- 8. Test execution and development Test (automated or manual) Development Your Application 3rd party APIs (virtualized) Your APIs (virtualized) • Simulate (un)expected behavior • Minimize impact on and usage of external systems • Assert usage of external components @lindybrandon

- 13. How will virtual APIs be used and managed? Local / Team / Enterprise How technical is the team that will maintain them? Scripting / coding requirements Easy to create new configurations How to incorporate in your Continuous Integration process? Redirect API calls to virtualized APIs Access control internal / external Reporting and Governance Moving from theory to practice CA Virtual API SmartBear ServiceV Mockable Apiary @lindybrandon

Editor's Notes
- Intro material How many people test web and mobile apps How many also test the APIs they rely on The importance of testing not just your APIs but how your app interacts with the API
- Third Party APIs: Can change policies and business plans on a moment’s notice How would your app respond if an API you depend on changed their policy or access
- OMG. Know what the errors look like. You may not want that in your app.
- How many of you use Facebook? How many of your parents use Facebook? My 89 year old stepfather on FB… will he understand this error?
- No! Candy Crush!!

- Functional misbehavings Functional Errors Network errors / Latency Network bandwidth Slow/fast response times
- Virtual APIs can be run locally or on a central server Let’s look at the kind of APIs you might want to virtualize – weather underground, dropbox, googlemaps, linkedin for app functionality Marketo, NetSuite for intranet apps
- Adding some real power to your virtual API – make it dynamic by hooking up a data source so you can automate your tests and run through a variety of scenarios
- Assertions and failures – decide how it should respond and then validate that
- Using Dispatch to set up some variability. For example, randomly return no data or run through a set of scenarios in a known sequence
