Software functionality testing is run to ensure your software performs as expected across all use cases. The QA engineers validate that every feature works according to the specifications and contributes to a seamless user experience. They test functionality on every level – from individual components to complete systems. A thorough inspection allows for the early detection of issues and reduces the risk of defects in production. Software functional testing covers all environments and platforms for web, mobile, and desktop applications, as well as wearables, IoT, and more. As a result, you get reliable and intuitive digital products and services.
Functional testing in software offers solutions for different business purposes and requests. Depending on the readiness of your software, team composition, current objectives, and bigger goals, as well as available timelines and budgets, different things may work best for your project. At QA Madness, we cover a full range of QA services. That includes providing different functional testing setups that solve your current problems and help ensure efficiency in the future.
Similarly to other testing types, functional software testing ensures your users get a working and stable product. It provides insights into the quality of your software that help improve both its quality and your overall business performance. With functional testing, you can spot and fix the existing issues, learn about the potential problems, areas for improvement, and things that require increased attention in the future.
Functional testing focuses on verifying that each function of the software works according to the specified requirements. QA engineers need to look into how individual features, interactions between components, and the entire system operate in different scenarios. Hence, QA experts inspect the functionality on different levels and from different perspectives. The following levels and types of functional tests target various aspects of the software’s functionality, allowing us to investigate it in detail.
It involves verifying the input-output behavior of each feature, ensuring that it responds correctly to valid and invalid inputs. Testing each feature in isolation shows whether the overall user experience is consistent and reliable.
We check how different modules and components interact within the software product. It’s essential to ensure that everything that works correctly in isolation keeps doing so when integrated into the larger system.
It is a comprehensive, end-to-end evaluation of the entire application. We go beyond verifying the functionality of individual features or modules, focusing on the overall behavior of the software under real-world conditions.
It is typically the final step before the software is deployed to production. At this stage, QA engineers need to ensure that the software meets the end-user’s expectations and business requirements and is ready for release.
Retesting, smoke, and regression testing are performed after updates, bug fixes, or inducing new features. The goal is to ensure that changes don’t introduce new defects, affecting the features that have been working correctly.
It focuses on verifying that the user interface, content, date and time formats, currencies, and other region-specific elements are properly adapted to the target locales, making the software accessible to all intended audiences.
Quality Assurance Setup and Testing for Mobile Gaming & NFT Platform
The client was looking for a QA engineer with experience in mobile testing and knowledge of the gaming industry. They had a new and custom platform and needed to set up the QA process from scratch: define the coverage, prepare documentation, and integrate testing into the workflow.
QA Process Setup and Testing for the Meeting Platform
The product was live, but the QA process was chaotic – without a clear flow or software testing specialists involved. The client sought an external audit and process setup so that other team members wouldn’t have to test the platform and severe defects wouldn’t slip to production.

The nuances of the functional quality assurance process implementation always depend on your software’s particularities and your organization’s business objectives. Yet, in general, it is a standard five-step process that starts with planning and progresses into maintenance.
Getting familiar with your software and needs.
To begin with, the QA engineers need to hear out your requests, challenges, and expectations, as well as analyze your software. The more details you share, the better background we’ll have for further strategizing. This stage entails studying documentation and designs, interacting with software, and communicating with your team.
After gathering all the necessary information, the QA engineer will suggest the optimal coverage, preferred functional testing techniques, and a starting point for the QA setup. You can be sure it all fits in the development process seamlessly and even enhances the overall effectiveness of your development team.
Preparing testing documentation, data, and environments.
After receiving the approval to move on with the suggested plan, the QA engineer will start writing the checklist or test cases (depending on what works best for your case). Besides making the testing process better structured, these files help everyone stay on the same page and contribute to knowledge maintenance.
Also, the QA engineer needs realistic data and environments to run the tests efficiently. They can participate in the environment setup, share the requirements, and generate the test data that will enable modeling real-life scenarios.
Testing the software and reporting results.
After the arrangements above are finished, the QA engineer can proceed to the core part of the functional testing service– the tests. The expert will follow the pre-written plans, checklists, test cases, etc., to compare the actual functionality of the software to the expected–to what’s stated in the requirements.
All discrepancies, inefficiencies, logic gaps, etc., are considered defects. The QA engineer documents them, adding clear and detailed descriptions, images or videos to reproduce the defects easily, and severity explaining how critical each defect is. This information helps software developers locate the problems.
Retesting, change-related testing, and final verification.
After software engineers fix the defects, the QA specialist receives a new, improved build for a repeated check. First, they need to ensure all the defects reported at the previous stage have been fixed. Then, they check the core features once more to make sure code changes haven’t affected anything.
This phase of functional QA testing also entails more active cross-team collaborations. QA engineers don’t fix defects, but they locate the problems and help understand them better. What’s more, our QA engineers are proactive and normally share recommendations that go beyond defects, focusing on improving the overall experience.
Launching the product or deploying its newest build.
Depending on what stage your software is now, the final step can differ. What’s common in all cases is that QA engineers can join the release management process and run a quick smoke check in production.
If you work in sprints, the functional testing process starts all over again from step one, updating the objectives and test suit. If it’s a single round of testing, the QA engineer starts the functional testing and QA process from scratch when you need to inspect a new version or software product in the future.

Find the answers to queries that bother the team most frequently. If you have more specific questions related to functional testing on your project, feel free to reach out to our team at any time. We’ll be happy to share more details.
Functionality testing in software testing verifies that your software’s functions work according to the specified requirements. It ensures that every feature of the system, from the core flows and simple tasks (like submitting a form) to more complex processes (like transaction handling or user authentication), behaves as expected.
The purpose of functional testing is to validate the application’s actions and responses based on user inputs. Functional testing does not go into the backend and internal logic of the system. With these tests, QA engineers aim to ensure the software provides correct experiences.
A simpler way to define functional testing in software testing would be using an example. If we have a banking app, functional testing will check that users can log in, transfer money, view account details, and perform other banking-specific functions without errors.
Functional testing requires a structured approach to ensure that all software features are covered and inspected in detail. Functional testing companies can have a slightly different approach to managing this process. Nevertheless, the stages and activities composing this process are standard:
Functional test types focus on the functionality of the software, as opposed to nonfunctional testing types, which focus on performance, compatibility, usability, and other aspects related to everything beyond features. The classifications you can find online may differ across web resources.
Functional testing entails feature testing, integration testing, system testing, acceptance testing, change-related testing, and localization testing. These are different types of functional testing that allow QA engineers to verify the functionality and let you release high-quality software.
Functionality testing services cover a wide range of use cases, reflecting the nature of the application under test. One of the most common functional testing examples is checking the registration flow. The QA engineers look into the correctness of the registration form and mechanisms in detail, covering positive and negative cases.
They verify that a user can only register with an existing email after filling out the required fields and selecting a password that matches the set criteria. They also check whether a confirmation email is sent, whether the link works, whether the system displays the correct error messages, and so on.
By functional testing tools, we usually mean software QA teams use for test automation. They allow for efficient automated functional test creation and execution, reducing manual effort while increasing test coverage and accuracy. Functional testing tools are particularly valuable when dealing with large-scale applications that require frequent testing.
However, teams typically use other tools for functional testing: apps for test management, bug tracking, communication, and more. These are not specifically functional tools, but they are essential to the QA infrastructure.
