System Testing

What is System Testing?

System testing validates the complete, fully integrated application against the specified requirements, testing end-to-end functionality in an environment that closely resembles production.

Key Characteristics

• Performed after integration testing is complete, on the whole system as a black box.
• Verifies both functional and non-functional requirements (performance, security, usability).
• Typically conducted by an independent testing team.

What System Testing Covers

• End-to-end business workflows.
• Compatibility across environments.
• Data integrity across the entire application.
