Example 2 with PosixFileAttributes

use of java.nio.file.attribute.PosixFileAttributes in project buck by facebook.

the class ProjectFilesystemTest method testCreateReadOnlyFileSetsPermissions.

    // The umask may restrict the actual permissions on the filesystem:
    // https://fburl.com/26569549
    // So the best we can do is to check that the actual permissions are a
    // strict subset of the expected permissions.
    PosixFileAttributes attrs = filesystem.readAttributes(path, PosixFileAttributes.class);
    assertTrue(permissions.containsAll(attrs.permissions()));
