An Ancient World
Not for everyone
For some many of us
this is more accurate…
Our context
Do desktop applications still make sense?
IF you have to integrate with low-level SDKs
And…
IF client app requires low latency IF you have to integrate with low-level SDKs
And…
AND your stress tests look like this…
Forget Physical Laws
Test automation
with
physical devices ?!
Not great to maintain…
char[] start_scan()
char[] capture()
char[] scan_finger()
Plain Old Interfaces
byte[] start_scan();

When I capture 4 valid fingerprints
Then application is sent for approval

Forget Physical Laws Problem Automate testing of applications using physical devices
Ingredients • Common interface for similar devices
• Virtual device implementation for that interface
• Categorized test data repository
• Test data sampler
Layered World

When I capture all biometric data
And no alarms are raised
Then travel is allowed

Layered World Problem Automate testing of reusable client modules with project
customizations and specific requirements
Ingredients • Specflow (Cucumber family)
• White (GUI automation)
• Layered test code: pure UI + module + application DSL

Parallel Worlds Problem Automate testing of multiple interfaces/executions for same
scenario
Ingredients • A single test interface for the exposed functionality
• Two or more implementations of that interface
• (Basic) dependency injection mechanism
