pytest-logger how to stop writing to log files but append to end of log file

i am new to pytest and also python.

I have an issue which is whenever i run the test and generate log files, it will write to the log file but not append which causes i lost the previous logs.

I am trying out the example code now.

#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')



#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')

Anyone has good solution? Thanks in advance.
