Example 6 with PosixFilePermission

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

the class ProjectFilesystemTest method testCreateReadOnlyFileSetsPermissions.

@Test
public void testCreateReadOnlyFileSetsPermissions() throws IOException {
    Assume.assumeTrue(FileSystems.getDefault().supportedFileAttributeViews().contains("posix"));

    // 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()));
