Selenium

Selenium is a Open source Software Functional Testing Tool

Introduction

The Selenium-IDE (Integrated Development Environment) is the tool you use to develop your Selenium test cases(Test Script in HTML and command ). It’s an user-friendly Firefox plug-in and is usually the nearly everyone professional 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.

Installing the IDE

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

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

Out of the many open source test automation tools available today, there is one tool that become very popular in recent times Selenium.

Selenium is a web application test automation tool which provides many features and a wide range of support which makes it an instant choice for automating most of the web applications.

Selenium provides the automation engineer the choice of running the automation scripts in a wide range of browsers and with the language support it has, on wide range of operating systems too.

But there are certain things the automation engineer needs to be aware of before he jumps into understanding selenium. The automation engineer needs to have a basic knowledge of the following things:

1.  HTML 
2. XML
3. Xpath  
4. Document Object Model(DOM)
5.  JavaScript (only a basic knowledge on how events are triggered etc.)
6.  Any one of the following language to build a full-fledged test suite – Perl, Python, Ruby, Java, C#, PHP. 
7. Basic object oriented programming concepts. Once we are sure that we have the basics of the above mentioned seven points let us move on into what selenium is all about and various types of selenium.

Working with Selenium IDE:

 

Tool Bar Option

The toolbar contains buttons for controlling the execution of your test cases, including a step feature for debugging your test cases. The right-most button, the one with the red-dot, is the record button.

 

 

Speed Control: controls how fast your test case runs

 

Run All: Runs the entire test suite when a test suite with multiple test cases is loaded.

             

Run: Runs the currently selected test. When only a single test is loaded this button and the Run All button have the same effect.

           

Pause/Resume: Allows stopping and re-starting of a running test case.

.

Step: Allows you to “step” through a test case by running it one command at a time. Use for debugging test cases.

 

Apply Rollup Rules: This advanced feature allows repetitive sequences of Selenium commands to be grouped into a single action. Detailed documentation on rollup rules can be found in the UI-Element Documentation on the Help menu 

Record: Records the user’s browser actions.

Test Case Pane

Your script is displayed in the test case pane. It has two tabs, one for displaying the command and their parameters in a readable “table” format
