        byte[] buffer = new byte[10];

        // The readn method will return 0 when stream returns -1
        // So this should still throw IOException, not return -1
        IOException exception = assertThrows(IOException.class, () -> {

That way, you can create a token with an expiration of, let's say, 1 week. And then when the user comes back the next day with the token, you know that user is still logged in to your system.
