Learn how Parasoft service virtualization helps teams test earlier, faster, and more completely. Covers service virtualization for Agile development, service virtualization for load/performance testing, service virtualization for eliminating test constraints.

1. Parasoft Virtualize
Eliminate system and environment constraints

2. 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

4. The Challenge
Although virtualization technology has assisted to lower costs and offer access
significant gaps still exists for software testing
Simple Applications
 Access to shared staged environments
 Missing/changing components
 Evolving deployment environments
Bus
Complex Systems
ERP
 Unfeasible system virtualization (mainframes)
 Systems too complex for test lab
 Complex test data management across systems Bus
 Unrealistic performance from staged environments Partner
Partner
End-to-End Transactions
 Inaccessible partner systems/services Cloud Resource Bus
 Expensive third-party transaction/access fees
 Multiple “owners” of internal and external resources

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

7. Parasoft Virtualize – Limited Access
Multiple development and test teams have limited access to mainframe cycles.
Access time is shared and tightly scheduled.

8. Parasoft Virtualize - Parallel Development
Software changes are delayed due system dependencies. Parallel development
activities are stifled, waiting for access to dependent functionality.
