Test renaming when moving onto a file that already exists.

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

Code

function testExistingRename() {
  // Setup a file to overwrite.
  $contents = $this->randomName(10);
  $source = $this->createFile(NULL, $contents);
  $target = $this->createFile();
  $this->assertDifferentFile($source, $target);

  // Clone the object so we don't have to worry about the function changing
  // our reference copy.
  $result = file_move(clone $source, $target->uri, FILE_EXISTS_RENAME);

  // Check the return status and that the contents changed.
  $this->assertTrue($result, t('File moved successfully.'));
  $this->assertFalse(file_exists($source->uri));
  $this->assertEqual($contents, file_get_contents($result->uri), t('Contents of file correctly written.'));

  // Check that the correct hooks were called.
  $this->assertFileHooksCalled(array('move', 'load', 'update'));

  // Compare the returned value to what made it into the database.
  $this->assertFileUnchanged($result, file_load($result->fid, TRUE));
  // The target file should not have been altered.
  $this->assertFileUnchanged($target, file_load($target->fid, TRUE));
  // Make sure we end up with two distinct files afterwards.
  $this->assertDifferentFile($target, $result);

  // Compare the source and results.
  $loaded_source = file_load($source->fid, TRUE);
  $this->assertEqual($loaded_source->fid, $result->fid, t("Returned file's id matches the source."));
  $this->assertNotEqual($loaded_source->uri, $source->uri, t("Returned file path has changed from the original."));
