  • Testing local scoped object with mockito without refactoring

    - by supertonsky
    Say I have the following code: public class ClassToTest { AnotherClass anotherClass; public void methodToTest( int x, int y ) { int z = x + y anotherClass.receiveSomething( z ); } } public class AnotherClass { public void receiveSomething( int z ) {.. do something.. } } I want to make assertion on the value of the variable z. How do I do this? Variables x, y, and z could be some other Java class types, and I just used "int" for simplicity.

  • Is it good practise to blank out inherited functionality that will not be used?

    - by Timo Kosig
    I'm wondering if I should change the software architecture of one of my projects. I'm developing software for a project where two sides (in fact a host and a device) use shared code. That helps because shared data, e.g. enums can be stored in one central place. I'm working with what we call a "channel" to transfer data between device and host. Each channel has to be implemented on device and host side. We have different kinds of channels, ordinary ones and special channels which transfer measurement data. My current solution has the shared code in an abstract base class. From there on code is split between the two sides. As it has turned out there are a few cases when we would have shared code but we can't share it, we have to implement it on each side. The principle of DRY (don't repeat yourself) says that you shouldn't have code twice. My thought was now to concatenate the functionality of e.g. the abstract measurement channel on the device side and the host side in an abstract class with shared code. That means though that once we create an actual class for either the device or the host side for that channel we have to hide the functionality that is used by the other side. Is this an acceptable thing to do: public abstract class MeasurementChannelAbstract { protected void MethodUsedByDeviceSide() { } protected void MethodUsedByHostSide() { } } public class DeviceMeasurementChannel : MeasurementChannelAbstract { public new void MethodUsedByDeviceSide() { base.MethodUsedByDeviceSide(); } } Now, DeviceMeasurementChannel is only using the functionality for the device side from MeasurementChannelAbstract. By declaring all methods/members of MeasurementChannelAbstract protected you have to use the new keyword to enable that functionality to be accessed from the outside. Is that acceptable or are there any pitfalls, caveats, etc. that could arise later when using the code?

  • conditionally enabling constructor

    - by MK
    Here is how I can conditionally enable a constructor of a class : struct Foo { template<class T> Foo( T* ptr, boost::enable_if<is_arithmetic<T> >::type* = NULL ) {} }; I would like to know why I need to do the enabling via a dummy parameter. Why can I not just write : struct Foo { template<class T> Foo( boost::enable_if<is_arithmetic<T>, T>::type* = NULL ) {} };

  • Ruby Metaprogramming

    - by Veerendra Manikonda
    I am having a method which returns the price of a given symbol and i am writing a test for that method. This is my test def setup @asset = NetAssetValue.new end def test_retrieve_price_for_symbol_YHOO assert_equal(33.987, @asset.retrieve_price_for_a_symbol('YHOO')) end def test_retrive_price_for_YHOO def self.retrieve_price_for_a_symbol(symbol) 33.77 end assert_equal(33.97, @asset.retrieve_price_for_a_symbol('YHOO')) end This is my method. def retrieve_price_for_a_symbol(symbol) symbol_price = { "YHOO" => 33.987, "UPS" => 35.345, "T" => 80.90 } raise Exception if(symbol_price[symbol].nil?) symbol_price[symbol] end I am trying to mock the retrieve_price_for_a_symbol method by writing same method in test class but when i call it, the call is happening to method in main class not in the test class. How do I add that method to meta class from test and how do i call it? Please help.

  • Easiest way to submit data via PHP?

    - by Abijah
    I'm new to PHP, and have spent 10 hours trying to figure this problem out. The goal is to take all data entered into this order form, and send it to my email via PHP. I have 2 questions: 1. I can get PHP to send data from a single menu item (example: Mexican Tortas), but how do I get PHP to send data from multiple items (example: Mexican Tortas, Fish Sandwich and Hamburger)? 2. How do I tell PHP to not send data from menu items that don't have the "How Many?" or "Customize It?" text fields filled out? If you could provide a super simple example (or a link to a learning resource) I would really appreciate it. Thank you, Abijah PHP <?php if(isset($_POST['submit'])) { $to = "[email protected]"; $subject = "New Order"; $name_field = $_POST['name']; $phone_field = $_POST['phone']; $item = $_POST['item']; $quantity = $_POST['quantity']; $customize = $_POST['customize']; } $body = "Name: $name_field\nPhone: $phone_field\n\nItem: $item\nQuantity: $quantity\nCustomize: $customize"; echo "Data has been submitted to $to!"; mail($to, $subject, $body); ?> HTML <form action="neworder.php" method="POST"> <div class ="item"> <img style="float:left; margin-right:15px; border:1px Solid #000; width:200px; height:155px;" src="images/mexicantortas.jpg"> <h1>Mexican Torta - $8.50</h1> <input name="item" type="hidden" value="Mexican Torta"/> <h2>How Many? <font color="#999999">Ex: 1, 2, 3...?</font></h2> <input name="quantity" type="text"/> <h3>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></h3> <textarea name="customize"/></textarea> </div><!-- ITEM_LEFT --> <div class ="item"> <img style="float:left; margin-right:15px; border:1px Solid #000; width:200px; height:155px;" src="images/fishsandwich.jpg"> <h1>Fish Sandwich - $8.50</h1> <input name="item" type="hidden" value="Fish Sandwich"/> <h2>How Many? <font color="#999999">Ex: 1, 2, 3...?</font></h2> <input name="quantity" type="text"/> <h3>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></h3> <textarea name="customize"/></textarea> </div><!-- ITEM_LEFT --> <div class ="item"> <img style="float:left; margin-right:15px; border:1px Solid #000; width:200px; height:155px;" src="images/hamburgers.jpg"> <h1>Hamburger w/ Fries - $7.00</h1> <input name="item" type="hidden" value="Fish Sandwich"/> <h2>How Many? <font color="#999999">Ex: 1, 2, 3...?</font></h2> <input name="quantity" type="text"/> <h3>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></h3> <textarea name="customize"/></textarea> </div><!-- ITEM_LEFT --> <div class="horizontal_form"> <div class="form"> <h2>Place Your Order Now: <font size="3"><font color="#037B41">Fill in the form below, and we'll call you when your food is ready to be picked up...</font></font></h2> <p class="name"> <input type="text" name="name" id="name" style="text-align:center;" onClick="this.value='';" value="Enter your name"/> </p> <p class="phone"> <input type="text" name="phone" id="phone" style="text-align:center;" onClick="this.value='';" value="Enter your phone #"/> </p> <p class="submit"> <input type="submit" value="Place Order" name="submit"/> </p> </div><!-- FORM --> </div><!-- HORIZONTAL_FORM --> </form>

  • How to test Guice Singleton?

    - by 01
    Guice Singletons are weird for me First I thought that IService ser = Guice.createInjector().getInstance(IService.class); System.out.println("ser=" + ser); ser = Guice.createInjector().getInstance(IService.class); System.out.println("ser=" + ser); will work as singleton, but it returns ser=Service2@1975b59 ser=Service2@1f934ad its ok, it doesnt have to be easy. Injector injector = Guice.createInjector(); IService ser = injector.getInstance(IService.class); System.out.println("ser=" + ser); ser = injector.getInstance(IService.class); System.out.println("ser=" + ser); works as singleton ser=Service2@1975b59 ser=Service2@1975b59 So i need to have static field with Injector(Singleton for Singletons) how do i pass to it Module for testing?

  • Parse xml file with same tag multiple times iphone sdk

    - by neha
    Hi all, In my application, I have a tag multiple times. I'm using xml parser. I'm taking a corresponding element with similar name as the one in xml file in my class. So in case of: <photo>abc</photo> <photo>def</photo> What I get in photo element of my class is the second element i.e def, as the first one gets overwritten as there's only one photo element in my class. My question is am I wrong in taking similar elements in class as in case of xml? Is there any better method or a better parser? Or I'm on right path and have to do this manually by setting some flags etc? Thanx in advance.

  • Do I always need to rebuild the project containing references to sub project's dll, if sub projects

    - by Puneet Dudeja
    I have a solution containing 4 class library projects and one "web site" project. The web site project contains references to the 3 class library projects, whenever I make changes in any of the class library projects, the only option I see is to rebuild the web site which takes a lot of time. Is there any option that I can only update the dll references and the changes are reflected in the web site project ?

  • MVC + Repository Pattern - Still depends on Data Model?

    - by Jack
    I've started a project for school in which I am using ASP.NET MVC 2 + LINQ2SQL, and a business layer so my UI doesnt interact with the DB directly. My question is this: In my MVC project, when bringing up views and passing around data, I still have to include my Data project for access to the classes in my Linq2Sql project. Is this correct? Example: Controller: ClassesRepository cr = new ClassesRepository(); // this is from my Business project Class classToEdit = cr.GetByClassId(id); // "Class" is from my data project I still have to reference the Class class in my linq2sql data project - shouldn't my UI be completely independent of my data layer? Or maybe I'm going about this all wrong.

  • Serializing an extended form object

    - by andyperfect
    I've been reading up on this whole subject, but I never came across this specific problem. I already understand that the whole idea of serializing an entire form is a horrible idea and just doesn't work. But, I am encountering a bit of a different problem. I have a class that inherits the "button" form object, that I call DataButton. Now for my problem. I want to be able to serialize this class, but I don't need any of the information from the actual button class. Is there any way to bypass the fact that I can't set the button form object to Serializable() and notify VB that when serialization is to occur, it should simply skip over that information? Theoretically, if such a procedure were possible, I'd be able to do the entire serialization without a hitch. I came up with the idea earlier of removing the "inherits" feature from the class, and having simply a button within the class, but that makes my program really difficult to work with as I am constantly changing the location, size, backgroundImage, text, and whatnot. Thus, immediate updates would be much tougher to work with. Any help would be greatly appreciated.

  • How to save to two tables using one SQLAlchemy model

    - by Oatman
    I have an SQLAlchemy ORM class, linked to MySQL, which works great at saving the data I need down to the underlying table. However, I would like to also save the identical data to a second archive table. Here's some psudocode to try and explain what I mean my_data = Data() #An ORM Class my_data.name = "foo" #This saves just to the 'data' table session.add(my_data) #This will save it to the identical 'backup_data' table my_data_archive = my_data my_data_archive.__tablename__ = 'backup_data' session.add(my_data_archive) #And commits them both session.commit() Just a heads up, I am not interested in mapping a class to a JOIN, as in: http://www.sqlalchemy.org/docs/05/mappers.html#mapping-a-class-against-multiple-tables

  • connecting to multiple resources

    - by Dudu
    I would like to know if there is a way to connect to multiple resources: Specifically I have the following problem abstact class BaseClass { ObservableCollection<BaseClass>; } class GrandSonClass:BaseClass{} class SonClass:BaseClass{} class FatherClass:BaseClass { CollectionViewSource col = new CollectionViewSource ; col.Source = Items.SelectMany(p => p.Items); } FatherClass's Items are of ChildrenClass type, and ChildrenClass's Items are of GrandSonClass type; I want FatherClass to bind to all the GrandSonClass's items it possesses. The solution of using SelectMany is not good as I need this to be dynamically updated whenever FatherClass adds more Items and whenever its Items(SonClasses) add more Items. Now I could go on and write notifiaction events but I was wondering if there is a smarter way to do it -i.e. simply define the sources as the Items of each Item FatherClass posses

  • is it safe to refactor my django models?

    - by Johnd
    My model is similar to this. Is this ok or should I make the common base class abstract? What are the differcenes between this or makeing it abstract and not having an extra table? It seems odd that there is only one primary key now that I have factored stuff out. class Input(models.Model): details = models.CharField(max_length=1000) user = models.ForeignKey(User) pub_date = models.DateTimeField('date published') rating = models.IntegerField() def __unicode__(self): return self.details class Case(Input): title = models.CharField(max_length=200) views = models.IntegerField() class Argument(Input): case = models.ForeignKey(Case) side = models.BooleanField() is this ok to factor stuff out intpu Input? I noticed Cases and Arguments share a primary Key. like this: CREATE TABLE "cases_input" ( "id" integer NOT NULL PRIMARY KEY, "details" varchar(1000) NOT NULL, "user_id" integer NOT NULL REFERENCES "auth_user" ("id"), "pub_date" datetime NOT NULL, "rating" integer NOT NULL ) ; CREATE TABLE "cases_case" ( "input_ptr_id" integer NOT NULL PRIMARY KEY REFERENCES "cases_input" ("id"), "title" varchar(200) NOT NULL, "views" integer NOT NULL ) ; CREATE TABLE "cases_argument" ( "input_ptr_id" integer NOT NULL PRIMARY KEY REFERENCES "cases_input" ("id"), "case_id" integer NOT NULL REFERENCES "cases_case" ("input_ptr_id"), "side" bool NOT NULL )

  • Spring MVC managing multiple views with single controller

    - by Sudhir
    I am trying to implement order management module. There are different order types (approximately about 15). Each order has a seperate view. But the actions performed on UI are same irrespective of order type. Below is the structure of my DTO abstract class Order abstract class SecurityOrder extends Order abstract class TermDepositOrder extends Order ..... ..... ..... I am trying to implement a single controller capable of managing all views. Something similar to the one below: @Controller public class OrderController<F extends Order> { public F validate(F order) { } public F insert(F order) { } } I am not sure how spring mvc would be able to map request parameters properly to the order instance as it doesn't know which order instance to populate. Is it possible to achieve this with single controller or should I go with a controller for each order type and duplicate same code across all controllers?

  • jquery: .attr() fails for child element

    I'm going crazy staring at this. I need to change the attribute of an element, something which I have done many times before. But it fails. Now I can't even get jquery to show me the attribute that it has. Does it have to do with what is returned by find()? var c = new_photo_div.find('[class = photo]')[0]; alert(c); alert(new_photo_div.attr('class')); alert(c.attr('class')); The first alert correctly identifies the element: Object HTMLImageElement The second alert correctly gives me the class of new_photo_div. The third alert fails. No alert. I think it should say: photo

  • jQuery 1.5.1 vs 1.4.4 weirdness

    - by zobgib
    I have been getting some weird errors when I upgrade jQuery from 1.4.4 to 1.5.1. Maybe you guys can explain what I need to change or why the new version is not working. In 1.4.4 I have the following code <div class="navlink home" data-link="home"> <span class="top">Home</span> </div> <div id="index-03"> </div> <div class="navlink resume" data-link="resume"> <span class="top">Resume</span> </div> <div id="index-05"> </div> <div id="index-06"> </div> <div class="navlink portfolio" data-link="portfolio"> <span class="bottom">Portfolio</span> </div> JS: $(".navlink").hover( function () { $(this).delay(100).animate({backgroundPosition: "-100% 0"}, 400); $(this).find("span").css("textDecoration","underline"); }, function () { $(this).queue("fx", []); $(this).animate({backgroundPosition: "0% 0%"}, 400); $(this).find("span").css("textDecoration","none"); } ); Which works just fine. but when I switch jQuery versions by changing this line in my header from <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script> to <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script> The above code quits animating and the background image just disappears. Here is a jsFiddle that shows what's happening just change the jQuery version on the side between 1.4.4 and 1.5.1 http://jsfiddle.net/fUXZ4/ -- 1.4.4 http://jsfiddle.net/3APCd/ -- 1.5.1 Here is a video of exactly what is happening to me: http://img.zobgib.com/2011-03-07_1905.swf

  • Why does the VS2005 debugger not report "base." values properly? (was "Why is this if statement fail

    - by Rawling
    I'm working on an existing class that is two steps derived from System.Windows.Forms.Combo box. The class overrides the Text property thus: public override string Text { get { return this.AccessibilityObject.Value; } set { if (base.Text != value) { base.Text = value; } } } The reason given for that "get" is this MS bug: http://support.microsoft.com/kb/814346 However, I'm more interested in the fact that the "if" doesn't work. There are times where "base.Text != value" is true and yet pressing F10 steps straight to the closing } of the "set" and the Text property is not changed. I've seen this both by just checking values in the debugger, and putting a conditional breakpoint on that only breaks when the "if" statement's predicate is true. How on earth can "if" go wrong? The class between this and ComboBox doesn't touch the Text property. The bug above shouldn't really be affecting anything - it says it's fixed in VS2005. Is the debugger showing different values than the program itself sees? Update I think I've found what is happening here. The debugger is reporting value incorrectly (including evaluating conditional breakpoints incorrectly). To see this, try the following pair of classes: class MyBase { virtual public string Text { get { return "BaseText"; } } } class MyDerived : MyBase { public override string Text { get { string test = base.Text; return "DerivedText"; } } } Put a breakpoint on the last return statement, then run the code and access that property. In my VS2005, hovering over base.Text gives the value "DerivedText", but the variable test has been correctly set to "BaseText". So, new question: why does the debugger not handle base properly, and how can I get it to?

  • Where do you put non-controller classes in codeigniter?

    - by sprugman
    I've got a class Widgets. Widgets are made up of Doohickies. I'm never going to need to access Doohickies directly via url -- they're essentially a private class, only used by Widgets. Where do you put your code to define the Doohicky class? In /app/controllers/doohicky.php? in app/controllers/widget.php? somewhere else? Obviously, the former seems cleaner, but it's not obvious to me how to make the Doohicky class available to Widget.
