ostestr has no default input and causes tox to fail to work

when I run test with old way of tox, it failed I don't know why. so i ask Matthew to solve the problem. I think it needed to have a detailed document about tox Command ,or what you said add default input

We switched to use ostestr in neutron via (from tox.ini):
ostestr --regex '{posargs}'

However this means I can't pass tox parameters like I could via testr (i.e. tox -e some_env -- --until-failure test_regex).

I second the request in this bug to change ostestr so that an argument without '--' will be treated as the regex.

For example:
ostestr path.to.test

Will be treated as:
ostestr --regex path.to.test

And:
ostestr --until-failure path.to.test

Will be treated as:
ostestr --until-failure --regex path.to.test

This will allow ostestr to be used as such in tox.ini:
ostestr '{posargs}'

Which means that we'll be able (Once again) to pass parameters to ostestr via a tox invocation.

Hello, I have encountered the same problem, how to ask this question how to solve? Thank you

I am also seeing this:

Hmm, this could be the shim script is bad. I forgot they added that. Will check.
