Questions


National Defense Industrial Association states that Software Testing In The Cloud (STITC) is an area that will grow in importance in the next few years

STITC is an emerging discipline that has potential to significantly change the way testing is done

STITC lies at the intersection of software testing, cloud computing, and system migration, and canbe divided into three facets: Testing IN, OF, and TO the Cloud

Introduction


The cloud provides ubiquitous, on-demand access to computing resources “as services” via Internet

Software-as-a-Service | Google Docs, Office Web Apps

Platform-as-a-Service | Google App Engine, Windows Azure

Infrastructure-as-a-Service | Amazon EC2, Rackspace

Background CLOUD COMPUTING


Creating abstract computing resources from more powerful physical resources

Background VIRTUALIZATION


The process of operating software under specifiedconditions, observing the results, and making an evaluation of the software. [IEEE 610.12 Std.]

Testing is the primary means of validation used in the software industry, and can account for as much as 50 to 75 percent of software development costs

Automating the testing process is not an easy task but can have long-term benefits: Reduced costs, time, and risks Increased coverage

Background SOFTWARE TESTING


What makes cloud-based applications easier or more difficult to test than conventional applications during development and maintenance?

Motivation TESTING OF THE CLOUD

Cloud Testability

Impact on Application

Development


Dark Side of Cloud Testability

Remoteness

InformationHiding

Complexity

Statefulness High Dependability & Performance Requirements

Autonomy

Paradigm Infancy


Bright Side of Cloud Testability

Computational Power

Storage

Testing requires lots of resources and the cloud is certainly powerful enough to handle it

Virtualization


Test Support as-a-Service (TSaaS)

Provider A and B in a Cloud Community Expose TSaaS to Provider C


TSaaS Development Methodology

Describes How To Extend Existing Test Automation To Develop TSaaS for Partners


Major Components of the TSaaS Architecture

TSaaS Architecture


Designed for the Windows Azure Cloud Platform

TSaaS Prototype PROOF OF CONCEPT


Building the prototype established the feasibility of TSaaS development but still much work to be done to evaluate the proposed testing approach

Seeking to apply TSaaS in the context of a real world problem where various aspects of the approach would be practically useful Collaborative or “Community Cloud” Testing plays a central or vital role Benefit from virtualization or simulation

Possible cloud or testing projects for consortium.
