Selenium – Testing Tool

Seleniumonlinetraining.info

What is Selenium?

• Selenium is a robust set of tools that supports rapid development of test automation for web-based applications.

• Works anywhere JavaScript is supported

• Hooks for many other languages - Java, Ruby, Python

• Can simulate a user navigating through pages and then assert for specific marks on the pages

• All you need to really know is HTML to start using it right away

Selenium

• You can use open source - Selenium tool

• Selenium IDE is a plug-in to Firefox to record and playback tests (like WinRunner, QTP).

• You can then export the recorded test in most language e.g. HTML, Java , .NET , Perl , Ruby etc.

• The exported test can be run in any browser and any platform using "selenium remote control".


Where to get it?

• You can use Selenium-Core and customize everything – deprecated.

• But it is easier to just get a Firefox plug-in “Selenium-IDE” that helps you “record” test Cases.

• You can record how an app is being used and then playback those recordings followed by asserts.

Selenium Components


Selenium-IDE• Integrated Development Environment for building Selenium test

cases. • Operates as a Firefox add-on and provides an interface for

developing and running individual test cases or entire test suites.

• Selenium-IDE has a recording feature, which will keep account of user actions as they are performed and store them as a reusable script to play back.

• It also has a context menu (right-click) integrated with the Firefox browser, which allows the user to pick from a list of assertions and verifications for the selected location.

• Offers full editing of test cases.• Although it is a Firefox only add-on, tests created in it can also

be run against other browsers by using Selenium-RC & specifying the name of the test suite on the command line.

Selenium-RC (Remote Control)

• Selenium-RC provides an API (Application Programming Interface) and library for each of its supported languages: HTML, Java, C#, Perl, PHP, Python, and Ruby.

• This ability to use Selenium-RC with a high-level programming language to develop test cases also allows the automated testing to be integrated with a project’s automated build environment.


Selenium-Grid

Selenium-Grid allows the Selenium-RC solution to scale for test suites or test suites to be run in multiple environments.

• With Selenium-Grid multiple instances of Selenium-RC are running on various operating system and browser configurations, each of these when launching register with a hub. When tests are sent to the hub they are then redirected to an available Selenium-RC, which will launch the browser and run the test.

• This allows for running tests in parallel, with the entire test suite theoretically taking only as long to run as the longest individual test.

Steps to start with Selenium!

1) Begin: write and run tests in Firefox.Selenium IDE is a Firefox add-on that records clicks, typing, and other actions to make a test, which you can play back in the browser.

2) Customize: your language, your browser.Selenium Remote Control (RC) runs your tests in multiple browsers and platforms. Tweak your tests in your preferred language.

3) Deploy: scale out, speed upSelenium Grid extends Selenium RC to distribute your tests across multiple servers, saving you time by running tests in parallel. seleniumonlinetraining.info

Selenium Commands – Selenese1) Actions are commands that generally manipulate the state of

the application. They do things like “click this link” and “select that option”.

• Can be called with “AndWait” suffix, e.g. “clickAndWait”.

2) Accessors examine the state of the application and store the results in variables, e.g. “storeTitle”.

• They are also used to automatically generate Assertions.

3) Assertions are like Accessors, but verify that the state of the application conforms to what is expected. Eg. “make sure the page title is X”, “verify that this checkbox is checked”.

• All Selenium Assertions can be used in 3 modes: “assert”, “verify”, and ” waitFor”. For example, you can “assertText”, “verifyText” and “waitForText”.

Creating a Test Suite

A Test Suite in Selenium is just an HTML file that contains a table of links to tests

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head>

<meta content="text/html; charset=UTF-8" http-equiv="content-type" /> <title>Test Suite</title>

</head><body>
