[tuvshinot]

i think it looks same as #464.

[tuvshinot]

when i run single test it passes, but when run multiple it throws this.

[RonnyPfannschmidt]

indeed, please update pytest-xdist and check fi it works afterwards

[tuvshinot]

okey thanks, i will try this. and let you know )))

[cmarqu]

I had this problem with pytest-xdist 1.26.1 and can confirm that it is fixed with 1.31.0.
