Best Automation Testing Tools in 2020 (Top 10+ reviews)

Best Automation Testing Tools

In this post, we will see the Best Automation Testing Tools for 2020.

Software development practices change over time, so do the tools and technologies. Such changes aim to improve productivity, quality, customer satisfaction, to tackle ever-shorter delivery time, and to deliver successful products and services. Software testing obviously plays an important role in achieving these objectives.

The recently released World Quality Report 2017–2018 by Capgemini, Sogeti, and Marco Focus points out several interesting trends in software quality and testing. Two of three key trends are increasing test automation and widespread adoption of agile and DevOps methodologies. As the report shows, organizations need intelligent automation and smart analytics to speed up decision making and validation and to better address the challenges of testing smarter devices and products that are highly integrated and continuously changing. The report also suggests the need for smart test platforms that are self-aware and self-adaptive to support the complete application lifecycle.

In the test automation landscape, automation tools certainly take a center stage. This post summarizes the top test automation tools and frameworks that have the potential to help organizations to best position themselves to keep pace with the trends in software testing. The list includes both open-source and commercial test automation solutions.

Selenium is possibly the most popular open-source test automation framework for Web applications. Being originated in the 2000s and evolved over a decade, Selenium has been an automation framework of choice for Web automation testers, especially for those who possess advanced programming and scripting skills. Selenium has become a core framework for other open-source test automation tools such as Katalon Studio, Watir, Protractor, and Robot Framework.

Selenium supports multiple system environments (Windows, Mac, Linux) and browsers (Chrome, Firefox, IE, and Headless browsers). Its scripts can be written in various programming languages such as Java, Groovy, Python, C#, PHP, Ruby, and Perl.

While testers have flexibility with Selenium and they can write complex and advanced test scripts to meet various levels of complexity, it requires advanced programming skills and effort to build automation frameworks and libraries for specific testing needs.
