The term 'Software Test' can be broken down into two parts: BETA (4 letters) and Software. BETA testing is a type of software testing that involves releasing a version of the software to a limited group of users before it is released to the general public. This allows the developers to identify any potential issues with the software and make necessary changes before it is released. BETA testing is an important part of the software development process, as it helps ensure that the software is ready for public use.
