Validation testing is the process of verifying that a software system meets the requirements specified in the system’s specification. Validation testing is also known as system testing, software testing, or software assessment.

Validation testing is an important step in the software development process. It helps ensure that the system meets the requirements specified in the system’s specification. Validation testing also helps ensure that the system is working as expected.

Validation testing can be divided into two types: functional and non-functional validation.

Functional validation tests the system’s functionality. It tests the system to see if it can perform the required tasks.

Non-functional validation tests the system’s usability. It tests the system to see if it is easy to use.

Validation testing can also be divided into multiple stages.

The first stage is system development. This is when the system’s specification is created.

The second stage is system testing. This is when the system is tested to see if it meets the requirements specified in the system’s specification.

The third stage is system evaluation. This is when the system’s performance is evaluated.

The fourth stage is validation testing. This is when the system is tested to see if it meets the requirements specified in the system’s specification.

Validation testing is an important step in the software development process. It helps ensure that the system meets the requirements specified in the system’s specification. Validation testing also helps ensure that the system is working as expected.
