Selenium Overview,Selenium IDE Introduction⌘

A process of writing a computer program to do testing that would otherwise need to be done manually
Use of software to control the execution of tests

Two types of test automation:

Reliable: Tests perform precisely the same operations each time they are run, thereby eliminating human error.
Repeatable: You can test how the software reacts under repeated execution of the same operations.
Reusable: You can reuse tests on different versions of an application, even if the user interface changes.
Speed: Run tests significantly faster than human users.
Cost Reduction: As the number of resources for regression test are reduced.
Better Quality Software: Rapid feedback to developers during the development process as a result of frequent regression testing.

Proficiency is required to write the automation test script.
Debugging the test script is major issue. If any error is present in the test script, sometimes it may lead to dadly consequences.
Test maintenance is costly in case of playback methods. Even though a minor changes occurs in the GUI, the test script has to be rewritten.
Maintenance of test data files is difficult, if the test script tests more screens or web-pages.
Short iteration or very tight deadline, there is not enough time to build test automation.

A set of tools that supports rapid development of test automation for web-based applications.

Can be recorded and written as HTML
Support for a number of programming languages: Java, C#, Perl, PHP, Python, Ruby
Cross browsers support: IE, Firefox, Opera, Safari and Google Chrome
Cross platform support: Windows, Linux, and Macintosh.

Invented in 2004 by Jason R. Huggins and team.
Originally named JavaScript Functional Tester [JSFT]
100% Javascript and HTML
Designed to make test writing easy
Open source browser based integration test framework built originally by ThoughtWorks
Selenium is open source software, released under the Apache 2.0 license and can be downloaded and used without charge.

Selenium is a chemical element with the atomic number 34, represented by the chemical symbol Se.

Selenium is used for treating Mercury poisoning

Products: QTP, WinRunner, LoadRunner and TestDirector

Selenium IDE (SIDE) is a complete Integrated Development Environment (IDE) for building Selenium test case.
Firefox add-on that makes it easy to record, edit, and debug tests.
Provides an easy-to-use interface for developing and running individual test cases or entire test suites.
Can be used to generate code to run the tests with Selenium Remote Control (RC).

Record, playback, edit
Intelligent component identification will use object IDs, names, or XPath as needed
Auto complete for all common Selenium commands
Walk through test cases and test suites.
Debug and set breakpoints
Save tests as HTML, or export as other supported programming languages
Support for Selenium user extensions
