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();

byte[] start_scan();

When I capture 4 valid fingerprints

Then application is sent for approval

When 1 finger is missing

Then emigration supervisor is called

Virtual Fingerprint Scanner

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

Reusable core modules

Application Driver DSL

Given a traveler entering the country

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

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
