FileSaveDataTest

Tests the file_save_data() function.

Code

function testExistingError() {
  $contents = $this->randomName(8);
  $existing = $this->createFile(NULL, $contents);
  // Check the overwrite error.
  $result = file_save_data('asdf', $existing->uri, FILE_EXISTS_ERROR);
  $this->assertFalse($result, 'Overwriting a file fails when FILE_EXISTS_ERROR is specified.');
  $this->assertEqual($contents, file_get_contents($existing->uri), 'Contents of existing file were unchanged.');
  // Check that no hooks were called while failing.
  $this->assertFileHooksCalled(array());
  // Ensure that the existing file wasn't overwritten.
  $this->assertFileUnchanged($existing, file_load($existing->fid, TRUE));
