android - How do you call Robolectric's ShadowWifiManager.setScanResults()? -

during testing, need make wifimanager.getscanresults() method return non-empty list. i'm using robolectric. found shadowwifimanager has setscanresults() method, takes list of scanresult objects -- don't have public constructor.

i found robolectric has shadow of scanresult, also, has newinstance method. can used this:

shadowof(((wifimanager)controller.get().getsystemservice(context.wifi_service))).setscanresults(collections.singletonlist(shadowscanresult.newinstance("foo", "bar", "", 1, 2))); 

or, more verbosely: final int level = 5; final int frequency = 100; final scanresult scanresult = shadowscanresult.newinstance( "a fake ssid", "a fake bssid", "some capabilities", level, frequency); final context context = controller.get(); final wifimanager wifimanager = (wifimanager) context.getsystemservice(context.wifi_service); shadowof(wifimanager).setscanresults(collections.singletonlist(scanresult));
