Best Functional Testing Software

Functional testing is the process of verifying that an application, website, or system performs its intended functions correctly. It checks if the software works as expected based on the specified requirements and meets the needs of the users or business.

During the planning phase of a project, a document is created that lists all the functional specifications or requirements. This document outlines what the application, website, or system is supposed to do from the user’s perspective.

The main goal of functional testing is to validate that the software system’s features, capabilities, and interactions with different components are working properly. It involves testing various aspects, such as user inputs, outputs, data processing, user interactions, and the system’s behavior under different scenarios and conditions. Functional testing focuses solely on confirming that the system functions as it should, according to the defined requirements.

In essence, functional testing ensures that the software being developed or updated meets the intended functionality and provides the expected results, satisfying the needs of the users or business.

To qualify for inclusion in the Functional Testing category, a product must:

  • Provide tools and frameworks for testing the functionality of software applications, websites, or systems.
  • Support the creation and execution of test cases based on functional requirements or specifications.
  • Enable testing of user inputs, outputs, data manipulation, user interactions, and system behavior under various scenarios.
  • Offer reporting and analysis capabilities to identify and track functional defects or deviations from expected behavior.
  • Integrate with other testing tools and frameworks, such as unit testing, integration testing, and test management solutions.

By conducting functional testing, organizations can ensure that their software products meet the specified functional requirements, operate as intended, and provide a satisfactory user experience.

FAQs of Functional Testing Software

Functional testing is a testing method aimed at verifying whether each application feature operates in accordance with the software requirements. Each function is evaluated against its corresponding requirement to ensure that its output aligns with the end user’s expectations.

UFT One, formerly known as Micro Focus UFT (Unified Functional Testing), is a widely-used testing tool for automating functional tests across web, desktop, mobile, and mainframe applications. It allows users to efficiently navigate through the interface as well as the service and database layers.

Functional testing is typically conducted as black-box testing, meaning the internal program structure is disregarded, unlike in white-box testing. It assesses compliance with functional requirements and is sometimes part of the quality assurance (QA) process. Functional testing is distinct from acceptance testing.

Selenium facilitates Functional Testing, according to its official website, supporting such testing at both the System Testing Level and the Acceptance Testing Level of the Software Development Life Cycle. Selenium automates functional tests at the UI layer of the web application being tested.

For example, consider a restaurant requiring an app for customers to order at their tables without a server. The developer would create a unit test to assess the “add to order” function. Similarly, other individual functions like “remove from order” or “submit order” would also undergo unit testing.
