Testing is very important. Not only to prevent and debug annoying bugs, but it also helps project newcomers to better understand the expected functionality of your functions and classes.
Software testing consists of verifying if the actual software product meets the expected requirements and guarantees us that the software product meets the quality standards to be released correctly. It involves running software / system components using manual or automated tools. The purpose of software testing is to identify bugs, gaps, or missing requirements compared to actual requirements.
Software testing is important because if there are any bugs, they can be identified early and can be resolved before the software product is delivered. The proven software product guarantees reliability, security and high performance, which translates into time savings, profitability and customer satisfaction.
The Software Testing Life Cycle (STLC) is a sequence of specific activities that are carried out during the testing process to ensure that software quality objectives are met.
Software testing is not just a single / isolated activity, i.e. testing. It consists of a series of activities that are carried out methodologically to help certify your software product.
There are the following six major phases in every Software Testing Life Cycle Model (STLC Model).
