Why so many test messages?

Hi,

I’m writing a cocotb test that will loop through a list of test functions and call them. The test looks like this:

@cocotb.test()
async def test_08_factory_tests(dut):
    """Tests different aspects of the factory"""
    tc08 = t08.s08_factory_classes_TestCase()
    methods = inspect.getmembers(t08.s08_factory_classes_TestCase)#, predicate=inspect.ismethod)
    for mm in methods:
        (name,function) = mm
        if name.startswith("test_"):
            test = getattr(tc08, name)
            tc08.setUp()
            print(f"**** Running: {name}")
            test()
            tc08.tearDown()

The functions run if they start with “test_”

    def test_no_assert(self):
        pass

    def test_no_assert2(self):
        pass

Strangely, when I run this all the messages from cocotb get repeated once per function, even though they are all in one test:

**** Running: test_no_assert
**** Running: test_no_assert2
  1000.00ns INFO     cocotb.regression                         regression.py:364  in _score_test                     Test Passed: test_08_factory_tests
INFO: regression.py(364)[cocotb.regression]: Test Passed: test_08_factory_tests
INFO: regression.py(364)[cocotb.regression]: Test Passed: test_08_factory_tests
  1000.00ns INFO     cocotb.regression                         regression.py:487  in _log_test_summary               Passed 1 tests (0 skipped)
INFO: regression.py(487)[cocotb.regression]: Passed 1 tests (0 skipped)
INFO: regression.py(487)[cocotb.regression]: Passed 1 tests (0 skipped)

And then later

INFO: regression.py(557)[cocotb.regression]: **********************************************************************************************
** TEST                                  PASS/FAIL  SIM TIME(NS)  REAL TIME(S)  RATIO(NS/S) **

**********************************************************************************************

INFO: regression.py(557)[cocotb.regression]: **********************************************************************************************

This is filling up my log with a lot of garbage. Any idea why this is happening?

That is, I would recommend doing at the top of your file:

uvm_root_logger = logging.getLogger('uvm')

and then inside your __init__, replacing

-self.logger = logging.getLogger(full_name) 
+self.logger = uvm_root_logger.getChild(full_name)

If you attach the handlers to uvm_root_logger, then you also don’t need to copy them to every logger.

Done. Thanks again!
