Open Source Functional Testing Tools – Part 1

A Look at Some Open Source Functional Testing Tools-blog

There are numerous risks involved in the release of a software product without rigorous testing as it has a significant impact on the expectations and demands of the end users. Functional testing is a key element for enhancing the quality of the software product as it verifies and checks whether or not the software application performs and functions according to the design specifications. It is important to test the application’s usability as testing at the user interface level can reveal a number of defects that might not be apparent while conducting a source code review. Hence, irrespective of the quality of the underlying code, if the user interface doesn’t work, the result is a frustrating experience for the user. Thus, performing functional testing of the software is not only basic but also important and crucial.

Functional Testing can be performed using many open source functional testing tools that help ensure speed of delivery, improve the release quality, and reduce testing costs. Some of the open source functional testing tools have been detailed in this article.

 Cucumber: Cucumber is designed for Behavior Driven Development. With Cucumber, you can describe the behavior in plain text, write a step definition in Ruby, run and watch it fail. Failing proper output, write code to make the step pass, run again, and see that the step passes. It supports more than twenty spoken languages, and programmers write code of Ruby or Java to wire the plain text tests to the system. It helps to encourage conversation between all stakeholders involved to depict examples to make things clearer. It further reduces ambiguity and helps others to agree on what they are building. Cucumber supports Ruby, Java, .Net, Flex, etc. languages.

JBehave: JBehave is also designed for Behavior Driven Development (BDD) and has a Java-based framework. It is an extension from Test Driven Development (TDD) to BDD as it enables a significant improvement in the communication amongst the teams and business stakeholders. It primarily focuses on providing a clear understanding of the desired software behavior through consolidated discussions with the stakeholders. It extends TDD by writing test cases in a natural language that helps the users, stakeholders, and the project management team to easily understand it though without any technical knowledge or support.

JFunc: JFunc is an extension of the JUnit Testing Framework and used with functional tests. It has been exclusively designed to address issues of functional testing that is also known as system/integration/scenario testing. It helps to analyze not only the differences in code but also the differences in methodology.

Maveryx: Maveryx is an open source test automation framework used for functional testing, regression testing, GUI testing, and data driven testing of all Java-based applications. Though it is simple, but is a powerful, innovative, lightweight, and a fully featured framework that eliminates the GUI Map dependency. This tool allows users to run the same scripts without modification against Java desktop applications as well as on any Android app on real mobile devices or on simulators.

Watir: It stands for Web Application Testing in Ruby and is a functional testing tool for web applications. It allows automating web browsers to test web applications and is a simple, flexible tool. It is easy to write and maintain test cases. By using it, you can click links, fill in forms, press buttons, check the results, etc. The Watir-Webdriver supports Chrome, Firefox, Internet Explorer, and Opera browsers. It allows connecting to databases, read data files and spreadsheets, export XML, and structure code as reusable libraries.

The above detailed tools are a few of the popular functional testing tools used by software testers that allow them to perform testing in an effective manner to identify and notify bugs. Another approach is to opt for some functional testing service providers who help software vendors and enterprises reduce costs and increase their ROI. Cigniti’s functional testing services begin with an assessment of the application/product requirements which is followed by a clearly defined implementation plan aligning functional testing objectives with the overall business goals.

If you have been using functional test automation tools like UFT and LeanFT and are looking out for the latest migration accelerators, you can go with Cigniti’s QuickLean solution. It is the world’s first migration accelerator that eases the migration of your UFT scripts to LeanFT.

However, if you expect a comprehensive functional testing service to be conducted in a systematic way, check out our website to know more.

    As to complete your list, we could mention Squash TM (, one of the best open source and free management test tools on the market with several key features, among which: intuitive and efficient ergonomics, innovative features (inter-project and multi-projects, wizards), easy deployment (full web technology), designed for collaborative work (shared work/performance/security), real-time customized charts and dashboards.

    The platform is often improved with new functionalities.

    The next version should introduce a major change for test automation: a Jenkins plugin that will allow to trigger builds and get the results directly on Squash TM! This plugin will be available on Jenkins marketplace this summer.
