Most businesses today rely on software for the efficient running of their business. Most businesses that use software continually develop and enhance their applications on a regular basis to ensure that business processes run smoothly and effectively. For this reason, it is important to continually test the function of new and developing applications to ensure that it is doing the job required. Functional testing of software essentially involves testing the software to ensure that it does what it was designed to do.
Five Stages of Functional Testing
There are five stages of functional testing which include the following.
The functions that the software is expected to perform are clearly identified and laid out.
Information based on exactly how the software is expected to function is created.
The expected output is determined based on the input data.
The function test is carried out.
The actual function is compared to the expected function based on the output.
Hire a Professional
Assuming you hire a professional to carry this out for you, usually, test engineers will look at the application and develop a fully comprehensive test plan including all of the functions and areas to be tested. Functional testing is usually done towards the end of the software development cycle; however, experts say that functional testing should be done at all stages of development. Even at the earliest stages, individual components of the system can be tested and result extrapolated to the entire system. Functional testing across the life cycle of the application can confer significant advantages in terms of the overall quality of the application and can potentially help to reduce maintenance costs, which can be expensive.
Other Types of Software Testing
Functional testing is not the same as performance testing or user acceptance testing. User acceptance testing looks at the difference between what the application is designed to do and what the end user actually wants. Performance and scalability testing look specifically at the performance of the application under a variety of conditions and function testing compares the actual function of the application to what the design specifications were. With functional testing, while some users may be prepared at least in the short run to accept certain function failures as long as the software does what they want it to do, other users may rely heavily on the software for a function which has very specific legal and business ramifications and for this reason, can not afford for the function not to match the design specifications.
Conclusion
All forms of software testing are of vital importance to businesses as they rely so heavily on software systems for most business processes. Software testing should be done at all stages of the application life cycle from development to implementation and as any changes and updates are made. Functional testing specifically is important to business because it is important that any software used actually does what it was designed to do. In some cases, the design of the software is so specific to your business that you literally cannot afford to have any function failures. Ensure you speak to a qualified professional to discuss all of our software testing needs.
