Software validation is the process of checking that a software system meets its specifications and requirements. It is a crucial step in the software development lifecycle, as it helps to ensure that the software is fit for purpose and will perform as expected.
Software validation is important because it can help to prevent defects from being released into production. Defects can cause a variety of problems, including system crashes, data loss, and security breaches. By validating software before it is released, organizations can reduce the risk of these problems occurring.
There are a number of different techniques that can be used for software validation, including:
- Static analysis: This involves examining the source code of the software to identify potential defects.
- Dynamic analysis: This involves testing the software in a live environment to observe its behavior.
- Manual testing: This involves manually testing the software to verify that it meets its requirements.
The choice of which validation techniques to use will depend on the specific software system and its requirements. However, it is important to use a combination of techniques to ensure that all aspects of the software are thoroughly tested.
Software Validation
Making sure software meets its requirements is crucial. Here are key aspects of software validation:
- Verification: Checking if software meets specifications.
