  • Setup and Use SpecFlow BDD with DevExpress XAF

    - by Patrick Liekhus
    Let’s get started with using the SpecFlow BDD syntax for writing tests with the DevExpress XAF EasyTest scripting syntax.  In order for this to work you will need to download and install the prerequisites listed below.  Once they are installed follow the steps outlined below and enjoy. Prerequisites Install the following items: DevExpress eXpress Application Framework (XAF) found here SpecFlow found here Liekhus BDD/XAF Testing library found here Assumptions I am going to assume at this point that you have created your XAF application and have your Module, Win.Module and Win ready for usage.  You should have also set any attributes and/or settings as you see fit. Setup So where to start. Create a new testing project within your solution. I typically call this with a similar naming convention as used by XAF, my project name .FunctionalTests (i.e. AlbumManager.FunctionalTests). Add the following references to your project.  It should look like the reference list below. DevExpress.Data.v11.x DevExpress.Persistent.Base.v11.x DevExpress.Persistent.BaseImpl.v11.x DevExpress.Xpo.v11.2 Liekhus.Testing.BDD.Core Liekhus.Testing.BDD.DevExpress TechTalk.SpecFlow TestExecutor.v11.x (found in %Program Files%\DevExpress 2011.x\eXpressApp Framework\Tools\EasyTest Right click the TestExecutor reference and set the “Copy Local” setting to True.  This forces the TestExecutor executable to be available in the bin directory which is where the EasyTest script will be executed further down in the process. Add an Application Configuration File (app.config) to your test application.  You will need to make a few modifications to have SpecFlow generate Microsoft style unit tests.  First add the section handler for SpecFlow and then set your choice of testing framework.  I prefer MS Tests for my projects. Add the EasyTest configuration file to your project.  Add a new XML file and call it Config.xml. Open the properties window for the Config.xml file and set the “Copy to Ouput Directory” to “Copy Always”. You will setup the Config file according to the specifications of the EasyTest library my mapping to your executable and other settings.  You can find the details for the configuration of EasyTest here.  My file looks like this Create a new folder in your test project called “StepDefinitions”.  Add a new SpecFlow Step Definition file item under the StepDefinitions folder.  I typically call this class StepDefinition.cs. Have your step definition inherit from the Liekhus.Testing.BDD.DevExpress.StepDefinition class.  This will give you the default behaviors for your test in the next section. OK.  Now that we have done this series of steps, we will work on simplifying this.  This is an early preview of this new project and is not fully ready for consumption.  If you would like to experiment with it, please feel free.  Our goals are to make this a installable project on it’s own with it’s own project templates and default settings.  This will be coming in later versions.  Currently this project is in Alpha release. Let’s write our first test Remove the basic test that is created for you. We will not use the default test but rather create our own SpecFlow “Feature” files. Add a new item to your project and select the SpecFlow Feature file under C#. Name your feature file as you do your class files after the test they are performing. Writing a feature file uses the Cucumber syntax of Given… When… Then.  Think of it in these terms.  Givens are the pre-conditions for the test.  The Whens are the actual steps for the test being performed.  The Thens are the verification steps that confirm your test either passed or failed.  All of these steps are generated into a an EasyTest format and executed against your XAF project.  You can find more on the Cucumber syntax by using the Secret Ninja Cucumber Scrolls.  This document has several good styles of tests, plus you can get your fill of Chuck Norris vs Ninjas.  Pretty humorous document but full of great content. My first test is going to test the entry of a new Album into the application and is outlined below. The Feature section at the top is more for your documentation purposes.  Try to be descriptive of the test so that it makes sense to the next person behind you.  The Scenario outline is described in the Ninja Scrolls, but think of it as test template.  You can write one test outline and have multiple datasets (Scenarios) executed against that test.  Here are the steps of my test and their descriptions Given I am starting a new test – tells our test to create a new EasyTest file And (Given) the application is open – tells EasyTest to open our application defined in the Config.xml When I am at the “Albums” screen – tells XAF to navigate to the Albums list view And (When) I click the “New:Album” button – tells XAF to click the New Album button on the ribbon And (When) I enter the following information – tells XAF to find the field on the screen and put the value in that field And (When) I click the “Save and Close” button – tells XAF to click the “Save and Close” button on the detail window Then I verify results as “user” – tells the testing framework to execute the EasyTest as your configured user Once you compile and prepare your tests you should see the following in your Test View.  For each of your CreateNewAlbum lines in your scenarios, you will see a new test ready to execute. From here you will use your testing framework of choice to execute the test.  This in turn will execute the EasyTest framework to call back into your XAF application and test your business application. Again, please remember that this is an early preview and we are still working out the details.  Please let us know if you have any comments/questions/concerns. Thanks and happy testing.

  • Speech Recognition

    - by DesigningCode
    Today I was asked to write a wee application for someone so that they could turn pages on their ebooks without having to reach for their keyboard or mouse… that way they could do craft or knit or whatever they are doing while they are reading. I vaguely remember that windows has something built in, but have never really played with it before.   I have in the past turned on the screen reader and impressed my kids by making the computer saying “amusing” phrases along the lines of “Zac has a smelly bum”. So instead of firing up Visual Studio and getting stuck into the juciy task of writing a speech recognition program…. I typed “speech recognition” into the start menu of my windows 7 computer.   And wow!  I’ve been playing with it for the last 40 minutes or so and have been most impressed.   Dictation wise it certainly misses stuff or gets the wrong words, but I did the training and it certainly improved. But what I’m enjoying is controlling windows. for instance, to start this blog entry  I said “Open Writer”  and it worked no problem.    In fact after I muddled my way through getting going with speech recognition I enjoyed saying “Open notepad” … “close”  over and over again. It allows you to click anywhere on the screen, just say “mousegrid”   and a 1-9 numbered grid comes up,  say a number and it puts a smaller 1-9 numbered grid, and you hone in, till the middle square is on a place you want to click, then you say “click” or “double click”.  if you want to enter a key, say “Press Tab”  for example.   inside programs it understands menu entries.  In fact, while writing this I just said “File”  “Save” and it happily saved. I think I will play around with this for a while more and try it out in visual studio.   Might be quite good for being able to do menu entries instead of grabbing for my mouse…. can keep my hands on the keyboard. ok, wasn’t the first post I wanted to do on geeks with blogs! but hey…   will do some techy posts soon.

  • Language Club – Battle of the Dynamic Languages

    - by Ben Griswold
    After dedicating the last eight weeks to learning Ruby, it’s time to move onto another language.  I really dig Ruby.  I really enjoy its dynamism and expressiveness and always-openness and it’s been the highlight of our coding club for me so far. But that’s just my take on the language.  I know a lot of coders who’s stomachs turn with the mere thought of Ruby.  They say it’s Ruby’s openness which has them feeling uneasy.  I’d say “write a bunch of tests and get over it,” but I figure there must be more to it than always open classes and possible method collisions. Yes, there’s something else to it alright. The folks who didn’t fall head over heals for Ruby are already in love with Python.  You might remember that Python was the first language we tackled in our coding club.  My time with Python was okay but it didn’t feel as natural to me as Ruby.  But let’s say we started with Ruby and then moved onto Python.  Would I see Python in a different light right now.  Might I even prefer Python over Ruby?  I suppose it’s possible but it’s pretty tough to test that theory – unless we visit Python for a second time. That’s right. The language club is going to focus on Python again and in my attempt to learn Python – yet again – in the open, I’ll be posting my solutions here just as I did for Ruby.  We don’t always have second chances so I going about this relearning with two primary goals in mind:  First, I’m going to use IronPython and the IronPython tools which provide a Python code editor, a file-based project system, and an interactive Python interpreter, all inside Visual Studio 2010.  As a note, the IronPython tools are now part of the main IronPython installer which is Version 2.7 Alpha 1 (not the latest stable version, 2.6.1) and I’d be crazy not to use them.  Second, I’d like to make sure I’m still learning Python without a complete MS skew so I’m going to run my code through Eclipse using the PyDev plugin as well.  Heck, I might use IDLE too. I already have this setup on my machine so it’s no big deal. Okay, that’s it for now.  I worked on the first ten Euler problems last night and the solutions will be posted shortly. Wish me luck.

  • How to Make Ubuntu Play MP3 Files

    - by Trevor Bekolay
    Because of licensing issues, Ubuntu is unable to play MP3s out of the box. We’ll show you how to play MP3s and other restricted file formats in about four mouse clicks. The philosophy behind Ubuntu is that software should be free and accessible to all. Whether MP3 and other file formats are free is unclear in many countries, so Ubuntu does not include software to read these file formats by default. Fortunately, it does include a package that installs the most commonly used file formats all at once, including a Flash plugin for Firefox. Note: These instructions are for Ubuntu 10.04. There are small differences for earlier versions of Ubuntu. Play MP3 Files Open the Ubuntu Software Center, found in the Applications menu.   Click on View and ensure that All Software is selected. Type “restricted extras” into the search box at the top-right. Find the Ubuntu restricted extras package and click Install. Enter your password when prompted. Once the install is complete, close out of Ubuntu Software Center, and you’ll be able to play MP3 files! To confirm this, we’ll open up Rhythmbox, found in the Sound & Video section of the Applications menu. Our test MP3 plays with no problems! Note: If Rhythmbox tells you that MP3 plugins are not installed, close Rhythmbox and reopen it. You should not have to install anything extra through Rhythmbox.   Despite this extra step, playing the most common audio and video file formats – including Flash videos on the internet – is simple. All the software comes installed, you just have to teach them how to read your files.

  • ORM Profiler v1.1 has been released!

    - by FransBouma
    We've released ORM Profiler v1.1, which has the following new features: Real time profiling A real time viewer (RTV) has been added, which gives insight in the activity as it is received by the client, in two views: a chronological connection overview and an activity graph overview. This RTV allows the user to directly record to a snapshot using record buttons, pause the view, mark a range to create a snapshot from that range, and view graphs about the # of connection open actions and # of commands per second. The RTV has a 'range' in which it keeps live data and auto-cleans data that's older than this range. Screenshot of the activity graphs part of the real-time viewer: Low-level activity tab A new tab has been added to the Application tabs: the Low-level activity tab. This tab shows the main activity as it has been received over the named pipe. It can help to get insight in the chronological activity without the grouping over connections, so multiple connections at the same time per thread are easier to spot. Clicking a command will sync the rest of the application tabs, clicking a row will show the details below the splitter bar, as it is done with the other application tabs as well. Default application name in interceptor When an empty string or null is passed for application name to the Initialize method of the interceptor, the AppDomain's friendly name is used instead. Copy call stack to clipboard A call stack viewed in a grid in various parts of the UI is now copyable to the clipboard by clicking a button. Enable/Disable interceptor from the config file It's now possible to enable/disable the interceptor Initialization from the application's config file, using: Code: <appSettings> <add key="ORMProfilerEnabled" value="true"/> </appSettings> if value is true, the interceptor's Initialize method will proceed. If the value is false, the interceptor's Initialize method will not proceed and initialization won't be performed, meaning no interception will take place. If the setting is absent, or misconfigured, the Initialize method will proceed as normal and perform the initialization. Stored procedure calls for select databases are now properly displayed as a call For the databases: SQL Server, Oracle, DB2, Sybase ASA, Sybase ASE and Informix a stored procedure call is displayed as an execute/call statement and copy to clipboard works as-is. I'm especially happy with the new real-time profiling feature in ORM Profiler, which is the flagship feature for this release: it offers a completely new way to use the profiler, namely directly during debugging: you can immediately see what's going on without the necessity of a snapshot. The activity graph feature combined with the auto-cleanup of older data, allows you to keep the profiler open for a long period of time and see any spike of activity on the profiled application.

  • Do I need to match hardware on a Mac to my PC to get the same user experience?

    - by Darth
    I've been playing around with the thought of moving from a PC to a Mac. if you don't want to read this, skip to the "upgrade options" My current setup Most of my time I spent moving back and forth between Linux and Windows. During the last upgrade to Vista, I got myself pc with Core 2 Quad, 8GB of RAM and GeForce 9800GTX+. Currently I'm running dual boot between Ubuntu 10.04 and Windows Vista x64. Most of my work, around 80%, I can do on Ubuntu, which is mostly Ruby/Java programming. If that was all I needed, Ubuntu would be really great. However, I also do quite a lot of Photography and Design, which forces me to use Adobe software (not only Photoshop). I also work with Wacom Intuos4 tablet, which doesn't really have great support on Linux machines. I've tried virtualization both ways (Linux in Win and Win in Linux), but neither was anywhere near satisfying. These are those of many many reasons I want to move to OS X. Upgrade options This is how I see my upgrade options: Mac Mini - cheapest solution, but worst performance iMac - more expensive, better performing with second LCD for free Mac Pro - could match my current PC performance, currently outside of the price range When I compare the Mac hardware vs my current PC, it will be always worse, unless I decide to pump in a lot of money. The question that comes to my head, do I need to match my current PC hardware to get the same user experience with a Mac? If I look at it from the Vista point of view, 2GB RAM is as low as it gets, 4GB is usable ... and the 8GB runs very smoothly. PC HW != Mac HW? If I bought the Mac Mini for roughly the same price I paid for my PC (Core 2 Quad with 8GB RAM), I'd get Core 2 Duo with 4GB RAM. But I don't want to run Vista on it, so I can't compare the hardware directly. Say that I want to do the same things on the Mac Mini as I do on my PC, eg. open up 50 tabs in Google Chrome and start working with a large PSD in Photoshop (couple hundred MB), would running on Mac OS X compensate for the lower hardware performance? My point is, that if I'm about to upgrade, I wouldn't like to upgrade to hardware that runs a lot slower. Good analogy for this is Vista vs Ubuntu, where you can run Ubuntu smoothly on a low end laptop, but in Vista, you'd be happy to open a browser. Does the same principle apply to OS X?

  • Set App Windows to Always be on Top

    - by Asian Angel
    Sometimes you have a small app or other software that you want to keep topmost but how do you keep it on top without a lot of hassle? If this sounds like your situation then you might want to have a look at OnTop. Before For our example we had four individual apps open…any of the four could easily be on top at the moment. OnTop in Action The exe file for the app comes in a zip file. Simply unzip the file, place it in the Program Files Folder, create a shortcut and you are ready to go. Once you start OnTop you will see a new System Tray Icon…right click to access the Context Menu with a list of currently open apps. We decided to set Winamp to be always topmost first. Note: OnTop detected all three individual sections of our Winamp Player along with the individual monitors running in our Taskbar. Clicking on Paint.NET brought it forward over Firefox and Microsoft Word but Winamp was still sitting on top. Clicking on Microsoft Word next still did not affect Winamp’s topmost status. Nice. As soon as we switched the topmost status to Microsoft Word you can see that it immediately came to the front. One thing that we did note in our tests…the best method for switching topmost status is either to choose a different app or close the app that was topmost. Conclusion OnTop might be considered niche software but if you have an app window that you need to keep on top of other windows then you might want to give this small app a try.

    While Java SE churns and gets pushed back, the new initiatives do at least show OpenJDK is reinvigorating the Java space. The project has picked up speed just a little too late for the fifth anniversary of the open-sourcing of Java, but if these promised developments really do come together then that means next year should see a series of “one last things” missing from 2011.Matt Stephens in an article in the Register.

  • Python PyBluez loses Bluetooth connection after a while

    - by Travis G.
    I am using Python to write a simple serial Bluetooth script that sends information about my computer stats periodically. The receiving device is a Sparkfun BlueSmirf Silver. The problem is that, after the script runs for a few minutes, it stops sending packets to the receiver and fails with the error: (11, 'Resource temporarily unavailable') Noticing that this inevitably happens, I added some code to automatically try to reopen the connection. However, then I get: Could not connect: (16, 'Device or resource busy') Am I doing something wrong with the connection? Do I need to occasionally reopen the socket? I'm not sure how to recover from this type of error. I understand that sometimes the port will be busy and a write operation is deferred to avoid blocking other processes, but I wouldn't expect the connection to fail so regularly. Any thoughts? Here is the script: import psutil import serial import string import time import bluetooth sampleTime = 1 numSamples = 5 lastTemp = 0 TEMP_CHAR = 't' USAGE_CHAR = 'u' SENSOR_NAME = 'TC0D' #gauges = serial.Serial() #gauges.port = '/dev/rfcomm0' #gauges.baudrate = 9600 #gauges.parity = 'N' #gauges.writeTimeout = 0 #gauges.open() filename = '/sys/bus/platform/devices/applesmc.768/temp2_input' def parseSensorsOutputLinux(output): return int(round(float(output) / 1000)) def connect(): while(True): try: gaugeSocket = bluetooth.BluetoothSocket(bluetooth.RFCOMM) gaugeSocket.connect(('00:06:66:42:22:96', 1)) break; except bluetooth.btcommon.BluetoothError as error: print "Could not connect: ", error, "; Retrying in 5s..." time.sleep(5) return gaugeSocket; gaugeSocket = connect() while(1): usage = psutil.cpu_percent(interval=sampleTime) sensorFile = open(filename) temp = parseSensorsOutputLinux(sensorFile.read()) try: #gauges.write(USAGE_CHAR) gaugeSocket.send(USAGE_CHAR) #gauges.write(chr(int(usage))) #write the first byte gaugeSocket.send(chr(int(usage))) #print("Wrote usage: " + str(int(usage))) #gauges.write(TEMP_CHAR) gaugeSocket.send(TEMP_CHAR) #gauges.write(chr(temp)) gaugeSocket.send(chr(temp)) #print("Wrote temp: " + str(temp)) except bluetooth.btcommon.BluetoothError as error: print "Caught BluetoothError: ", error time.sleep(5) gaugeSocket = connect() pass gaugeSocket.close() EDIT: I should add that this code connects fine after I power-cycle the receiver and start the script. However, it fails after the first exception until I restart the receiver. P.S. This is related to my recent question, Why is /dev/rfcomm0 giving PySerial problems?, but that was more about PySerial specifically with rfcomm0. Here I am asking about general rfcomm etiquette.

  • SQL SERVER – Working with FileTables in SQL Server 2012 – Part 1 – Setting Up Environment

    - by pinaldave
    Filestream is a very interesting feature, and an enhancement of FileTable with Filestream is equally exciting. Today in this post, we will learn how to set up the FileTable Environment in SQL Server. The major advantage of FileTable is it has Windows API compatibility for file data stored within an SQL Server database. In simpler words, FileTables remove a barrier so that SQL Server can be used for the storage and management of unstructured data that are currently residing as files on file servers. Another advantage is that the Windows Application Compatibility for their existing Windows applications enables to see these data as files in the file system. This way, you can use SQL Server to access the data using T-SQL enhancements, and Windows can access the file using its applications. So for the first step, you will need to enable the Filestream feature at the database level in order to use the FileTable. -- Enable Filestream EXEC sp_configure filestream_access_level, 2 RECONFIGURE GO -- Create Database CREATE DATABASE FileTableDB ON PRIMARY (Name = FileTableDB, FILENAME = 'D:\FileTable\FTDB.mdf'), FILEGROUP FTFG CONTAINS FILESTREAM (NAME = FileTableFS, FILENAME='D:\FileTable\FS') LOG ON (Name = FileTableDBLog, FILENAME = 'D:\FileTable\FTDBLog.ldf') WITH FILESTREAM (NON_TRANSACTED_ACCESS = FULL, DIRECTORY_NAME = N'FileTableDB'); GO Now, you can run the following code and figure out if FileStream options are enabled at the database level. -- Check the Filestream Options SELECT DB_NAME(database_id), non_transacted_access, non_transacted_access_desc FROM sys.database_filestream_options; GO You can see the resultset of the above query which returns resultset as the following image shows. As you can see , the file level access is set to 2 (filestream enabled). Now let us create the filetable in the newly created database. -- Create FileTable Table USE FileTableDB GO CREATE TABLE FileTableTb AS FileTable WITH (FileTable_Directory = 'FileTableTb_Dir'); GO Now you can select data using a regular select table. SELECT * FROM FileTableTb GO It will return all the important columns which are related to the file. It will provide details like filesize, archived, file types etc. You can also see the FileTable in SQL Server Management Studio. Go to Databases >> Newly Created Database (FileTableDB) >> Expand Tables Here, you will see a new folder which says “FileTables”. When expanded, it gives the name of the newly created FileTableTb. You can right click on the newly created table and click on “Explore FileTable Directory”. This will open up the folder where the FileTable data will be stored. When you click on the option, it will open up the following folder in my local machine where the FileTable data will be stored: \\127.0.0.1\mssqlserver\FileTableDB\FileTableTb_Dir In tomorrow’s blog post as Part 2, we will go over two methods of inserting the data into this FileTable.

  • Compiling SDL under Windows with sdl-config

    - by DarrenVortex
    I have downloaded NXEngine (The Open Source version of Cave Story). I have a make file in the directory, which I execute using msys. However, the make file uses sdl-config: g++ -g -O2 -c main.cpp -D DEBUG `sdl-config --cflags` -Wreturn-type -Wformat -Wno-multichar -o main.o /bin/sh: sdl-config: command not found And apparently sdl-config does not exist under windows since there's no sdl installation. There's also no documentation on the official sourceforge website about this! What do I do?

  • How to Customize the Internet Explorer 8 Title Bar

    - by Mysticgeek
    If you’re looking for a way to personalize IE 8, one method is to customize the Title Bar. Here we look at a simple Registry hack that will get the job done. The Internet Explorer Title Bar is displayed on the top of the browser with the site name followed by Windows Internet Explorer by default. If you have a small office you might want to change it to the company name, or just change it something more personal at home.   Customize the IE 8 Title Bar Note: Before making any changes to the Registry, make sure to back it up. The first thing we need to do is open the Registry by typing regedit into the Search box in the Start Menu and hit Enter. With the Registry open, navigate to HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main. Then create a new String Value and name it Window Title. Right-click on the Window Title String and enter in whatever you want to display on the Title Bar in the Value data field and click OK. When you’re done, you should see the new String called Windows Title with whatever you entered in as the value. Close out of the Registry. Restart or launch Internet Explorer and you’ll now see your new text in the Title Bar. If you want to change it to something else, just go in and modify the Value data. If you want to switch it back to the default, just go back in and delete the string we created. A lot of times you’ll see corporate branding already in the title bar from your ISP or some computer company. To get rid of it, check out The Geek’s article on how to remove it. This should work with other versions of Internet Explorer as well.

    - by Asian Angel
    Is your computer or virtualization software unable to display the new 3D version of the Unity Interface in Ubuntu? Now you can access and enjoy the 2D version with just a little PPA magic added to your system! To add the new PPA open the Ubuntu Software Center, go to the Edit Menu, and select Software Sources. Access the Other Software Tab in the Software Sources Window and add the first of the PPAs shown below (outlined in red). The second PPA will be automatically added to your system. Once you have the new PPAs set up, go back to the Ubuntu Software Center and click on the PPA listing for Unity 2D on the left (highlighted with red in the image). Scroll down until you find the listing for “Unity interface for non-accelerated graphics cards – unity-2d” and click Install. Once that is done you are ready to go to System, Administration, and then select Login Screen in your Ubuntu Menu. Unlock the screen and select Unity 2D as the default session from the drop-down list as shown here. Log out and then back in to start enjoying that Unity 2D goodness! Here is how things will look when you click on the Ubuntu Menu Icon. Select the category that you would like to start with (such as Web) and get ready to have fun.

  • Website Editor control for WYSIWYG/regions

    - by Dan Smith
    For lack of a better title, let me try to explain further: I'm looking for a control that will allow me to have a library of "page elements" (such as a list of employees, or a photo gallery, or a contact form, etc) that could be dragged onto the page canvas. The page canvas could have pre-set regions/boxes where these items could be drug into, preventing the user from screwing up the pages layout. I'm looking for any pre-built commercial (or open-source with commercial use allowed) tools available like this.
