What is Selenium?

• Selenium is a web application testing framework that allows you to write tests in many programming languages like Java, C#, Groovy, Perl, PHP, Python and Ruby.

• Selenium deploys on Windows, Linux, and MAC OS.

• It is an open-source project, released under the Apache 2.0 license, so you can download and use it without charge.

Components of Selenium


Terminologies In Selenium

• Selenium Core (aka Core) is a set of JavaScript scripts that control the browser, imitating user activity. These scripts are injected into the web page and executed according to a list of actions written in a special HTML-table-based command language (aka Selense), thus simulating user activity.



• Selenium RC (aka Selenium Remote Control or Selenium 1) receives Selenium Core commands via HTTP and executes them on a remote machine, proxying the web browser in order to avoid the “same host origin” restriction. This also allows writing the tests in other languages like C#, Python, Perl, PHP, Java and Ruby (via language bindings for Selenium Core).



• Selenium-WebDriver (aka WebDriver or Selenium 2) is a successor of Selenium RC. It does the same job, but in a different way: instead of injecting a JavaScript code into the browser to simulate user actions, it uses the browser’s native support for automation (different for each browser). Also, instead of a dictionary-based API (used in Selenium RC), it offers the more convenient object-oriented API.

• Selenium Server allows using Selenium-WebDriver on a remote machine.

• Selenium IDE is a Firefox add-on that records user activity and creates a test case based on it. It can also play the tests back and save them as a program in different languages.

• Selenium-Grid allows you run the tests on different machines against different browsers in parallel; in other words it enables distributed test execution.

• Selenese is a special “language” represented by a set of Selenium commands that run your tests. A sequence of these commands is called a test script.


Selenium IDE

• Selenium IDE is software testing tool for web applications. It provides record and playback facility to regression test any web application. To use selenium IDE, It is not compulsory to have any programming language knowledge.

• Selenium IDE is open source web application testing tool. Selenium IDE provides facility to export recorded script in many languages like HTML, Java, Ruby, RSpec, Python, C#, JUnit and TestNG. You can use these exported script in Selenium RC or webdriver.



Pros and Cons of using Selenium

WebDriver for Website Scraping

Advantages

• WebDriver can simulate a real user working with a browser.

• WebDriver can scrape a web site using a specific browser.

• WebDriver can scrape complicated web pages with dynamic content.

• WebDriver is able to take screenshots of the webpage


Pros and Cons of using Selenium

WebDriver for Website Scraping

Disadvantages

• The program becomes quite large.

• A browser application needs to be started.

• The scraping process is slower.

• The browser generates a bigger network traffic.

• The scraping can be detected by such simple means as Google Analytics.
