Tests the file_save_data() function.

Code

function testExistingReplace() {
    // Setup a file to overwrite.
    $existing = $this->createFile();
    $contents = $this->randomName(8);
    $result = file_save_data($contents, $existing->uri, FILE_EXISTS_REPLACE);
    $this->assertTrue($result, 'File saved successfully.');
    $this->assertEqual('public', file_uri_scheme($result->uri), "File was placed in Drupal's files directory.");
    $this->assertEqual($result->filename, $existing->filename, 'Filename was set to the basename of the existing file, rather than preserving the original name.');
    $this->assertEqual($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(
        'load',
        'update',
    ));
    // Verify that the existing file was re-used.
    $this->assertSameFile($existing, $result);
    // Verify that what was returned is what's in the database.
    $this->assertFileUnchanged($result, file_load($result->fid, TRUE));
