  • running jython bytecode using java

    - by noamtm
    It looks like I'm missing something. When using Jython to run my Python code in Java, Java bytecode files are generated (test.py - [email protected]). Can I run these classes directly using java? In other words, I want to make this: $ java test@py [additional cp args] work. The intent: writing Python code and not having to give away source code.

  • Tests that are 2-3 times bigger than the testable code

    - by HeavyWave
    Is it normal to have tests that are way bigger than the actual code being tested? For every line of code I am testing I usually have 2-3 lines in the unit test. Which ultimately leads to tons of time being spent just typing the tests in (mock, mock and mock more). Where are the time savings? Do you ever avoid tests for code that is along the lines of being trivial? Most of my methods are less than 10 lines long and testing each one of them takes a lot of time, to the point where, as you see, I start questioning writing most of the tests in the first place. I am not advocating not unit testing, I like it. Just want to see what factors people consider before writing tests. They come at a cost (in terms of time, hence money), so this cost must be evaluated somehow. How do you estimate the savings created by your unit tests, if ever?

    - by SpikETidE
    Hi Everyone.... I just began looking into source control.... And installed subversion from collabnet... I also use netbeans(6.8) to work with PHP... I have done the following steps I have installed subversion is c:\program files\collabnet\ and the root for the repositories in e:\svn_repository I then created a repository as e:\svn_repository\lemon I then edited the passwd file and added the user and password I then tried importing an existing project into the repository with the address - svn://localhost/lemon with the new user and password. After all this, i get the error "authentication failed"... I am pretty sure the authentication is correct... I tried importing the project with the address file:///E:/sv_repository/lemon with no authentication and it connected... But i got other guys who got to connect to this server through lan and svn:// protocol is the only option.... What am i doing wrong here..? Also.. where can i find a proper tutorial to connect netbeans and collabnet subversion.....? Thanks for your suggestions and time...

    I have developed a custom keypad using resco controls in my application I have currently handled the backspace button click event with the following code private void customKeyboard1_KeyboardKeyUp(object sender, Resco.Controls.Keyboard.KeyPressedEventArgs e) { if (e.Key.Text == "Backspace") { Resco.Controls.Keyboard.CustomKeyboard.SendBackspace(); e.Handled = true; } } This works fine with the edit boxes in the application but not working in edit boxes in the web pages (for eg. on gmail username text box). so is there any way to raise the KeyDown event manually

I am looking to store this text filed inputs when user enters and able retrieve in other tabs. Previously I have set key for different text fields and setobject:withkey task and able to retrive text filed values in same view Controller [[NSUserDefaults standardUserDefaults] stringForKey:key] task. Now I am looking to create database which has different objects and each objects has data values of different Text Field inputs that I can access in whole application. like DatabaseName - Object1 - Name, Username & Password - Object2 - Name, Username & Password Something like structure in Normal C so it would be easy to retrieve data.

  • Why Moq is throwing "expected Invocation on the mock at least once". Where as it is being set once,e

    - by Mohit
    Following is the code. create a class lib add the ref to NUnit framework 2.5.3.9345 and Moq.dll 4.0.0.0 and paste the following code. Try running it on my machine it throws TestCase 'MoqTest.TryClassTest.IsMessageNotNull' failed: Moq.MockException : Expected invocation on the mock at least once, but was never performed: v = v.Model = It.Is(value(Moq.It+<c__DisplayClass21[MoqTest.GenInfo]).match) at Moq.Mock.ThrowVerifyException(IProxyCall expected, Expression expression, Times times, Int32 callCount) at Moq.Mock.VerifyCalls(Interceptor targetInterceptor, MethodCall expected, Expression expression, Times times) at Moq.Mock.VerifySet[T](Mock1 mock, Action1 setterExpression, Times times, String failMessage) at Moq.Mock1.VerifySet(Action`1 setterExpression) Class1.cs(22,0): at MoqTest.TryClassTest.IsMessageNotNull() using System; using System.Collections.Generic; using System.Linq; using System.Text; using Moq; using NUnit.Framework; namespace MoqTest { [TestFixture] public class TryClassTest { [Test] public void IsMessageNotNull() { var mockView = new Mock<IView<GenInfo>>(); mockView.Setup(v => v.ModuleId).Returns(""); TryPresenter tryPresenter = new TryPresenter(mockView.Object); tryPresenter.SetMessage(new object(), new EventArgs()); // mockView.VerifySet(v => v.Message, Times.AtLeastOnce()); mockView.VerifySet(v => v.Model = It.Is<GenInfo>(x => x != null)); } } public class TryPresenter { private IView<GenInfo> view; public TryPresenter(IView<GenInfo> view) { this.view = view; } public void SetMessage(object sender, EventArgs e) { this.view.Model = null; } } public class MyView : IView<GenInfo> { #region Implementation of IView<GenInfo> public string ModuleId { get; set; } public GenInfo Model { get; set; } #endregion } public interface IView<T> { string ModuleId { get; set; } T Model { get; set; } } public class GenInfo { public String Message { get; set; } } } And if you change one line mockView.VerifySet(v => v.Model = It.Is<GenInfo>(x => x != null)); to mockView.VerifySet(v => v.Model, Times.AtLeastOnce()); it works fine. I think Exception is incorrect.

  • Implementing Role based Helpers

    - by Cynics
    So my question is how would you implement your handwritten Helpers based on the role of current user. Would it be efficient to change the behaviour at request time? e.g. the Helper somehow figures out the role of user, and include the proper SubModule? module ApplicationHelper module LoggedInHelper # Some functions end module GuestHelper # The Same functions end # If User is Guest then include GuestHelper # If User is LoggedIn then include LoggedInHelper end Is it efficient this way? is it rails way? I've got a whole bunch of function that act like this, and I don't want to wrap every single one of them in an if statement def menu_actions if current_user.nil? # User is guest { "Log in" => link_to "Login", "/login" } else # User is Logged In { "Log out" => link_to "Logout", "/logout" } end end Thank you for your time and thoughts.

  • Memcache textual protocol cheatsheet ?

    - by Maxim Veksler
    Memcached interface is implemented using a textual protocol. Sometimes it's very useful to be to fetch data stored on your remote server simply by invoking netcat with some shell kung fu, for example: To download the XML result of your nightly data crunching job you might run something like: echo "get 95ec6c7693ec53771c8a3fb1061562b8" | nc localhost 11211 > console_overview_06_04_2010.xml The interesting part here is get SOME_UNIQUE_KEY which is part of the memcached protocol. What other useful usages can you suggest in regard to the ability to interact with memcached using nothing more then command line tools? Thank you, Maxim.

  • Adding a conversion page trough Google Websiteoptimizer API

    - by hoppa
    Hey guys, I'm developing a module which allows users of my cms to create A/B tests from my cms instead of Google's interface. I manage to create tests and add the original page and the alternative page(s) just fine using the API documented here: http://code.google.com/apis/analytics/docs/gwo/ My issue is that i can't find documentation on how to add the conversion page. I tried Google forums but to no avail. Is there anyone here who can help me further? Thanks in advance! [edit] I don't know how badly I'm going against convention at this moment nut is there absolutely no one here who can give me a pointer in the right direction?

  • Storing and comparing biometric information

    - by Chathuranga Chandrasekara
    I am not sure whether this is the best place to post this. But this is strongly related with programming so decided to put this here. In general we use biometrics in computer applications say for authentication. Lets get 2 examples finger prints and facial recognition. In those cases how we keep the information for comparison. As an example we can't keep a image and process it every time. So what are the methodologies we use to store/determine the similarity in such cases? Are there any special algorithms that designed for that purposes.? (Ex : To return a approximately equal value for a finger print of a certain person every time)
