What is System Testing?
System testing is a crucial stage in the software development lifecycle that aims to validate the complete and integrated software solution. It is a type of black-box testing that focuses on verifying the functional and non-functional requirements of the system as a whole.
Objectives of System Testing
- Ensure that the software meets the specified requirements and functions as intended.
- Identify defects or discrepancies before the product is released to end-users.
- Validate the overall system performance, reliability, security, and compatibility.
Types of System Testing
- Functional Testing: Focuses on verifying that each function of the software operates in conformance with the requirement specification.
- Non-functional Testing: Assesses aspects such as performance, usability, and scalability.
- Regression Testing: Ensures that new code changes do not adversely affect existing functionality.
Importance of System Testing
System testing serves as the final verification step before deployment. It allows teams to ensure the complete system is working correctly in various environments and under different conditions, reducing the risk of software failure in real-world applications.
