# xml.etree test. This file contains enough tests to make sure that

# Large parts are extracted from the upstream test suite.

#
|
|
# PLEASE write all new tests using the standard unittest infrastructure and
|
|
# not doctest.
|
|
#
|
|
# IMPORTANT: the same tests are run from "test_xml_etree_c" in order
|

# to ensure consistency between the C implementation and the Python
|
|
# implementation.
|

|
|
# For this purpose, the module-level "ET" symbol is temporarily

# monkey-patched when running the "test_xml_etree_c" test suite.

# Don't re-import "xml.etree.ElementTree" module in the docstring,

|
# except if the test is specific to the Python implementation.
