Why consider Open Source Tools for Test Automation?

More than a decade ago, most of the organizations opted for commercial tools like QTP, Silk Test etc. to automate the applications. But with the rise of agile methodologies and with the ever-increasing importance of continuous development & continuous integration, and with the availability of matured open source tools having a terrific supporting eco-system, they have unarguably become a viable alternative now. Hence, we see most of the organizations migrating from commercial tools to open source. Here are few key points to ponder on both Open Source and Commercial Tools option:


Open Source

Commercial Tools

  • Free of cost
  • Easy availability
  • Support multiple technologies & operating systems
  • Require strong technical skills to use
  • Freedom of customizing the source code
  • High cost and licensing prices
  • 24 X 7 dedicated support
  • Technology specific
  • Easy to use


Innominds Test Automation COE has deep expertise in diverse Automation tools and Frameworks used for various Applications across Web, Mobile, APIs and Desktops.

As part of the continuos innovation, we developed homegrown Automation accelerator, Harmony ™ built up on open source technologies.

There are several reasons and factors for migrating to open source tools from commercial tools. Here are few compelling reasons.

Low Maintenance Cost

Most important factor is, it is budget friendly. We do not need to spend a fortune to use the open source software/tools. They are available absolutely free of cost. Also, we get frequent software/tool updates to support the environments and browsers.

OS & Language Compatibility

Most of the open source tools support multiple programming languages like C#, Java, Python etc., so there is no need to put an extra effort on training the resources on technologies. Also, these open source tools are OS agnostic and we can use them on most of the operating systems.


Most of the open source tools come with the source code. It gives us the ability to modify it as per our needs. The flexibility that comes with an ability to customize the tool to our specific work flow or for our organization’s business logic properties, makes open source undeniably a great option.

Code Reusability 

Most of the open source tools are language independent and can support most of the object oriented languages. The major advantage of the object oriented languages is code re-usability. We can maintain the common repository of the code and can re-use it anywhere.

Cloud Compatibility

Open source tools always give us a chance to integrate with cloud where we can perform our test executions on multiple environments and multiple browsers. Once we are done with the environmental setup on cloud, then we can execute all our automation scripts anywhere, any time.

Active Support 

We will get wide range of support from the developer community who actively engage in solving the issues and share the information on new features, updates etc. The vitality of an open source tool primarily depends on the constant work of volunteers using the code and either fixing issues or reporting them. With the help of developer communities and automation engineers, new issues are bound to get discovered, and can be quickly repaired most of the time before any serious damage can take place.

Ease of Execution & Reporting

Open source tools might sometimes offer exciting customization options to build up on the technical capabilities of the testers, especially in areas such as reusable frameworks, enhanced reporting capabilities etc. Most of the open source tools will support parallel execution of tests on different environments. This parallel execution saves lot of time when we are automating bigger applications.
