Generate Log Python

Question

I am new to coding and I did not understand why I cannot generate logs after my test case is done.

Here is the code for generating log



class LogGen:
    @staticmethod
    def loggen():
        logging.basicConfig(filename=".\\Logs\\automation.log",
                            format='%(asctime)s: %(levelname)s: %(message)s', datefmt='%m/%d/%Y %I:%M:%S %p')
        logger = logging.getLogger()
        logger.setLevel(logging.INFO)
        return logger

And here is the code where I call this method:

from selenium import webdriver
from pageObjects.storetest import store_test
from utilities.readProperties import ReadConfig
from selenium.webdriver.common.keys import Keys
import time
from utilities.customeLogger import LogGen


class Test_001_learning:
    baseURL = ReadConfig.getApplicationURL()
    email = ReadConfig.getUseremail()
    password = ReadConfig.getPassword()
    logger = LogGen.loggen()
    PURCHASEPRICE = "100"
    DOWNPAYMENT = "10"
    HOMEINSURANCE = "10"
    PROPERTYTAXES = "10"
    HOADUES = "10"

    def test_store(self, setup):
        self.logger.info("********* Test_001_Learning ********")
        self.logger.info("********* LOggin test  ********")
        self.driver = setup
        self.driver.get(self.baseURL)
        self.driver.get(self.baseURL)
        self.lp = store_test(self.driver)
        self.lp.setemail(self.email)
        self.lp.setpassword(self.password)
        self.lp.button1()
        title = self.driver.title
        if title == "Dashboard / nopCommerce administration":
            assert True
            self.logger.info("********* Test Pass ********")
        else:
            self.driver.save_screenshot(".\\Screenshots\\" + "test_calculator2.png")
            assert False

        self.lp.button2()
        self.driver.close()

But after the test case is done no logs are generated.

Thank you in advanced!

How are you calling the tests? I mean the command for running the tests. — Shagun Sodhani, Jan 14 '21 at 12:15
In the video from youtube is working and is the same code but he got the 3.6 python version and I got 3.9 — iollo, Jan 14 '21 at 12:18
On this page it is described how to create a logger that you can use in multiple classes https://docs.python.org/3/howto/logging-cookbook.html — Bongni, Jan 14 '21 at 12:24

By default, pytest overwrites any custom logging configuration with its own one in order to capture any logs emitted in the test run; this is useful to test whether your application emits the logs correctly. You can disable this functionality by turning off the logging plugin:

$ pytest -p no:logging ...

Now no logs will be captured and your own logging configuration is applied.

Alternative: live logs

However, pytest also has a neat feature of live logging; when enabled, it will capture the logs and write them to terminal or file or both. You can thus replace LogGen with the configuration done in pytest.ini or pyproject.toml. Example with pyproject.toml:

[tool.pytest.ini_options]
log_file = "Logs/automation.log"
log_file_level = "INFO"
log_file_format = "%(asctime)s: %(levelname)s: %(message)s"
log_file_date_format = "%m/%d/%Y %I:%M:%S %p"

In the tests, just use the root logger; no need to configure anything in code:

class Test_001_learning:

    def test_store(self):
        self.logger = logging.getLogger()
        self.logger.info("********* Test_001_Learning ********")
        ...

Shameless self-promotion: check out my other answer for more configuration examples.

If I use pytest -p no:logging all my test cases are starting running – iollo Jan 14 '21 at 15:04

The ellipsis in the command indicates the spot where you place additional arguments, e.g. `pytest -p no:logging -v -s testCases/test1learning.py` – hoefling Jan 14 '21 at 15:09
Oki doki, thank you! And sorry but I am still learning – iollo Jan 14 '21 at 15:15
Now I got this error messages: http://joxi.ru/J2bgz3luV7qGwA?d=1 – iollo Jan 14 '21 at 15:16
Probably windows; try wrapping in quotes: `-p "no:logging"` – hoefling Jan 14 '21 at 15:27
Wait, what exactly are you doing? You should invoke the command from the terminal; it looks like you have pasted it in the code instead. – hoefling Jan 14 '21 at 15:54
In the terminal I do the command http://joxi.ru/vAWz8yZTOPRZ92?d=1 – iollo Jan 14 '21 at 19:51

Check what the error tells you - you have pasted the command in the Python code at `customeLogger.py`. Your code is thus not runnable until you fix the code. – hoefling Jan 14 '21 at 20:42
Thank you very much! that was – iollo Jan 14 '21 at 21:01
