Sets the raw HTML content. This can be useful when a page has been fetched outside of the internal browser and assertions need to be made on the returned page.
A good example would be when testing drupal_http_request(). After fetching the page the content can be set and page elements can be checked to ensure that the function worked properly.
protected function drupalSetContent($content, $url = 'internal:') {
$this->content = $content;
$this->url = $url;
$this->plainTextContent = FALSE;
$this->elements = FALSE;
$this->drupalSettings = array();
if (preg_match('/var drupalSettings = (.*?);/', $content, $matches)) {
$this->drupalSettings = drupal_json_decode($matches[1]);
}
}
