Which are the Most Popular Tools for Functional Automation Testing?

The need for “quality at speed” in software testing requires organizations to implement the right functional automation tools. Functional testing is a vital part of the software development life cycle and should be carried out with great tools for quality products at the end of the process. You need to understand that success in functional automation testing is more about avoiding mistakes and getting every testing right.

There are several reasons why you should choose automated testing over manual testing when testing the functionality of your software product. The results of automated testing are more reliable than those of the manual testing process. This is because tools are more accurate, unlike human beings prone to making errors during testing. In terms of coverage, you can achieve more test coverage with automated testing than with manual testing. The use of functional testing automation tools in automated testing makes it possible to carry out repetitive tasks more easily than when humans are entirely involved in carrying out these processes.

Below are the most popular tools for functional automation testing.

Unified Functional Testing (UFT)

UFT is one of the best and most popular commercial testing tools for functional automation. This tool provides great features for testing the API, graphic user interface and web services across different platforms. Unified Functional Testing has advanced image-based object recognition features, automated documentation and reusable test components that you can use for the functional testing of your application. It’s relatively costly due to the licensing, but the benefits of using it for functional automation testing are unmatched.

Tricentis Tosca

Tricentis Tosca is mainly used to simplify end-to-end functional testing by automating several tests across the layers of the enterprise software architecture. The layers in this testing include the mobile, API to web and packaged app user interfaces to the data warehouses. Tricentis Tosca is designed to embrace and carry out extensive application testing while continuously enabling continuous testing in the CI/CD process.
