project planning - What do people mean when they say (and write) lifecycle testing? -

-

i've been current company 4 months , i've noticed how several of our rnd scopes/documents use term "lifecycle testing."

i've thought term mean entire testing phase of project, context of term suggests instead when software tested "live" or "real" data in staging environment close production environment possible.

this has led me wonder if have misunderstood meaning of phrase, in case, can explain lifecycle testing supposed or mean?

a lifecycle of software it's behaviour in following situations:

  • startup. load correctly? fast @ startup? (depends on kind of software)
  • mid-life. use memory? clean memory? it's ought do?
  • exeting. cleanup resources correctly? closes down well?

lifecycle testing important server applications, it's focussed on "mid-life" (it's not official term btw). server apps may never crash while doing importantly, , if do: shouldn't bring down complete system.

the clue "lifetime" of being "live" or "real" isn't true, it's more being "alive" "live".

for instance; i've build flash client-application "billboard" application, displayed @ large screen, , lifecycle-testing it:

  • graphics, show well? not first minutes, 12 hours without restarting app.
  • auto-update, work?
  • etc.
