SOA Testing
  • AIX development environments connect to development mainframe systems
  • No equivalent flash copy test systems
  • Use the ‘offline leg’ instead
  • DR “Mega test”
    • Connects offline leg to flash copy systems
    • Reduces production resiliency
    • Requires cross platform coordination, skill sets, etc
    • Still tests only a small percentage of applications

soa testing1
SOA testing
  • Development systems are production
  • Developers geared towards testing new stuff
  • Development work has business sponsorship
  • Software upgrades seen as ‘keeping the lights on’
  • What is more important?
soa testing2
SOA testing
  • Application reuse is good but
  • People writing code don’t know what they are driving on the mainframe
  • Difficult to get/find the right people for an application
  • Errors are difficult to diagnose
  • Especially true for out of hours testing
