### Question:
AclAttributeProvider extends AttributeProvider { @NullableDecl @Override public Object get(File file, String attribute) { if (attribute.equals("acl")) { return file.getAttribute("acl", "acl"); } return null; }  @Override String name(); @Override ImmutableSet<String> inherits(); @Override ImmutableSet<String> fixedAttributes(); @Override ImmutableMap<String, ?> defaultValues(Map<String, ?> userProvidedDefaults); @NullableDecl @Override Object get(File file, String attribute); @Override void set(File file, String view, String attribute, Object value, boolean create); @Override Class<AclFileAttributeView> viewType(); @Override AclFileAttributeView view(
      FileLookup lookup, ImmutableMap<String, FileAttributeView> inheritedViews);  }### Answer:
@Test public void testInitialAttributes() { assertThat(provider.get(file, "acl")).isEqualTo(defaultAcl); }
