How to Ensure Software Quality through Functional Testing?

Functional testing process ensures that the underlying code of a software works as expected. It basically involves testing the application’s interface to ensure that the application is meeting all user expectations.

Different Kinds of Functional Testing Includes:

Why is Functional Testing Required?

Functional testing lies in the middle of all testing strategies. Functional testing holds key in ensuring the product’s functionality as per user expectation. By performing functional testing early in the development phase, one can ensure that each component is working correctly as expected. This process should be continued throughout the development cycle and into production.

For an e-commerce application, each feature must be tested first. It includes, adding items to cart, providing credit card information, and more. Once the interaction flows are completed, functional test must be included thereafter.

Running Functional Tests

Functional testing can be performed using both manual tests and automation testing tools. Functional testing can be simply performed by executing manual testing, which involves testing the product as per user’s expectation. However, functional testing could be time-consuming and at times can hamper developing new features like product quality and UX.

Black-Box and White-Box Testing   

Black box or interface level testing involves a user interface to execute functional and regression tests. It includes functional tests, regression tests, and UI tests.

White box or code level testing is done at the code level to find bugs and errors. It includes unit tests and load tests.

Coming to the automation tools, Selenium and Watir are commonly used to perform functional and regression testing. However, it might not complement the functional testing every time. Moreover, it can take up to 10 time longer time to setup as compared to manual tests. Here, maintenance could be challenging, especially when the product is still in development phase. Moreover, with the product changing more frequently, automation tool can’t emulate the exact user experience.

With expert and qualified testers on board, 360logica has an exemplary track record in providing functional testing to clients in retail, IT, telecom, e-commerce, e-learning, manufacturing, finance, healthcare, travel, technology, and other sectors. We formulate a robust approach and personalized test plans to ensure all prerequisites are met according to the application as expected. We are adept in using a variety of licensed and open source tools, which help reduce the cost of testing. Moreover, test automation techniques allow us to create interfaces for low cost regression testing before and after deployment of software products. Our expertise in using the personalized selenium automation framework guarantees high-quality open source testing of applications and improved integration and compatibility testing. The website testing phase includes running the application on different browsers and propositions to improve its compatibility and ensuring robust functional features.
