As per our policy, the following features have been deprecated in the 4.X series and are now
removed:
* ``Request.getfuncargvalue``: use ``Request.getfixturevalue`` instead.
* ``pytest.raises`` and ``pytest.warns`` no longer support strings as the second argument.
* ``message`` parameter of ``pytest.raises``.
* ``pytest.raises``, ``pytest.warns`` and ``ParameterSet.param`` now use native keyword-only
syntax. This might change the exception message from previous versions, but they still raise
``TypeError`` on unknown keyword arguments as before.
* ``pytest.config`` global variable.
* ``tmpdir_factory.ensuretemp`` method.
* ``pytest_logwarning`` hook.
* ``RemovedInPytest4Warning`` warning type.
* ``request`` is now a reserved name for fixtures.
For more information consult
`Deprecations and Removals <https://docs.pytest.org/en/latest/deprecations.html>`__ in the docs.

The ``--result-log`` option produces a stream of test reports which can be

tools would provide a suitable and better alternative.
The current plan is to provide an alternative in the pytest 5.0 series and remove the ``--result-log``
option in pytest 6.0 after the new implementation proves satisfactory to all users and is deemed
stable.
The actual alternative is still being discussed in issue `#4488 <https://github.com/pytest-dev/pytest/issues/4488>`__.
