The method I want to test :

public JSONArray weatherRequest(double lon, double lat) {
    try {
        //Public Api:
        // https://api.openweathermap.org/data/2.5/weather?lat={lat}&lon={lon}&appid={API key}
        //access_key = ***
        URL url = new URL("https://api.openweathermap.org/data/2.5/weather?lat="   lat   ".48&lon="   lon   "&appid=***");
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.connect();
        //Check if connect is made
        int responseCode = conn.getResponseCode();
        // 200 OK
        if (responseCode != 200) {
            throw new RuntimeException("HttpResponseCode: "   responseCode);
        } else {
            StringBuilder informationString = new StringBuilder();
            Scanner scanner = new Scanner(url.openStream());
            while (scanner.hasNext()) {
                informationString.append(scanner.nextLine());
            }
            //Close the scanner
            scanner.close();

            //JSON simple library Setup with Maven is used to convert strings to JSON
            JSONParser parse = new JSONParser();
            Object obj = parse.parse(String.valueOf(informationString));
            JSONArray dataObject = new JSONArray();
            dataObject.add(obj);
            LOG.debug("JSON object: "   dataObject);
            return dataObject;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}

Test Class :

public class MySecondAdapterTest {

    MySecondAdapter mySecondAdapter;

    @Test
        public void testWeatherRequest() {
        JSONArray result = mySecondAdapter.weatherRequest(53.483, -2.29);
        Assert.assertNotNull(result);
    }

}

My getter and setter tests are passing. I'm trying to figure out why the methods unit test is not passing? And any steps I could take to debug for myself in the future. Thanks

Solved by creating an object at the start of test:

MySecondAdapter mySecondAdapter = new MySecondAdapter();
