I'm testing

[pytest].xdist_enabled = true

. I wonder if I should add pytest-xdist on

[pytest].extra_requirements

(I guess yes given it is on the default value). And also I don't see much difference. The execution seems to set

-n 1

on the pytest command line. But I have 2 cpus. Is it expected?

the final value for

-n

is set by the engine, and depends on the number of other processes Pants is concurrently running - so if you have many tests running at the same time it makes sense they might all end up with

-n 1

😢

oh, so on my 2 cpus machine, if pants runs two pytest processes, it's expected to see -

n 1

, right?

yup

Ah ok. I guess it won't change my run time then 🙂 thanks!
