How to find out the current running test

I am using pytest for running my test methods. And i am trying to implement a log file for each test method.

consider the following test module with test methods.

#content of test_module.py
def test_1(log):
    log.info('inside test_1')
    util.abc(log)


def test_2(log):
    log.info('inside test_2')
    util.abc(log)

The content of my util module is:

#content of util.py module
def abc(log):
    # perform some logic here and calculate result.      
    log.info('the value is: %s' % result)

And here is my conftest.py file.

#conftest.py
@pytest.fixture()
def log(request):
    test_path = request.node.parent.name.strip(".py")
    test_name = request.node.name
    node_id = request.node.nodeid
    logs_dir = pkg_resources.resource_filename("test_results", "logs")
    log_file_path = '%s/%s' % (logs_dir, test_path)
    if not os.path.exists(log_file_path):
        os.makedirs(log_file_path)
    logger_obj = logger.make_logger(test_name, log_file_path, node_id)
    yield logger_obj
    handlers = logger_obj.handlers
    for handler in handlers:
        handler.close()
        logger_obj.removeHandler(handler)

The test module test_module.py is located under tests/ directory. So, when i run the tests using py.test tests/ it executes the test_1 and test_2 methods and logs the test specific info under test_results/ directory into a log file specific to each test. test_1.log and test_2.log.

This works for me. But, the problem is that i had to pass log object from the test methods to each method that i call from the test method.

In this example when i am calling the util.abc method i am passing the log object from the test method. So, the method abc inside the util module knows which log file to log to. But, i don't want to pass in the log object this way to all the methods that i call from test methods. I believe there should be a better way. I am thinking, if there is a way to find out which test method called the method abc then i don't have to pass in the log object this way. Anyone knows on how to figure this out? or any other ideas to achieve this? Thank you!

Well, you can always create logger module. In your test methods, you will assign log to logger.log

#content of test_module.py
def test_1(log):
    logger.log = log
    log.info('inside test_1')
    util.abc()

def test_2(log):
    logger.log = log
    log.info('inside test_2')
    util.abc()

and in your normal methods just call it

def abc():
    # perform some logic here and calculate result.      
    logger.log.info('the value is: %s' % result)
