Why Virtualize Your API?

parallel dev & test isolated app testing app load testing sandbox API evolution

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
