Public Test Environments (PTE)

What is a PTE?

Public Test Environments are publicly available builds for testing upcoming changes prior to release as a stable build.

A PTE can contain any of the following:

  • fixes
  • enhancements
  • new features
  • new content
  • new units

With the transition to a modern toolchain there will be two PTEs available:

  • Legacy Public Test Environment (32 bit, older operating systems, etc)
  • Modern Public Test Environment (64 bit, modern operating systems, etc)

Clean Testing with Multiple Copies of PA

You can start multiples copies of PA using the --localstorageurl command line option with a different name for each copy:


This can be used to separate testing from your stable build and is required when running multiple copies of PA at the same time to avoid data loss.
