System testing during development integrates components to create a version of the system and then tests the integrated whole. Which of the following are key differences between system testing and component testing? Select all that apply.

Components developed by different teams may be integrated at this stage

System testing focuses only on functional requirements, never non-functional ones

System testing in some companies involves a separate testing team with no involvement from designers and programmers

System testing is a collective process, whereas component testing is an individual developer process

During system testing, reusable and off-the-shelf components may be integrated with newly developed components

Correct Answer

(1) During system testing, reusable and off-the-shelf components may be integrated with newly developed components

(2) System testing is a collective process, whereas component testing is an individual developer process

(3) Components developed by different teams may be integrated at this stage

(4) System testing in some companies involves a separate testing team with no involvement from designers and programmers

Explanation

System testing differs from component testing in two key ways: (1) reusable and off-the-shelf components are integrated with newly developed components for the complete system test; (2) system testing is a collective process - components from different team members or subteams are integrated, and some companies use a completely separate testing team.
