RE-THINKING PERFORMANCE

TESTING

CATEGORIES

Performance

Load Stress

• Not for finding bugs• Response/Interaction

times• Profiling• Planning & forecasting• Infrastructure decisions

• Identifying limits• Identifying load

characteristics• Planning & forecasting• Infrastructure decisions

• Identifying app behaviour outside boundaries

• Identifying graceful handling strategies

• Planning & forecasting• Infrastructure decisions

DESKTOP APPS• Do not have multiple users accessing

simultaneously

• Reduced network consideration

• Reduced shared resource consideration

• Data store can be co-located

• Common expectations around response of native applications

• Testing requires different approaches

METRICS

ADVANTAGES• UI finicky-ness eliminated

• Relevant performance numbers gathered

• Fluff reduced

• Easier to maintain

DISADVANTAGES• Code intensive

• Requires significant dev involvement

• UI-Presenter hook-up performance might be missed

• Over-enthusiastic test-optimisation might skip vital layers
