Weird pytest error: 'CompletionHtml' object has no attribute '_text_edit' about qtconsole

I just realised that the qbot.waitUntil timeout is in a flaky report, and is fine. But it is the weird _text_edit issue which is frequently happening, even when the test_input_and_print call is successful first time.

Update: I have located the source of the issue (though I don't understand why it is breaking); it is the test in qtconsole/tests/test_inprocess_kernel.py which causes the error. Running this test under unittest rather than pytest passes with no issues.

Testing is not really my area of expertise, but the tests were set up as unittests so I'm not completely sure why you want to use pytest. In my clone of the repository, test_inprocess_kernel.py gives no error.

Hi @rayosborn, some of the test files contain only pytest tests, some contain only unittest tests and some contain a mixture. The GitHub workflow runs all the tests using pytest:

qtconsole/.github/workflows/linux-tests.yml

Lines 73 to 78 in d700870

	- name: Run tests
	shell: bash -l {0}
	run: xvfb-run --auto-servernum pytest -vv -s --full-trace --color=yes --cov=qtconsole qtconsole
	env:
	QT_API: ${{ matrix.QT_LIB }}
	PYTEST_QT_API: ${{ matrix.QT_LIB }}

But for some strange reason, this caused the error described above on a Debian system.
