What is black box testing used for?
Any software system or application can be tested with black box testing. It is simply a process of interacting with a system with the intention of determining how it works in certain scenarios with certain expectations. There are three main types of black box testing, which include:
Functional testing: Software testers conduct this type of black box testing to ensure that a system meets its functional requirements.
Non-functional testing: Non-functional testing examines performance, scalability, and usability requirements rather than functionality.
Regression testing: This testing of the impact of new code on existing code is done after code fixes, upgrades, or any other system maintenance.
In short, black box testing is a simple process that helps us decide whether a piece of software works or not. Particularly so, whether it works in the way our users would want. It isn’t too much more complicated than that and, in fact, you don’t need much software development experience to engage in black box testing. You might even have done it before without realising it.
For any software development company, black box testing will be a continuous process throughout a software development project. There may be in-house testers who deal with the tests, or they may be conducted by people in other roles, including developers, project managers, and business analysts. It should be a process happening throughout an entire project to ensure that the software being built works properly and works with a specific intent for a target user.
