Integrate ServerSpec, Testinfra and ZAP with CentOS 7 Minimal

We already know how to setup tests with ServerSpec and Testinfra in Quick start for ServerSpec and Testinfra, also comparison of them and Quick start for integrating ZAP into CI. Now, let’s see how to integrate them with CentOS 7 Minimal.


  1. Install CentOS 7 Minimal successfully with root user setup and login.

  2. Enable network on CentOS 7 Minimal following this article.

    The detailed steps are:

    1) Open Network Manager through nmtui;

    2) Choose “Edit connection” and press Enter (Use TAB button for choosing options);

    3) Choose your network interfaces and click “Edit”;

    4) Choose “Automatic” in “IPv4 CONFIGURATION” and check “Automatically connect” checkbox, then press “OK” to quit from Network Manager;

    5) Reset network services through service network restart.

  3. Adjust the screen resolution following this article.

    The detailed steps are:

    1) Edit GRUB file: vi /etc/default/grub

    2) Append vga=792 to the line GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet,

    and you will have GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet vga=792;

    Check for the detailed GRUB VGA Modes, or scroll down to the bottom of this article.

    3) Add this change to GRUB configuration: grub2-mkconfig -o /boot/grub2/grub.cfg

    4) Reboot to take effect: reboot.

  4. Add a Yum source and update.

    yum install epel-release
    yum -y update
  5. Configure ssh key to connect server easily.

    • Generate ssh key: ssh-keygen -t rsa
    • Copy ssh public key to server: ssh-copy-id -i ~/.ssh/ username@server
    • Add following lines to ~/.ssh/config.

      Host server
      User username

Quick start for ServerSpec:

  1. Install Ruby.

    yum install ruby

  2. Install RubyGems.

    yum install rubygems

  3. Install Rake.

    gem install rake

  4. Install ServerSpec.

    gem install serverspec

  5. Initial ServerSpec folder with basic settings. Please note the server will be set in this step.


  6. Write and run the ServerSpec script according to its API document.

    You can reference the script here.

    Using rake spec under the test folder to run and check the result.

  7. To run specific test rather than the entire test suite.

    Using rake spec spec/host_server/sample_spec.rb under the test folder to run and check the result.

Quick Start for Testinfra:

  1. Python 2.7 is installed by default, so we just need to install Pip.

    -y install python-pip
    pip install --upgrade pip
  2. Install Testinfra and Paramiko.

    pip install testinfra
    pip install paramiko

  3. Write and run the Testinfra script according to its API document.

    You can reference the script here.

    Using testinfra to run and check the result.

  4. Some useful arguments we can use to make the test result more clear.

    Instead of using testinfra directly, we can add some arguments, such as -q, -s, --disable-warnings and --junit-xml.

    • The argument -q will run Testinfra in quiet mode, with less info exposed
    • The argument -s will let Testinfra capture No pre-test info
    • The argument --disable-warnings will disable warnings during Testinfra runs
    • The argument --junit-xml will export Testinfra test result into a xml file

    After adding those arguments, the command should be look like testinfra -q -s --disable-warnings --junit-xml=report.xml

  5. Now we can run Testinfra against the server using testinfra -q -s --disable-warnings --ssh-config=/Path/to/ssh/config --hosts=server --junit-xml=report.xml.

Quick Start for ZAP:

  1. Install JDK.

    yum install java-1.8.0-openjdk*

  2. Download ZAP installation script.


  3. Change permission of the installation script and execute it.

    chmod 777
  4. Install required libraries.

    1) Install Selenium-WebDriver

    gem install selenium-webdriver

    2) Install IO

    gem install io

    3) Install Rest-Client

    yum install gcc-c++
    gem install rest-client

    4) Install RSpec

    gem install rspec

    5) Install and configure the headless Firefox

    yum -y install firefox Xvfb libXfont Xorg
    yum -y groupinstall "X Window System" "Desktop" "Fonts" "General Purpose Desktop"
    Xvfb :99 -ac -screen 0 1280x1024x24 &
    export DISPLAY=:99

    6) Download and setup geckodriver.

    tar -xvzf geckodriver-v0.18.0-linux64.tar.gz
    mv geckodriver /usr/lib64

    7) Add following lines to ~/.bash_profile.


    And run source ~/.bash_profile.

    8) Alternatively, we can use Chromedriver:

    i) Create a file called /etc/yum.repos.d/google-chrome.repo and add the following lines of code to it.


    ii) Check whether the latest version available from the Google�s own repository using yum info google-chrome-stable

    iii) Update yum using ‘yum update’

    ix) Install Chrome using yum install google-chrome-stable unzip

    x) Download Chromedriver using wget

    xi) Unzip Chromedriver using unzip

    xii) Move Chromedriver to a place in $PATH using mv chromedriver bin/

  5. Using ruby add_assertions_to_check_zap_result.rb to run and check the result.

    You can reference the script here.
