[New-bugs-announce] [issue37873] unittest: execute tests in parallel

[D. A. Pellegrino]

New submission from D. A. Pellegrino <donald.a.pellegrino at gmail.com>:

The unittest documentation makes reference to a potential parallelization feature:

"Note that shared fixtures do not play well with [potential] features like test parallelization and they break test isolation. They should be used with care." (https://docs.python.org/3/library/unittest.html)

However, it seems that executing tests in parallel is not yet a feature of unittest. This enhancement request is to add parallel execution of tests to unittest.

A command line option may be a good interface. Ideally, it would be compatible with test discovery. Outside of the Python ecosystem, a common practice is to define test cases in a Makefile and then execute GNU Make with the '-j' flag (https://www.gnu.org/software/make/manual/html_node/Parallel.html#Parallel). Adding such an option to unittest would be a convenience and may save the effort of bringing in additional libraries or tools for parallel unit test execution.
