I've missed this.
How do you use test_require? Do you run python setup.py test?

How do you use test_require? Do you run python setup.py test?

I do. And as long as tests_require is specified, it should be complete.

Actually, there are more missing: pytest-mock, pytest-cov trustme and brotlipy.

[webknjaz]

@dotlambda the thing is that using this mechanism is discouraged, we don't really use it and should probably just remove that completely.

[asvetlov]

@webknjaz agree
We need either use test_requires in our Travis CI or drop this facility.
I'm inclining to removal.

[webknjaz]

No, we don't use that at all. But we should probably consider it a breaking change for ones who use it so not backport. Maybe a deprecation warning though.

[dotlambda]

I don't have a problem with removing it.

[asvetlov]

Our CI is broken now.
Please keep the PR open as the reminder.
I'll close the PR after preparing a new one for dropping python setup.py test command.
