Open Source Testing Tools

In almost every software industry, Quality Analysis plays an integral role in the better delivery of the product. And to enhance the process of Quality Analysis, there are numerous tools available in the market which ease the work and effort involved. So to get a better understanding of these tools , it is very important to understand the features and the strengths and weaknesses of the tool.In this blog, we will be discussing the details of a few tools which are doing well in the market.

1 – Selenium : Selenium is an open source tool in which functional testing of both web and desktop application can be performed.


    • Pros:

      • Selenium has no additional costs. It is available on the web for free but is a community-based software.

      • There is no language barrier in Selenium as the developers/testers can use the language they are comfortable with such as C#, Java, JavaScript, PHP, Python and others.Which makes the tool platform independent.

    • Cons:

      • Selenium is not a complete, comprehensive solution to fully automating the testing of web applications as it needs third-party frameworks, language bindings and so on to be fully functional.

      • It demands high technical knowledge from the testers.


2 – Sahi : One of the best testing tools providing all the support required for automation testing.


    • Pros :

      • Sahi can achieve most of the automation with available functions and variables. It has all the inbuilt APIs required for complex tasks.Sahi also has a multi-browser support.

      • Sahi does not require additional tools to run and execute the tests.All the tests run from the inbuilt Sahi Controller.

    • Cons :

      • Compared to Selenium it is difficult to start as it involves a complex installation process.Sahi also a very confusing interface for its users.

      • SAHI does not provide the same visibility that Selenium does and it is less popular and has the smallest and least developed community.

3- Watir : Watir is an open source tool used to automate testing of web applications. Watir is simple and flexible tool with which it is easy to write and maintain test cases.


    • Pros :

      • External server is not required. Run the “ruby test.rb” and it works.

      • GREAT API! Easy to learn and once familiar with, one can write the code without need of much documentation.

    • Cons:

      • Implementation in each browser is different and the driver for each is different. There are scenarios where different result occurs in different browsers.

      • It is not widely used as compared to selenium.

4 – QTP : HP QuickTest Professional (QTP) is a tool that helps testers to perform automated regression testing to identify if any errors exist.


    • Pros :

      • It is easily understood even by a person with less technical knowledge.

      • QTP can be integrated with tools like Quality Center, Test Director and also with functional tools like Winrunner.

    • Cons :

      • High in Cost – License and maintenance.

      • Execution speed is less as compared to Selenium.

5- Canoo WebTest : Canoo Web Test is an automation tools that makes functional testing simple and fast with detailed reporting.



    • Pros :

      • It goes well when there are needs of customization. One can have their own steps without technology mix, exactly like Web Test’s have their own steps in Java or in Groovy and access the whole API of HtmlUnit, commons-HTTP client, … to enhance WebTest for your special requirements.

      • As the script used here is Ant scripts, it can be directly integrated with tools like Cruise control.

    • Cons :

      • “Real” browsers accept really badly formed HTML code what WebTest can only do to some extend.

      • WebTest simulates Firefox’ or Internet Explorer’s way to execute JavaScript. This behaviour is simulated, which means that it doesn’t work as good as in “real” browser.
