为来自python日志模块的日志记录器配置处理程序的插件。
pytest-logger的Python项目详细描述
pytest logger是一个pytest插件，为python日志模块中的日志记录器配置处理程序。
您可以通过pip从PyPI：
安装pytest记录器$ [sudo] pip install pytest-logger
插件根据每个记录器将日志放到：
- 标准输出，
- pytest的tmpdir_factorysession目录下的日志特定目录中的文件。
您可以使用钩子设置插件：
#conftest.py
import os
def pytest_logger_config(logger_config):
logger_config.add_loggers(['foo', 'bar', 'baz'], stdout_level='info')
logger_config.set_log_option_default('foo,bar')
def pytest_logger_logdirlink(config):
return os.path.join(os.path.dirname(__file__), 'mylogs')
进行日志记录测试或库（包括设备）：
#test_something.py
import pytest
import logging
foo = logging.getLogger('foo')
bar = logging.getLogger('bar')
baz = logging.getLogger('baz')
@pytest.yield_fixture(scope='session')
def session_thing():
foo.debug('constructing session thing')
yield
foo.debug('destroying session thing')
@pytest.yield_fixture
def testcase_thing():
foo.debug('constructing testcase thing')
yield
foo.debug('destroying testcase thing')
def test_one(session_thing, testcase_thing):
foo.info('one executes')
bar.warning('this test does nothing aside from logging')
baz.info('extra log, rarely read')
def test_two(session_thing, testcase_thing):
foo.info('two executes')
bar.warning('neither does this')
baz.info('extra log, not enabled by default')
并期望终端输出（如果未捕获）：
$ py.test -s -v (...) test_something.py::test_one 00:00.002 inf foo: one executes 00:00.002 wrn bar: this test does nothing aside from logging PASSED test_something.py::test_two 00:00.000 inf foo: two executes 00:00.000 wrn bar: neither does this PASSED
能够通过命令行选项更改此输出：
$ pytest -s -v --log foo.debug,baz (...) test_something.py::test_one 00:00.002 dbg foo: constructing session thing 00:00.002 dbg foo: constructing testcase thing 00:00.002 inf foo: one executes 00:00.003 inf baz: extra log, rarely read PASSED test_something.py::test_two 00:00.000 dbg foo: constructing testcase thing 00:00.000 inf foo: two executes 00:00.001 inf baz: extra log, not enabled by default PASSED
和-相同-在文件系统中：
$ file mylogs
mylogs: symbolic link to `/tmp/pytest-of-aurzenligl/pytest-48/logs'
$ tree mylogs
mylogs
`-- test_something.py
|-- test_one
| |-- bar
| |-- baz
| `-- foo
`-- test_two
|-- bar
|-- baz
`-- foo
