A functional tester plays a substantial role in the multifaceted world of information technology. As a black box type of testing its test cases are based on the tested software’s component specifications. With its state of the art testing capabilities, the application quality of any software can readily be checked. This brings great benefits all companies working in an IT environment. How a Functional Tester Functions Through Performance Testing Automation, the functions are tested through feeding some input and checking the output that comes after it. It differs from the white box testing that considers internal program structure of a system. Functional testers validate a specific program by checking it against any given design specification. Through this test, business owners are given helpful information of the functional quality of the product or service being tested. Moreover, it allows an opportunity to detect any dangerous risks or bugs already present in the system. These ways, possible measures can be applied to lessen if not eradicate unexpected bugs that will surely cause problems in the future. Factors Considered by a Functional Tester Functional testers basically work to confirm that any system’s Application Quality meets considerable factors. One factor considered first is the system’s capacity to carry out the design and development requirements. Another factor is its ability to function according to what is anticipated out of it. Next, is its availability to be implemented with similar characteristics. Lastly, its power to reciprocate the demands of the clients. It is a functional tester’s responsibility to see to it that each of these factors are readily met by the system being tested in order to meet if not exceeds the expectation of each business owner. Steps in Functional Testing For a more favorable outcome, functional testers perform the task in a step by step process which are as follows: - The construction of input data based on the system’s function specifications
- The identification of output based on the system’s function specifications
- The implementation of the test case
- The evaluation of actual and expected outputs
It is through this organized procedure that each performance testing automation bear good fruit, all for the good of the customer’s business. The complex nature of the IT industry is truly in great need of a quality center that upholds a high standard of systems, applications and products. Thus, functional testers are always needed to keep the whole IT environment going forward.
