Yes, it seems so:

>>> from PyQt5.QtWidgets import QApplication, QWidget
>>> a = QApplication([])
>>> a.argv()

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

AttributeError: 'QApplication' object has no attribute 'argv'


Shouldn't that be QApplication.arguments()?

http://doc.qt.io/qt-5/qcoreapplication.html#arguments

There's no QApplication::argv member.

In [2]: import sys
   ...: from PyQt4 import Qt
   ...:
   ...: a = Qt.QApplication(sys.argv)
   ...:

In [3]: a.argv()
Out[3]: ['/usr/local/bin/ipython']


Now I wonder if this is a PyQt bug or something changed in Qt itself

Is there anything we can do to get the argv/argc in a python script running
inside QGIS?

This is needed by the testing environment in https://github.com/
boundlessgeo/qgis-testing-environment-docker/blob/
master/qgis_testrunner.py#L150
fortunately, there are some workarounds.
