI); @Override List<String> listRepoNamesUnderRootURI(@NonNull URI rootRepoURI); @Override String getName(@NonNull URI repoURI); @Override void initialize(@NonNull URI repoURI); @Override Repository open(@NonNull URI repositoryURI); @Override Repository open(@NonNull URI repositoryURI, @NonNull Hints hints); @Override boolean delete(@NonNull URI repositoryLocation); @Override ConfigDatabase resolveConfigDatabase(@NonNull URI repoURI,
            @NonNull Context repoContext, boolean rootUri); @Override ObjectDatabase resolveObjectDatabase(@NonNull URI repoURI, Hints hints); @Override IndexDatabase resolveIndexDatabase(@NonNull URI repoURI, Hints hints); @Override RefDatabase resolveRefDatabase(@NonNull URI repoURI, Hints hints); @Override ConflictsDatabase resolveConflictsDatabase(@NonNull URI repoURI, Hints hints);  }### Answer:
public @Test void testCreateRootURI() { assertEquals(URI.create("memory: assertEquals(URI.create("memory: }
