Plugin configuring handlers for loggers from Python logging module.
Project description
Pytest-logger is a pytest plugin configuring handlers for loggers from Python logging module.
You can install pytest-logger via pip from PyPI:
$ [sudo] pip install pytest-logger
- Plugin puts logs on per-logger basis to:
standard output,
files within log-specific directory under pytest’s tmpdir_factory session directory.
You can setup plugin using hooks:
#conftest.py import os def pytest_logger_stdoutloggers(item): return ['foo', 'bar'] def pytest_logger_fileloggers(item): return ['foo', 'bar'] def pytest_logger_logdirlink(config): return os.path.join(os.path.dirname(__file__), 'mylogs')
have logging tests or libraries (including fixtures):
#test_something.py import pytest import logging foo = logging.getLogger('foo') foo.setLevel(logging.INFO) bar = logging.getLogger('bar') @pytest.yield_fixture(scope='session') def session_thing(): foo.info('constructing session thing') yield foo.info('destroying session thing') @pytest.yield_fixture def testcase_thing(): foo.info('constructing testcase thing') yield foo.info('destroying testcase thing') def test_one(session_thing, testcase_thing): foo.info('one executes') bar.warning('this test does nothing aside from logging') def test_two(session_thing, testcase_thing): foo.info('two executes') bar.warning('neither does this')
and expect output in terminal (if not captured):
$ py.test -s -v (...) test_something.py::test_one 00:00.001 foo: constructing session thing 00:00.001 foo: constructing testcase thing 00:00.002 foo: one executes 00:00.002 bar: this test does nothing aside from logging PASSED 00:00.002 foo: destroying testcase thing test_something.py::test_two 00:00.000 foo: constructing testcase thing 00:00.000 foo: two executes 00:00.000 bar: neither does this PASSED 00:00.000 foo: destroying testcase thing 00:00.001 foo: destroying session thing (...)
and - the same - in filesystem:
$ file mylogs mylogs: symbolic link to `/tmp/pytest-of-aurzenligl/pytest-48/logs' $ tree mylogs mylogs `-- test_something.py |-- test_one | |-- bar | `-- foo `-- test_two |-- bar `-- foo
