let root: PathBuf = /* obtained elsewhere */;

assert_eq!(read_file(&("$ROOT/index.html".to_string(), root.join("index.html")), "root HTML"),
           Ok("<html>{henlo}</html>".to_string()));
assert_eq!(read_file(&("$ROOT/image.png".to_string(), root.join("image.png")), "image"),
           Err(Error::Parse {
               tp: "UTF-8 string",
               wher: "image".into(),
               more: "stream did not contain valid UTF-8".into(),
           }));
assert_eq!(read_file(&("$ROOT/nonexistant".to_string(), root.join("nonexistant")), "∅"),
           Err(Error::FileNotFound {
               who: "∅",
               path: "$ROOT/nonexistant".into(),
           }));
