Agile Projects
WebTest Fixtures, FitNesse, Selenium and Integrated Windows Authentication
Sep 7th
As part of one of the latests coaching on implementing Scrum in a software development team, it was decided to implement ATDD and we decided to use FitNesse for preparing and writing of the tests and Selenium to execute them.
In order to link both Selenium and FitNesse, we use WebTests Fixtures (Thanks Gojko et al.)
The surprise that awaited us was a web application developed in. NET with Windows Integrated Authentication. Anyone who has been through this, would know that there is not much information online that would solve the problem. Except for a couple of modifications to the core of WebTest and a few isolated posts, we were unable to find a unified source to solve this problem.
From the beginning, we knew we didn’t want to modify the code of the testing tools we decided to use, to enable them to be updated as new versions come out without major problems, therefore, that solution was discarded.
After researching a while, we decided the best option was to have Selenium running an instance of Firefox onfigured enough to set Integrated Windows Authentication with no problems.
Context
FitNesse and Selenium are both installed and running as services on a windows server. FitNesse version is the one that comes with the download of WebTests Fixtures, while the version of Selenium is the latest, since that comes with WT supports up to Firefox 2, not 3.
Solution
In principle, we must create a new Firefox profile with a given configuration for user credentials under which the service is running Selenium are sent to the Web application in a transparent manner, without popups or alerts that prevent Selenium do its job. Then we configure selenium to lift the specific profile of Firefox, and not another.
Creating the Profile in Firefox
To create a new profile for firefox it’s important to be logged with the user under which the service is running Selenium. Once inside the system you must follow these steps (Note: This assumes Windows):
1. Run:
firefox.exe -ProfileManager
2. Click “Create Profile”
3. Naming Your profile. In our case we use “WebTest-FFPROFILE-IWA”
4. Select a folder. In our case we use “C:\webtest\WebTest-FFPROFILE-IWA”
5. Click “Finish”
6. Select “Do not ask at startup”
Configuring Profile in Firefox
1. Continuing from the previous step, select the newly created profile and click on “Start Firefox”
2. Go to “View-> Toolbars” and uncheck “Bookmarks”
3. Right click on the toolbar and select “Customize”
4. Select “Use Small Icons” and accept
5. Go to “Tools-> Options
6. In the tab “Main” setear “about: blank” homepage and off as “Show Downloads”
7. In the Tab “Perstañas” select new window to new pages and disable all alerts
8. In the Tab “Content” Disabling Pop-Ups
9. Tab In the “Privacy” all options off History
10. In the Tab “Security” Security Options unselect and “Settings …” disable alerts
11. In the Tab “Advanced” deactivate “automatic transfer” of the subtab “General” and turn off alerts and search engines the tab “Updates”
12. Go to “Tools-> Extensions” and install Firebug, and ScreenGrab Selenium IDE
13. In the address bar type “about: config”
14. Create logic input (boolean) “extensions.update.notifyUser” -> false
15. Create logic input (boolean) “extensions.newAddons” -> false
16. Modify the entry “network.automatic-ntlm-auth.trusted-uris” and enter the domain of the server where we want to test the Web application
17. Modify the entry “network.ntlm.send-lm-response” and give it a value of “true”
At this point we have properly configured Firefox profile.
Selenium configuration to take your Firefox profile created
Modify the batch file that runs Selenium (in the root of WebTest) and include the following parameter after the call to the JAR file: “-firefoxProfileTemplate C:\webtest\WebTest-FFPROFILE-IWA” (change C:\webtest\WebTest-FFPROFILE-IWA with the foldername into which you saved the newly created Firefox profile.
Done, your tests now should run under Windows Integrated Authentication.
I hope to serve you at some point if you run into this problem. 
Is this PMI Agile perspective?
Sep 1st
In the August edition of “PM Network” a short presentation about what is and whether to adopt Agile was published. It touches on several of the principles and suggested (in a somewhat biased way in my opinion) the situations where they apply or situations where they don’t. Anyone interested in seeing it, can do it here::

But the interesting part is the response posted by some Agile Folks Enjoy:
Scrum in Rosario City!
Jul 27th
During a new visit to the beautiful riverside city, this time supported by Fundación Libertad, I have the chance to chat a few hours about the meaning of Scrum in order to get a little bit closer to Agile.
We were fortunate to enjoy a cool winter morning, in a high floor of a building in downtown that offers a breathtaking view of the river Paraná. Gorgeous!
At the beginning, we held a dynamic called “tribes” through which we identified different groups of professionals and their knowledge and use of Agile methodologies in their projects (it’s amazing how this kind of exercise always works, whatever the context or group of persons).
Later on, we started talking about the Principles, the Agile Manifesto, User Stories, Sprints, Product Backlog, Release Plan, Task Board, Daily Standup Meetings, Retrospectives…, trying to understand what makes Agile Methodologies so effective when talking about improving the quality delivered to the customer and the practices of our daily work.
Even though many people are reluctact about these methodolgies and find them strongly contrasting with what they´ve learnt so far, there are many others who are positively interested and look forward both to learning more about Agile and applying it at work. The mere act of participating in this experience is a great way to do it!
Here I post the presentation we used (in spanish):
Hope to see you again soon, Rosario!
Procrastination
Mar 28th
By prioritizing the stories in the backlog we’re supposed to do it by business value or ROI (value / cost). I like to also add the risk inherent in the user story and use it as a factor to decide on prioritization.
Said in a different way, the group of stories with greater ROI can be divided into more risky stories and less risky stories. In particular I prefer to first address those at high risk because I see agile methodologies a great tool for risk mitigation. If the risky stories are left or postponed for a later time, we wouldn’t be mitigated any risks.
Just thinking out loud because of a procrastination video I saw on YouTube.
Procrastination
Procrastination refers to the counterproductive deferment of actions or tasks to a later time. Psychologists often cite such behavior as a mechanism for coping with the anxiety associated with starting or completing any task or decision.[1] There are three criteria for a behavior to be classified as procrastination: it must be counterproductive, needless, and delaying.[2]
Procrastination may result in stress, a sense of guilt and crisis, severe loss of personal productivity, as well as societal disapproval for not meeting responsibilities or commitments. These feelings combined may promote further procrastination. While it is regarded as normal for people to procrastinate to some degree, it becomes a problem when it impedes normal functioning. Chronic procrastination may be a sign of an underlying psychological disorder.

Bigger procrastination examples are those deep analysis and design phases of traditional project management, also known as Analysis-Paralysis, but this is a topic for another post. (procrastinating)… 
Agile in Action! – March 2010 – Review
Mar 28th
From March-16th trough March-26th the workshop named Agile en Acción! took place in Buenos Aires City.
This edition was delivered to 15 participants, who through a serie of workshops based on real requierements created EPICs and User Stories, estimated and prioritized them, created the Product Backlog, defined Velocity, put together the Release Plan, and ended with a series of retrospective execices.
There was a great dynamic between the participants and between the teams that were built. We all have fun during those 4 days. I took some photos that you can access here: http://bit.ly/alQC2j
Greetings!
There will be a new Agile in Action! in April-2010: http://bit.ly/agile-en-accion–abril-2010
