This provides SimpleTests for the core file handling functionality. These include FileValidateTest and FileSaveTest.

Code

function testOverwriteSelf() {
  // Create a file for testing.
  $file = $this->createFile();

  // Move the file onto itself without renaming shouldn't make changes.
  $new_filepath = file_unmanaged_move($file->uri, $file->uri, FILE_EXISTS_REPLACE);
  $this->assertFalse($new_filepath, t('Moving onto itself without renaming fails.'));
  $this->assertTrue(file_exists($file->uri), t('File exists after moving onto itself.'));

  // Move the file onto itself with renaming will result in a new filename.
  $new_filepath = file_unmanaged_move($file->uri, $file->uri, FILE_EXISTS_RENAME);
  $this->assertTrue($new_filepath, t('Moving onto itself with renaming works.'));
  $this->assertFalse(file_exists($file->uri), t('Original file has been removed.'));
  $this->assertTrue(file_exists($new_filepath), t('File exists after moving onto itself.'));
