* jedi v0.20.0 and parso v0.8.7
* test: update signature expectations for typeshed v0.20.0
- update staticmethod and format signatures to match new typeshed
- fix command line truncation test: disable autoindent instead of
relying on \<BS> after `o`, which joins lines under default
bs=eol rather than just removing the indent
The main motivation is to being able to use normal/other pytest based
tests.
Therefore this moves everything from conftest into test_integration
itself.
