AttributeError: 'ElementTree' object has no attribute 'getiterator' when using --cocotbxml=... with Python 3.9.1

With Python 3.9.1 I get the following error without

Traceback (most recent call last):
  ...
  File ".../cocotb_test/plugin.py", line 40, in pytest_sessionfinish
    for testsuite in tree.getiterator("testsuite"):
AttributeError: 'ElementTree' object has no attribute 'getiterator'

Based on the following bugfix:

• What’s New In Python 3.9
  Methods getchildren() and getiterator() of classes ElementTree and Element in the ElementTree module have been removed. They were deprecated in Python 3.2. Use iter(x) or list(x) instead of x.getchildren() and x.iter() or list(x.iter()) instead of x.getiterator(). (Contributed by Serhiy Storchaka in bpo-36543.)
  • bpo-36543 Removed methods Element.getchildren(), Element.getiterator() and ElementTree.getiterator() and the xml.etree.cElementTree module.

Element.getiterator() should be replaced with .iter(x). Changing these two lines in cocotb_test/plugin.py:

40:                for testsuite in tree.getiterator("testsuite"):
...
44:                     for testcase in testsuite.getiterator("testcase"):

to:

40:                for testsuite in tree.iter("testsuite"):
...
44:                     for testcase in testsuite.iter("testcase"):

fixes the issue.

This is already there:

cocotb-test/cocotb_test/plugin.py

Lines 40 to 43 in 9bd8e5a

	for testsuite in tree.iter("testsuite"):
	use_element = None
	for testcase in testsuite.iter("testcase"):

I can make the last release for cocotb 1.4

I am closing this but feel free to reopen if needed.

[amal-khailtash]

Yes, you are right, I think I encountered this with coco-tb 1.4. Thanks.

[amal-khailtash]

I get this message though when I try to install cocotb-test. Is cocotb-test compatible with cocotb>=1.4? You seem to have a hard requirement on cocotb==1.4.

cocotb-test 0.1.2.dev0 requires cocotb==1.4.*, but you have cocotb 1.5.0rc2 which is incompatible.

And cocotb-bus 0.1.1 seems to requires cocotb<2.0,>=1.5.0.dev, so it only gets cocotb=1.4.0 and not cocotb=1.5.0rc2. Is it possible to relax cocotb-test requirement to be cocotb>=1.4?

[themperek]

Unfortunately, there are some incompatibilities so I did this to avoid issues.
This need to get in #128 for 1.5 support.

All this will get cleaned next week when cocotb 1.5 is released. Sorry for the inconvinicen.
I will also release new versions to the cocotb-test next week.

[amal-khailtash]

That is alright, thanks for the info and this package. 😄

[amal-khailtash]

I confirm that the latest master branch works with cocotb 1.5 and modified pytest-parallel. Waiting for a new release of cocotb-test that depends on cocotb==1.5.0
