QA & Software Testing
Rapidly changing IT has necessitated the need for high-quality and stable products. To deliver quality products to customers’ enterprises adopt various software testing practices. Among the various software testing methods, functional testing is one of the most important testing methods. Let us now try to understand some of the best practices of this testing method in detail.
What is functional testing?
It is a black box type of software testing method that is performed to validate the functionality of the software. The main purpose of this test is to check each functionality of the application by providing certain inputs and validating the outputs against the functional requirements. It is also known as specification-based testing as it is completely based on program specifications. This test checks User Interface, APIs, Database, Security, Client/Server communication, and other functionalities of the application.
Why functional testing is performed?
Here are some of the reasons that depict the need for this testing
What are the best practices of functional testing?
Here are some of the best practices of this testing method:
Gather all information and plan the test: Before starting the test all teams must have a proper understanding of what is to be tested and what strategy is to be followed.
Prioritize the test cases: Prioritize the test cases based on difficulty levels and write test cases early in the requirement analysis and design phase.
Write reusable test cases: Test cases take a lot of time and expertise to work on. So having reusable test cases is beneficial to save time. And, to create reusable test cases, plain language should be preferred as it makes the process quick and tests are easy to execute.
Test early and test often: Early testing helps in the early identification and fixing of defects in the initial phases of SDLC. Also, the software should be tested often with the help of the regression testing method to ensure that any recent code changes do not affect the existing functionality of the software.
Automate wherever possible: Automation helps teams to save time and money, however, it should be noted that 100% automation is a myth. Thus, testers should segregate the test cases that can be automated and that need manual testing to ensure a smooth testing process.
Centralize data storage system: By centralizing the data store system, data will be available to all team members and can be referred by anyone at any point in time. It will eliminate the chances of repeated data, report, or errors that occur due to a decentralized data system
Create a traceability matrix: To capture all requirements provided by the client, it is necessary to create a traceability matrix and it maps the user requirements with the test cases. Providing coverage of all functionalities when conducting software testing is beneficial.
Conclusion: A fully functional product that works as expected and delivers seamless UX to customers is needed by every business. To achieve such a product functional testing plays an important role. It works as an integral part of a software testing and quality assurance process and tests the end-to-end functionality of the software. Leverage functional testing from a next-gen QA and software testing services provider to get high-quality software.
