$field_name: Name of field or message property to assert: subject, body, id, ...
$regex: Pattern to search for.
$message: (optional) A message to display with the assertion. Do not translate messages: use format_string() to embed variables in the message text, not t(). If left blank, a default message will be displayed.
$group: (optional) The group this message is in, which is displayed in a column in test output. Use 'Debug' to indicate this is debugging output. Do not translate this string. Defaults to 'Other'; most tests do not override this default.
TRUE on pass, FALSE on fail.
