*Better quality control
*Greater precision
*Increased Productivity
*Improved design through simulation (CAD/CAM) 

disadvantages
*price

what is difference between selenium and qtp
QTP
QTP can be used for testing client server applications
QTP is limited to Internet Explorer on Windows.
QTP uses scripting language implemented on top of VB Script


Selenium
Only web applications can be tested using Selenium testing suite
Selenium supports following web browsers: Internet Explorer, Firefox, Safari, Opera or Konqueror on Windows, Mac OS X and Linux
Selenium test suite has the flexibility to use many languages like Java, .Net, Perl, PHP, Python, and Ruby.

Selenium IDE:

The Selenium-IDE (Integrated Development Environment) is the tool you use to develop your Selenium test cases. It’s an easy-to-use Firefox plug-in and is generally the most efficient way to develop test cases. It also contains a context menu that allows you to first select a UI element from the browser’s currently displayed page and then select from a list of Selenium commands with parameters pre-defined according to the context of the selected UI element. This is not only a time-saver, but also an excellent way of learning Selenium script syntax.

This chapter is all about the Selenium IDE and how to use it effectively.

Installing the IDE

Using Firefox, first, download the IDE from the SeleniumHQ downloads page

Firefox will protect you from installing addons from unfamiliar locations, so you will need to click ‘Allow’ to proceed with the installation, as shown in the following screenshot.

What is Selenium?

Selenium automates browsers. That's it. What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should!) also be automated as well.

Selenium has the support of some of the largest browser vendors who have taken (or are taking) steps to make Selenium a native part of their browser. It is also the core technology in countless other browser automation tools, APIs and frameworks.

Which part of Selenium is appropriate for me?

If you want to create quick bug reproduction scripts create scripts to aid in automation-aided exploratory testing Then you want to use Selenium IDE; a Firefox add-on that will do simple record-and-playback of interactions with the browser

If you want to create robust, browser-based regression automation scale and distribute scripts across many environments Then you want to use Selenium WebDriver; a collection of language specific bindings to drive a browser -- the way it is meant to be driven. Selenium WebDriver is the successor of Selenium Remote Control which has been officially deprecated. The Selenium Server (used by both WebDriver and Remote Control) now also includes built-in grid capabilities.

Selenium RC:

Selenium Remote Control (RC) is a test tool that allows you to write automated web application UI tests in any programming language against any HTTP website using any mainstream JavaScript-enabled browser.

Selenium RC comes in two parts. 

1. A server which automatically launches and kills browsers, and acts as a HTTP proxy for web requests from them.
2. Client libraries for your favorite computer language.

Here is a simplified architectural representation....

Selenium Remote Control is great for testing complex AJAX-based web user interfaces under a Continuous Integration system. It is also an ideal solution for users of Selenium IDE who want to write tests in a more expressive programming language than the Selenese HTML table format.

How to download and install Selenium IDE?

Downloads

Below is where you can find the latest releases of all the Selenium components. You can also find a list previous releases, latest releases, source code, and additional information for Maven users (Maven is a popular Java build tool).

Selenium IDE

Selenium IDE is a Firefox plugin that does record-and-playback of interactions with the browser. Use this to either create simple scripts, assist in exploratory testing. It can also export Remote Control or WebDriver scripts, though they tend to be somewhat brittle and should be overhauled into some sort of Page Object-y structure for any kind of resiliency.

Download version 1.8.1 released on 01/June/2012 or view the Release Notes

how to use selenium ide toolbar elements

If you are new for using selenium IDE, then first of all you have to understand how to operate Selenium IDE.

Here i have described how to use selenium IDE different elements and its functions.

Speed Controller :

In Selenium IDE, Speed controller is used to control the speed of how fast your test case runs. Set it on fast if you want to run fast test case and set it to slow if you want to run your test case slow.

Run All Button :

In Selenium IDE, Run All button is used to run the entire test suite. Suppose you have created 5 test cases for you application and stored all them in one test suite and if you like to run all they 5 then open your test suite and press this button. it will run all the 5 test cases one by one. 

Run Button : 

 

 In Selenium IDE, Run All button is used to run the selected any one test case.

Pause/Resume Button :

 

  In Selenium IDE, pause button is used to pause the running test case and resume button is used to resume or restart paused test case.

Step Button :

 In Selenium IDE, Step button is used to run test commands manually one by one. Suppose you have paused your test case and now you like to run remaining commands one by one then you can use step button. Basically step button is used debug the script in selenium IDE.

Click to Record/ Stop Recording Button :

In Selenium IDE, Record button is used to record the users browser navigation and creating test script for reusing it and stop record button is used to stop recording.

Command Table :

Command table shows the recorded commands. you can also modify commands or insert any command in between. there are three elements in each command.

1.                  Command : Command column describes name of command.

2.                   Target : Target column describes Target element id or name or Xpath

3.                  Value : Value column describes Value of an element 

Selenium IDE - free web application testing tool

Selenium IDE is software testing tool for web applications. It provides record and playback facility to regression test any web application. To useselenium 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, Ruby, RSpec, Python, C#, JUnit and TestNG. You can use these exported script in Selenium RC. To using selenium IDE you have to download it from link given here. Click here to Free download Selenium IDE.You can find latest released version for downloading.But one thing i would like to clarify here is that selenium IDE supports only Mozilla Firefox web browser. So don't try to download it in any other web browser. See my next post to learn how to download and install Selenium IDE in step by step process.
