Relationship

• Panacea and Scapa Technologies have agreed
  jointly to develop and market stress testing
  technologies for the Remedy AR System
• The product is marketed as Scapa StressTest for
  Remedy AR System
• Panacea resells and supports Scapa StressTest for
  Remedy AR System alongside its existing product
  set

What Scapa StressTest Does

• Capture a users activity
• Generalize to a group of users
• Replay at various levels of load
• Measure response time and failure conditions
• Live on the screen or via alerts
• Post-mortem for regression testing and version
  management
• Continuous execution for SLA reporting
• Monitor system under test and underlying software
• Statistical performance data and logged events
• During tests or in production

System behaviour under increasing user load

Capture

• Scapa StressTest can record and make sense of API
  sequences between client and server
• Either
• A user performs business tasks and Scapa
  StressTest captures the traffic across an APIOR
• Scapa StressTestest interprets and sessionizes a
  continuous multiuser trace such as a log file
• Once captured, these interactions can be
  manipulated by Scapa StressTest

14
Generalization

• The automatic generation of plausible variants of
  actual user behavior.
• Allows simulation of more users than those
  actually captured
• Entire application systems can be analyzed
  thoroughly from small numbers of client machines

15
Replay

• Once the tasks have been captured generalized,
  Scapa StressTest can be employed to replay them
  at appropriate rates using sliders and other
  user-friendly controls
• The unique test management features of Scapa
  StressTest allow the dynamic modification of
  parameters such as the number of concurrent tasks
  running, the throughput of tasks, and the think
  time of tasks
• System performance data is also viewed live

16
Eclipse Extensibility - Interoperability

• Plug-in Mechanism
• Recursive Publish Subscribe Model for
  Interfaces
• Plugin interface points are declarative
  human-readable in XML
• Tool installation builds itself on demand
• Multi-faceted Interoperability/Extensibility
• User interface
• Data Models
• Team Support (version control)
• Data collection agents (monitoring etc.)
• Help system
