test.{support, regrtest} are the internal packages cpython
developers use to write tests.
Although they are not public and the API may change/break
some developers use these packages to write tests for their
(3rd party) software.
The derivations for cpython now only remove the actual tests
but leave the packages in place that are used to write them.

|
|
Python is a remarkably powerful dynamic programming language that
|
|
is used in a wide variety of application domains. Some of its key
|
|
distinguishing features include: clear, readable syntax; strong
|
|
introspection capabilities; intuitive object orientation; natural
|
|
expression of procedural code; full modularity, supporting
|
|
hierarchical packages; exception-based error handling; and very
|
|
high level dynamic data types.
