Most Popular Automated Testing Frameworks: Definitive Overview

It provides a better execution speed and coverage. Automation testing saves time and is free of human assistance. It considerably minimizes errors which is a common issue when the testing is done manually and has proved to be the best testing framework for complex software. Here are the most popular automated testing frameworks in the market.


Functionize automated software testing offers automated software testing through an intelligent test agent. The agent uses various artificial intelligence-based techniques to come up with accurate results.

The main aim of Functionize is to simplify automated software testing and make it accessible to anyone, irrespective of their skill levels.

Functionize system works on two core technologies – Natural Language Processing (NLP) which enables users to write test plans in simple and plain English, in both structured and unstructured texts.

From there, ML engine takes over, where AI creates a functional model of the UI. During the modeling phase, the test plans communicate with the ML tool on the details of the site being tested.

In the last stage, this multi-dimensional data is converted into fully-functional, self-healing tests that produce exceptional results.


Katalon is used to run automation testing for iOS, Android, Web interfaces, and APIs. During testing, the tool generates analyzed reports and test records. The cross-browser tool was released in 2015 and is a free license tool.

It can be deployed on Linux, macOS, or Windows. It is a powerful multipurpose tool that is easy to use. It can create and reuse its UI test scripts and does not require coding to perform this. It’s programmed to work on the Selenium and Appium automation frameworks to offer dual scripting interfaces.

This makes it possible for users without coding knowledge to use the tool without help from experts. Above all, Katalon seamlessly performs remote testing, local testing and can support both parallel and sequential executions.


Appium is used to test apps for mobile phones. The open-source testing tool uses JSON wire protocol to allow users to perform UI automation testing for hybrid mobile apps, native, and web-based apps on iOS and android operating systems.

The automation testing software can be integrated on several other frameworks to perform testing across multiple platforms using reusable test scripts.
