Expose your test reports

I started off this post with the title "Our Quest for Agility" but it kind of trailed off into being about our latest customer-dashboard tool. I'll do another post about our agile quest later.

The Greenback project

Before the summer, I was issued with the task of setting up a customer-management portfolio tool, which I named Greenback (as in, money, because that's what we want from our customers). The first goal was to provide our customer-managers with an overview of which customers exists, where they are installed, which applications they are running and other configuration details. Greenback is basically a web application with a big table with our customers and some filters to see the customers for a single manager, or with a particular configuration. Our customer-managers can also edit, add and comment all the entries, naturally.

We have a rather large portfolio of customers (200+), and each of these are hosted with their own application of our software. Through development, we strive to keep all these customers in a working state for testing, but it's not always easy. Developing a feature for one customer will some times break the functionality in many others. Maintaining the test-data for every customer is also a challenge.

Automatic deployment and web testing


At the same time, I started pondering about how we could continuously test all these customers' applications. First thing, we got automatic deployment set up. I then made a simple web-test that basically tried loading the front page of a customer's application on the nightly deployment. I then looped this test over every customer, every morning (in our CI-environment/Hudson).

At the same time, we made a big overhaul of our test data to get every customer's test-data into working condition. It didn't take long before the first customer's application broke again on the nightly build. I started wondering: How can we keep every customer in a working state? We need some kind of proper reporting that people will respond to, because scrolling through a console output to see which applications are broken simply does not work over time.

Synergy

Then it occurred to me. Why not report the results of the web-tests back to the Greenback overview? I put together a little call-back at the end of our customer-test that wrote the result into Greenback, merely as a traffic light: Red meant that the setup scripts for the customer were not working at all, yellow meant that the application was working, but the front page wasn't working properly, and green meant everything is OK. I then made a new column in our customer table with the color of the test-result, and a link to the nightly deployment for those who want to investigate any problems, or test a particular application.

Later on, I also added a little test-history so customer-managers and developers alike could track when a certain application stopped working (we can't always drop what we're doing and fix test data every time we see a red light). Next in line is to produce a feed that people can subscribe to, to see any changes in the state of applications.

The great advantage of this is that the customer-managers themselves can take ownership in making sure that their applications are working. It was all in all pretty easy to set up (a few weeks of work, all in all), and I hope others with similar needs will find some inspiration in this.

Open source CMS evaluations

I have now seen three more or less serious open source CMS reviews. First guy to hit the field was Matt Raible ( 1 2 3 4 ), ending up with Drupal , Joomla , Magnolia , OpenCms and MeshCMS being runner-ups. Then there is OpenAdvantage that tries out a handful ( Drupal , Exponent CMS , Lenya , Mambo , and Silva ), including Plone which they use for their own site (funny/annoying that the entire site has no RSS-feeds, nor is it possible to comment on the articles), following Matt's approach by exluding many CMS that seem not to fit the criteria. It is somewhat strange that OpenAdvantage cuts away Magnolia because it "Requires J2EE server; difficult to install and configure; more of a framework than CMS", and proceed to include Apache Lenya in the full evaluation. Magnolia does not require a J2EE server. It runs on Tomcat just like Lenya does (maybe it's an idea to bundle Magnolia with Jetty to make it seem more lightweight). I'm still sure that OpenAdvant

Managing dot-files with vcsh and myrepos

Say I want to get my dot-files out on a new computer. Here's what I do: # install vcsh & myrepos via apt/brew/etc vcsh clone https://github.com/tfnico/config-mr.git mr mr update Done! All dot-files are ready to use and in place. No deploy command, no linking up symlinks to the files . No checking/out in my entire home directory as a Git repository. Yet, all my dot-files are neatly kept in fine-grained repositories, and any changes I make are immediately ready to be committed: config-atom.git     -> ~/.atom/* config-mr.git     -> ~/.mrconfig     -> ~/.config/mr/* config-tmuxinator.git       -> ~/.tmuxinator/* config-vim.git     -> ~/.vimrc     -> ~/.vim/* config-bin.git        -> ~/bin/* config-git.git               -> ~/.gitconfig config-tmux.git       -> ~/.tmux.conf     config-zsh.git     -> ~/.zshrc How can this be? The key here is to use vcsh to keep track of your dot-files, and its partner myrepos/mr for o

Leaving eyeo

Thirteen blog posts later, this one notes my departure from eyeo after 4 years and 3 months. I joined eyeo around the headcount of 80 employees, and now I think there's just over 250 people there. My role coming in was as operations manager, doing a mix of infrastructure engineering and technical project management. I later on took on organizational development to help the company deal with its growing pains . We introduced cross-functional teams, departments (kind of like guilds), new leadership structures, goal-setting frameworks, onboarding processes and career frameworks.  And all of this in a rapidly growing distributed company. I'm proud and happy that for a long time I knew every employee by name and got to meet every single new-hire through training them on company structure and processes.  At some point, we had enough experienced leaders and organizational developers that I could zoom back in on working in one team, consulting them on  Git and continuous integration

Joining eyeo: A Year in Review

It's been well over a year since I  joined eyeo . And 'tis the season for yearly reviews, so... It's been pretty wild. So many times I thought "this stuff really deserves a bloggin", but then it was too inviting to grab onto the next thing and get that rolling. Instead of taking a deep dive into some topic already, I want to scan through that year in review and think for myself, what were the big things, the important things, the things I achieved, and the things I learned. And then later on, if I ever get around to it, grab one of these topics and elaborate in a dedicated blog-post. Like a bucket-list of the blog posts that I should have written. Here goes: How given no other structures, silos will grow by themselves This was my initial shock after joining the company. Only a few years after taking off as a startup, the hedges began growing, seemingly almost by themselves, and against the will of the founders. I've worked in silos, and in companies wit

Using Voice-Chat for Gamers in Distributed Teams

This is a post going into the usefulness of live voice-chat tools in distributed teams. If you've ever seen the Leeeeeroooooyy Jeeeenkiiins video of World of Warcraft fame, you've heard this kind of tool in action. It's how the participants in the video are speaking with each other - this is not a feature built into the World of Warcraft game - it's a separate team-oriented VoIP software, and it's all about letting gamers communicate orally while gaming.  Since these tools are for gamers, they have to be fast (low latency) light (as not to steal CPU-cycles from heavy games graphics)  moderate in bandwidth usage (as not to affect the game server connection) There are several options around: TeamSpeak , Ventrilo , more recently the massively grown Discord , and finally Mumble , which is the open-source alternative of the gang. A few years ago, when I joined eyeo (a distributed company), several of the operations team were avid gamers, and had a TeamSp
