Functional Testing is arguably the most important aspect of a good quality assurance process, since it ensures that the application in question does what it was designed to do.
It is often recommended to implement Functional Testing at the beginning of the software development life cycle (SDLC).
However, it is never too late to start improving your application’s functionality, especially if noticeable problems start to arise. After all, substandard functionality means that users have a poor-quality experience and can severely reduce customer satisfaction.
Functional testing can involve black box testing, streamlining the user interface, checking security, shoring up connectivity to APIs and databases, improving client/server communication, and several other functionalities.
Much of this testing is automated but can also be carried out manually for more in-depth results.
Simply put, Functional Testing helps you avoid:
- A poor user experience for customers, employees, and other end users.
- Flaws in the system’s functionality that create security risks.
- Users receiving unexpected outputs and having to contact customer service, or even abandon the application altogether.
- False form errors and inaccurate website information.
Many companies adopt Agile/DevOps models in order to optimise their speed and quality when delivering business value. Test automation plays a crucial role in those processes.
Testing
Our Functional Testing spans the following aspects:
- System Testing
- Accessibility Testing
- Error Conditions Testing
- Unit Testing
- Smoke Testing
- Sanity Testing
- Integration Testing
- White box Testing
- Black Box Testing
- User Acceptance Testing
- Regression Testing
Methodology
Our methodology is simple and straightforward. We first need to understand the requirements. Then, based on those requirements, we identify test data. From there, we need to compute the expected outcomes with selected test input values, and then execute test cases. Finally, we compare the actual and computed expected results.
As for individual types of Functional Testing, our System Testing provides independent, on-demand verification of your software on the platforms, browsers, and devices your customers / employees will be using.
Similarly, User Acceptance Testing validates that a system works well for users with respect to their needs, requirements, and business processes.
Functional Testing is frequently automated and makes use of our innovative Accelerators. For example, our specialised BA360 Accelerator was developed to accelerate the Manual Testing process with black box, white box and exploratory testing techniques.
Our trained and experienced Functional Testing Consultants work with you and your users to help identify any problems. Our services are delivered through our team either on-site, off-site, or offshore, depending on your needs. Our experts will empower you with the confidence to embrace change fully.
