python logging

# Example usage:
# For now, this is how I like to set up logging in Python:

import logging

# instantiate the root (parent) logger object (this is what gets called
# to create log messages)
root_logger = logging.getLogger()
# remove the default StreamHandler which isn't formatted well
root_logger.handlers = []
# set the lowest-severity log message to be included by the root_logger (this
# doesn't need to be set for each of the handlers that are added to the
# root_logger later because handlers inherit the logging level of their parent
# if their level is left unspecified. The root logger uses WARNING by default
root_logger.setLevel(logging.INFO)

# create the file_handler, which controls log messages which will be written
# to a log file (the default write mode is append)
file_handler = logging.FileHandler('/path/to/logfile.log')
# create the console_handler (which enables log messages to be sent to stdout)
console_handler = logging.StreamHandler()

# create the formatter, which controls the format of the log messages
# I like this format which includes the following information:
# 2022-04-01 14:03:03,446 - script_name.py - function_name - Line: 461 - INFO - Log message.
formatter = logging.Formatter('%(asctime)s - %(filename)s - %(funcName)s - Line: %(lineno)d - %(levelname)s - %(message)s')
# add the formatter to the handlers so they get formatted as desired
file_handler.setFormatter(formatter)
console_handler.setFormatter(formatter)

# set the severity level of the console_hander to ERROR so that only messages
# of severity ERROR or higher are printed to the console
console_handler.setLevel(logging.ERROR)

# add the handlers to the root_logger
root_logger.addHandler(file_handler)
root_logger.addHandler(console_handler)


# given the above setup
# running this line will append the info message to the /path/to/logfile.log
# but won't print to the console
root_logger.INFO("A casual message.")
# running this line will append the error message to the /path/to/logfile.log
# and will print it to the console
root_logger.ERROR("A serious issue!")

# Logging is a means of tracking events that happen when some software runs. Logging is important for software developing, debugging and running. If you don’t have any logging record and your program crashes, there are very little chances that you detect the cause of the problem.

logging request

Logging
In many cases it can be useful to print the
response and/or request details in order to 
help you create the correct expectations and 
send the correct requests. To do help you do thi
s you can use one of the predefined filters 
supplied with REST Assured or you can use one of the shortcuts.

Request Logging

given().log().all(). .. //
Log all request specification details
including parameters, headers and body
given().log().params(). .. // Log only the parameters of the request
given().log().body(). .. // Log only the request body
given().log().headers(). .. // Log only the request headers
given().log().cookies(). .. // Log only the request cookies
given().log().method(). .. // Log only the request method
given().log().path(). .. // Log only the request path

LOGGING

import logging
LOG_FILENAME = 'example.log'
logging.basicConfig(filename=LOG_FILENAME,level=logging.DEBUG)

logging.debug('This message should go to the log file')

response logging

Response Logging
If you want to print the response body regardless of the
status code you can do:

get("/x").then().log().body() ..
This will print the response body regardless if an error occurred.
If you're only interested in printing the response body if an error
occur then you can use:

get("/x").then().log().ifError(). .. 
You can also log all details in the response
including status line, headers and cookies:

get("/x").then().log().all(). .. 
as well as only status line, headers or cookies:

get("/x").then().log().statusLine(). .. // Only log the status line
get("/x").then().log().headers(). .. // Only log the response headers
get("/x").then().log().cookies(). .. // Only log the response cookies
You can also configure to log the response
only if the status code matches some value:

get("/x").then().log().ifStatusCodeIsEqualTo(302). .. // 
Only log if the status code is equal to 302

get("/x").then().log().ifStatusCodeMatches(matcher). .. //
Only log if the status code matches the supplied Hamcrest matcher
