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…

Considerations for JavaScript in Modern (2013) Java/Maven Projects

Disclaimer: I'm a Java developer, not a JavaScript developer. This is just what I've picked up the last years plus a little research the last days. It's just a snapshot of my current knowledge and opinions on the day of writing, apt to change over the next weeks/months.

We've gone all modern in our web applications, doing MVC on the client side with AngularJS or Ember, building single-page webapps with REST backends. But how are we managing the growing amount of JavaScript in our application?
You ain't in Kansas anymore So far we've just been doing half-random stuff. We download some version of a library and throw it into our src/main/webapp/js/lib, or we use it from a CDN, which may be down or unreachable when we want to use the application..

Some times the JS is minified, other times it's not. Some times we name the file with version number, other times without. Some times we get the latest library of master branch and name it with the commit-id in the fi…

Microsoft ups their Git efforts another notch

This week Microsoft announced first class Git support embedded in the coming version of Visual Studio.

Now, it's not completely shocking. We could have seen it coming since Microsoft started offering Git repos on CodePlex, and more recently offering a Git client for TFS. In any case, these are some big news. Scott Hanselman weighs on some features and some more background here.

For those who are a bit unaware of what the Git situation on Windows looks like these days, I've dotted down these notes:
Some explanation on these:

msysGit has long been The Way to use Git on Windows. It's basically a port of Git itself, so it's a command-line tool.GitExtensions (includes Visual Studio integration), TortoiseGit, Git Shell, posh-git and most other tools are powered by msysGit.libgit2 is a native library for doing Git stuff. It is developed completely separate from Git itself. The above tools could (and should) probably use libgit2 instead of hooking onto and around msysGit.Github…
