Add utils for general-use functions and paths Additionally introduces a pytest_command fixture, which creates a testing environment for pytest within the tmp_path. This allows for encapsulated testing of our frameworks (i.e. snapshot, lang etc) Change-Id: Ic0a5bc4bfc0b0bfbac15bc51dd4a94fae6ee6f26

returns a preconfigured pytest command.

The following things must be passed into the parametrization:

A list of additional flags to pass to the command

Optionally a boolean flag if snapshot updates should be propagated to the inside command

i.e. if the --accept-tests flag is set, if it should also be set for the pytest command returned by this fixture
