It-testing tas-software għandu diversi livelli (skond l-iskop) u tipi (skond l-għan). Ħadd tifhem — unit, integration, end-to-end; functional vs non-functional — jgħin biex tibni approċċ ta' testing kompletu li jkopri aspetti differenti tal-kwalità.
Livelli ta' testing (skond l-iskop)
UNIT → individual functions/methods in isolation (smallest, fastest, most numerous)
INTEGRATION → multiple units/components working TOGETHER (e.g. code + database, services)
END-TO-END (E2E) → the WHOLE application from the user's perspective (full flows,
through the real UI/system) — broadest, slowest
SYSTEM → the complete integrated system; ACCEPTANCE → meets business requirements
