I am trying to get Volley working with Robolectric. I can see that my HTTP request is getting called, and parseNetworkResponse is getting called (I'm sending a custom subclass of JsonRequest), but my Listener is NOT getting called. Any advice? Here is a code sample:
@Test
public void testTypeAheadClient() throws Exception {
Robolectric.getFakeHttpLayer().interceptHttpRequests(false);
//mRemoteRequestQueue and mCustomRequest are set up previously
mRemoteRequestQueue.add(mCustomRequest);
}
private static class CustomRequest extends JsonRequest<MyObject> {
public CustomRequest(String url,
Response.Listener<MyObject> listener,
Response.ErrorListener errorListener) {
super(Request.Method.GET, url, null, listener, errorListener);
}
@Override
protected Response<MyObject> parseNetworkResponse(NetworkResponse response) {
System.out.println("in parseNetworkResponse");
try {
MyObject myObject = new MyObject(new JSONArray(new String(response.data, "UTF-8")));
return Response.success(myObject, HttpHeaderParser.parseCacheHeaders(response));
} catch (Exception e) {
e.printStackTrace();
return Response.error(new ParseError(e));
}
}
}
I solved that same problem by replacing the RequestQueue's ResponseDelivery with one that doesn't use the Looper.getMainLooper() but a new Executor. Example code:
public static RequestQueue newRequestQueueForTest(final Context context, final OkHttpClient okHttpClient) {
final File cacheDir = new File(context.getCacheDir(), "volley");
final Network network = new BasicNetwork(new OkHttpStack(okHttpClient));
final ResponseDelivery responseDelivery = new ExecutorDelivery(Executors.newSingleThreadExecutor());
final RequestQueue queue =
new RequestQueue(
new DiskBasedCache(cacheDir),
network,
4,
responseDelivery);
queue.start();
return queue;
}
Note: use Robolectric-2.2-SNAPSHOT, the previous version doesn't play well with Volley.
Hope this helps
