How to enhance product’s quality and prevent risks with functional testing

Before launching a new product on the market, it must pass through a vital functional software testing phase in the software development lifecycle. This phase ensures that the product meets quality criteria and business requirements. In terms of software testing, functionality includes all actions performed by the application, accessibility features, user interface features, APIs, and error conditions. With functional testing services, you can not only ensure that quality requirements are met but can provide consistent software functionality and a smooth user flow. Let’s discuss the basics of how to achieve these goals.


What is functional software testing?


The QA team conducts functional software testing to verify that the actual software features align with the product specifications. This helps testers determine that the software performs its intended functions and check if feature updates affect existing functionality. In other words, functional testing allows QAs to verify that the software does what it’s supposed to do in actual use.
Based on written test scripts and user scenarios, testers enter relevant data when testing a specific feature to check its results against functional requirements and verify ease of use and absence of defects. For example, when a user selects items to buy, do they show up in the shopping cart? With functional testing, you can check what the software do and whether it meets the documented functional requirements.


Benefits of functional software testing

Functional software testing is part of pre-release preparation, serving as the basis for a quick return on investment and desired business results. The critical benefits of functional testing services include:
● Enhanced product quality. When you can avoid potential functionality issues with your product early in development, the quality of your software grows, creating a positive company image.
● Increased customer satisfaction. Undoubtedly, the fewer errors your users encounter while interacting with your product, the higher their satisfaction.
● Predictability. Your QA team can reduce the risk of failed software releases and, in turn, reduce the chances of rework and decrease overhead.
● Meeting user and business expectations. While requirements may change throughout a project, functional testing services can help you ensure that your product meets expectations at all stages.
Challenges you can solve with functional testing
When testing software functionality, you can anticipate potential pitfalls and solve the following problems at the same time:
● Incorrect functionality. By running test cases and various user scenarios, your team can verify that the product works as expected and meets software requirement specifications (SRSs) early in the software development lifecycle. Thus, you can fix issues in functionality and save resources in one go.
● Poor system functioning. Your team can execute test cases to understand how functionality works under normal conditions with functionality testing services. This prevents low efficiency or poor system performance.
● System behavior gaps. A QA can discover software behavior gaps in user interface elements, user acceptance, or APIs by applying functional testing.
● Confusing software logic. Functional testing makes it easier to identify and fix bugs related to the logic of your software in a real environment.
● Poor UI decisions. UI elements are the visible components of your application that users frequently interact with. For example, testing menu bar functionalities, menu items, error messages, and buttons allows testers to verify that they display correctly.

Functional testing services are provided by software companies with the following efficient workflow:

  1. Gather and analyze product requirements. This step involves gathering business requirements and the product’s functional requirements and preparing a test plan. The test plan includes all information about how your software will perform certain functions and all major software features, accessibility, and error conditions that need to be tested.
  2. Prepare input values and specify expected values. Based on product requirements, the QA team creates entry criteria for each specified test object and defines exit criteria accordingly.
  3. Write and execute test cases. When writing and running test cases and various scenarios for the selected test object, testers can use automation tools or perform manual testing.
  4. Compare the input value with the output result after each test is completed. After executing tests, testers collect the results to analyze them and verify compliance with technical requirements and compatibility with various environments.
  5. Log defects, if required. Based on the test results, your development team can generate a report with all detected functional errors and ask developers to fix them.
    Conclusion
    Using functional testing services, you can be confident that your end users will receive software with the expected quality that functions reliably. In turn, this will help you avoid pre-release bottlenecks and save money and time. High-quality software functionality and a flawless user flow will help your business achieve market excellence while increasing your company’s value in the highly competitive software industry.
