5.2.0

pytest 5.2.0 (2019-09-28)

Deprecations

• #1682: Passing
  arguments to pytest.fixture() as positional arguments is
  deprecated - pass them as a keyword argument instead.

Features

• #1682: The
  scope parameter of @pytest.fixture can now be a callable that
  receives the fixture name and the config object as keyword-only
  parameters. See the
  docs for
  more information.

  behavior of the --pastebin option: failures to connect to the
  pastebin server are reported, without failing the pytest run

Bug Fixes

• #5806: Fix
  "lexer" being used when uploading to bpaste.net from --pastebin
  to "text".
• #5884: Fix
  --setup-only and --setup-show for custom pytest items.

Trivial/Internal Changes

• #5056: The
  HelpFormatter uses py.io.get_terminal_width for better
  width detection.
