System Test Results

System testing (also known as Integration testing) is a logical extension of unit testing. Two or more units that have already been tested are combined into a component (or a subsystem) and the interface between the units is tested. The goal of System testing is to ensure that all interacting units and subsystems in a system are interfacing correctly with one another to produce the desired results. System tests will also ensure that the introduction (or removal) of one or more units or subsystems into the system does not have an adverse affect on existing functionality of the system as a whole. A system test covers the testing of interface points between units and subsystems. System testing is performed once unit testing has been completed for all units contained in the subsystems being tested. System testing identifies problems that occur when units are combined. Since units were individually tested prior to combining (integrating) them, any errors discovered when combining units are likely related to the interface between units.

The ministry's ADE process requires that System testing is done on all the subsystems and the whole system (application) before the request for promotion of the whole application to UAT is considered. To this effect, the development teams are required to submit the following to the Ministry configuration management team or Middle Tier team along with the request for promotion :
