Best Open Source Automation Testing Tools in 2020

“As ironic as it seems, the challenge of a tester is to test as little as possible. Test less, but test smarter.”Federico Toledo

The most critical part of a software development process is Testing. This allows developers to validate software functionality, measure performance, and identify flaws to remediate. Being this huge domain, software testing can be categorized into manual testing and automation testing. On the basis of project requirements, budget, timeline, expertise, and suitability, the goal of software testing is to maintain the quality output to deliver a successful project. 

Manual testing is like the classic way to execute test cases manually by the human eye without any tool or scripts support. It is very much important and needed as humans can incorporate intelligence and necessary inputs based on different scenarios while thinking out of the box.

With the increasing complexity in software projects and accelerated project development cycles, there was a need to leverage automated testing with manual testing to meet the testing objectives within acceptable timeframes. This was done to ensure better consistency, efficiency, ongoing maintenance, and advanced enhancements of the system.

Why is automation testing important?

Automation software testing is both a tool and a process. Automation testing tools provide the mechanisms and functions needed to execute tests on a software product. The tests can vary, ranging from simple scripts to detailed data sets and complex behavioural simulations. All the tests aim to validate that the software provides intended functionality and behaves as expected within acceptable parameters.

Automation testing is well-suited for large projects; projects that require testing the same areas over and over. It helps in the comparison of actual outcomes with predicted outcomes. Thus, automation testing has become a vital part of quality assurance.

Top Open Source Automation Testing Tools in 2020

All open-source tools that serve a definite purpose of software testing are known as open-source testing tools. Given below is a list of useful open source testing tools that are definitely going to help you in selecting the right tool.

Selenium

Selenium is the household name amongst testers as it is considered the industry standard for user interface automation testing of Web applications. According to a survey, 84% of developers are using or have used Selenium. It automates browsers, allowing users to breeze through numerous browser-specific testing purposes.

Selenium aides to create effective test scripts for regression testing, exploratory testing, and quick bug reproduction. Selenium offers flexibility that not many other test automation tools and frameworks provide. Users can write test scripts in many different languages that run on multiple system environments and browsers. It is noteworthy to know that most major browser vendors are taking steps to make Selenium an integral part of their browsers.

Appium

Appium is a test automation framework primarily envisioned for mobile applications. Built on client/server architecture, Appium automates the applications that are created for iOS and Android. It’s built with the idea that one should not be recompiling your app or modifying it in any way in order to test it or be locked into a specific language or framework to run your tests.

Appium is easy to install, easy to use, supports cross-platform applications, and allows them to test against multiple platforms using the same API. Supports native, hybrid, and mobile web applications and desktop apps.

Mostly, Appium used along Selenium is a perfect combination to test mobile applications. Both Appium and Selenium use the same protocol (The WebDriver API) and use the same client libraries to control target platforms. To test a mobile and desktop browser compatible application, Appium and Selenium can be used together to reduce the testing time for the app.

Katalon Studio

Katalon Studio an all-in-one solution that supports web, API, mobile, and desktop app test automation. It enables cross-functional operations for product development teams on a large scale. As a codeless solution, Katalon Studio is user-friendly, robust to expand, and also contains the necessary components for advanced needs with built-in keywords and project templates – making it perfect for cross-browser testing.

In addition, it provides a host of seamless integrations with SDLC management, CI/CD pipeline, team collaborate applications, etc. Users can leverage Katalon Store – a plugin and extension marketplace, to add more features and optimize their test automation strategies.

Cucumber

A cucumber is an open-source tool based upon the Behavior Driven Development (BDD) concept using which Cucumber allows you to do automated acceptance testing by executing the examples that optimally describe the behaviour of the application.

Drafting test scripts is a joint effort of testers, developers, and customers. Cucumber supports only the web environment. The test code is written in simple English called Gherkin. It has cross-platform OS support and compatibility with programming languages like Ruby, Java, Scala, Groovy, etc.

The best part to prefer Cucumber is that is focused on user experience and allows us to maintain a single live document for both specification and test documentation.

SoapUI

SoapUI is a headless functional testing tool specifically designed for API testing. SoapUI supports both REST and SOAP services. 

Having comprehensive features, SoapUI is loaded with advanced capabilities like asynchronous testing, easily reusable scripts, Powerful data-driven testing with data from files and databases, Generating tests easily using drag and drop, point-and-click, and more.

Watir

Watir (pronounced as water) is an acronym for Web Application Testing In Ruby. It is a powerful tool for it is famous for being an extremely lightweight, technology-independent testing tool for web automation. Watir supports cross-browser, data-driven testing, and supports your web app irrespective of the language developed in.

The test scripts are easy to read and maintain. Also, it integrates seamlessly with BBD tools like Cucumber, Test/Unit, etc. Extendable through a set of different APIs manual browsing is combinable with commands in Ruby. As long as it’s written in Ruby, it gives you the power to connect to databases, read data files and spreadsheets, export XML, and structure your code as reusable libraries

Robotium

Robotium is a popular automation testing framework, mainly intended for Android UI testing – supports both native and hybrid applications. It supports grey box UI testing, system testing, functional testing, and user acceptance testing. It also makes writing automated black-box test cases easy.

Robotium integrates seamlessly with Gradle, Ant, and Maven which helps to run test cases as continuous integration.
