Why I keep badgering on about Web Testing..

Lately I've become somewhat obsessed with testing. A specific kind of testing. I'm not quite sure about the term right now, but it's close to system testing, or maybe user testing. Ye know, that kind of black-box testing that makes sure your stuff works from the user's perspective. In web applications (of which I probably do about 90% of the time) they happen to blend in with web tests.

I suppose it started off with last autumn when I put some thoughts on this into my lightning talk at the Smidig 2007 conference. Well, it actually started all the way back in 2006 when I did a lightning talk about Selenium in XP-meetup based on my experiences with Selenium vs. gargantuan use-case descriptions in a project (see slides).



A few months ago I was down visiting a friend in Bonn, Germany. He works for this CMS-vendor/host called WebFactory. I offered him to drop by their workplace and do a quick demo on Selenium, as I figured they're (a) probably doing web applications, and (b) they're probably not doing web testing (in the automated figure o' speech).

Strictly speaking, I didn't actually do the demo; I had my friend do the demo instead. I took some time in advance to teach him how, and naturally he made a much better point of how to use the tool in their shop than I could. Neat sales trick, eh?

Anyhow, one of the guys' impression was "We had no idea it was that easy!", which is the usual response triggered by showing off Selenium. The 10 minute demo eloped into hours of interesting discussion on all things web, testing, JavaScript, Comet, etc, and the whole thing sort of re-invigorated my feeling of that people still do not know enough about web testing, and the world would be a bit better off if more people knew about it.


If you don't know what it is, there it is (in its simplest sense). A Firefox plugin that records your browsing instructions and can replay them later on a lot faster than you can with mouse and keyboard.

A few weeks later I went on to do a 30-minute session on web testing for my current customer's Java developers. Some days later on I held a 2 hour guest lecture in the University of Oslo's open source course.

I figured, hey, I'm starting to get quite good at presenting this web testing stuff. So I piggy-backed my own effort when writing an abstract submitted to this year's JavaZone conference. I have to admit it's not the most academical subject I would've liked to talk about. But I still see people (a) doing web applications, and (b) not automating their tests. I think it's good talk material because it is:

  • Simple and easy to convey
  • Really useful
  • (and I'm not trying to push any proprietary stuff here, I'm not even a Selenium committer)

So that's why I keep badgering on about Selenium and web testing. I could write page after page on web testing, but for now, if you're interested, take a look at the links in this post and take Selenium for a spin if you haven't already (the new 1.0 beta version is pretty sweet). And give me a shout on what you would have me write about next time. For instance:

* How web tests fit into the bigger picture (testing strategies and all that)
* Why I exaggerated when I once said Selenium tests can replace use-cases
* Why manual testing is still important
* Putting Selenium tests into a Continous Integration server (i.e. expanding my last post on the subject)

Encrypting and Decrypting with Spring

I was recently working with protecting some sensitive data in a typical Java application with a database underneath. We convert the data on its way out of the application using Spring Security Crypto Utilities. It "was decided" that we'd be doing AES with a key-length of 256, and this just happens to be the kind of encryption Spring crypto does out of the box. Sweet!

The big aber is that whatever JRE is running the application has to be patched with Oracle's JCE in order to do 256 bits. It's a fascinating story, the short version being that U.S. companies are restricted from exporting various encryption algorithms to certain countries, and some countries are restricted from importing them.

Once I had patched my JRE with the JCE, I found it fascinating how straight forward it was to encrypt and decrypt using the Spring Encryptors. So just for fun at the weekend, I threw together a little desktop app that will encrypt and decrypt stuff for the given password and sa…

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 operating on many repositories at the same time.

Always use git-svn with --prefix

TLDR: I've recently been forced back into using git-svn, and while I was at it, I noticed that git-svn generally behaves a lot better when it is initialized using the --prefix option.

Frankly, I can't see any reason why you would ever want to use git-svn without --prefix. It even added some major simplifications to my old git-svn mirror setup.

Update: Some of the advantages of this solution will disappear in newer versions of Git.

For example, make a standard-layout svn clone:

$ git svn clone -s https://svn.company.com/repos/project-foo/

You'll get this .git/config:

[svn-remote "svn"]
        url = https://svn.company.com/repos/
        fetch = project-foo/trunk:refs/remotes/trunk
        branches = project-foo/branches/*:refs/remotes/*
        tags = project-foo/tags/*:refs/remotes/tags/*

And the remote branches looks like this (git branch -a):
    remotes/trunk
    remotes/feat-bar

(Compared to regular remote branches, they look very odd because there is no remote name i…

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 without the…

Automating Computer Setup with Boxen

I just finished setting up a new laptop at work, and in doing so I revamped my personal computer automation quite a bit. I set up Boxen for installing software, and I improved my handling of dot-files using vcsh, which I'll cover in the next blog-post after this one.

Since it's a Mac, it doesn't come with any reasonable package manager built in. A lot of people get along with a combination of homebrew or MacPorts plus manual installs, but this time I took it a step further and decided to install all the "desktop" tools like VLC and Spotify using GitHub's Boxen:

  include vlc
  include cyberduck
  include pgadmin3
  include spotify
  include jumpcut
  include googledrive
  include virtualbox

If the above excerpt looks like Puppet to you, it's because it is. The nice thing about this is that I can apply the same puppet scripts on my Ubuntu machines as well. Boxen is Mac-specific, Puppet is not.

It was a little weird to get started with Boxen, as you're offered…
