Automating and Testing a REST API
A Case study in REST API Testing and Automating using: Java, RestAssured, Tracks, Postman, cURL and HTTP Proxies
This 200+ page e-book documents a case study of testing and automating a REST API based application.
It covers interactive testing of the application through the GUI, and via cURL and HTTP Proxies.
And automating with Java and REST-assured.
Comprehensively documented, with full source code available, you’re sure to learn something new.
This is the support page for the book with links to the source, tools and the free supporting videos mentioned in the text.

- 20170804 - update, Bitnami have discontinued their VM and workaround for Turnkey Icon isses
Tracks is an open source application written in Ruby on Rails which implements the David Allen “Getting Things Done” time management methodology.
My current recommended approach is to use Docker,
- docker instructions (see video below)
- getontracks.org/downloads aboutbitnamitracks
- Bitnami Tracks Installer
Virtual Machine Software
Prebuild Tracks Virtual Machines
- Turnkey Tracks
- Bitnami Tracks
- if you are experiencing issues with GUI icons then see this workaround
You can install cURL on windows using:
- one click installer from http://www.confusedbycode.com/curl/
- chocolatey using
choco install curlhttps://chocolatey.org/
- the official site https://curl.haxx.se/ (use the download wizard https://curl.haxx.se/dlwiz/)
see the videos below for each of these installation approaches
The easiest HTTP Proxies to use are:
You could also use:
You can find information about
- REST Wikipedia page
- An overview REST tutorial at restapitutorial.com
- Roy Fielding defined REST in his Ph.D. Thesis, you can read it as a .pdf
REST API Tools
Tools not used in the case study:
- Insomnia.rest cross platform desktop REST client
REST Java API Libraries
The case study uses REST-assured:
Other libraries are available:
Lists of APIs to Experiment With
Fake APIs - i.e. these are api endpoints which serve canned data and responses
- https://swapi.dev/ - (GET requests only)
Lists of APIs (primarily of use to see different api styles and approaches)
APIs designed for testing against
The source code for all the Java code used to automate Tracks as part of the case study is available on Github
There is a video below showing how to install and use the source code.
The Postman Collection for the case study is available in the above source code and shared on the Postman site:
- From Github
- From Postman - getpostman.com/collections/b9e81b009bfd21ec5e83
- As a bit.ly - bit.ly/2iPaxgj
I created supporting videos for some of the chapters and sections in the book. These make most sense when read in conjunction with the book but offer a visual insight into tools used which the book can’t cover quite as well.

Installing Tracks Via Docker
This is easy to install using Docker and this video shows the process in action.
- You need to setup a Docker account at https://docker.com
- follow the instructions on the hub page
docker pull staannoe/tracks docker run -d --name=tracks -p 80:80 staannoe/tracks
Then visit localhost:80, create an admin account.

Installing Tracks Using a Virtual Machine
Installing Tracks to a VM using Turnkey.
The last time I used the Turnkey VM I used the VMWare Player 12 and used the following steps:
- download the VM (.ova file)
- using vmware workstation 12 player
- “Open a Virtual Machine” - choose the .ova file
- … vmware player spends some time importing the VM…
- run VM
- change password for root and MySql e.g. Pa55Word
- skip hub and password setup
- skup security updates
- change VM to use HOST-only private network or Bridged Adapter
- select to use DHCP for network config
- note the IP address shown in the dialog e.g. 192.168.222.129
- tracks should be running on this IP address visit http://

Other Blog posts and information you might want to read related to the material in the book, I include a lot of extra references in the book, but these were found after publication and I did not want to keep adding more links into the book, so I added them here instead, I also included a few from the book:
Blog Posts and Sites:
- My Basic and Advanced REST API Workshop material this uses a different target application with different code examples.
- Bas Dijkstra’s Open Source API Workshops
- Testing REST Endpoints Using REST Assured by Kostis Kapelonis
- Mark Winteringham has a lot of useful Postman and REST information on his site here are some examples:

Paperback edition currently in proof creation and review mode. Will be the same as the 2017/07/03 release.
On 4th August 2017 I was told that Bitnami had discontinued the Tracks VM and self contained install.
This is unfortunate as I found it the most reliable and easiest way of getting started. Turnkey is now the simplest way of getting started.
I emailed Bitnami, just in case they could reinstate the installs but on 8th August I learned that the installs would not be reinstated. I suspect the following links will forever remain ‘discontinued’.
You should probably use Turnkey Tracks installers and VMs (but see the additional information below).
Using Bitnami VMs
You can still use Bitnami VMs but you have to install Tracks yourself. The following instructions are the steps I took to install Tracks into the Bitnami Ruby Infrastructure VM.
- make sure that the VM can access the outside world e.g.
curl http://eviltester.comprior to following any steps
- I switched off my local firewall for 30 mins while doing this (I haven’t added VMWare to my firewall since I changed my local firewall software)
- follow install instructions for tracks
- make a note of the ip address on the start screen 192.168.199.129
- if you miss the IP Address then when you are logged in you can type the following to show it
ip addr show
- if you miss the IP Address then when you are logged in you can type the following to show it
- following the install instructions from tracks
sudo gem install bundler
git clone https://github.com/TracksApp/tracks.git
bundle install --without development test
cp database.yml.tmpl database.yml
cp site.yml.tmpl site.yml
database.ymlto use the sqlite3 lines
- don’t really care about the security so I didn’t amend site.yml
cd ..to move to the
- precompile the assets
bundle exec rake db:migrate RAILS_ENV=production
- open port 3000 in VM
- I change VM to local network (Host-only) to avoid firewall issues 192.168.245.128
- start app with
bundle exec rails server -e production -b 0.0.0.0 -p 3000
-b 0.0.0.0to map to external facing ‘localhost’
Turnkey Icon Workarounds
Stas Wasserman was kind enough to describe some additional information and workarounds on the Turnkey install:
- The option of using Turnkey is available, with a minor, but quite annoying issue in Tracks UI.
- (I know, the problem is not related to API, but it makes Tracks UI exploration a bit puzzling)
- This issue is with missing icons in Tracks from Turnkey. For example, the start and the edit icons are missing for existing actions in a project (you can see the missing resources error in a browser dev console).
- The issue is mentioned here: turnkeylinux.org/forum/support/20130805/missing-icons-latest-tracks-121-appliance
- The proposed workaround worked for me with a minor tweak (added RAILS_ENV=production , as suggested on the Tracks GitHub page : github.com/TracksApp/tracks/blob/v2.3.0/doc/installation.md:
bundle exec rake assets:precompile RAILS_ENV=production
- You need to run this in Linux command line (or SSH) on the VM.
- Then, after restarting my virtual machine, I have got the icons after login into Tracks.
- Hope this helps, in case other students will face a similar issue.
