Subject: [PATCH] Ensure the PYTHONPATH is set properly when testing the tutorial scripts
References: https://github.com/tiangolo/typer/pull/407
Upstream: sent

When packaging Typer for openSUSE I ran into errors because the tutorial
scripts were unable to import their colocated modules. Curiously this
only seems to be occurring when these scripts are run via coverage, as
they are in the tests. Them being run via coverage however also prevents
just changing the working directory for the script runs, as then the
coverage file would end up in the wrong directory.

Curiously, I have not been able to reproduce this issue on openSUSE Leap
but only seen it on openSUSE Tumbleweed. Thus, there might be something
weird with the Python stack or the coverage version on Tumbleweed.
However, as the same PYTHONPATH-patching is also done for the tests of
the tutorial code that run it directly and not as a subprocess, I think
it is just consistent to also do this for the script test.

For reference, this is the error that I am observing in the packaging
environment and that gets resolved by this commit:
