Providing custom cache directory name through pytest argument

[RockBomber]

Hello, All!

It is a feature request for providing custom cache directory name through pytest argument

I implemented this feature like this:

Can this feature be included in the next release?

Hi @RockBomber thanks for writing.

I think this would be better implemented as an ini option, because it seems to me it should be a configuration reused all the time. It would still be possible to change that in the command line using -o command line flag.

Can this feature be included in the next release?

Would you like to open a PR with that? It would have to go to the features branch though, given that is a new feature, and would be available in pytest-3.2.0.

Thank you for answer!
I will try to prepare PR on the weekends
