trying to add support for

.feature

files w/ pytest-bdd in 2.11.x everything works as intended when we do

file(source='test.feature')

But when doing

class GherkinSourceField(SingleSourceField):
  expected_file_extensions = (".feature",)

class GherkinSourceTarget(Target):
  alias = "gherkin_source"
  core_fields = (*COMMON_TARGET_FIELDS, GherkinSourceField,)

and changing

file

to

gherkin_source

it stops working, and the .feature file is no longer included. Feels like

file

and

gherkin_source

are functionally identical? Am I missing something?

You probably need to have that field inherit from

FileSourceField

.

that's in

main

in 2.11 it's different

There's a very lengthy discussion surrounding dependency handling. For now, I'd suggest inheriting like Tom suggests

cheers.
