Function Testing

Definition - What does Function Testing mean?

Function testing is a form of quality assurance that tests various industrial systems in order to verify functions, programs, tools and other components by checking them and comparing to a designated specification, design, document or program.

In function testing, it is vital to identify the functions, create inputs, and determine outputs based on various specifications. It also consists of a comparison of the expected and tangible results to determine whether a certain function works accordingly.

Corrosionpedia explains Function Testing

Function testing is usually carried out by a test engineer in order to identify processes that would analyze particular equipment, products and other components in areas such as quality assurance and manufacturing. This form of testing is also beneficial in assuring that products meet the desired specifications to avoid issues such as damage and corrosion, among other things.

Test engineers are in charge of ensuring that the test covers all the major components of industrial elements and components under process. This type of testing is vital, especially in the design phase. This method guarantees that products, systems, etc. are designed to meet the expected outputs.

Through efficient function testing, all components that are required within a unit can be adequately tested according to its proposed design. This reduces the incidences of future issues like re-designing, adding additional functions or components, damage or failure, which could boost costs and cause delays. Early detection and management can help supervisors and operators improve performance and prevent issues that may arise in future operations.
