Selenium Overview

Test Automation for Web Applications

Many, perhaps most, software applications today are written as web-based applications to be run in an Internet browser. The effectiveness of testing these applications varies widely among companies and organizations. In an era of highly interactive and responsive software processes where many organizations are using some form of Agile methodology, test automation is frequently becoming a requirement for software projects. Test automation is often the answer. Test automation means using a software tool to run repeatable tests against the application to be tested. For regression testing this provides that responsiveness.

There are many advantages to test automation. Most are related to the repeatability of the tests and the speed at which the tests can be executed. There are a number of commercial and open source tools available for assisting with the development of test automation. Selenium is possibly the most widely used open source solution. This user’s guide will assist both new and experienced Selenium users in learning effective techniques in building test automation for web applications.

Test automation has specific advantages for improving the long-term efficiency of a software team’s testing processes. Test automation supports:

• Frequent regression testing

• Rapid feedback to developers

• Virtually unlimited iterations of test case execution

• Support for Agile and extreme development methodologies

• Disciplined documentation of test cases

• Customized defect reporting

• Finding defects missed by manual testing

Introducing Selenium

Selenium is a set of different software tools each with a different approach to supporting test automation. Most Selenium QA Engineers focus on the one or two tools that most meet the needs of their project, however learning all the tools will give you many different options for approaching different test automation problems. The entire suite of tools results in a rich set of testing functions specifically geared to the needs of testing of web applications of all types. These operations are highly flexible, allowing many options for locating UI elements and comparing expected test results against actual application behavior. One of Selenium’s key features is the support for executing one’s tests on multiple browser platforms.

Selenium’s Tool Suite

Selenium is composed of multiple software tools. Each has a specific role.

Selenium 2 (aka. Selenium Webdriver)

Selenium 2 is the future direction of the project and the newest addition to the Selenium toolkit. This brand new automation tool provides all sorts of awesome features, including a more cohesive and objects oriented API as well as an answer to the limitations of the old implementation.

As you can read in Brief History of The Selenium Project, both the Selenium andWebDriver developers agreed that both tools have advantages and that merging the two projects would make a much more robust automation tool.

Selenium 2.0 is the product of that effort. It supports the WebDriver API and underlying technology, along with the Selenium 1 technology underneath the WebDriver API for maximum flexibility in porting your tests. In addition, Selenium 2 still runs Selenium 1’s Selenium RC interface for backwards compatibility.

Selenium 1 (aka. Selenium RC or Remote Control)

As you can read in Brief History of The Selenium Project, Selenium RC was the main Selenium project for a long time, before the WebDriver/Selenium merge brought up Selenium 2, the newest and more powerful tool.

Selenium 1 is still actively supported (mostly in maintenance mode) and provides some features that may not be available in Selenium 2 for a while, including support for several languages (Java, Javascript, Ruby, PHP, Python, Perl and C#) and support for almost every browser out there.
