Changelog

1.19.0

================================

Deprecations and Removals

• --boxed functionality has been moved to a separate plugin, pytest-forked <https://github.com/pytest-dev/pytest-forked>. This release now depends on
  pytest-forked and provides --boxed as a backward compatibility
  option. (1 <https://github.com/pytest-dev/pytest-xdist/issues/1>)

Features

• New --dist=loadscope option: sends group of related tests to the same
  worker. Tests are grouped by module for test functions and by class for test
  methods. See README.rst for more information. (191 <https://github.com /pytest-dev/pytest-xdist/issues/191>_)

• Warnings are now properly transferred from workers to the master node. (92 <https://github.com/pytest-dev/pytest-xdist/issues/92>_)

Bug Fixes

• Fix serialization of native tracebacks (--tb=native). (196 <https://github.com/pytest-dev/pytest-xdist/issues/196>_)

1.18.2

================================

Bug Fixes

• Removal of unnecessary dependency on incorrect version of py. (105 <https://github.com/pytest-dev/pytest-xdist/issues/105>_)

• Fix bug in internal event-loop error handler in the master node. This bug
  would shadow the original errors making extremely hard/impossible for users
  to diagnose the problem properly. (175 <https://github.com/pytest- dev/pytest-xdist/issues/175>_)

1.18.1

================================

Bug Fixes

• Fixed serialization of longrepr.sections during error reporting from
  workers. (171 <https://github.com/pytest-dev/pytest-xdist/issues/171>_)

• Fix ReprLocal not being unserialized breaking --showlocals usages. (176 <https://github.com/pytest-dev/pytest-xdist/issues/176>_)

1.18.0

================================

• pytest-xdist now requires pytest>=3.0.0.

Features

• Add long option --numprocesses as alternative for -n. (168)

Bug Fixes

• Fix serialization and deserialization dropping longrepr details. (133)

1.17.1

================================

Bug Fixes

• Hot fix release reverting the change introduced by 124, unfortunately it
  broke a number of test suites so we are reversing this change while we
  investigate the problem. (157)

Improved Documentation

• Introduced towncrier for CHANGELOG management. (154)

• Added HOWTORELEASE documentation. (155)

1.17.0

---

• fix 124: xdist would mark test as complete after 'call' step. As a result,
  xdist could identify the wrong test as failing when test crashes at teardown.
  To address this issue, xdist now marks test as complete at teardown.

1.16.0

---

• pytest-xdist now requires pytest 2.7 or later.

• Add worker_id attribute in the TestReport

• new hook: pytest_xdist_make_scheduler(config, log), can return custom tests items
  distribution logic implementation. You can take a look at built-in LoadScheduling
  and EachScheduling implementations. Note that required scheduler class public
  API may change in next pytest-xdist versions.
