fiona/rasterio - failing tests when building package - not after installation

[Johan Van de Wauw <johan.vandewauw@gmail.com>]

Hi all,

When updating fiona [1]. I noticed some tests fail while building the
package. The same test do not fail however if I run them manually
after installation.

All tests which fail are using CliRunner from the click package:
from click.testing import CliRunner

I wonder if anyone has suggestions on how to run these tests anyway. I
was actually thinking to have the tests while building, but to add the
tests to debian CI [2], but maybe someone knows a way to make these
tests work.

Note that exactly the same problem affects rasterio.

Kind Regards,
Johan
