Question

I would like to know what’s the best approach to test the method “pushEvent()” in the following class with a jUnit test.
My problem is, that the private method “callWebsite()” always requires a connection to the network. How can I avoid this requirement or refactor my class that I can test it without a connection to the network?

class MyClass {

    public String pushEvent (Event event) {
        //do something here
        String url = constructURL (event); //construct the website url
        String response = callWebsite (url);

        return response;
    }

    private String callWebsite (String url) {
        try {
            URL requestURL = new URL (url);
            HttpURLConnection connection = null;
            connection = (HttpURLConnection) requestURL.openConnection ();


            String responseMessage = responseParser.getResponseMessage (connection);
            return responseMessage;
        } catch (MalformedURLException e) {
            e.printStackTrace ();
            return e.getMessage ();
        } catch (IOException e) {
            e.printStackTrace ();
            return e.getMessage ();
        }
    }

}

Possible solution: You can extend this class, override callWebsite (you have to make it protected for this purpose) – and the override method write some stub method implementation.
