Advantages of QTP over Selenium

QTP	Selenium
Can test  both web and desktop applications	Can only test web applications
Comes with a  built-in object repository	Has no built-in object repository
Automates faster than Selenium Because it is a fully featured IDE.	Automates at a slower rate Because it does not have a native IDE and only third party IDE can be used for development
Data-driven testing is easier to perform Because  It has built-in global and local data tables .	Data-driven testing is more cumbersome since you have to Rely on the programming language's capabilities for setting values ​​for your test data
Can access controls within the browser (such as the Favorites bar, Address bar, Back and Forward buttons, etc.)	Can not access elements outside of the web application under test
Provides professional  customer support	No official user support is being offered.
Has native capability to  export test data  into external formats	Has no native capability to export runtime data onto external formats
Support Parameteriza- station is built	Parameteriza- station can be done through programming but is kettle to implement.
Test Reports are generated automatically	No native support to generate test / bug reports.

Advantages of Selenium over QTP

Selenium	QTP
Open source, free to use, and free of charge.	Commercial.
Highly extensible	Limited add-ons
Can run tests across different browsers	Can only run tests in Firefox , Internet Explorer and Chrome
Supports various operating systems	Can only be used in Windows
Supports mobile devices	Supports mobile device using 3rd party software
Can execute tests while the browser is minimized	Needs to have the application under test to be visible on the desktop
Can execute tests in parallel.	Can only execute in parallel but using Quality Center which is again a paid product.

Introduction of WebDriver

The WebDriver proves itself to be better than both Selenium IDE and Selenium RC in many aspects. It implements a more modern and stable approach in automating the browser's actions. WebDriver, unlike Selenium RC, does not rely on JavaScript for automation. It controls the browser by directly communicating to it.

The supported languages are the same as those in Selenium RC.

• Java
• C#
• PHP
• Python
• Perl
• Ruby

Introduction of Selenium Remote Control (Selenium RC)

Selenium RC was the flagship testing framework of the whole Selenium project for a long time. This is the first automated web testing tool that allowed users to use a programming language they prefer.As of version 2.25.0, RC can support the following programming languages:

• Java
• C#
• PHP
• Python
• Perl
• Ruby

Introduction of Selenium IDE

Selenium Integrated Development Environment (IDE) is the simplest framework in the Selenium suite and is the easiest one to learn. It is a Firefox plugin that you can install as easily as you can with other plugins. However, because of its simplicity, Selenium IDE should only be used as a prototyping tool. If you want to create more advanced test cases, you will need to use either Selenium RC or WebDriver.

How to Setup and Configure Selenium Webdriver With Eclipse and Java.

Step 1:

In the first step, download and install JDK (Java Development Kit) in your system.

For downloading Java, you need to visit the following link:

http://www.oracle.com/technetwork/java/javase/downloads/index.html

Step 2

In the second step, download and install Eclipse from the link below:

http://www.eclipse.org/downloads/

 

Step 3

Download the Selenium Java Client Driver from:

http://docs.seleniumhq.org/download/

Click on the download link for Java language, you will get a ZIP file named “selenium-2.43.0.zip”.

Then extract the contents of this ZIP file on any location say “D:\selenium-2.43.0\”.

The unzipped folder contains the ‘libs’ folder, 2 jar files and Change Log.

Step 4

Configure Eclipse to work with Webdriver:

Double click on ‘Eclipse.exe’ to launch eclipse

When asked to select for a workspace, just accept the default location. Or, you can change the location.

Create a new project through File -> New -> Java Project.

Name the project as “MyProject”.

Right-click on the newly created project and select New > Package, and name that package as “MyPackage”.

Create a new Java class under MyPackage by right-clicking on it and then selecting New > Class, and then name it as “MyClass”.

Your Eclipse IDE should look like the image below:

Step 5

Add Jar Files to the Library:

Right-click on MyProject and select “Build Path” and then “Configure Build Path”.

This will open the Libraries tab in Properties dialog. Then on click “Add External JARs...”

Navigate to D:\selenium-2.43.0\ (or any other location where you saved the extracted contents of “selenium-2.43.0.zip”).

Add all the JAR files inside and outside the “libs” folder.

These are the Jar files present outside the Libs folder:

These are the Jar files present inside the Libs folder:

Then your Properties dialog should look similar to the image below:

Finally, click on the OK button and we are done with importing Selenium libraries into our project. Now, we are ready to write our test script in Eclipse and run it in WebDriver.

Simple example of creating a webdriver script with explanation in the form of comments.

For this, we need to write the following code into Eclipse:

package MyPackage;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.firefox.FirefoxDriver;

public class MyClass {

    public static void main(String[] args) {

       //Create a new instance of Firefox Browser

       WebDriver driver = new FirefoxDriver();

       //Open the URL in firefox browser

       driver.get("https://www.google.co.in/");

       //Maximize the Browser window

       driver.manage().window().maximize();

       //Get the current page URL and store the value in variable 'str'

       String str = driver.getCurrentUrl();

       //Print the value of variable in the console

       System.out.println("The current URL is " + str);

   }

}

Now, click on the Run Menu of the Eclipse window to execute the script.

As an output, it will open the Firefox browser, maximize the browser window, get the current page URL and print the value in the console.
