Delivery Process: ENG.9 System integration test

The purpose of the System integration test process is to integrate the system elements to produce an integrated system that will satisfy the system architectural design and the customers’ expectations expressed in the system requirements.

As a result of successful implementation of this process:

ENG 9.1 a system integration and system integration test strategy is developed for system elements consistent with the system architectural design according to the priorities and categorization of the system requirements

ENG 9.2 a test specification for system integration test is developed to verify compliance with the system architectural design, including the interfaces between system elements

ENG 9.3 an integrated system is integrated as defined by the integration strategy

ENG 9.4 the integrated system elements are verified using the test cases

ENG 9.5 results of system integration testing are recorded

ENG 9.6 consistency and bilateral traceability are established between system architectural design and system integration test specification including test cases

ENG 9.7 a regression strategy is developed and applied for re-testing the system elements when changes are made

NOTE: For software and systems test documentation, the IEEE-Standard 829-2008 might be used.

NOTE 1: The test specification for system integration includes the test design specification, test procedure specification and test case specifications.

NOTE 2: The test results for system integration include the test logs, test incident reports and test summary reports.
