  • Why not write all tests at once when doing TDD? [closed]

    - by RichK
    Possible Duplicate: Why not write all tests at once when doing TDD? The Red - Green - Refactor cycle for TDD is well established and accepted. We write one failing unit test and make it pass as simply as possible. What are the benefits to this approach over writing many failing unit tests for a class and make them all pass in one go. The test suite still protects you against writing incorrect code or making mistakes in the refactoring stage, and code coverage should be just as high, so what's the harm? Sometimes it's easier to write all the tests first as a form of 'brain dump' to quickly write down all the expected behavior in one go.

  • Should Scala IDE Worksheets be part of your open git repository?

    - by JacobusR
    Those familiar with Scala IDE will know about the great testing environment offered by the Scala Worksheet. You can scribble and scratch, much like in the REPL, but with all the goodness added by the IDE as a whole (refactoring, saving, error checking, etc). When you create a worksheet, it is created with the .sc extension, and also creates a artifact under a hidden directory called .worksheet. This is all fine and dandy, but should one include these in your public .git repositories? People who does not use Scala IDE (or older versions) may find these files confusing. On the other hand, making some of your experiments public to developers who are using Scala IDE, may give them a quick start into experimenting and learning the project.

  • Can all code be represented as a series of Map / Filter / Reduce operations?

    - by Mongus Pong
    I have recently been refactoring large chunks of code and replacing them with Linq queries. Removing the language bias - Linq is essentially a set of Map / Filter and Reduce operations that operate on a sequence of data. This got me thinking, how far would I theoretically be able to take this. Would I be able to rewrite the whole code base into a series (or even a single) of Map / Filter and Reduce operations. Unfortunately I get paid to do useful stuff, so I haven't been able to experiment much further, but I can't think of any code structure that couldn't be re structured as such. Side effected code can be dealt with via monads.. Even output is essentially mapping memory addresses to screen addresses. Is there anything that couldn't be (theoretically) rewritten as a Linq query?

  • Variable names for Contact Information bits

    - by RustyTheBoyRobot
    I am in the middle of refactoring code and would like to get some ideas on variable naming so that my new names clearly represent the data they hold. I have a class called ContactMethod which makes sense to me; each instance is a different way to contact someone. My problem comes when naming the properties of ContactMethod. For example, one instance might be a Fax number of 555-555-5555 while another could be an Email address of [email protected]; I've got a property called contactMethodType to hold the values "fax" or "email", but I don't know what to call the "555-555-5555" or "[email protected]" part. Has anyone here created a good generic name for this piece of contact information? (PS - the old convention was to call it a "Phone" with fields "phoneType" holding the "fax"/"email" value and "phoneId" holding the number/address. Yuck.)

  • PHP : Symfony sort en version 2.1 définitive, gestion des dépendances avec Composer, formulaires plus efficaces et Mailer plus performant

    Symfony2 est un projet très communautaire, depuis le début (des centaines de bundles étaient disponibles bien avant les premières RC de la 2.0), une tendance qui se confirme : 250 contributeurs, 1 000 pull requests sur GitHub pour la première version beta de Symfony 2.1 ! Après les difficultés de migration avec symfony 1.x, l'équipe a tenté autant que possible de restreindre les changements à même de casser la rétrocompatibilité ; de même, le refactoring du module de formulaires a fait que la version finale de la 2.1 devrait sortir en août, afin de concentrer autant que possible les changements et faire que de plus en plus de code ne devra pas être modifié lors de la migration d'une version à l'autre.

  • How can I apply Readme Driven Development to an ongoing project?

    - by Metalcoder
    I'm assigned to a project where the goal is to update an existing software. This software was developed in a totally ad hoc manner, which means that any documentation generated is outdated, confused and just plain useless. I do not want to retroactivelly produce all the missing artifacts, since this would just be a waste of time. The code base is ugly, and really need some serious refactoring, but this is another story. What I want is to apply Readme Driven Development to guide this project. So, basically, I want to write a Readme, which will document every change meaningful at the user level. The problem is, I have no idea about how to structure this document. For me, it's pretty clear that it should have a different layout than the traditional Readme. I really want to document changes, and not the current state of affairs. Any ideas?

  • code cowboy on the team

    - by MK01
    How do you deal with a team member who is senior to you and always jumps on other people's projects and completes them over night or over the weekend? She seems to work 80 hour weeks whether there is an emergency or not and it is somewhat difficult to predict which part of your todo list she is going to strike next. Sometimes days of your work are wasted because on Monday morning you find a checkin completing the project you've spent most of the previous week working on. To people asking of the quality: Usually it is quite good but: there is also a lot of refactoring of code involved, including code 'owned' by other team members, w/o regard for the test coverage, with the obvious results.

  • Encouraging business and team members to write more code

    - by Aliixx
    I am really interested to hear any ideas or working practices that can be adopted to encourage our team of developers to write more code. A little background here is involves a team of varying disciplines, experience and qualities and the nature of the work has a large focus on bug fixes and business logic / data validation over writing lots of new greenfield code or even refactoring. We are attempting to move to a more Agile philosophy and really what would be great is to hear any ideas that can be sold to the team and / or the business with the aim of: Writing more new code to improve experience, abilities and increase exposure to newer and emerging patterns and practices. Energizing the effort of the team and inspire. Encouraging wider input of new ideas, patterns and practices from the team as a whole. I would be very interested (and grateful) to hear any ideas or examples of ideas that can help here. Thanks!

  • How much abstraction is too much?

    - by Daniel Bingham
    In an Object Oriented Program: How much abstraction is too much? How much is just right? I have always been a nuts and bolts kind of guy. I understood the concept behind high levels of encapsulation and abstraction, but always felt instinctively that adding too much would just confuse the program. I always tried to shoot for an amount of abstraction that left no empty classes or layers. And where in doubt, instead of adding a new layer to the hierarchy, I would try and fit something into the existing layers. However, recently I've been encountering more highly abstracted systems. Systems where everything that could require a representation later in the hierarchy gets one up front. This leads to a lot of empty layers, which at first seems like bad design. However, on second thought I've come to realize that leaving those empty layers gives you more places to hook into in the future with out much refactoring. It leaves you greater ability to add new functionality on top of the old with out doing nearly as much work to adjust the old. The two risks of this seem to be that you could get the layers you need wrong. In this case one would wind up still needing to do substantial refactoring to extend the code and would still have a ton of never used layers. But depending on how much time you spend coming up with the initial abstractions, the chance of screwing it up, and the time that could be saved later if you get it right - it may still be worth it to try. The other risk I can think of is the risk of over doing it and never needing all the extra layers. But is that really so bad? Are extra class layers really so expensive that it is much of a loss if they are never used? The biggest expense and loss here would be time that is lost up front coming up with the layers. But much of that time still might be saved later when one can work with the abstracted code rather than more low level code. So when is it too much? At what point do the empty layers and extra "might need" abstractions become overkill? How little is too little? Where's the sweet spot? Are there any dependable rules of thumb you've found in the course of your career that help you judge the amount of abstraction needed?

  • ReSharper-like addon for NetBeans

    - by Ondrej Slinták
    Hello, is there any ReSharper-like addon for NetBeans (preferably 6.8)? I'm using NetBeans for PHP. I need following features: add some kind of code analysis add some intelligent refactoring interface enhance current code completion system add more options to code highlighting Currently I'm using multiple external tools, which aren't exactly user-friendly and I'd like to, preferably, have it all in one tool. Perhaps some other PHP IDE have something like this. EDIT: Bit more details in my answer to Jani Hartikainen.

  • Google Mock for iPhone development?

    - by Cliff
    I have an interesting situation where I am refactoring a bunch of ObjC iPhone code to create a C++ API. I'm a novice to C++ and looking into C++ mocking frameworks to augment the work I'd done using OCUnit and poor man's mocks. I ran across googlemock and wanted to know if anyone has ever used it for iPhone development? Also, how can I share this (or mockpp) with other devs as it is an installable package and doesn't seem to lend itself to checking into a repository?

  • Using VCL for the web (intraweb) as a trick for adding web interface to a legacy non-tiered (2 tiers

    - by user193655
    My team is maintaining a huge Client Server win32 Delphi application. It is a client/server application (Thick client) that uses DevArt (SDAC) components to connect to SQL Server. The business logic is often "trapped" in Component's event handlers, anyway with some degree of refactoring it is doable to move the business logic in common units (a big part of this work has already been done during refactoring... Maintaing legacy applications someone else wrote is very frustrating, but this is a very common job). Now there is the request of a web interface, I have several options of course, in this question i want to focus on the VCL for the web (intraweb) option. The idea is to use the common code (the same pas files) for both the client/server application and the web application. I heard of many people that moved legacy apps from delphi to intraweb, but here I am trying to keep the Thick client too. The idea is to use common code, may be with some compiler directives to write specific code: {$IFDEF CLIENTSERVER} {here goes the thick client specific code} {$ELSE} {here goes the Intraweb specific code} {$ENDIF} Then another problem is the "migration plan", let's say I have 300 features and on the first release I will have only 50 of them available in the web application. How to keep track of it? I was thinking of (ab)using Delphi interfaces to handle this. For example for the User Authentication I could move all the related code in a procedure and declare an interface like: type IUserAuthentication= interface['{0D57624C-CDDE-458B-A36C-436AE465B477}'] procedure UserAuthentication; end; In this way as I implement the IUserAuthentication interface in both the applications (Thick Client and Intraweb) I know that That feature has been "ported" to the web. Anyway I don't know if this approach makes sense. I made a prototype to simulate the whole process. It works for a "Hello world" application, but I wonder if it makes sense on a large application or this Interface idea is only counter-productive and can backfire. My question is: does this approach make sense? (the Interface idea is just an extra idea, it is not so important as the common code part described above) Is it a viable option? I understand it depends a lot of the kind of application, anyway to be generic my one is in the CRM/Accounting domain, and the number of concurrent users on a single installation is typically less than 20 with peaks of 50. EXTRA COMMENT (UPDATE): I ask this question because since I don't have a n-tier application I see Intraweb as the unique option for having a web application that has common code with the thick client. Developing webservices from the Delphi code makes no sense in my specific case, so the alternative I have is to write the web interface using ASP.NET (duplicating the business logic), but in this case I cannot take advantage of the common code in an easy way. Yes I could use dlls maybe, but my code is not suitable for that.

  • Best IDE for javascript server development

    - by MatteS
    After reading http://www.pragprog.com/magazines/2010-03/javascript-its-not-just-for-browsers-any-more im wondering which is the best IDE to develop service-side javascript applications? I want a nice development environment with commonjs and node etc. Preferebly windows but anything is interesting really. Is there any IDE with some nifty refactoring tools, maybe some intellisense-like function, etc etc.. Or is it notepad++ ftw?

  • How are you using IronPython?

    - by Will Dean
    I'm keen to drink some modern dynamic language koolaid, so I've believed all the stuff on Michael Foord's blog and podcasts, I've bought his book (and read some of it), and I added an embedded IPy runtime to a large existing app a year or so ago (though that was for someone else and I didn't really use it myself). Now I need to do some fairly simple code generation stuff, where I'm going to call a few methods on a few .net objects (custom, C#-authored objects), create a few strings, write some files, etc. The experience of trying this leaves me feeling like the little boy who thinks he's the only one who can see that The Emperor has no clothes on. If you're using IronPython, I'd really appreciate knowing how you deal with the following aspects of it: Code editing - do you use the .NET framework without Intellisense? Refactoring - I know a load of 'refactoring' is about working around language-related busywork, so if Python is sufficiently lightweight then we won't need that, But things like renames seem to me to be essential to iteratively developing quality code regardless of language. Crippling startup time - One of the things which is supposed to be good about interpreted languages is the lack of compile time leading to fast interactive development. Unfortunately I can compile a C# application and launch it quicker than IPy can start up. Interactive hacking - the IPy console/repl is supposed to be good for this, but I haven't found a good way to take the code you've interactively arrived at and persist it into a file - cut and paste from the console is fairly miserable. And the console seems to hold references to .NET assemblies you've imported, so you have to quit it and restart it if you're working on the C# stuff as well. Hacking on C# in something like LinqPad seems a much faster and easier way to try things out (and has proper Intellisense). Do you use the console? Debugging - what's the story here? I know someone on the IPy team is working on a command-line hobby-project, but let's just say I'm not immediately attracted to a command line debugger. I don't really need a debugger from little Python scripts, but I would if I were to use IPy for scripting unit tests, for example. Unit testing - I can see that dynamic languages could be great for this, but is there any IDE test-runner integration (like for Resharper, etc). The Foord book has a chapter about this, which I'll admit I have not yet read properly, but it does seem to involve driving a console-mode test-runner from the command prompt, which feels to be an enormous step back from using an integrated test runner like TestDriven.net or Resharper. I really want to believe in this stuff, so I am still working on the assumption that I've missed something. I would really like to know how other people are dealing with IPy, particularly if they're doing it in a way which doesn't feel like we've just lost 15 years'-worth of tool development.

  • Avoiding a large number of custom EventArgs?

    - by Brian Ortiz
    The class library I'm refactoring has a large number of events (over 50) each with its own Delegate, even though many have the same arguments. I starting switching them all over to use EventHandler and custom EventArgs but it is proving to be tedious and time consuming. Is there an easier way to handle a situation like this, when you have a huge number of events?

  • Refactor file copy in Visual Studio?

    Does Visual Studio / Resharper support this? By refactor copy I mean to be able to enter new class name in some dialog, and to have the tool do all the refactoring (renaming) for you. No Copy of ... file names, and no error upon having two classes with same name in the project. Netbeans does this out-of-the-box :(

    Hello I am a beginning android developer using windows and the eclipse IDE to develop java android applications.I have published one game but there is a free version of the game and a paid version. The google market insists that the different versions must have different package names. So far i have been refactoring the package with 2 different names and changing the R resource file import each time i build the different versions. The code is 99% the same for both versions.Is there a better way?
