Delivers Software Applications, Platforms and Infrastructures as services over Web

Like conventional applications, but hosted and deployed in a cloud environment Helps end users perform a specific task Provides ubiquitous access applications and user data New application services can be developed by tailoring existing cloud services

What makes SaaS more difficult or easier to test than conventional applications during development and maintenance? Cloud Testability Impact on Application Development

Remoteness Information Hiding Complexity Statefulness High Dependability & Performance Requirements Autonomy Paradigm Infancy = Grand Challenge

Deployed in an Environment Characterized By… Computational Power Storage Virtualization Testing requires lots of resources and such an environment facilitates test execution

Providers A and B Expose Test Support as-a-Service to Provider C

Test Libraries Test Initialization Test Data Test Cleanup

Preconditions Assertions Inputs

Successful implementation of the prototype validates the TSaaS development method Merely lays the foundation for investigation into the overall approach Major factors to success were test case parameterization technique, and runtime virtualization support through Hyper-V API Technical difficulties: Combination of runtime virtualization, testing, and development

Much work still needed to evaluate overall testing approach Must deploy TSaaS to the cloud and perform controlled experiments Prototype has been build in a manner that streamlines moving it to Windows Azure Install Windows Azure SDK and prerequisites Configure Baseline VHD using Azure SDK Migrate SQL Server 2008 R2 Data to SQL Azure
