Tests the file_save_data() function.

Code

function testExistingRename() {
  // Setup a file to overwrite.
  $existing = $this->createFile();
  $contents = $this->randomName(8);

  $result = file_save_data($contents, $existing->uri, FILE_EXISTS_RENAME);
  $this->assertTrue($result, "File saved successfully.");

  $this->assertEqual('public', file_uri_scheme($result->uri), "File was placed in Backdrop's files directory.");
  $this->assertEqual($result->filename, $existing->filename, "Filename was set to the basename of the source, rather than that of the renamed file.");
  $this->assertEqual($contents, file_get_contents($result->uri), "Contents of the file are correct.");
  $this->assertEqual($result->filemime, 'application/octet-stream', "A MIME type was set.");
  $this->assertEqual($result->status, FILE_STATUS_PERMANENT, "The file's status was set to permanent.");

  // Check that the correct hooks were called.
  $this->assertFileHooksCalled(array('insert'));

  // Ensure that the existing file wasn't overwritten.
  $this->assertDifferentFile($existing, $result);
  $this->assertFileUnchanged($existing, file_load($existing->fid));

  // Verify that was returned is what's in the database.
  $this->assertFileUnchanged($result, file_load($result->fid));
