Common Types of Automated Testing ,[object Object],[object Object],[object Object],[object Object],Functional Testing (via UI, API, Web Services… ) Component- level System- level Integration- level

Hybrid Test Automation Framework ,[object Object],[object Object],[object Object],[object Object]

Framework Type Recommendations ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Keyword-driven Takes the most effort to evolve and thus requires the most investment with design & implementation ,[object Object],[object Object],[object Object],[object Object],Hybrid ,[object Object],[object Object],[object Object],Data-driven Cons Pros Framework Type

Test Execution Phase ,[object Object],[object Object],[object Object]

Service Oriented Architecture ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],After SOA Application A DB Application B DB Application A Presentation Layer Application A DB Before SOA (3-tier architecture) Application A Biz Logic Layer Application B DB Application B Biz Logic Layer Application A SOA Services Application B

Web Service versus GUI-based Testing ,[object Object],[object Object],[object Object],Consuming Client GetWeatherInfoByLocation (‘Atlanta’,‘MA’,’Mexico’) Web Service ???

Challenges Testing SOA ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Layered Testing Approach ,[object Object],[object Object],[object Object],[object Object],[object Object]

Automating Testing of Web Service Components HP Service Test (WSDL-Generated TCs) Inbound Request Service Operation under test Ex: NameandAddress Service 1 ,[object Object],[object Object],[object Object],addressValidation 1 2 Outbound Response 2 Emulated Service Subscriber Or Calling Client Web Service Operation under test 3 3 Test/Defect Management System HP Quality Center Test Exec Result Log Validate

Methodology to Reduce Test LifeCycle and Accelerate Parallel Development - iTKO VSE DELAY Web Services (under construction) Time Time Front-End Dev & SOA Test Teams DELAY Back-end under development/ 3 rd Party Service dependencies Virtualized Web Services based on WSDL Web Services DEV & TEST Teams Web Services DEV Team Front-End Dev & Web Service Test Teams VSE Before After VSE

Calculating the ROI Time Cumulated Costs ($) Initial Investment Automated Testing Manual Testing Cumulative Cost Saving ROI= Net Value / Investment Cost * The maintenance cost of TA is usually not trivial but if you keep enhancing your TA framework, improve application testability and overall testing processes high ROI is very much achievable
