"What is the correct alternative to resetting a mock after setup in Mockito?",
"I'm new to unit testing and trying to learn the proper style. I like to setup the object that I am testing so that I can test it as if it were in use instead of only testing a newly constructed object. I can't test removing things from an object that is empty, as many objects are when constructed.\n\nTake the following for an example where ObservedList is being tested and ListListener is a necessary class that is being mocked.\n\npublic final class ObservedListTest {\n private ListListener<Integer> listener;\n private ObservedList<Integer> list;\n @BeforeMethod public void setup() {\n listener = mock(ListListener.class);\n list = new ObservedList<Integer>(listener);\n list.addAll(Arrays.asList(1,2,3));\n reset(listener);\n }\n @Test public void addFirst() {\n list.add(0, -1);\n verify(listener).listEdited(list, 0, 1, Collections.<Integer>emptyList());\n verifyNoMoreInteractions(listener);\n }\n @Test void addAtEnd() {\n list.add(9);\n verify(listener).listEdited(list, 3, 4, Collections.<Integer>emptyList());\n verifyNoMoreInteractions(listener);\n }\n @Test void removeMiddle() {\n list.remove(Integer.valueOf(2));\n verify(listener).listEdited(list, 1, 1, Collections.singletonList(2));\n verifyNoMoreInteractions(listener);\n }\n}\n\n\nAs a novice this seems to work well to me, but I know that it's bad practice because it uses the reset method. I call reset because I don't want the actual tests to get confused due to interactions that happened in the setup.\n\nThe javadoc for reset doesn't even get around to telling you what the method does because it is so busy telling you that you shouldn't use it. Ordinarily I'd simply take that advice and avoid reset by removing my setup method and adjusting my tests to look more like this:\n\n @Test void removeMiddle() {\n listener = mock(ListListener.class);\n list = new ObservedList<Integer>(listener);\n list.addAll(Arrays.asList(1,2,3));\n list.remove(Integer.valueOf(2));\n InOrder inOrder = inOrder(listener);\n inOrder.verify(listener).listEdited(list, 0, 3,\n Collections.<Integer>emptyList());\n inOrder.verify(listener).listEdited(list, 1, 1,\n Collections.singletonList(2));\n verifyNoMoreInteractions(listener);\n }\n\n\nThis also seems to work well to me. The problem is that the documentation for the reset method says:\n\n\n Instead of reset() please consider writing simple, small and focused\n test methods over lengthy, over-specified tests.\n\n\nI respect that Mockito is designed to encourage good style in unit tests and I want to learn from it, but I'm having a hard time sorting out what message it is trying to send me. When I eliminate reset from my tests, my tests get complex, longer and less focused, so obviously I'm doing it wrong.\n\nWhat does doing it right look like?"

"How does Android support library work with target SDK level?",
"I understand that I can use support libraries to add elements that aren't natively available. However, does the newest SDK version (Lollipop, for example) use these support libraries as well, or does it use native elements? E.g. if I run the app on a Lollipop device, will it use native or support elements? I'm asking because, when editing source code (in Android Studio), I'm only editing one version of the file, I can't, for example, chose to create one file for ICS, and other for Lollipop, so how does the system know which elements to use?"

"Adding dummy variables in panel linear model (regression) in R",
"I have a categorical independent variable (with options of \"yes\" or \"no\") that I want to add to my panel linear model. According to the \n answer here: After generating dummy variables?, the lm function automatically creates dummy variables for you for categorical variables.\n\nDoes this mean that creating dummy variables through i.e. dummy.data.frame is unnecessary, and I can just add in my variable in the plm function and it will automatically be treated like a dummy variable (even if the data is not numerical)? And is this the same for the plm function?\n\nAlso, I don't have much data to begin with. Would it hurt if I manually turned the data into numbers (i.e. \"yes\"=1, \"no\"=0) without creating a dummy variable?"

If I take this em-dash out by renaming the file, then the call to StgOpenStorage() succeeds.\n\nSo my question is this: is this a known limitation with this function? Are there likely to be other Windows SDK functions that fail with special characters like em-dash? I noticed there is a call to mbstowcs() prior to calling this function, which makes me wonder if the problem is due to the code-page mapping the em-dash character incorrectly. The wchar path looks okay in the Visual Studio debugger prior to the call, so it seems weird that the function would fail on a path that the system allows."

"Is it bad practice to bind a view directly to a service property?",

The function is invoked in both cases, upon Ctrl+O and a button click, but a file browsing dialog appears only in the latter. When I debug it, the dialog pops up when fileInput.click() is executed.

"Calculating hand values in Blackjack",

If the player has three cards and one ace, then if the sum of the cards is <= 10 the ace will have value of 11, otherwise it will have a value of 1.\n\nNow lets assume I do not know how many aces the player has got and the game is implemented giving the possibility to the dealer to use more than one deck of cards. The user may have in one hand even 5, 6, 7, 8... aces.\n\nWhat is the best way (possibly using Linq) to evaluate all the aces the player has got to get the closest combination to 21 (in addition to the other cards)?\n\nI know the players' cards and I want to calculate their values, using the aces to reach the closest value to 21."

"Java inheritance, anonymous inner class instance member, android callback method",
"I'm doing this in the context of Android, but my problem is understanding Java. I'm somewhat new to both, so hopefully I'm using the correct terminology here.\n\nI've got a number of sub-classes inheriting/extending from my super class (an Android Activity extension) called SuperActivity. I've also defined another class type called Network (which is an Android Service). In my superclass I'm defining an anonymous inner class that implements an (Android) interface called ServiceConnection. That interface specifies (and therefore I'm defining) methods that will be called by the Android system. I have to pass an instance of that anonymous, ServiceConnection-implementing inner class of mine to a method called bindService(), so that the methods inside that anonymous, inner class can be called later.\n\nAs I mentioned, I'm subclassing that super-class that defines the anonymous inner class. The methods in that anonymous inner class have to set an instance variable in the subclass instance; that instance variable I need to set is here called mNetwork.\n\nIn the superclass:\n\npublic class SuperActivity extends Activity {\n protected Network mNetwork;\n\n protected ServiceConnection mConnection = new ServiceConnection() {\n @Override\n public void onServiceConnected(ComponentName name, IBinder service) {\n mNetwork = ((Network.NetworkBinder)service).getService();\n }\n }\n\n void bindNetwork() {\n bindService( new Intent(this, Network.class), mConnection, Context.BIND_AUTO_CREATE);\n }\n}\n\n\nSo I create my subclass and call its bindNetwork() method. and apparently the anonymous inner class assigned to mConnection is not an instance member of my subclass, since after the OnServiceConnected() method defined in the anonymous inner class is called, the subclass's instance member called mNetwork is null.\n\nFurther, if I take that mConnection variable holding the anonymous inner class and call getClass().getName() on it or toString() on it, it shows itself to be an inner class of my superclass, and not of the subclass.\n\nObviously I'm not understanding something about java inheritance. I want to have a number of subclasses, each with its own mNetwork variable set by the method inside the anonymous inner class. I don't want to cut and past the definition of the anonymous inner class into each subclass. There's got to be a way. What am I doing wrong?"

"Saving and recalling an image with a placeholder image as default in android",
"I currently have a questionnaire, where each question is added dynamically in a db, which the app then receives for instructions. When it uses the camera, it sets the image just fine, using the code:\n\nvoid setResponse(Bitmap image) {\n captureButton.setImageBitmap(image);\n}\n\n\nSimple enough, right? When I click update, to save it to the sqlite db, I save it as a base64 string using this:\n\nString getResponse() {\n String response = \"\";\n try \n {\n Bitmap bitmap = Bitmap.createBitmap(captureButton.getDrawingCache());\n ByteArrayOutputStream stream = new ByteArrayOutputStream();\n bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream);\n byte[] image = stream.toByteArray();\n response = Base64.encodeToString(image, 0);\n } \n catch (Exception e) \n { \n Log.e(\"Capture image error\", e.getMessage());\n e.printStackTrace();\n }\n return response;\n}\n\n\nAnd then when I go back into the questionnaire, if it has data already, it just loads it up using this:\n\nvoid setResponse(String response) {\n byte[] decodedString = Base64.decode(response, Base64.DEFAULT);\n Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);\n captureButton.setImageBitmap(decodedByte);\n}\n\n\nI currently have pretty much the same system for signatures using the gestureOverlayView. But for this, I have a placeholder image defined in the CameraQuestionView.xml file:\n\n <ImageView\n android:layout_width=\"wrap_content\"\n android:layout_height=\"wrap_content\"\n android:layout_margin=\"10dp\"\n android:src=\"@drawable/placeholder\"\n android:id=\"@+id/cameraQuestionCaptureButton\"/>\n\n\nBut for some reason, when loading back up, the placeholder image is displayed instead of the saved image in the db. I tried invalidating the view, but that didn't work either. \n\nThanks!"

"Weird UITableView behavior after expand/collapse the last cell",
"What I want to achieve is that: cell can expand/collapse when clicking on the label inside of it. The cell size should be remembered so that when the user scrolls back to the cell, it should be the size it is used to be. I setup the cell using Auto Layout with all the views assigned height constraint. When the user clicks on the label, I change the cell height by changing the label's height constraint:\n\nfunc triggerExpandCollapse(_ cell: UITableViewCell) {\n guard let cell = cell as? ActivityTableViewCell, let indexPath = self.activitiesTableView.indexPath(for: cell) else { return }\n\n if !self.expandedCellIndex.insert(indexPath.row).inserted {\n self.expandedCellIndex.remove(indexPath.row)\n cell.descLabelHeightConstraint.constant = 60\n }\n else {\n cell.descLabelHeightConstraint.constant = cell.descLabel.intrinsicContentSize.height\n }\n\n self.activitiesTableView.beginUpdates()\n self.activitiesTableView.endUpdates()\n}\n\n\nAnd also config the cell's height before returning every cell:\n\nfunc tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {\n let cell = tableView.dequeueReusableCell(withIdentifier: Constants.TableViewCellID.activity, for: indexPath)\n guard let activityCell = cell as? ActivityTableViewCell else {\n return cell\n }\n\n activityCell.delegate = self\n if self.expandedCellIndex.contains(indexPath.row) {\n activityCell.descLabelHeightConstraint.constant = activityCell.descLabel.intrinsicContentSize.height\n }\n else {\n activityCell.descLabelHeightConstraint.constant = 60\n }\n activityCell.layoutIfNeeded()\n return activityCell\n}\n\n\nI also enable auto layout by:\n\nself.activitiesTableView.rowHeight = UITableViewAutomaticDimension\nself.activitiesTableView.estimatedRowHeight = 1000\n\n\nSo far the cells can expand/collapse with normal scroll behavior except the last one! When I expand the last one and scroll up, the activitiesTableView looks \"jumping\" a short distance. Detail can refer to the video\n\nI have no idea how to debug right now. Does anyone have some ideas about it? Thanks."
