- 12. Functional Test Live up to your own hype
- 13. Load Test Don’t let success kill you
- 14. Security Test Know where the dangers are
- 17. Bootstrap Parallel dev and test Test Design Virtual API Generate from spec or with tools Client Development Integration Development
- 18. Isolate Test execution and development Test Execution (automated or manual) Development Component in dev or test 3rd party APIs (virtualized) Other APIs (virtualized) Legacy Systems (virtualized) • Simulate (un)expected behavior • Minimize impact on and usage of external systems • Assert usage of external components
- 19. Performance Test Solution under test Load Test Execution (automated or manual) 3rd party APIs (virtualized) Other APIs (virtualized) Legacy Systems (virtualized) • Simulate (un)expected performance in external systems • Minimize impact on and usage of external systems • Triage Performance bottlenecks
- 20. Provide Sandbox Hardware / Software Solution API Virtual API Evaluate Integrate Integration Test
- 21. Enable API evolution… Corp Corp Web app Corp App + API API API API Device APP API Device IoT Device IoT Device API API API
- 22. Three Levels of API Virtualization Static Mocks Static responses • Semantically correct • No logic • Payloads generated from schemas or examples Code or generated from metadata Dynamic Mocks Dynamic responses • Based on input • Re-use input in output • Scripting • Data-driven / Data-generation • Simulate state Assertions on incoming content Virtual APIs Runtime behavior simulation Runtime management • Redirect traffic to Virtual APIs dynamically • Access control • Deployment • Test execution integration
- 23. API Virtualization - do you need it? • Local development & basic component testing • Requirement for sandbox environment(s) • Collaborative evolution & testing of APIs with low number of controlled dependencies Maybe • Collaborative evolution & testing of APIs with high number of complex dependencies Probably • Need for simulating functional & non- functional behavior in complex distributed solutions Definitely

Notes de l'éditeur
- Enable client development Enable test design Remove dependencies
- Functional misbehavings Functional Errors Network errors / Latency Network bandwidth Slow/fast response times
- Simulate performance in the Mock itself Simulate/model system / network behaviour Triage performance issues
- For evaluating different aspects of and API For testing integrations For simulating hardware
