Last weekend I attended TDC (The Developers Conference) 2011 in Florianópolis, in the south of Brazil. It was my first time in Florianópolis, but the weather was cloudy and cold, so I couldn’t check out one of the prettiest cities in Brazil :-( Bummer.

Putting the weather aside, TDC was great! Basically, there were many nice, easy-going people gathering together to talk about subjects like Java, SOA, Arduino, Testing, Agile and more. I had the chance to talk with skilled and experienced people, see different talks and catch up Guilherme Motta (@gfcmotta) from ThoughtWorks, who I have met in Porto Alegre in the beginning of this year. He gave an interesting talk about crowd testing using games as example, but varying with applications in different areas too.

It’s been a while since the last time I posted something here. The reason is that I have been busy fixing bugs in Jenkins TestLink Plug-in, TestLink, TestLink Java API, tap4j, Jenkins TAP Plug-in and other Open Source projects.

Recently I left Sysmap Solutions, where I was a consultant, to have my labor card signed by Lojas Riachuelo, a famous Brazilian fashion retailer (like C&A, Zara, H&M and so on), part of Guararapes group.

So I am still getting used to the new routine, new systems and be a employee rather than a consultant.

There are also two talks to come, one in a few days at TDC (The Developers Conference) 2011 in Florianópolis, and another one in the beginning of September at JCertif in Congo/Brazzaville. While I already bought the tickets and booked the hotel rooms, I still have to finish some slides and practical examples for both events.

I already have two draft posts that I am still writing. One about continuous integration and parallelism/concurrency, and another one about spell check in DocBook projects, specially if you are using Maven.

Today I had a new idea for a bioinformatics tool that is may be helpful for researchers and bioinformatics professionals. I will write about it as soon as I find some spare time, so stay tuned ;)

Time to get back to work!

Last month I attended the II Sao Paulo Perl Workshop, where I had the privilege of learning with the great talks performed by bryan d foy, Brad FitzPatrick and Larry Wall. For being a Java programmer, you can imagine how lost I was feeling there.

The first programming language that I had contact with was Perl. I was a 16 years old Slackware aficionado at that time, and was dying to have a web site with a guestbook . We did not have any cheap hosting services in Brazil that offered a PHP environment, but there were few companies that offered a free host with ads, and with Perl. I don’t remember which script I used, only that I found it in HotScripts.com and that it stored the guestbook entries in disk. Now, ten years after, here I am playing with Perl again! :-D

Well, what was my idea of Perl before the event? I thought it was an old programming language, very powerful, but over complicated. And what do I think of Perl now? I think it is an old programming language, very powerful, but may be complicated.

I have been playing with TAP for some time and even implemented a Java API to let TestNG, JUnit and other Test Frameworks to produce and consume TAP. TAP is a standard format for test output that first appeared with Perl 1 in 1987. It is human and machine readable, easy to be serialized, language independent and extensible¹ through the use of YAML.

Some days ago while I was designing a plug-in to show TAP test results in Jenkins I stumbled across a message in Jenkins dev-list where Max Magee and Nick Wiesmueller were discussing about a way of showing more details about the test executions. I thought that the TAP Plug-in would fit perfectly, until one of the users, Robert Collins, mentioned SubUnit.

Shame on me, but I hadn’t heard of SubUnit until that message. Max Magee and I exchanged some messages after that, talking about a initial design and analysis for the TAP Plug-in ². Here is the initial idea:

• The plug-in will be able to parse one or more test formats (maybe SubUnit, TAP and the formats available in xUnit?).
• The test results will be displayed the same way JUnit tests are displayed in Jenkins (I think Jenkins supports JUnit format by default, but you can use objects and create test results data, independently of the test framework that you are using).
• There will be a table containing the Test Name, Description and Status and an expandable section.
• Inside this expandable section will be available all the details about the test.
• In case there are images within the test details, they should be displayed as a lightbox gallery.³

Although I have worked with TAP and spent some good time writing the tap4j port for Java, I am not convinced it is the best solution for this issue yet. Hence I am posting this initial comparison between TAP and SubUnit hoping that more people will contribute with the design of this solution. My goal is not only having a super cool plug-in for Jenkins, but ease integration of test results in different tools and collaborate with both TAP and SubUnit. Another objective that I have in mind is improving the way that test results are displayed in Jenkins and enabling it to be an alternative for tools like Smolder, TestRepository or Tribunal. Because I believe the tasks done by these tools could be all done in my favorite CI Server, and it would increase the productivity of Build & Release professionals :-))
