Slide 2:
Challenge
Core API considered “already stable”, but increasing number of dependant services eroding confidence
System needed enhanced security, performance and functionality testing mechanism
Core API in the critical path for each OS release, further delaying multiple individual projects Harbinger Solution
Deriving valid and invalid data for API parameters by subjecting API to parameterized analysis through equivalence class and boundary values
Innovative elimination strategies to reduce the exploding number of parameter combinations
White box analysis phase to ensure that all possible code execution paths are covered
Execution phase included writing a data-driven test harness to abstract test data from API and API from result validation Benefits
Excellent set of methodically derived test cases for security, performance and functionality testing
Test harness separates out dependencies between different teams and projects
Significant improvement in development and release speed of services
Core API library being built and tested independently and without being slave to uncertainties around future of OS services BOTTOM LINE
Company growing its Operating System services backed by a robust testing mechanism in place for its core API DATA-DRIVEN TESTING FOR OS API www.harbinger-systems.com Situation
A leading Operating System vendor with a growing number of OS services
Increasing number of services leveraging core API library of the Operating System
