Performance measurement with PhantomJS and confess

PhantomJS and confess make it possible to measure your webapplication performance via command-line.



If your PhantomJS version >= 2.0, phantom.args is deprecated! “TypeError: undefined is not an object” You have to make a quick hack inside the confess.js file.

Run the performance measurement

Note: By default the results go to stdout, but you can pipe into a file!

Run your Python Selenium tests headless

This time i show you the headless testing with Selenium WebDriver and PhantomJS. This method can be used for example on continuous integration systems.

Install PhantomJS

Follow the documentation on PhantomJS website or as Mac OS X user simply use Mac Ports.

Create a tiny test script

Just create a instance of PhantomJS WebDriver and run you tests. That is all! 😉

Start with Python and Selenium WebDriver

This introduction should give you some hints about Python and Selenium WebDriver. I will use this in following tutorials as a base.


  • Python installed
  • pip (package manager) installed
  • Editor or IDE installed


As first step simply install or upgrade the Selenium package.

This is a fairly simple process. After the successful command execution you will have the Selenium WebDriver client library on your machine with all that is needed to create automated scripts.

The first script

Now start using the unittest library. The script comments help to describe the code.

Run Test

To run the test simple call your script.

Jenkins – Modern Status Plugin

Who the original symbols of Jenkins do not like, should try the Modern Status Plugin. The tiny plugin of Oliver Vinn provide a new and very cool set of icons for the continuous integration server. The installation is very simple!


This is a example of original icons:

jenkins original status icons

Open the Plugin Manager and search for “Modern Status Plugin”.

jenkins modern status plugin

After restart Jenkins the new iconset should be available and look like:

jenkins modern status

CSSLint with Grunt on Debian

This tutorial gives an tiny insight into CSSLint with Grunt on Debian. After that you should be able, to implement more Grunt tasks for your project.


As root or sudo user install needed packages

Check the installation.

Create a new project

As “normal” user create a new project and install the needed plugin.

If no problems occurred, the package.json file should look like:

Create a css folder and a css file with some mistakes like:

In the last step we create the Gruntfile.js

Thats all, now run just the command and see the results.

Geolocation and Python

There are a lot of different services where you can ask the Geolocation for IP and/or Domains. With python it is very easy to make requests on that APIs. As security tester you can use it on the discovery term.



Sass, Compass and Jenkins

This tutorial shows how Sass, Compass and Jenkins working together in very easy way. The goal is that Jenkins created the CSS from SCSS files.


  • Jenkins installed
  • Ruby installed


In first step we need to install Sass and Compass on the clients (Developer engines) and build server (Jenkins).

Now we create on one client the project.

Now add and edit some content to the files with your favorite editor and commit all to your repository. The content for the tutorial looks like this:

Okay… now lets go to Jenkins. Here we create a new “Freestyle Job” and configure the Source-Code-Management and insert the following command into “Execute Shell”

Thats it… after running the build into the workspace you should see the folder “css” and a file “style.css” the content should look like:
