Fix compatibility with newer versions of tox and virtualenv.
Review Request #14529 — Created July 29, 2025 and submitted — Latest diff uploaded
We were using some legacy settings and syntax for
tox
, and this
prevented newer versions from running our test suite. This change
updates the configuration to use newer setting names, to fix multi-line
lists of environment names, and to install a version ofvirtualenv
with support for older versions of Python.
Ran several test suites with a modern version of
tox
.
