Automated Testing of REST Services

Hello guys, I have been busy these days, for this reason I am a little late.

In my new project I have been working with web-services and I think this could be useful if you want to do automated tests of Rest Services. I summarise the post, because I don’t agree 100 % with this guy. He says that if you are testing the web service you don’t need to test the client, but the behaviours are different, so you still need test the clients, not the data but the behaviour.

Integration tests were more complex task at that time because such tests imply usage of some mock frameworks. Since an API is consumed by different clients (smartphones, desktops…), make sense to gather a group of tests which check a common logic for all types of clients and to highlight the client-specific test scenarios to focus on a client specific logic. The logic works with data which was already tested in API layer. Such approach gives us an amazing testing strategy. We just need to pay all attention to a UI and some specific features instead in different clients: mobile, web, etc. BUT we still need test different clients, the difference is: We don’t need to test the data, just the behaviour of the client 🙂


Automated Testing of REST-services

In my experience I have been testing REST-services manual and automated. The framework that we are using here is Abdera to generate the xml and HTTP Client to post the xml on the server. But this guy is using REST-assured library . It is very easy to use and it works well with the most popular java testing frameworks such as TestNG, JUnit and Hamcrest.

 public void getLandLaordTest() {
 .pathParam("id", "DoYlvMXN")
 .body("firstName", equalTo("Sam"))
 .body("trusted", equalTo(false));


Ok, guys it is this, see you next week !


How to read the text from an Alert(ios) in calabash ?

Hi guys,

It’s been a long time that I don’t post anything about calabash and mobile automation, but I found this in my favorites and I realized that could be useful for someone. I am not sure if doesn’t exist another way to read a text inside an Alert, but this is one of the solutions:

Example of step:

Then I see a popup with latitude 10 and longitude 20



Then /^I see a popup with latitude (\d+) and longitude (\d+)$/ do |lat, lon| 
  msg = "Latitude:#{lat}\nLongitude:#{lon}" 
  should_see_alert_with_text msg 


def should_see_alert_with_text (text) 
wait_poll(:until_exists => 'alertView', :timeout => 5) do
  actual = query('alertView child label', :text).first
  unless actual.eql? text 
    screenshot_and_raise "should see alert view with message '#{text}' 
but found '#{actual}'" 


Thank you ! See you 🙂



How to update a xml with shell script ?

Hey guys, do you remember the script to create xml with shell script ?

Today I will post an example of shell script to update tags in xml file. I used the script in the bottom link as base.

This is the xml that I used as example:

<?xml version="1.0" encoding="ISO-8859-1"?>
 <from>Br Bank</from>
 <message>We are pleased to inform you that the above amount was transferred 
to your bank account</message>


And this is the script:

# !/bin/bash
# Written by rafazzevedo

# Uncomment this if you want to use parameters given by #the user and change the variables for the parameters #position like: $1 is the first parameter, $2 is the #second. Instead of tag, xml_file...
# if [ $# -ne 3 ]; then
# echo 1>&2 "Please, use the parameters file, tag and new value."
# exit 127
# fi


# We will create a temporary file, just to not modify directly the original one.

# This space is just to identify the end of the xml.
echo " ">> $xml_file

# Extracting the value from the <$tag> element
tag_value=$(grep "<$tag>.*<.$tag>" $xml_file | sed -e "s/^.*<$tag/<$tag/" | cut -f2 -d">"| cut -f1 -d"<")

echo "Found tag value $tag_value..."

# Replacing element value with $new_value
sed -e "s/<$tag>$tag_value<\/$tag>/<$tag>$new_value<\/$tag>/g" $xml_file > $temporary

echo "Changing $tag to $new_value..."

# Updating the changes to the original file ($xml_file)
chmod 666 $xml_file
mv $temporary $xml_file

Thank you guys ! See you soon 🙂


Gherkin BDD comparison

Hi guys, I will post a research about the BDD engines, it is a bit old (2012), but despite this I found very interesting. I have summarised the relevant informations. The actual language to write tests with BDD is called Gherkin. And it has different implementations adopted to different programming language, the most famous:

Cucumber for Ruby

JBehave for Java

NBehave and SpecFlow for C#

Freshen for Python Behat for PHP

All of them have some common set of supported features but there’re some restrictions and abilities specific to the actual engine. So, we will collect useful features for each listed above engine and present it in some comparable form. Key features to be mentioned are:

  • Documentation availability
  • Flexibility in passing parameters
  • Auto-complete
  • Steps, scenario and feature scoping
  • Complex steps
  • Hooks and pre-conditions
  • Binding to code
  • Formatting flexibility
  • Built-in reports
  • Input data sources support
Grade Criteria
0 No support at all
1 Functionality exists but with serious restrictions
2 Major functionality exists
3 Full-featured support

Documentation Availability

  • Cucumber:
    • Cucumber group on LinkedIn – quite populated place with big number of active discussions
    • Cukes Tutorial Site
  • Freshen – honestly speaking I didn’t find any specialized resourse dedicated to freshen only. Most likely it can be discussed in the more general forums dedicated to BDD in general.
  • JBehave:
  • SpecFlow:
  • Behat:

With this sources to look the documentation of each engine, we can evaluate the criteria and the grades:

1 Documentation is available in general (it makes grade 1 at once)
2 Every feature is described and has examples (if it fits it makes grade 2)
3 There’re additional well-grown resources (forums, blogs, user groups) where we can find additional information about the engine

At the end we have:

Engine Documentation availability
Cucumber 3
Freshen 2
JBehave 3
NBehave 1
SpecFlow 3
Behat 3

Engine Auto-complete support
Cucumber 1

Sublime and BDD

A simple guide about how to write formatted BDD features in Sublime. – Download what you want in Package Control. If you don’t have the package control in your sublime, follow these steps: – Open the console:

ctrl ` shortcut

– If your sublime is 2:

import urllib2,os,hashlib; h = 'eb2297e1a458f27d836c04bb0cbaf282' + 'd0e7a3098092775ccb37ca9d6b2e4b7d'; pf = 'Package Control.sublime-package'; ipp = sublime.installed_packages_path(); os.makedirs( ipp ) if not os.path.exists(ipp) else None; urllib2.install_opener( urllib2.build_opener( urllib2.ProxyHandler()) ); by = urllib2.urlopen( '' + pf.replace(' ', '%20')).read(); dh = hashlib.sha256(by).hexdigest(); open( os.path.join( ipp, pf), 'wb' ).write(by) if dh == h else None; print('Error validating download (got %s instead of %s), please try manual install' % (dh, h) if dh != h else 'Please restart Sublime Text to finish installation')

– If your sublime is 3:

import urllib.request,os,hashlib; h = 'eb2297e1a458f27d836c04bb0cbaf282' + 'd0e7a3098092775ccb37ca9d6b2e4b7d'; pf = 'Package Control.sublime-package'; ipp = sublime.installed_packages_path(); urllib.request.install_opener( urllib.request.build_opener( urllib.request.ProxyHandler()) ); by = urllib.request.urlopen( '' + pf.replace(' ', '%20')).read(); dh = hashlib.sha256(by).hexdigest(); print('Error validating download (got %s instead of %s), please try manual install' % (dh, h)) if dh != h else open(os.path.join( ipp, pf), 'wb' ).write(by)

– Hit Enter and restart the sublime after downloaded the package.

  How to install Packages from Package Control ?

– ‘Command+Shift+P’ – Type ‘Install Package’ and enter

– Choose the package as :


Gherkin[Cucumber] Formatter


Behat Snippets

How to use ?

You can try any of these commands to generate respective file.

– ‘Command+Shift+P’ – Type: ‘Gherkin’

– ‘Command+Shift+P’ – Type: ‘Feature’

– ‘Command+Shift+P’ – Type: ‘Scenario’ or ‘Scenario Outline’

– ‘Command+Shift+P’ – Type: ‘Example’

  If you want some snippet of Given/When/Then/etc, you can use the command  ‘Command+Shift+P’ – Type: ‘Given’
