_ Automation testing – Selenium – 10x efficient

Why use automation testing?

Automation testing is an important topic nowadays because creating automated tests for any web application is a challenge for everyone, and it’s probably a challenge that you’ve experienced. Users are testing applications to keep pace with new features while balancing the need for integration and regression tests.

The lead times of test automation can be seriously decreased while improving the accuracy and consistency of them. Two of the biggest barriers to getting started are picking an automation tool and developing a framework for writing the tests.

Selenium WebDriver vs Selenium-RC.

Selenium WebDriver uses each browser as native support for automation and makes direct calls to the browser. How these direct calls are made, and the features they support, it all depends on the browser you are using. You can learn information on each browser driver in the course.

  • Selenium-RC: It uses Javascript to drive the web page, and it runs inside the Javascript sandbox.
  • Selenium WebDriver (has support for a few browsers): It uses native automation, which is less prone to errors and faster.

For those who are familiar with Selenium-RC, this differs from what you have used too. Selenium-RC works in the same way for each supported browser. When the browser is loading, it injects JavaScript functions into the browser and then used JavaScript to drive the AUT within the browser. But the WebDriver does not use this technique.

Setting Up a Selenium WebDriver Project.

Installing a Selenium means you are setting up a project in development so you can write a program using it. How you do this depends on your development environment and your programming language.

Java

The easiest way to install a Selenium 2.0 Java project is to use Maven. Maven will download the Java bindings and all the dependencies and will create a project for you by using a maven pom.xml file. Once you have done this, you can now import the maven project into your preferred IDE, Ellipse or IntelliJ IDEA.

Before starting, create a folder to add your Selenium project files. Then you need a pom.xml file to use Maven. You can create it with a text editor. We won’t give the details for using Maven. Your pom.xml file will look something like this. Create this file in the folder you created for your project.

Be sure you specify here the most current version. Now, copy CD into the project directory, and run Maven from a command line. This will download Selenium and all dependencies and will also add them to the project. Then import this project into your preferred developed environment.

C#

In Selenium 2.2.0, the C# bindings are distributed as a set of signed DLLs along with other DLLs. Before 2.2.0, all selenium DLL was unsigned. Here, if you are using Windows Vista or above, you have­­ to unblock the zip file from properties before unzipping it.

Unzip all the contents of the zip file and add a reference to every unzipped DLL to your project in Visual studio or any other to your choice.

Python

If you are using python for automation testing, then maybe you are also familiar with developing with python. To add Selenium to your python environment, run the following command from the command line. Pip installs selenium. Pip requires pip to be installed, and it also has the dependency on setup tools.

PHP

It provides these bindings by third-party, refer to their documentation on how to get started/install.

Javascript

If you use ode.js for developing your applications, the selenium project provides you with Javascript bindings on npm file. Install the Javascript bindings with npm by running the following command on any command-line: npm install selenium-WebDriver.

Software Automation Framework Support Engines.

You can take some general-purpose tools and apply them to any specific keyword-driven engine implementation. You can migrate from one automation testing tool to another, or even can use various automation tools simultaneously. E.g. you could use Selenium WebDriver and IBM Rational Functional tester at the same time.

The list of supported implementation:

Some (final) thoughts

Keep in mind
  • Selenium WebDriver is a powerful test tool to conduct Functional and regression testing. Selenium is open-source software that supports various programming languages, Browsers, and Operating Environment.

  • Selenium WebDriver can also used to conduct Batch Testing, Data-Driven Testing, Cross-Browser Testing, and Database Testing.
