Regression testing is a process of assuring the changes made to the test do not have unintended consequences on the behaviour of the test object. It is performed post the changes are made to the software code. Though there exists a great deal of discussion on what practices to follow for regression tests, there is literally no discussion on selecting the right tool for your selenium tests. This article discusses some of these tools.
Tools Used for Regression Testing
Choosing the right tool for regression tests can be a time-consuming process, but at the same time, identifying the right tool can offer a great support in terms of efficiency and time costs. Currently, there exist several tools that enable regression testing of user interfaces. These tools also offer equivalent functionality and hence can be used in other forms of testing processes as well. Some of these tools are given below:
1. Selenium IDE
The popular Selenium IDE is a set of corresponding software tools that are normally used to do automation testing of web applications. It was developed by ThoughtWorks since 2004 and provides a rich set of testing functionalities which are compatible with almost all widespread software platforms and web browsers. Selenium IDE provides a great experience as far as regression testing is concerned and is released under opensource license Apache 2 and hence, available free of cost. There is also an added advantage of community support provided by a large community of volunteers through user discussion groups.
Based on Selenium RC framework, Tellurium is yet another regression testing tool for web applications that are regularly updated since 2008. Tellurium is also freely available for commercial use and is based on Apache 2 license framework. It can be considered to be an upgrade to Selenium of sorts since it removes the lack of robustness in such tools.
3. WebAii Framework
WebAii is a framework for automated testing of web applications, originally developed by the company ArtOfTest later acquired by the company Telerik. The framework continues to be actively developed, supported completely free of charge, but it is not open-source. Since this is the platform closely associated with the operating system Microsoft Windows it supports creating tests in programming languages C# and Visual Basic .Net.
Xebium is a tool for creating automated integration, acceptance and regression tests and can be utilized as a testing framework for functional testing of the user interface of web applications. Xebium is a combination of three frameworks. These are Selenium IDE, Selenium WebDriver and FitNesse.
6. Telerik Test Studio
In addition to the freely available framework described before, the company ‘Telerik’ develops an application for testing and test automation called the Telerik Test Studio. Telerik is a commercial system primarily based on WebAii framework, hence offers support for the same web frameworks and browsers for regression testing. It also has support for automated testing of applications for mobile devices. Currently, there is an available solution for Apple iOS which is used by mobile phones (iPhone), tablets (iPad) and music players (iPod). This solution not only enables the testing of web applications but also testing of native mobile applications. Apart from regression testing, it can perform other alternative features such as:
- Support for testing desktop applications based on WPF
- Performance testing.
- Load tests – test a large number of concurrent accesses to the web application.
- Storing and managing test suites.
FitNesse is an open-source project implemented in Java and based on the FIT21 framework. It is designed to support the creation and maintenance of the acceptance test suite. It is created in order to enable software developers, testers and customers collaboratively develop tests for web applications. It, therefore, supports features that make it possible to easily create readable tests without any programming skills. Originally it was developed for the Java language, but currently also programming languages C++, Python, Ruby, Delphi and C# are supported.
Other Useful Tools
These tools can be used in process of creating, debugging and deploying automated tests. They offer a variety of features such as simple localization and selection of the elements present on the web page. Some of these are:
1. Firebug – Firebug is a plugin to the Mozilla Firefox web browser. It is a very popular tool used to develop and debug websites. It is the open-source project licensed under BSD license. The basic functions are:
- Review and modify HTML
- Review and edit CSS styles
- Network monitor
- Review DOM model of the site
- Interactive debugging in a GUI
2. FirePath – FirePath is a Firebug extension that adds the development tool designed to generate, edit and review of XPath expressions, CSS 3 and JQuery selectors.
3. Hudson – Test automation requires the introduction of the system for continuous integration (CI). System for CI should support source code revision systems and it also should contain some kind of the task scheduler for the automatic task execution. Among tools like that belong also Hudson. It supports the project version control, application build tools (e.g. Ant), scheduling, different execution mechanisms and straightforward GUI that enables users to monitor executed tasks and review tasks reports. The tool provides many different plugins that can be used to enable integration with other tools as for instance the plugin for the TestNG or Selenium framework.
