List of the Top 5 Functional Testing Tools for Tosca in 2025

SoapUI testing tools, offered in both open source and commercial versions, make it easier to create, manage, and execute thorough tests for a variety of services including REST, SOAP, GraphQL APIs, JMS, JDBC, and more, thereby accelerating software delivery. For developers and testers looking to boost their skills in delivering REST and SOAP APIs, SoapUI Open Source is the most accessible and intuitive option for starting API testing. The advanced tools are crafted to optimize the validation of REST, SOAP, GraphQL, microservices, and other backend services, allowing teams to effortlessly incorporate API testing into their continuous delivery workflows. APIs, or Application Programming Interfaces, are essential for facilitating the connection and exchange of data and logic across different systems and applications, forming the backbone of modern software development. By implementing effective testing strategies for these APIs, organizations can significantly improve the efficiency of their overall testing process, leading to faster software delivery and enhanced quality outcomes. As teams adapt to the fast-changing technology environment, maintaining a competitive edge relies on the robustness of their testing frameworks. Ultimately, the emphasis on thorough API testing not only ensures product reliability but also fosters greater innovation and responsiveness in development practices.

OpenText Functional Testing, formerly known as UFT One, is an advanced, AI-powered automated testing platform designed for enterprise-grade applications spanning desktop, web, mobile, mainframe, composite, and packaged software. It enables developers and testers to centralize and automate functional and regression testing across all layers, including both front-end UI and back-end API components, thus increasing overall test coverage. The tool uses sophisticated AI-based machine learning and optical character recognition (OCR) to deliver enhanced object recognition, natural language scripting, and simplified test maintenance, reducing manual effort. It supports scripting once and replaying tests across over a dozen browser versions including Chrome, Firefox, Safari, Edge, Internet Explorer, and Chromium Edge, ensuring consistent cross-browser validation. Parallel and distributed testing capabilities allow running multiple tests concurrently, accelerating test execution and integration with continuous integration/continuous delivery (CI/CD) pipelines. The platform encourages collaboration via reusable actions, promoting consistency and efficiency among team members. Fully integrated within a DevOps toolchain, it eliminates traditional testing bottlenecks to accelerate software delivery without sacrificing quality. OpenText Functional Testing supports more than 200 GUI and API technologies, making it suitable for a wide range of application types and environments. Organizations benefit from AI-powered insights and automation that reduce testing time and enhance software reliability. Supported by professional services and premium support, the platform is a powerful asset for enterprises committed to high-quality, fast software releases.

Selenium allows for the automation of web browsers, giving users a vast array of options to explore. Although its main purpose is to test web applications, its application goes far beyond that. It can also efficiently automate repetitive administrative tasks conducted online, which leads to a significant enhancement in productivity and a reduction in monotony. For developers aiming to create thorough regression automation suites and distribute their scripts across different environments, Selenium WebDriver is the optimal solution, providing language-specific bindings for effective browser control. On the other hand, if you seek to quickly generate scripts for reproducing bugs or wish to improve exploratory testing with automation, Selenium IDE is an excellent choice; this browser extension for Chrome and Firefox offers easy record-and-playback features for user actions. Additionally, for those looking to scale their testing operations by running tests on multiple machines while managing varied environments from a single interface, Selenium is capable of meeting these demands as well. With such extensive versatility, Selenium not only caters to diverse automation needs but also empowers users to create custom solutions tailored to their specific workflows. Whether you are a novice or an expert, the potential of Selenium to streamline and enhance web interactions is remarkable.

The Curiosity Modeler produces precise and thorough specifications that help minimize the occurrence of expensive bugs during development. It creates test cases that are designed to identify more defects on the first attempt. Additionally, it provides compliant test data that is readily available to testers at their convenience. Users can utilize various test frameworks, whether they are open-source, commercial, or custom-built, to conduct extensive automated testing. With the ability to quickly generate flowcharts using multiple importers and accelerators, comprehensive automated tests and complete test data can be created seamlessly. Automation engineers are responsible for maintaining coded frameworks and can easily export objects and actions back to the Curiosity Modeler. This platform empowers users to automate processes effortlessly through an intuitive drag-and-drop interface, making it accessible for anyone interested in automation. Overall, the Curiosity Modeler streamlines the testing process while enhancing efficiency and effectiveness.

Software designed for ongoing performance testing facilitates the automation of API load and application evaluations. In the case of intricate applications, users can create performance tests without needing to write code. Automated pipelines can be utilized to script these performance tests specifically for APIs. Users have the ability to design, manage, and execute performance tests using coding practices. Afterward, the results can be assessed within continuous integration pipelines, leveraging pre-packaged plugins for CI/CD tools or through the NeoLoad API. The graphical user interface enables quick creation of test scripts tailored for large, complex applications, effectively eliminating the time-consuming process of manually coding new or revised tests. Service Level Agreements (SLAs) can be established based on built-in monitoring metrics, enabling users to apply stress to the application and align SLAs with server-level statistics for performance comparison. Furthermore, the automation of pass/fail triggers utilizing SLAs aids in identifying issues effectively and contributes to root cause analysis. With automatic updates for test scripts, maintaining these scripts becomes much simpler, allowing users to update only the impacted sections while reusing the remaining parts. This streamlined approach not only enhances efficiency but also ensures that tests remain relevant and effective over time.
