  • Is it possible to use the ScalaTest BDD syntax in a JUnit environment?

    - by ebruchez
    I would like to describe tests in BDD style e.g. with FlatSpec but keep JUnit as a test runner. The ScalaTest Quick Start does not seem to show any example of this: http://www.scalatest.org/getting_started_with_junit_4 I first tried naively to write tests within @Test methods, but that doesn't work and the assertion is never tested: @Test def foobarBDDStyle { "The first name control" must "be valid" in { assert(isValid("name·1")) } // etc. } Is there any way to achieve this? It would be even better if regular tests can be mixed and matched with BDD-style tests.

  • Interview question: difference between object and object-oriented languages.

    - by Bar
    My friend was asked the following question: what's the difference between object language and object-oriented language? It's a little unintelligible question. What does term «object language» correspond to? Does that mean «pure» object-oriented language, like the Wikipedia article says: Languages called "pure" OO languages, because everything in them is treated consistently as an object, from primitives such as characters and punctuation, all the way up to whole classes, prototypes, blocks, modules, etc. They were designed specifically to facilitate, even enforce, OO methods. Examples: Smalltalk, Eiffel, Ruby, JADE, VB.NET.

  • Pass parameters to a user control - asp.net

    - by Cristian Boariu
    Hi, I have this user control: <user:RatingStars runat="server" product="<%= getProductId() %>" category="<%= getCategoryId() %>"></user:RatingStars> You see that i fill the product and category by calling two methods: public string getProductId() { return productId.ToString(); } public string getCategoryId() { return categoryId.ToString(); } I do not understand why, in the user control, when i take the data received (product and category) it gives me "<%= getProductId() %" instead of giving the id received from that method... Any help would be kindly appreciated...

  • Hibernate pluralization

    - by matiasf
    I have A MySQL database currently in production use for a CakePHP application A Java SE application accessing the same database via Hibernate, currently in development. I'm using the Netbeans "automigrate" feature to create the POJO classes and XML files (do I really need the XML files when using annotations?). As the schema is quite complex creating the tables manually is way too much work. Cake expects all DB tables to be pluralized (the Address class is automagically mapped to the addresses table). When running the Netbeans automigration it then does pluralization on the already pluralized table names (I'm getting Addresses.java and setAddresseses() methods). I know I'm asking for trouble running two very different data layers against the same database, but I'd like to know if it's possible to have Netbeans generating the POJO classes in singular form or if there is another (better) way to manage this.

  • Using jQuery, how to modify text outside of tags?

    - by Jacob
    Given a string of text that is both adjacent to a span and inside of a div, what are some methods to modify just that text, leaving the surrounding HTML intact? For example: <div id="my-div">modify this text<span id="my-span"></span></div> I have tried things like $('#my-div').html(function(i, elem){blah;}); but this seems to cause the span to be deleted and a new span to be added, because some styling is lost. I realize that it would be best to wrap the text string in its own HTML tags before applying client-side code, but that is out of my control.

  • How to select the most recent set of dated records from a mysql table

    - by Ken
    I am storing the response to various rpc calls in a mysql table with the following fields: Table: rpc_responses timestamp (date) method (varchar) id (varchar) response (mediumtext) PRIMARY KEY(timestamp,method,id) What is the best method of selecting the most recent responses for all existing combinations of method and id? For each date there can only be one response for a given method/id. Not all call combinations are necessarily present for a given date. There are dozens of methods, thousands of ids and at least 356 different dates Sample data: timestamp method id response 2009-01-10 getThud 16 "....." 2009-01-10 getFoo 12 "....." 2009-01-10 getBar 12 "....." 2009-01-11 getFoo 12 "....." 2009-01-11 getBar 16 "....." Desired result: 2009-01-10 getThud 16 "....." 2009-01-10 getBar 12 "....." 2009-01-11 getFoo 12 "....." 2009-01-11 getBar 16 "....." (I don't think this is the same question - it won't give me the most recent response)

  • Python unittest with expensive setup

    - by Staale
    My test file is basically: class Test(unittest.TestCase): def testOk(): pass if __name__ == "__main__": expensiveSetup() try: unittest.main() finally: cleanUp() However, I do wish to run my test through Netbeans testing tools, and to do that I need unittests that don't rely on an environment setup done in main. Looking at http://stackoverflow.com/questions/402483/caching-result-of-setup-using-python-unittest - it recommends using Nose. However, I don't think Netbeans supports this. I didn't find any information indicating that it does. Additionally, I am the only one here actually writing tests, so I don't want to introduce additional dependencies for the other 2 developers unless they are needed. How can I do the setup and cleanup once for all the tests in my TestSuite? The expensive setup here is creating some files with dummy data, as well as setting up and tearing down a simple xml-rpc server. I also have 2 test classes, one testing locally and one testing all methods over xml-rpc.

  • How can I resolve ASP.NET "~" app paths to the website root without a Control being present?

    - by jdk
    I want to Resolve "~/whatever" from inside non-Page contexts such as Global.asax (HttpApplication), HttpModule, HttpHandler, etc. but can only find such Resolution methods specific to Controls (and Page). I think the app should have enough knowledge to be able to map this outside the Page context. No? Or at least it makes sense to me it should be resolvable in other circumstances, wherever the app root is known. Update: The reason being I'm sticking "~" paths in the web.configuration files, and want to resolve them from the aforementioned non-Control scenarios. Update 2: I'm trying to resolve them to the website root such as Control.Resolve(..) URL behaviour, not to a file system path.

  • Triggering CSV download using Javascript?

    - by Sam Lee
    I have an url /reportcsv that generates a plain text csv with Content-type: text/csv and Content-disposition: attachment; filename=report.csv. I want trigger this csv to be downloaded using Javascript. I'm considering two methods: 1) Setting location.href = /reportcsv 2) Setting an iframe url to /reportcsv Both seem to work in Safari. I was wondering if there is any difference between them, or if one is recommended over the other. My main requirement is that I don't want the user to leave the current page.

  • Why is sqrt() not a method on Float?

    - by KaptajnKold
    In Ruby everything is an object. That's why I don't understand why we have the Math module. It seems to me that most (all?) of the functions in the Math module should have been methods on the numeric types like Integer, Float and so on. E.g. instead of Math.sqrt(5) it would make more sense to have 5.sqrt The same goes for sin, cos, tan, log10 and so on. Does anyone know why all these functions ended up in the Math module?

  • Why is run() not immediately called when start() called on a thread object in java

    - by pi
    Or is it? I have a thread object from: Thread myThread = new Thread(pObject); Where pObject is an object of a class implementing the Runnable interface and then I have the start method called on the thread object like so: myThread.start(); Now, my understanding is that when start() is called, the JVM implicitly (and immediately) calls the run() method which may be overridden (as it is in my case) However, in my case, it appears that the start() method is not called immediately (as desired) but until the other statements/methods are completed from the calling block i.e. if I had a method after the start() call like so: myThread.start(); doSomethingElse(); doSomthingElse() gets executed before the run() method is run at all. Perhaps I am wrong with the initial premise that run() is always called right after the start() is called. Please help! The desired again is making executing run() right after start(). Thanks.

  • PHP - WideImage class cropping

    - by Kolind
    I am trying to crop a large image to make thumbnails. But I can't get WideImage to save the file. I've tried the following: 1st method: $img = WideImage::load('../files/' . $file_name)->crop('center', 'center', 200, 200); $img->saveToFile('../files/thumb/thumb_' . $file_name); 2nd method: $img = WideImage::load('../files/' . $file_name)->crop('center', 'center', 200, 200); $img->copy('../files/thumb/thumb_' . $file_name); But nothing seems to happen, when I am performing any of these methods. I am getting no errors and no thumbnails. Am I doing something wrong here?

  • Vim and clang_complete, how to explicitly compile my code

    - by puller
    I use Vim with clang_complete for omnicompletion. The plugin is automatically triggered when I need completion, e.g., after I type . or -> to access an object members or methods (see attached screenshot). The plugin works really nice, however I would need a way to trigger it manually (i.e. to compile my code for syntax checking). This is useful for two reasons: Static syntax checking Clear previous errors which have been fixed (which otherwise will remain in their buffer). See the two screenshots below for a better understanding. Any help is appreciated. Thanks. Screenshot 1 Screenshot 2

  • UIWebView: Media Player Rotates View Controller

    - by RileyE
    I'm encountering an issue while using a webview. My app is currently a portrait application, but when a media player loads in a webview within my app, the user can rotate the player, which rotates my view controller as well. I know I can get a notification for when the player comes up and disappears, but is there a way to prevent it from rotating the controller in the first place? It doesn't seem like anyone has an answer. I have all of the standard "don't rotate unless if I tell you to" methods and plist values, but its still rotating. Its only when I load up a webview and the media player loads over it. If I rotate my device, the media player rotates along with it, which feels natural, but when I go back to the webview view controller, its rotated, which isn't good.

  • ExceptionHandling with Spring 3

    - by mjf
    I have this controller: @RequestMapping(value = "*.xls", method = RequestMethod.GET) public String excel(Model model) { return "excel"; The excel wiew opens actually a ExcelViewer, which is build in method protected void buildExcelDocument(Map<String, Object> map, WritableWorkbook ww, HttpServletRequest hsr, HttpServletResponse hsr1) throws Exception { Class.writecontent Class.writeMoreContent Called methods write content to the Excel sheet and they can throw e.g biffException. How can I show a certain error page when Exception is occured? I tried this @Controller public class ExcelController { @ExceptionHandler(BiffException.class) public String handleException(BiffException ex) { return "fail"; } @RequestMapping(value = "*.xls", method = RequestMethod.GET) public String excel(Model model) { return "excel"; } } But I'm getting the server's error message about Exceptions. Maybe a bean definition missing?

  • How to call same method for a list of objects?

    - by Dmitry
    Suppose code like this: class Base: def start(self): pass def stop(self) pass class A(Base): def start(self): ... do something for A def stop(self) .... do something for A class B(Base): def start(self): def stop(self): a1 = A(); a2 = A() b1 = B(); b2 = B() all = [a1, b1, b2, a2,.....] Now I want to call methods start and stop (maybe also others) for each object in the list all. Is there any elegant way for doing this except of writing a bunch of functions like def start_all(all): for item in all: item.start() def stop_all(all): .....

  • Is there a limit to the number of DataContracts that can be used by a WCF Service?

    - by Chris
    Using WCF3.5SP1, VS2008. Building a WCF service that exposes about 10 service methods. We have defined about 40 [DataContract] types that are used by the service. We now experience that adding an additional [DataContract] type to the project (in the same namespace as the other existing types) does not get properly exposed. The new type is not in the XSD schemas generated with the WSDL. We have gone so far as to copy and rename an existing (and working) type, but it too is not present in the generated WSDL/XSD. We've tried this on two different developer machines, same problem. Is there a limit to the number of types that can exposed as [DataContract] for a Service? per Namespace?

  • A 'do' statement at the end of my perl script never runs

    - by Jeremy Petzold
    In my main script, I am doing some archive manipulation. Once I have completed that, I want to run a separate script to upload my archives to and FTP server. Separately, these scripts work well. I want to add the FTP script to the end of my archive script so I only need to worry about scheduling one script to run and I want to guarantee that the first script completes it work before the FTP script is called. After looking at all the different methods to call my FTP script, I settled on 'do', however, when my do statement is at the end of the script, it never runs. When I place it in my main foreach loop, it runs fine, but it runs multiple times which I want to avoid since the FTP script can handle having multiple archives to upload. Is there something I am missing? Why does it not run? Thanks

  • How to handle server-client requests

    - by Layne
    Currently I'm working on a Server-Client system which will be the backbone of my application. I have to find the best way to send requests and handle them on the server-side. The server-side should be able to handle requests like this one: getPortfolio -i 2 -d all In an old project I decided to send such a request as string and the server application had to look up the first part of the string ("getPortfolio"). Afterwards the server application had to find the correct method in a map which linked the methods with the the first part of the string ("getPortfolio"). The second part ("-i 2 -d all") got passed as parameter and the method itself had to handle this string/parameter. I doubt that this is the best solution in order to handle many different requests.

  • EJB injection in Glassfish webapp

    - by g051051
    I've got an app that is trying to use @EJB annotation to inject remote references to EJBs in my ejb.jar file. I'm getting inconsistent results. In one case, I have a listener in web.xml that gets called and apparently has the EJB injected correctly, since I can see it connecting to the EJB and calling methods on it. In another class (a struts2 action) I get NPE when it tries to access the EJB reference. As far as I can tell, they're identical calls, in Java classes that live in the same .war file. As a work around, I added code in the constructor to lookup the EJBs by their global JNDI names, and it works fine. I just can't figure out why one @EJB works and not another.

  • Referencing the current jQuery object in a chain?

    - by Lance McNearney
    At DevDays in SF last year (before jQuery 1.4 was released), I thought they mentioned an upcoming feature in 1.4 that would allow you to reference the current jQuery object while in a chain. I've read through all of the 1.4 improvements and wasn't able to find it. Does anyone know how this can be done? Example Being able to access the current jQuery object would be helpful when working with methods that are in relation to the current object like .next(): // Current way var items = $(this).closest('tr'); items = items.add(items.next(':not([id])')); // Magical 1.4 way? Is there a "chain"-like object? var items = $(this).closest('tr') .add(chain.next(':not([id])'));

  • JavaScript Library Design

    - by JSMan2034
    I have a general question about the design of JavaScript Libraries. I am trying to consolidate common methods into one js file so they can be reused by different scripts. I have taken a look at how the JSON library is structured and believe it was a good approach. JSON for Javascript. So they start off creating an instance of the class: if (!this.JSON) { this.JSON = {}; } Then they do this: (function () { if (typeof JSON.stringify !== 'function') { JSON.stringify = function (value, replacer, space) { This is works perfect if you just want to do JSON.[function_name], but what if I want to have a more structured library such that I want: JSON.[subgroup].[function]. How would I structure my JS library in such a way? Any links to resources are greatly appreciated, thanks.
