  • Selenium RC throws sessionsid should not be null exception, phpunit 3.4 bug only?

    - by user342775
    I am looking to migrate my selenium RC tests to using PHPUnit 3.4.12 from PHPUnit 3.3.2 The selenium test will fail with an exception of the following when I use assertTextPresent() PHPUnit_Framework_Exception: Response from Selenium RC server for getLocation(). ERROR Server Exception: sessionId should not be null; has this session been started yet?. For example: public function testSending($browser) { ... $browser->click("send"); $browser->waitForPageToLoad("30000"); $browser->assertTextPresent("text"); } Below is the selenium RC log (running on Windows): 15:40:19.676 INFO - Command request: isTextPresent[text, ] on session 153d03a123c42098711994f43c2db34 15:40:19.691 INFO - Got result: OK,false on session 153d023a123c42098711994f43cdb34 15:40:19.879 INFO - Command request: testComplete[, ] on session 153d023a123c4298711994f43c2db34 15:40:19.879 INFO - Killing Firefox... 15:40:20.269 INFO - Got result: OK on session 153d023a123c42098711994f43c2db34 15:40:20.472 INFO - Command request: getLocation[, ] on session null 15:40:20.472 ERROR - Exception running 'getLocation 'command on session null java.lang.NullPointerException: sessionId should not be null; has this session been started yet? As you can see, the test should have completed as indicated by the "Killing Firefox" bit, but it instead continued to do something else and triggered the getLocation[, ] command which caused the exception. I have tried the same test with PHPUnit 3.3.2 which did not produce this problem - the test would happily end without the getLocation(). Any ideas? thanks

  • Python Pre-testing for exceptions when coverage fails

    - by Tal Weiss
    I recently came across a simple but nasty bug. I had a list and I wanted to find the smallest member in it. I used Python's built-in min(). Everything worked great until in some strange scenario the list was empty (due to strange user input I could not have anticipated). My application crashed with a ValueError (BTW - not documented in the official docs). I have very extensive unit tests and I regularly check coverage to avoid surprises like this. I also use Pylint (everything is integrated in PyDev) and I never ignore warnings, yet I failed to catch this bug before my users did. Is there anything I can change in my methodology to avoid these kind of runtime errors? (which would have been caught at compile time in Java / C#?). I'm looking for something more than wrapping my code with a big try-except. What else can I do? How many other build in Python functions are hiding nasty surprises like this???

  • Can I use Data URLs in Android 2.1's Webkit-based browser?

    - by Sven Haiges
    Hi all, I am writing a tutorial about the HTML5 Canvas for mobile and did some basic tests. While I can call the getDataURL() Method on an iPhone's HTML5 Canvas Element, it does not seem to return the data URL on Android 2.1 (Google Nexus One) and it's webkit-based default browser. Here is the sample: var dataURL = canvas.toDataURL(); var img = document.createElement('img'); img.setAttribute('src', dataURL); document.getElementById('box').appendChild(img); This will work on iPhone, it will add a new image element with the same content as the canvas. It does nothing or fails on Android 2.1. Has anyone ever gotten this to work? I am also wondering if anyone could help me with understanding the WebKit Build numbers and what it means with regards to what features I can expect. For the iphone, I see a build number of 528.18, on Android 2.1's Browser I see (from the user agent strign) a WebKit build 530.17. So it looks Android 2.1's webkit browser is more up to date, still some features work on iPhone's webkit but not on Android. Does this comparison just make no sense? Thanx all!

  • Unit test for Web Forms MVP presenter has a null Model

    - by jacksonakj
    I am using Web Forms MVP to write an DotNetNuke user control. When the 'SubmitContactUs' event is raised in my unit test the presenter attempts to set the 'Message' property on the Modal. However the View.Modal is null in the presenter. Shouldn't the Web Forms MVP framework automatically build a new View.Model object in the presenter? It could be that the 'Arrange' portion of my test is missing something that the presenter needs. Any help would be appreciated. Here is my test: using System; using AthleticHost.ContactUs.Core.Presenters; using AthleticHost.ContactUs.Core.Views; using Xunit; using Moq; namespace AthleticHost.ContactUs.Tests { public class ContactUsPresenterTests { [Fact] public void ContactUsPresenter_Sets_Message_OnSubmit() { // Arrange var view = new Mock<IContactUsView>(); var presenter = new ContactUsPresenter(view.Object); // Act view.Raise(v => v.Load += null, new EventArgs()); view.Raise(v => v.SubmitContactUs += null, new SubmitContactUsEventArgs("Chester", "Tester", "[email protected]", "http://www.test.com", "This is a test of the emergancy broadcast system...")); presenter.ReleaseView(); // Assert Assert.Contains("Chester Tester", view.Object.Model.Message); } } }

  • How can I get browser to prompt to save password?

    - by Eric
    Hey, I'm working on a web app that has a login dialog that works like this: User clicks "login" Login form HTML is loaded with AJAX and displayed in DIV on page User enters user/pass in fields and clicks submit. It's NOT a <form> -- user/pass are submitted via AJAX If user/pass are okay, page reloads with user logged in. If user/pass are bad, page does NOT reload but error message appears in DIV and user gets to try again. Here's the problem: the browser never offers the usual "Save this password? Yes / Never / Not Now" prompt that it does for other sites. I tried wrapping the <div> in <form> tags with "autocomplete='on'" but that made no difference. Is it possible to get the browser to offer to store the password without a major rework of my login flow? thanks Eric p.s. to add to my question, I'm definitely working with browers that store passwords, and I've never clicked "never for this site" ...this is a technical issue with the browser not detecting that it's a login form, not operator error :-)

  • .NET regex's not working - 1# check beginning of text entered #2 check structure

    - by Olly
    OK it has unfortunately been a while since I've used REGEX and I am struggling to wonder why its not working with my project. I have used Regex Tester which says my two tests are valid but when it comes to testing in my project they get rejected. 1) Check the text starts with certain characters [RegularExpression("(spAPP)",ErrorMessage = "Stored procedures must begin with spAPP")] This seems to accept spAPP on it's own, but not something like spAPPabcdef which I want it to. I am struggling to find the "Ignore rest of the text" attribute with REGEX. 2) A bit more complicated. I have certain naming conventions for AD groups, so an example would be "UK ROLE IT APPLICATION DEV ADMIN", up to the role name there are standards (so I need the "UK ROLE IT APPLICATION DEV" checked. [RegularExpression(@"((UK|FRANCE|GERMANY|USA)\s(ROLE)\s(IT|NON-IT)\s(APPLICATION)\s(DEV|TEST|LIVE))", ErrorMessage = "Please use AD naming standards.")] I think it might be the fact I am using () around all the words, but its easier to read in my code. The RegexTester I found seems to indicate that it's right, but again, in my .NET project, it rejects it. Thanks,

  • In Ruby, how to implement global behaviour?

    - by Gordon McAllister
    Hi all, I want to implement the concept of a Workspace. This is a global concept - all other code will interact with one instance of this Workspace. The Workspace will be responsible for maintaining the current system state (i.e. interacting with the system model, persisting the system state etc) So what's the best design strategy for my Workspace, bearing in mind this will have to be testable (using RSpec now, but happy to look at alternatives). Having read thru some open source projects out there and I've seen 3 strategies. None of which I can identify as "the best practice". They are: Include the singleton class. But how testable is this? Will the global state of Workspace change between tests? Implemented all behaviour as class methods. Again how do you test this? Implemented all behaviour as module methods. Not sure about this one at all! Which is best? Or is there another way? Thanks, Gordon

  • ARMv6 FIQ, acknowledge interrupt

    - by fastmonkeywheels
    I'm working with an i.mx35 armv6 core processor. I have Interrupt 62 configured as a FIQ with my handler installed and being called. My handler at the moment just toggles an output pin so I can test latency with a scope. With the code below, once I trigger the FIQ it continues forever as fast as it can, apparently not being acknowledged. I'm triggering the FIQ by means of the Interrupt Force Register so I'm assured that the source isn't triggering it this fast. If I disable Interrupt 62 in the AVIC in my FIQ routine the interrupt only triggers once. I have read the sections on the VIC Port in the ARM1136JF-S and ARM1136J-S Technical Reference Manual and it covers proper exit procedure. I'm only having one FIQ handler so I have no need to branch. The line that I don't understand is: STR R0, [R8,#AckFinished] I'm not sure what AckFinished is supposed to be or what this command is supposed to do. My FIQ handler is below: ldr r9, IOMUX_ADDR12 ldr r8, [r9] orr r8, #0x08 @ top LED str r8,[r9] @turn on LED bic r8, #0x08 @ top LED str r8,[r9] @turn off LED subs pc, r14, #4 IOMUX_ADDR12: .word 0xFC2A4000 @remapped IOMUX addr My handler returns just fine and normal system operation resumes if I disable it after the first go, otherwise it triggers constantly and the system appears to hang. Do you think my assumption is right that the core isn't acknowledging the AVIC or could there be another cause of this FIQ triggering?

  • Mocking with Boost::Test

    - by Billy ONeal
    Hello everyone :) I'm using the Boost::Test library for unit testing, and I've in general been hacking up my own mocking solutions that look something like this: //In header for clients struct RealFindFirstFile { static HANDLE FindFirst(LPCWSTR lpFileName, LPWIN32_FIND_DATAW lpFindFileData) { return FindFirstFile(lpFileName, lpFindFileData); }; }; template <typename FirstFile_T = RealFindFirstFile> class DirectoryIterator { //.. Implementation } //In unit tests (cpp) #define THE_ANSWER_TO_LIFE_THE_UNIVERSE_AND_EVERYTHING 42 struct FakeFindFirstFile { static HANDLE FindFirst(LPCWSTR lpFileName, LPWIN32_FIND_DATAW lpFindFileData) { return THE_ANSWER_TO_LIFE_THE_UNIVERSE_AND_EVERYTHING; }; }; BOOST_AUTO_TEST_CASE( MyTest ) { DirectoryIterator<FakeFindFirstFile> LookMaImMocked; //Test } I've grown frustrated with this because it requires that I implement almost everything as a template, and it is a lot of boilerplate code to achieve what I'm looking for. Is there a good method of mocking up code using Boost::Test over my Ad-hoc method? I've seen several people recommend Google Mock, but it requires a lot of ugly hacks if your functions are not virtual, which I would like to avoid. Oh: One last thing. I don't need assertions that a particular piece of code was called. I simply need to be able to inject data that would normally be returned by Windows API functions.

  • What's a good way of building up a String where you specific start and end locations?

    - by Michael Campbell
    (java 1.5) I have a need to build up a String, in pieces. I'm given a set of (sub)strings, each with a start and end point of where they belong in the final string. Was wondering if there were some canonical way of doing this. This isn't homework, and I can use any licensable OSS, such as jakarta commons-lang StringUtils etc. My company has a solution using a CharBuffer, and I'm content to leave it as is (and add some unit tests, of which there are none (?!)) but the code is fairly hideous and I would like something easier to read. As I said this isn't homework, and I don't need a complete solution, just some pointers to libraries or java classes that might give me some insight. The String.Format didn't seem QUITE right... I would have to honor inputs too long and too short, etc. Substrings would be overlaid in the order they appear (in case of overlap). As an example of input, I might have something like: String:start:end FO:0:3 (string shorter than field) BAR:4:5 (String larger than field) BLEH:5:9 (String overlays previous field) I'd want to end up with FO BBLEH 01234567890

  • mocking collection behavior with Moq

    - by Stephen Patten
    Hello, I've read through some of the discussions on the Moq user group and have failed to find an example and have been so far unable to find the scenario that I have. Here is my question and code: // 6 periods var schedule = new List<PaymentPlanPeriod>() { new PaymentPlanPeriod(1000m, args.MinDate.ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(1).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(2).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(3).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(4).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(5).ToString()) }; // Now the proxy is correct with the schedule helper.Setup(h => h.GetPlanPeriods(It.IsAny<String>(), schedule)); Then in my tests I use Periods but the Mocked _PaymentPlanHelper never populates the collection, see below for usage: public IEnumerable<PaymentPlanPeriod> Periods { get { if (CanCalculateExpression()) _PaymentPlanHelper.GetPlanPeriods(this.ToString(), _PaymentSchedule); return _PaymentSchedule; } } Now if I change the mocked object to use another overloaded method of GetPlanPeriods that returns a List like so : var schedule = new List<PaymentPlanPeriod>() { new PaymentPlanPeriod(1000m, args.MinDate.ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(1).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(2).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(3).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(4).ToString()), new PaymentPlanPeriod(1000m, args.MinDate.Value.AddMonths(5).ToString()) }; helper.Setup(h => h.GetPlanPeriods(It.IsAny<String>())).Returns(new List<PaymentPlanPeriod>(schedule)); List<PaymentPlanPeriod> result = new _PaymentPlanHelper.GetPlanPeriods(this.ToString()); This works as expected. Any pointers would be awesome, as long as you don't bash my architecture... :) Thank you, Stephen

  • Rspec stubing view for anonymous controller

    - by Colin G
    I'm trying to test a method on the application controller that will be used as a before filter. To do this I have setup an anonymous controller in my test with the before filter applied to ensure that it functions correctly. The test currently looks like this: describe ApplicationController do controller do before_filter :authenticated def index end end describe "user authenticated" do let(:session_id){"session_id"} let(:user){OpenStruct.new(:email => "[email protected]", :name => "Colin Gemmell")} before do request.cookies[:session_id] = session_id UserSession.stub!(:find).with(session_id).and_return(user) get :index end it { should assign_to(:user){user} } end end And the application controller is like this: class ApplicationController < ActionController::Base protect_from_forgery def authenticated @user = nil end end My problem is when ever I run the test I'm getting the following error 1) ApplicationController user authenticated Failure/Error: get :index ActionView::MissingTemplate: Missing template stub_resources/index with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml, :haml], :formats=>[:html], :locale=>[:en, :en]} in view paths "#<RSpec::Rails::ViewRendering::PathSetDelegatorResolver:0x984f310>" According to the docs the view is not rendered when running controller tests however this points to no stub existing for this action (which is understandable as the view doesn't exist) Anyone have a clue how to solve this problem or stub the view out.

  • Hibernate fails with NullPointerException in EntityTuplizerFactory.constructTuplizer? Why?

    - by Subtwo
    I have a problem when I try to instantiate Hibernate and connect with a MySQL database (see error message below). Curiously enough the connection works fine using the exact same hibernate.cfg.xml file when running Junit tests but it refuses to work when run from Tomcat... I am starting to run out of ideas.

  • Using Moq callbacks correctly according to AAA

    - by Hadi Eskandari
    I've created a unit test that tests interactions on my ViewModel class in a Silverlight application. To be able to do this test, I'm mocking the service interface, injected to the ViewModel. I'm using Moq framework to do the mocking. to be able to verify bounded object in the ViewModel is converted properly, I've used a callback: [Test] public void SaveProposal_Will_Map_Proposal_To_WebService_Parameter() { var vm = CreateNewCampaignViewModel(); var proposal = CreateNewProposal(1, "New Proposal"); Services.Setup(x => x.SaveProposalAsync(It.IsAny<saveProposalParam>())).Callback((saveProposalParam p) => { Assert.That(p.plainProposal, Is.Not.Null); Assert.That(p.plainProposal.POrderItem.orderItemId, Is.EqualTo(1)); Assert.That(p.plainProposal.POrderItem.orderName, Is.EqualTo("New Proposal")); }); proposal.State = ObjectStates.Added; vm.CurrentProposal = proposal; vm.Save(); } It is working fine, but if you've noticed, using this mechanism the Assert and Act part of the unit test have switched their parts (Assert comes before Acting). Is there a better way to do this, while preserving correct AAA order?

  • When can a == b be false and a.Equals(b) true?

    - by alastairs
    I ran into this situation today. I have an object which I'm testing for equality; the Create() method returns a subclass implementation of MyObject. MyObject a = MyObject.Create(); MyObject b = MyObject.Create(); a == b; // is false a.Equals(b); // is true Note I have also over-ridden Equals() in the subclass implementation, which does a very basic check to see whether or not the passed-in object is null and is of the subclass's type. If both those conditions are met, the objects are deemed to be equal. The other slightly odd thing is that my unit test suite does some tests similar to Assert.AreEqual(MyObject.Create(), MyObject.Create()); // Green bar and the expected result is observed. Therefore I guess that NUnit uses a.Equals(b) under the covers, rather than a == b as I had assumed. Side note: I program in a mixture of .NET and Java, so I might be mixing up my expectations/assumptions here. I thought, however, that a == b worked more consistently in .NET than it did in Java where you often have to use equals() to test equality.

  • How do I get my ActivityUnitTestCases to sync with the MessageQueue thread and call my Handler?

    - by Ricardo Gladwell
    I'm writing unit tests for a ListActivity in Android that uses a handler to update a ListAdapter. While my activity works in the Android emulator, running the same code in a unit test doesn't update my adapter: calls to sendEmptyMessage do not call handleMessage in my activity's Handler. How do I get my ActivityUnitTestCase to sync with the MessageQueue thread and call my Handler? The code for the Activity is somewhat like this: public class SampleActivity extends ListActivity implements SampleListener { List samples = new ArrayList(); public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.sample_list); listView.setEmptyView(findViewById(R.id.empty)); } private final Handler handler = new Handler() { @Override public void handleMessage(Message msg) { // unit test never reaches here sharesAdapter = new SampleAdapter(SampleActivity.this, samples); setListAdapter(sharesAdapter); } }; public void handleSampleUpdate(SampleEvent event) { samples.add(event.getSample()); handler.sendEmptyMessage(0); } } The code for my unit test is somewhat like this: public class SampleActivityTest extends ActivityUnitTestCase<SampleActivity> { public SampleActivityTest() { super(SampleActivity.class); } @MediumTest public void test() throws Exception { final SampleActivity activity = startActivity(new Intent(Intent.ACTION_MAIN), null, null); final ListView listView = (ListView) activity.findViewById(android.R.id.list); activity.handleSampleUpdate(new SampleEvent(this)); // unit test assert fails on this line: assertTrue(listView.getCount() == 1); } }

  • Is it practical to program with your feet?

    - by bmm
    Has anyone tried using foot pedals in addition to the traditional keyboard and mouse combo to improve your effectiveness in the editor? Any actual experiences out there? Does it work, or is it just for carpal tunnel relief? I found one blog entry from a programmer who actually tried it: So now I can type using my feet for most of the modifier keys. I am using the pedals as I type this. I am still getting used to them, but the burning in my left wrist has definitely reduced. I think I can also type a little faster, but I am too lazy to do the speed tests with and without the pedals to verify this. On the negative side: Working out where to put your feet when you aren’t typing can be a little awkward. The pedals tend to move around the carpet, despite being metal and quite heavy. Some small spikes might have helped. Although the travel on the pedals is small, they are surprisingly stiff. Another programmer's experience: Anybody with hand pain must get foot pedals, since they can remove a tremendous load from your hands. I have two foot pedals, and use one for the SHIFT key, and the other for the CONTROL key. (I still type META by hand.) I have found that in the process of using the Emacs text editor to compose computer programs, I tend to use the SHIFT, CONTROL and META keys constantly, and it is easy to remove most of this load from one's hands.

  • Optimizing PHP require_once's for low disk i/o?

    - by buggedcom
    Q1) I'm designing a CMS (-who isn't!) but priority is being given to caching. Literally everything is cached. DB rows, DB id queries, Configuration data, processed data, compiled templates. Currently it has two layers of caching. The first is a opcode cache or memory cache such as apc, eaccelerator, xcache or memcached. If an entry is not found in there it is then searched for in the secondary slow cache, ie php includes. Are the opcode caches actually faster than doing a require_once to a php file with a var_export'd array of data in it? My tests are inconclusive as my development box (5.3 of XAMPP) keeps throwing errors installing any of the aforementioned programs. Q2) The CMS has numerous helper classes that are autoloaded on demand instead of loading all files. Mostly each has a require before it so no autoloading needs to take place, however this is not the question. Because a page script can have up to 50/60 helper files included I have a feeling that if the site was under pressure it would buckle because of all the i/o that this incurs. Ignore for the moment that there is output cache in place that would remove the need for what I am about to suggest, and also that opcode caches would render this moot. What I have tried to do is join all the helper files required for the scripts execution in one single file. This is achievable and works well, however it has a side effect of greatly increasing the memory usage dramatically even though technically the same code is being used. What are your thoughts and opinions on this?

  • Why does trying to unit test with two .NET 4.0 assemblies under NUnit 2.5.4 fail?

    - by GiddyUpHorsey
    I have an MSBuild script that uses NUnit to run tests in two assemblies. These were on .NET Framework 3.5 and it worked perfectly for a long time. The command line was: (actual paths & names simplified) nunit-console tests1\bin\debug\tests1.dll tests2\bin\tests2.dll I've upgraded to VS2010 and have now made the two test assemblies target .NET 4.0. I've also upgraded to NUnit 2.5.4. I can unit test a single assembly with the following: nunit-console tests1\bin\debug\tests1.dll /framework=4.0.30319 It works fine with either tests1.dll or tests2.dll. If I try to specify both like before, it now fails. nunit-console tests1\bin\debug\tests1.dll tests2\bin\debug\tests2.dll /framework=4.0.30319 The error is: Could not load file or assembly 'tests2' or one of its dependencies. The system cannot find the file specified. I've had a look in fuslogvw and it shows tests2 being searched for in the tests1\bin\debug and nunit-console folders. It never searches tests2\bin\debug even though it's specified on the command line. What's up with that?

  • video streaming infrastructure

    - by alchemical
    We would like to set-up a live video-chat web site and are looking for basic architectural advice and/or a recomendation for a particular framework to use. Here are the basic features of the site: Most streams will be broadcast live from a single person with a web cam, etc., and viewed by typically 1-10 people, although there could be up to 100+ viewers on the high side. Audio and video do not have to be super-high quality, but do need to be "good enough". The main point is to convey the basic info in the video (and audio). If occasionally the frame-rate drops low and then goes back to normal fairly soon, we could live with that. Budget is an issue, so we are in general looking for a lower cost solution that will give us most of what we need in temers of performance and quality. We are looking at Peer1 for co-lo. The rest of our web site will be .Net / Windows platform. We are open to looking at any platform for the best streaming solution, although our technical expertise is currently more on the Windows side.

    Hi All, I am trying to create some line charts from a dataset and getting an error (WPF+WPF Toolkit + C#): Nullable object must have a value Here is a code that I use to add some data points to the chart: ObservableCollection points = new ObservableCollection(); foreach (DataRow dr in dc.Tables[0].Rows) { points.Add(new VelChartPoint() { Label = dr[0].ToString(), Value = double.Parse(dr[1].ToString()) }); } Here is a class VelChartPoint public class VelChartPoint : VelObject, INotifyPropertyChanged { public DateTime Date { get; set; } public string Label { get; set; } private double _Value; public double Value { get { return _Value; } set { _Value = value; var handler = PropertyChanged; if (null != handler) { handler.Invoke(this, new PropertyChangedEventArgs("Value")); } } } public string FieldName { get; set; } public event PropertyChangedEventHandler PropertyChanged; public VelChartPoint() { } } So the problem occures in this part of the code points.Add(new VelChartPoint { Name = dc.Tables[0].Rows[0][0].ToString(), Value = double.Parse(dc.Tables[0].Rows[0][1].ToString()) } ); I've made some tests, here are some results i've found out. This part of code does'nt work for me: string[] labels = new string[] { "label1", "label2", "label3" }; foreach (string label in labels) { points.Add(new VelChartPoint { Name = label, Value = 500.0 } ); } But this one works fine: points.Add(new VelChartPoint { Name = "LabelText", Value = double.Parse(dc.Tables[0].Rows[0][1].ToString()) } ); Please, help me to solve this error.

  • GWT, MVP, and UIBinding - How to get the best of all worlds

    - by Stephane Grenier
    With MVP, you normally bind the View (UI) with the Presenter in the Presenter. However with the latest version of GWT, especially with UIBinding, you can do the following in the View: @UiHandler("loginButton") void onAboutClicked(ClickEvent event) { // my login code } Which basically exchanges a lot of anonymous inner class code for some quick annotation code. Very nice!! The problem is that this code is in the view and not the presenter... So I thought maybe: @UiHandler("loginButton") void onAboutClicked(ClickEvent event) { myPresenter.onAboutClicked(...); } But there are several problems with this approach. The most important, you blur the lines between View and Presenter. Who does which binding, in some cases it's the View, in others it's the presenter (binding to events not in your current view but that need to be attached - for example a system wide update event). You still get the benefit of being able to unit test your presenter, but at what cost. The responsibilities are messy now. For example the binding is sometimes in the View and others times in the Presenter level. I can see the code falling into all kinds of chaos with time. I also thought of extending the Presenter to the View, so that you could do this in the View. The problem here is that you lose the Presenter's ability to run standard unit tests! That's a major issue. That and the lines again become blurred. So my question, does anyone have a good method of taking advantage of the annotation from UIBinding within the MVP pattern without blurring the lines and losing the advantages of the MVP pattern?

  • Is There a Time at which to ignore IDisposable.Dispose?

    - by Mystagogue
    Certainly we should call Dipose() on IDisposable objects as soon as we don't need them (which is often merely the scope of a "using" statement). If we don't take that precaution then bad things, from subtle to show-stopping, might happen. But what about "the last moment" before process termination? If your IDisposables have not been explicitly disposed by that point in time, isn't it true that it no longer matters? I ask because unmanaged resources, beneath the CLR, are represented by kernel objects - and the win32 process termination will free all unmanaged resources / kernel objects anyway. Said differently, no resources will remain "leaked" after the process terminates (regardless if Dispose() was called on lingering IDisposables). Can anyone think of a case where process termination would still leave a leaked resource, simply because Dispose() was not explicitly called on one or more IDisposables? Please do not misunderstand this question: I am not trying to justify ignoring IDisposables. The question is just technical-theoretical. EDIT: And what about mono running on Linux? Is process termination there just as "reliable" at cleaning up unmanaged "leaks?"

  • ASP.NET MVC2 DataAnnotations not catching error

    - by Paul Connolly
    Can somebody help me to figure out why DataAnnotations will not work with my MVC2 project in VS 2008 SP1? Here's the situation.. I uninstalled VS2008 and MVC1, then reinstalled VS2008 SP1 and .NET 3.5 SP1 and MVC2. Now when I create a clean project as soon as it has to hit the DataAnnotations Dll (e.g. say when I go to Register.aspx it fails at the first "LabelFor" that it encounters. I can overcome this by changing the "Copy Local" property of the dll to True but this then creates a conflict with the same dll in the Tests project. If then I delete the test project and try agan, it runs but does not catch any validation failures. I have gone right back to basics and followed the step by step ScottGu Datavalidation tutorial at : http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx And at the "Et viola" bit where we usually go "Whoa! cool!" I say "It never caught!". Any Ideas?
