  • Get 1 array from 2 arrays (using RestKit 0.20)

    - by Reez
    I'm using RestKit and was wondering how to combine two array's into one array. I already have the data being pulled in separately from API1 and API2, but I don't know how to combine them into 1 tableView. Each API is pulling in media, and I want the combined tableView to show the most recent media (like any standard timeline does these days). I will post any extra code or help as necessary, thanks so much! Below shows API1 + API2 being pulled in correctly, but not combined into the tableView. Only data from API1 shows in the tableView.

  • resetting the image in an NSView

    - by Josan
    I think this is a very simple question, but I’m new to programming so I may be going about it in a wrong-headed way. I have a basic understanding of Objective-C writing terminal applications and am teaching myself how to use the Cocoa GUI. I understand how to use IBOutlet and IBAction to connect a simple button to a method that will repeatedly send random numbers to a textfield . I understand how to add a NSView file, connect it to a custom view in interface builder and draw a path through random points in the view when the application launches. (I’ve been putting this code inside the - (void)drawRect:(NSRect)dirtyRect method that is declared when the file is created). What I can’t seem to figure out is how to connect a button to an action that will then ‘refresh’ the view – in this case repopulate it with another set of random points connected with a path. Looking at the documentation, I think I should somehow be using – (void) setNeedsDisplay(BOOL)flag but nothing I have tried so far had worked. Please tell me, what am I missing here?

  • How to create file of files?

    - by TheMachineCharmer
    class Node { FooType Data; // I can save Data to file with extension .foo void Save() { // save Data to .foo file } } Now , class Graph { List<Node> Nodes; void Save() { foreach(Node node in Nodes) { node.Save(); } } } Now when I invoke someGraph.Save(); then it creates Nodes.Count number of files. I would like to appear those files as one file with extension somename.graph and be able to read it again as Nodes. How can I do this? Is there a way to bundle files into a single different file?

  • Does this variable need to be declared volatile?

    Does the out variable in the MyThread class need to be declared volatile in this code or will the "volatility" of the stdout variable in the ThreadTest class carry over? import java.io.PrintStream; class MyThread implements Runnable { int id; PrintStream out; // should this be declared volatile? MyThread(int id, PrintStream out) { this.id = id; this.out = out; } public void run() { try { Thread.currentThread().sleep((int)(1000 * Math.random())); out.println("Thread " + id); } catch (InterruptedException e) { e.printStackTrace(); } } } public class ThreadTest { static volatile PrintStream stdout = System.out; public static void main(String[] args) { for (int i = 0; i < 10; i++) { new Thread(new MyThread(i, stdout)).start(); } } }

  • Policy based design and defaults.

    - by Noah Roberts
    Hard to come up with a good title for this question. What I really need is to be able to provide template parameters with different number of arguments in place of a single parameter. Doesn't make a lot of sense so I'll go over the reason: template < typename T, template <typename,typename> class Policy = default_policy > struct policy_based : Policy<T, policy_based<T,Policy> > { // inherits R Policy::fun(arg0, arg1, arg2,...,argn) }; // normal use: policy_base<type_a> instance; // abnormal use: template < typename PolicyBased > // No T since T is always the same when you use this struct custom_policy {}; policy_base<type_b,custom_policy> instance; The deal is that for many abnormal uses the Policy will be based on one single type T, and can't really be parameterized on T so it makes no sense to take T as a parameter. For other uses, including the default, a Policy can make sense with any T. I have a couple ideas but none of them are really favorites. I thought that I had a better answer--using composition instead of policies--but then I realized I have this case where fun() actually needs extra information that the class itself won't have. This is like the third time I've refactored this silly construct and I've got quite a few custom versions of it around that I'm trying to consolidate. I'd like to get something nailed down this time rather than just fish around and hope it works this time. So I'm just fishing for ideas right now hoping that someone has something I'll be so impressed by that I'll switch deities. Anyone have a good idea? Edit: You might be asking yourself why I don't just retrieve T from the definition of policy based in the template for default_policy. The reason is that default_policy is actually specialized for some types T. Since asking the question I have come up with something that may be what I need, which will follow, but I could still use some other ideas. template < typename T > struct default_policy; template < typename T, template < typename > class Policy = default_policy > struct test : Policy<test<T,Policy>> {}; template < typename T > struct default_policy< test<T, default_policy> > { void f() {} }; template < > struct default_policy< test<int, default_policy> > { void f(int) {} }; Edit: Still messing with it. I wasn't too fond of the above since it makes default_policy permanently coupled with "test" and so couldn't be reused in some other method, such as with multiple templates as suggested below. It also doesn't scale at all and requires a list of parameters at least as long as "test" has. Tried a few different approaches that failed until I found another that seems to work so far: template < typename T > struct default_policy; template < typename T, template < typename > class Policy = default_policy > struct test : Policy<test<T,Policy>> {}; template < typename PolicyBased > struct fetch_t; template < typename PolicyBased, typename T > struct default_policy_base; template < typename PolicyBased > struct default_policy : default_policy_base<PolicyBased, typename fetch_t<PolicyBased>::type> {}; template < typename T, template < typename > class Policy > struct fetch_t< test<T,Policy> > { typedef T type; }; template < typename PolicyBased, typename T > struct default_policy_base { void f() {} }; template < typename PolicyBased > struct default_policy_base<PolicyBased,int> { void f(int) {} };

  • How do I create a thread-safe write-once read-many value in Java?

    - by Software Monkey
    This is a problem I encounter frequently in working with more complex systems and which I have never figured out a good way to solve. It usually involves variations on the theme of a shared object whose construction and initialization are necessarily two distinct steps. This is generally because of architectural requirements, similar to applets, so answers that suggest I consolidate construction and initialization are not useful. By way of example, let's say I have a class that is structured to fit into an application framework like so: public class MyClass { private /*ideally-final*/ SomeObject someObject; MyClass() { someObject=null; } public void startup() { someObject=new SomeObject(...arguments from environment which are not available until startup is called...); } public void shutdown() { someObject=null; // this is not necessary, I am just expressing the intended scope of someObject explicitly } } I can't make someObject final since it can't be set until startup() is invoked. But I would really like it to reflect it's write-once semantics and be able to directly access it from multiple threads, preferably avoiding synchronization. The idea being to express and enforce a degree of finalness, I conjecture that I could create a generic container, like so: public class WoRmObject<T> { private T object; WoRmObject() { object=null; } public WoRmObject set(T val) { object=val; return this; } public T get() { return object; } } and then in MyClass, above, do: private final WoRmObject<SomeObject> someObject; MyClass() { someObject=new WoRmObject<SomeObject>(); } public void startup() { someObject.set(SomeObject(...arguments from environment which are not available until startup is called...)); } Which raises some questions for me: Is there a better way, or existing Java object (would have to be available in Java 4)? Is this thread-safe provided that no other thread accesses someObject.get() until after it's set() has been called. The other threads will only invoke methods on MyClass between startup() and shutdown() - the framework guarantees this. Given the completely unsynchronized WoRmObject container, it is ever possible under either JMM to see a value of object which is neither null nor a reference to a SomeObject? In other words, does has the JMM always guaranteed that no thread can observe the memory of an object to be whatever values happened to be on the heap when the object was allocated.

  • How does one implement a truly asynchronous java thread

    - by Ritesh M Nayak
    I have a function that needs to perfom two operations, one which finishes fast and one which takes a long time to run. I want to be able to delegate the long running operation to a thread and I dont care when the thread finishes, but the threads needs to complete. I implemented this as shown below , but, my secondoperation never gets done as the function exits after the start() call. How I can ensure that the function returns but the second operation thread finishes its execution as well and is not dependent on the parent thread ? public void someFunction(String data) { smallOperation() Blah a = new Blah(); Thread th = new Thread(a); th.Start(); } class SecondOperation implements Runnable { public void run(){ // doSomething long running } }

  • Any way to allow classes implementing IEntity and downcast to have operator == comparisons?

    - by George Mauer
    Basically here's the issue. All entities in my system are identified by their type and their id. new Customer() { Id = 1} == new Customer() {Id = 1}; new Customer() { Id = 1} != new Customer() {Id = 2}; new Customer() { Id = 1} != new Product() {Id = 1}; Pretty standard scenario. Since all Entities have an Id I define an interface for all entities. public interface IEntity { int Id { get; set;} } And to simplify creation of entities I make public abstract class BaseEntity<T> : where T : IEntity { int Id { get; set;} public static bool operator ==(BaseEntity<T> e1, BaseEntity<T> e2) { if (object.ReferenceEquals(null, e1)) return false; return e1.Equals(e2); } public static bool operator !=(BaseEntity<T> e1, BaseEntity<T> e2) { return !(e1 == e2); } } where Customer and Product are something like public class Customer : BaseEntity<Customer>, IEntity {} public class Product : BaseEntity<Product>, IEntity {} I think this is hunky dory. I think all I have to do is override Equals in each entity (if I'm super clever, I can even override it only once in the BaseEntity) and everything with work. So now I'm expanding my test coverage and find that its not quite so simple! First of all , when downcasting to IEntity and using == the BaseEntity< override is not used. So what's the solution? Is there something else I can do? If not, this is seriously annoying. Upadate It would seem that there is something wrong with my tests - or rather with comparing on generics. Check this out [Test] public void when_created_manually_non_generic() { // PASSES! var e1 = new Terminal() {Id = 1}; var e2 = new Terminal() {Id = 1}; Assert.IsTrue(e1 == e2); } [Test] public void when_created_manually_generic() { // FAILS! GenericCompare(new Terminal() { Id = 1 }, new Terminal() { Id = 1 }); } private void GenericCompare<T>(T e1, T e2) where T : class, IEntity { Assert.IsTrue(e1 == e2); } Whats going on here? This is not as big a problem as I was afraid, but is still quite annoying and a completely unintuitive way for the language to behave. Update Update Ah I get it, the generic implicitly downcasts to IEntity for some reason. I stand by this being unintuitive and potentially problematic for my Domain's consumers as they need to remember that anything happening within a generic method or class needs to be compared with Equals()

  • Is there an editor that shows WYSIWYG comments?

    - by Bráulio Bezerra
    Has anyone seen an editor/IDE that shows WYSIWYG comments inside the code? I have seen some that show the docs of an element in a separated tab/windows, but not together with code. For example, a JavaDoc comment would be much clearer and easier to edit if it had no tags and could be edited like a snippet from a normal text document. /** * Writes <code>Hello world!</code> to the <b>standard output</b>. * @seealso showGoodbye */ public static void showHello() { Could be something like this: /* Writes Hello world! to the standard output. See also: showGoodbye() */ public static void showHello() { but, editable, of course. And for anyone who happens to have some knowledge/experience with open IDEs like Eclipse, Netbeans, etc.: would it be too hard to implement this?

  • HQL multiple updates. Is there a better way?

    - by folone
    I have a Map, that I want to persist. The domain object is something like this: public class Settings { private String key; private String value; public String getKey() { ... } public String getValue() { ... } public void setKey() { ... } public void setValue() { ... } } The standard approach is to generate a Setting for each pair, and saveOrUpdate() it. But it generates way too much queries, because I need to save lots of settings at a time, and it really affects perfomance. Is there a way to do this using one update query?

  • C++/CLI value class constraint won't compile. Why?

    - by Simon
    Hello, a few weeks ago a co-worker of mine spent about two hours finding out why this piece of C++/CLI code won't compile with Visual Studio 2008 (I just tested it with Visual Studio 2010... same story). public ref class Test { generic<class T> where T : value class void MyMethod(Nullable<T> nullable) { } }; The compiler says: Error 1 error C3214: 'T' : invalid type argument for generic parameter 'T' of generic 'System::Nullable', does not meet constraint 'System::ValueType ^' C:\Users\Simon\Desktop\Projektdokumentation\GridLayoutPanel\Generics\Generics.cpp 11 1 Generics Adding ValueType will make the code compile. public ref class Test { generic<class T> where T : value class, ValueType void MyMethod(Nullable<T> nullable) { } }; My question is now. Why? What is the difference between value class and ValueType?

  • VS 2008 linking error

    - by AvatarBlue
    I'm using Visual Studio 2008 C++ and working on a dll project. Debug compiled and linked perfectly but when I compile the release version, it shows this: VImgPtr.obj : error LNK2001: unresolved external symbol @__security_check_cookie@4 VLibraryPtr.obj : error LNK2001: unresolved external symbol "void __cdecl operator delete[](void *)" (??_V@YAXPAX@Z) D:\Source Code\VImgLib\Release-vc9u\VImgLib-vc9u.dll : fatal error LNK1120: 2 unresolved externals If I selected Multi-threaded (/MT) in "C/C++-Code Generation tab), it linked ok. The problem is only when I choose Multi-threaded DLL (/MD). I'm releasing a dll, so should be /MD right?

    Hi, I'm doing a Facebook App where I'd like to pull out all the possible images from a user's album. What I'm trying to do at the moment is a fql query so that i can find all the images that belong to that specific user. it goes something like that: protected function loadFromFacebook(event:MouseEvent):void { var fql:String = "select src_small from photo where owner = me()"; Facebook.fqlQuery(fql, handleGetPhotosResponse); } private function handleGetPhotosResponse(event:Object, fail:Object):void { if (event != null){ facebookPhotos = new ArrayCollection(event as Array); } } I store this images in an array collection but I don't know how to proceed after that. How can I load those images into, say, a Tile List or a Loader? Any help would be much appreciated, thanks

  • connecting clients to server with emulator on different computers

    - by prolink007
    I am writing an application that communicates using sockets. I have a server running on one android emulator on a computer, then i have 2 other clients running on android emulators on 2 other computers. I am trying to get the 2 clients to connect to the server. This works when i run the server and clients on the same computer, but when i attempt to do this on the same wifi network and on separate computers it gives me the following error. The client and server code is posted below. A lot is stripped out just to show the important stuff. Also, after the server starts i telnet into the server and run these commands redir add tcp:5000:6000 (i have also tried without doing the redir but it still says the same thing). Then i start the clients and get the error. Thanks for the help! Both the 5000 port and 6000 port are open on my router. And i have windows firewall disabled on the computer hosting the server. 11-27 18:54:02.274: W/ActivityManager(60): Activity idle timeout for HistoryRecord{44cf0a30 school.cpe434.ClassAidClient/school.cpe434.ClassAid.ClassAidClient4Activity} 11-27 18:57:02.424: W/System.err(205): java.net.SocketException: The operation timed out 11-27 18:57:02.454: W/System.err(205): at org.apache.harmony.luni.platform.OSNetworkSystem.connectSocketImpl(Native Method) 11-27 18:57:02.454: W/System.err(205): at org.apache.harmony.luni.platform.OSNetworkSystem.connect(OSNetworkSystem.java:114) 11-27 18:57:02.465: W/System.err(205): at org.apache.harmony.luni.net.PlainSocketImpl.connect(PlainSocketImpl.java:245) 11-27 18:57:02.465: W/System.err(205): at org.apache.harmony.luni.net.PlainSocketImpl.connect(PlainSocketImpl.java:220) 11-27 18:57:02.465: W/System.err(205): at java.net.Socket.startupSocket(Socket.java:780) 11-27 18:57:02.465: W/System.err(205): at java.net.Socket.<init>(Socket.java:314) 11-27 18:57:02.465: W/System.err(205): at school.cpe434.ClassAid.ClassAidClient4Activity.onCreate(ClassAidClient4Activity.java:102) 11-27 18:57:02.474: W/System.err(205): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 11-27 18:57:02.474: W/System.err(205): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2459) 11-27 18:57:02.474: W/System.err(205): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2512) 11-27 18:57:02.474: W/System.err(205): at android.app.ActivityThread.access$2200(ActivityThread.java:119) 11-27 18:57:02.474: W/System.err(205): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1863) 11-27 18:57:02.474: W/System.err(205): at android.os.Handler.dispatchMessage(Handler.java:99) 11-27 18:57:02.474: W/System.err(205): at android.os.Looper.loop(Looper.java:123) 11-27 18:57:02.486: W/System.err(205): at android.app.ActivityThread.main(ActivityThread.java:4363) 11-27 18:57:02.486: W/System.err(205): at java.lang.reflect.Method.invokeNative(Native Method) 11-27 18:57:02.486: W/System.err(205): at java.lang.reflect.Method.invoke(Method.java:521) 11-27 18:57:02.486: W/System.err(205): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 11-27 18:57:02.486: W/System.err(205): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 11-27 18:57:02.486: W/System.err(205): at dalvik.system.NativeStart.main(Native Method) The server code public class ClassAidServer4Activity extends Activity { ServerSocket ss = null; String mClientMsg = ""; String mClientExtraMsg = ""; Thread myCommsThread = null; public static final int SERVERPORT = 6000; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TextView tv = (TextView) findViewById(R.id.textView1); tv.setText("Nothing from client yet"); this.myCommsThread = new Thread(new CommsThread()); this.myCommsThread.start(); } class CommsThread implements Runnable { public void run() { // Socket s = null; try { ss = new ServerSocket(SERVERPORT ); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } while(true) { try { Socket socket = ss.accept(); connectedDeviceCount++; Thread lThread = new Thread(new ListeningThread(socket)); lThread.start(); } catch (IOException e) { e.printStackTrace(); } } } } class ListeningThread implements Runnable { private Socket s = null; public ListeningThread(Socket socket) { // TODO Auto-generated constructor stub this.s = socket; } @Override public void run() { // TODO Auto-generated method stub while (!Thread.currentThread().isInterrupted()) { Message m = new Message(); // m.what = QUESTION_ID; try { if (s == null) s = ss.accept(); BufferedReader input = new BufferedReader( new InputStreamReader(s.getInputStream())); String st = null; st = input.readLine(); String[] temp = parseReadMessage(st); mClientMsg = temp[1]; if(temp.length > 2) { mClientExtraMsg = temp[2]; } m.what = Integer.parseInt(temp[0]); myUpdateHandler.sendMessage(m); } catch (IOException e) { e.printStackTrace(); } } } } } The client code public class ClassAidClient4Activity extends Activity { //telnet localhost 5554 //redir add tcp:5000:6000 private Socket socket; private String serverIpAddress = "192.168.1.102"; private static final int REDIRECTED_SERVERPORT = 5000; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); try { InetAddress serverAddr = InetAddress.getByName(serverIpAddress); socket = new Socket(serverAddr, REDIRECTED_SERVERPORT); } catch (UnknownHostException e1) { mQuestionAdapter.add("UnknownHostException"); e1.printStackTrace(); } catch (IOException e1) { mQuestionAdapter.add("IOException"); e1.printStackTrace(); } } }

  • DllImport Based on OS Platform

    - by Ngu Soon Hui
    I have a mixture of unmanaged code ( backend) and managed code ( front end), as such, I would need to call the unmanaged code from my managed code, using interop techniques and DllImport attribute. Now, I've compiled two versions of unmanaged code, for both 32 and 64 bit OS; they are named service32.dll and service64.dll respectively. So, in my .Net code, I would have to do a DllImport for both dlls: [DllImport(@"service32.dll")] //for 32 bit OS invocation public static void SimpleFunction(); [DllImport(@"service64.dll")] //for 64 bit OS invocation public static void SimpleFunction(); And call them depending on which platform my application is running on. The issue now is that for every unmanaged function, I have to declared it twice, one for 32 bit OS and one for 64 bit OS. This is a duplication of work, and everytime I change the signature of an unmanaged function, I have to modified it in two places. Is there anyway that I can change the argument in DllImport so that the correct dll will be invoked automagically, depending on the platform?

  • Doubt with c# handlers?

    - by aF
    I have this code in c# public void startRecognition(string pName) { presentationName = pName; if (WaveNative.waveInGetNumDevs() > 0) { string grammar = System.Environment.GetEnvironmentVariable("PUBLIC") + "\\SoundLog\\Presentations\\" + presentationName + "\\SpeechRecognition\\soundlog.cfg"; /* if (File.Exists(grammar)) { File.Delete(grammar); } executeCommand();*/ recContext = new SpSharedRecoContextClass(); recContext.CreateGrammar(0, out recGrammar); if (File.Exists(grammar)) { recGrammar.LoadCmdFromFile(grammar, SPLOADOPTIONS.SPLO_STATIC); recGrammar.SetGrammarState(SPGRAMMARSTATE.SPGS_ENABLED); recGrammar.SetRuleIdState(0, SPRULESTATE.SPRS_ACTIVE); } recContext.Recognition += new _ISpeechRecoContextEvents_RecognitionEventHandler(handleRecognition); //recContext.RecognitionForOtherContext += new _ISpeechRecoContextEvents_RecognitionForOtherContextEventHandler(handleRecognition); //System.Windows.Forms.MessageBox.Show("olari"); } } private void handleRecognition(int StreamNumber, object StreamPosition, SpeechLib.SpeechRecognitionType RecognitionType, SpeechLib.ISpeechRecoResult Result) { System.Windows.Forms.MessageBox.Show("entrei"); string temp = Result.PhraseInfo.GetText(0, -1, true); _recognizedText = ""; foreach (string word in recognizedWords) { if (temp.Contains(word)) { _recognizedText = word; } } } public void run() { if (File.Exists(System.Environment.GetEnvironmentVariable("PUBLIC") + "\\SoundLog\\Serialization\\Voices\\identifiedVoicesDLL.txt")) { deserializer = new XmlSerializer(_identifiedVoices.GetType()); FileStream fs = new FileStream(System.Environment.GetEnvironmentVariable("PUBLIC") + "\\SoundLog\\Serialization\\Voices\\identifiedVoicesDLL.txt", FileMode.Open); Object o = deserializer.Deserialize(fs); fs.Close(); _identifiedVoices = (double[])o; } if (File.Exists(System.Environment.GetEnvironmentVariable("PUBLIC") + "\\SoundLog\\Serialization\\Voices\\deletedVoicesDLL.txt")) { deserializer = new XmlSerializer(_deletedVoices.GetType()); FileStream fs = new FileStream(System.Environment.GetEnvironmentVariable("PUBLIC") + "\\SoundLog\\Serialization\\Voices\\deletedVoicesDLL.txt", FileMode.Open); Object o = deserializer.Deserialize(fs); fs.Close(); _deletedVoices = (ArrayList)o; } myTimer.Interval = 5000; myTimer.Tick += new EventHandler(clearData); myTimer.Start(); if (WaveNative.waveInGetNumDevs() > 0) { _waveFormat = new WaveFormat(_samples, 16, 2); _recorder = new WaveInRecorder(-1, _waveFormat, 8192 * 2, 3, new BufferDoneEventHandler(DataArrived)); _scaleHz = (double)_samples / _fftLength; _limit = (int)((double)_limitVoice / _scaleHz); SoundLogDLL.MelFrequencyCepstrumCoefficients.calculateFrequencies(_samples, _fftLength); } } startRecognition is a method for Speech Recognition that load a grammar and makes the recognition handler here: recContext.Recognition += new _ISpeechRecoContextEvents_RecognitionEventHandler(handleRecognition); Now I have a problem, when I call the method startRecognition before method run, both handlers (the recognition one and the handler for the Tick) work well. If a word is recognized, handlerRecognition method is called. But, when I call the method run before the method startRecognition, both methods seem to run well but then the recognition Handler is never executed! Even when I see that words are recognized (because they happear on the Windows Speech Recognition app). What can I do for the recognition handler be allways called?

  • Swing Timer in Conjunction with Possible Long-running Background Task

    - by javacavaj
    I need to perform a task repeatedly that affects both GUI-related and non GUI-related objects. One caveat is that no action should performed if the previous task had not completed when the next timer event is fired. My initial thoughts are to use a SwingTimer in conjunction with a javax.swing.SwingWorker object. The general setup would look like this. class { timer = new Timer(speed, this); timer.start(); public void actionPerformed(ActionEvent e) { SwingWorker worker = new SwingWorker() { @Override public ImageIcon[] doInBackground() { // potential long running task } @Override public void done() { // update GUI on event dispatch thread when complete } } } Some potential issues I see with this approach are: 1) Multiple SwingWorkers will be active if a worker has not completed before the next ActionEvent is fired by the timer. 2) A SwingWorker is only designed to be executed once, so holding a reference to the worker and reusing (is not?) a viable option. Is there a better way to achieve this?

  • Log information inside a JUnit Suite

    - by Alex Marinescu
    I'm currently trying to write inside a log file the total number of failed tests from a JUnite Suite. My testsuite is defined as follows: @RunWith(Suite.class) @SuiteClasses({Class1.class, Class2.class etc.}) public class SimpleTestSuite {} I tried to define a rule which would increase the total number of errors when a test fails, but apparently my rule is never called. @Rule public MethodRule logWatchRule = new TestWatchman() { public void failed(Throwable e, FrameworkMethod method) { errors += 1; } public void succeeded(FrameworkMethod method) { } }; Any ideas on what I should to do to achieve this behaviour?
