The Business Problem

Complex, interdependent systems wreak havoc on functional and performance testing and development efforts impacting productivity, quality and timelines

  What needs to be tested increasing – this problem is exponential   More, larger systems   Larger, complex architectures   De-coupled and evolving system components   Multiple, new devices   Extended networks

  Who is involved with software quality getting more complex   Large, distributed teams   More roles involved   Agile, iterative development methodologies

  Many moving parts   Hardware / operating system permutations   Clients / servers / databases   System upgrades / patches   Dependent 3rd party applications   Security and access control


Hardware and OS Virtualization

Virtualization and cloud technology for software testing has assisted organizations to lower infrastructure costs and offer broader access

Network

Private Cloud

Public Cloud

  Virtualization   Consolidates servers   Creates multiple execution environments

with existing resources   Provide isolated sandboxes   Centralizes configuration management

  Private cloud “can” provide self-service access to complex infrastructures

  Cloud provides incremental scalability without additional hardware


The Challenge

Simple Applications   Access to shared staged environments   Missing/changing components   Evolving deployment environments

Complex Systems   Unfeasible system virtualization (mainframes)   Systems too complex for test lab   Complex test data management across systems   Unrealistic performance from staged environments

End-to-End Transactions   Inaccessible partner systems/services   Expensive third-party transaction/access fees   Multiple “owners” of internal and external resources

Although virtualization technology has assisted to lower costs and offer access significant gaps still exists for software testing


Parasoft Virtualize

Capture Model & Provision Consume

Initiated from the system under test, the user has the ability to capture detail from a live monitor that analyzes system traffic, from analyzing transaction logs or by modeling virtual behavior within the Parasoft Virtualized interface.

After the virtualized artifact has been captured, users can now instruct the details of the virtualized asset behavior. This includes: performance, data sources and conditional response criteria. The virtualized asset is then provisioned for simplified uniform access across teams and business partners.

The virtualized asset can now be called for unit, functional and performance tests. The virtualized asset can be leveraged by any test suite – including Parasoft Test.

Leveraging application behavior virtualization the team can reduce the complexity and the costs of managing multiple environments while providing

ubiquitous access for development, test and training


Examples

  Limited access to mainframes, large ERPs, or 3rd party systems   Access is shared and must be scheduled delaying test efforts   Limited time leads to incomplete testing

  Parallel development efforts limited by system dependencies   Unfinished or evolving components delay development cycles   Multiple application versions makes environment management time consuming

  Capacity Constrained staged environments   Staged environment has limited capacity constraining realistic performance tests   Staged environment test databases shared and corrupted

  Complex, time consuming test data management   Data management for complex systems time consuming to manage   Permutations of environments and test data complex to manage

Parasoft Virtualize is used throughout the SDLC to eliminate constraints and reduce the costs of managing development, test and performance environments


Parasoft Virtualize – Limited Access

Shared Mainframe

System Under Test

Multiple development and test teams have limited access to mainframe cycles. Access time is shared and tightly scheduled.

Summary

  Limited access   Reduce transaction and infrastructure costs   Avoid delays due to ‘scheduling conflicts’ or dependency on 3rd party

schedules

  Parallel development   Provide faster time to market for agile business needs   Avoid ‘Waterfall waiting’ and validate functionality sooner

  Capacity Constrained   Build scalable performance into system components   Avoid potential conflict with the ‘real’ back-end systems

  Data management   Reduce data administration costs and   Reduce time to validate use-cases by simplifying data requirements

Reduce the costs throughout the SDLC to by eliminating system and environment constraints
