Voice Driven Testing using Perfecto Mobile

Most of the applications today started supporting voice commands either it is a desktop or a mobile.More & more functionalities are being supported by voice commands.

Testing these functionalities is very difficult as it requires audio files which are hard to edit / maintain them whenever required. Perfecto has come up with a better way to test these functionalities.

Steps to test Voice Driven Functionalities:

1. Enter required text
2. Convert Text to Audio
3. Inject the generated Audio to application

Seamless Integration of Selenium + AutoIT

AutoIT is a freeware available to automate Windows GUI by simulating the combinations of mouse movements & key strokes. AutoIT has its own basic syntax, editor & control identification mechanism. However, to achieve the code level integration one can use 'AutoItX', packaged with AutoIT. This supports access to AutoIT functions using COM objects.

Extract Text & Images from PDF

Extracting text from PDF is not as simple as reading text from a text(.txt) file. One has to use suitable libraries to extract data from any pdf file. For example, Below code snippet shows one of the way to extract text or images from PDF file using Apache's PDFBox libraries.

Visual / UI Test Automation using Selenium and Applitools Eyes

Visual / UI Testing is a methodology for validating the multiple visual aspects of Websites, Mobile apps and Desktop apps across multiple browser, resolution and OS combinations.

Visual / UI Testing is very important these days as more and more applications are getting web enabled. (i.e more of the standalone applications are being converted into websites) & most of the websites are eyeing on 'Responsive Web Design' to create a single website across multiple resolutions.The mobile apps designed for a platform has to support multiple screen resolutions or devices.

This type of testing is usually performed manually. However, now you can automate these type of tests using different automation tools available in the market. One such automation tool is Applitools Eyes which has the advantage of validating visual aspects within the existing Selenium scripts.

JDBC-ODBC Bridge support in Java 8

JDBC-ODBC Bridge offered lot of flexibility in connecting a data source. Many had used this bridge to connect & query MS Excel / MS Access as a database. Starting from Java 8, Oracle has removed this feature. This created a major blocker for many to upgrade to new Java version & many applications which were built based on this have failed.

As an interim solution, one can build an extension from jdbc classes of previous java version & add it to Java 8 extensions.

Follow the below steps to enable the JDBC-ODBC Bridge support in Java 8.

Selenium 3 Impact & Changes

Selenium is out with new stable version - Selenium 3.0.1, and this blog would detail out changes & impact the new version of Selenium brings into automation testing. 

Selenium 3, is believed to have major changes in its implementation & quite a few changes to the existing automation.In Sel-3, the original Selenium Core is being taken off & replaced with the alternative implementation that’s backed by WebDriver. It means, Selenium RC users would run into issues & might need to tweak their scripts to support new implementation. However, for web driver users it is believed to be a simple drop-in upgrade.

Jenkins REST API / Remote API

Jenkins is a open source continuous integration tool written in Java.
It is a server-based system running in a servlet container such as Apache Tomcat. It supports SCM tools including AccuRev, CVS, Subversion, Git, Mercurial, Perforce, Clearcase and RTC, and can execute Apache Ant and Apache Maven based projects as well as arbitrary shell scripts and Windows batch commands.

Jenkins has provided the flexibility of accessing it through code by exposing REST based API.

Test SOAP Services using REST Assured API

REST Assured(RA) is a framework built on Java, developed to test the REST services. However we can test SOAP services too by forming the request in the below format.

RA has inbuilt support for multiple authentication like BASIC, OAuth, OAuth2, Form, Certificate, Digest, CSRF (Cross Site Request Forgery) etc.

RA out of the box has the support for BDD approach.

Follow the below steps to configure & test the SOAP web services.

How to read QR Code or Barcode from Images

Reading Barcodes / QR codes from images seems to be difficult & using the below open source libraries(ZXing - Zebra Crossing) provided by Google will make it simple for any application to include this functionality.

Curious on knowing how Android Apps scan the Barcodes or QR codes from the camera?

The android apps designed to scan 1D & 2D barcodes on a high level convert the data the camera into image bytes to the below library, which in-turn return the data embedded within the bar codes.

Follow the below steps to achieve the same.

Test REST Web Services using REST Assured API

REST Assured(RA) is a framework built on Java developed to test the REST services. It supports any HTTP method but has explicit support for GET, POST, PUT, DELETE, HEAD, OPTIONS, PATCH and includes specifying & validating like Headers, Cookies etc.

RA has inbuilt support for multiple authentication like BASIC, OAuth, OAuth2, Form, Certificate, Digest, CSRF (Cross Site Request Forgery) etc.

RA out of the box has the support for BDD approach.

Follow the below steps to configure & test the REST web services.

Text To Speech Using Voice RSS API

RSS Feeds are well known in the internet world. The new Voice RSS service brings the Speech Synthesis to a new level, where one can get the benefit of this feature with its Cloud Based Solution [SaaS] which requires no installation, no dependency on the technology, fast and accessible at all times.

Voice RSS exposes the Web Service / API to convert the given text into speech. 
Follow the below steps.

Convert Text to Audio using FreeTTS

Converting a text to audio may have multiple use cases in automation like creating the audio files for any data feed, voice driven tests etc.

FreeTTS[Free Text To Speech] is a library based on Java Speech API which is built on core technologies like Speech Synthesis and Speech Recognition.

Follow the below steps to configure & code to CONVERT TEXT TO AUDIO

Handle Windows Authentication Dialog in Automation - Selenium WebDriver

Windows Authentication dialogs are common when we are working in ODC environments.This would cause initial hickup for automation as the authentication pop-ups are out of DOM structure. This can handled in several ways like AutoIT, Sikuli, etc.

Below is one of the simplest way to handle.

Launch Browser with Extensions - Webdriver

Launching the selenium webdriver, by default opens the plain browser without any extensions.
But there is way, to launch the chrome browser along with the pre-installed extensions.

To load any chrome extension in webdriver, we need to package the extension to .crx file & refer the same file in the desired capabilities / chrome options to load when the browser is launched.

Follow the steps mentioned in the below link to create .crx file.
https://developer.chrome.com/extensions/packaging

Refer the *.crx file path in your code & launch the browser.

Launch Selenium Browser in Emulation Mode or Mobile Mode

Responsive Design Websites are the hot website design in recent days which fits to all device resolutions. Testing the responsiveness of the website on multiple resolutions is very important.

In the absence of real devices or if the application is in development mode, one can launch the selenium browser in mobile/emulation mode by setting the desired capabilities.

Below code snippet would help in launching the browser in emulation mode.
NOTE: This option is very good alternative for Emulators while testing web-app responsiveness.
