@bluetech do you know why mypy didn't catch this problem? TerminalWriter.line expects a str argument, but longrepr is declared as Any in the class definition.

a function which accepts str also accepts Any because it's gradually typed (there's options to turn this off in mypy, but getting to that ideal is very very difficult)

Ahh I indeed:

Any

A static type checker will treat every type as being compatible with Any and Any as being compatible with every type.

Thanks! My thought was that a function declaring str would accuse Any as incompatible, but the above definition clearly states otherwise. 👍

LGTM. I think CollectErrorRepr might need the same treatment, not sure.

The typing of longrepr is unfortunate...

Anyone with merge and release super powers? That changes deserves a fast track. I already opened pytest-dev/pytest-html#318 as I have a strong interest in keeping this plugin green and compatible with any new release of pytest.

Every maintainer has that. 😁

We should have a release real soon, as there are a number of regressions we should take care. 👍

Good call! It didn't require changes, but I added a test to avoid future regressions.

Indeed. We should eventually try to narrow down all possible values it might have, to eventually refactor that out somehow.
