Functional testing and non-functional testing are the two basic types of software testing. Another sort of general testing is termed maintenance testing.
The primary goal of alpha testing is to ensure bug-free functionality. Beta testing entails distributing the software to a small group of genuine users. They can do whatever they want with it. To put it another way, this testing is not structured.
An explanation. The process of discovering faults in a developed product is known as software testing. It also determines whether the actual results match the predicted outcomes and assists in the detection of faults, missing requirements, or gaps. Testing is the last phase before a product is released to the market.
The program is tested by giving it input and then examining the outputs to see if they conform to the functionality it was designed for. Software is functionally tested on a comprehensive, integrated system in order to assess the system's conformance with its set requirements.
