System Testing

Integration & System testing is the phase of software testing in which individual software modules are combined and tested as a group. It follows Unit Testing.

Testing is conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements. The purpose is to detect any inconsistencies between the software units that are integrated together. During the process, errors are discovered and removed.

The overall testing approach is defined in Integration Test Plan.

• the strategy and approach used for integrating and testing software components to build the system

• test cases to be conducted

Integration & System tests relate to, and must be traceable to the Functional Design and the User Requirements Specification.

Moreover, the system testing is an investigatory testing phase, where the focus is to have almost a destructive attitude and test not only the design, but also the behaviour and even the believed expectations of the customer. It is also intended to test up to and beyond the bounds defined in Technical Design
