Python unit testing Class properties -


i trying figure out if there's way (unit test) verify property , setter called set name attribute.

class dummyname:     def __init__(self):         self.name = ''      @property     def name(self):         return self.name      @name.setter     def name(self, name):         if not isinstance(name, basestring):             raise exception('name must string.')         self.name = name

trying this...

@mock.patch.object(dummyname, 'name', new_callable=propertymock) def testnameproperty(self, mock_name):     mockname = mock()     mock_name.return_value = mockname     dummyname = dummyname()     dummyname.name = 'test_name'     # assert setter called set name     # assert name called name     # assert name 'test_name'

seems name() , setter never accessed. has better idea? thanks!

by using mocks you've overwritten code you're trying test. mocks calls external code under test.

an appropriate test code assert exception raised if pass isn't string. 

def testnameproperty(self):     dummyname = dummyname()     self.assertraises(exception):         dummyname.name = 12345

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
