Log4J2 | Logging in Java framework | Selenium test automation

In this video we will discus about logging in automation framework. There are many number of logging libraries available, which can be use in our framework. But in our framework we are going to use Apache Log4j2.

Different Log events we can use in Log4j2are as below:
ERROR
WARN
INFO
DEBUG
VERBOSE

dependency
artifactId log4j-core /artifactId
version 2.13.3 /version
/dependency

To initialize the logger in class you can write the below code.

Then you can use the log object to generate logs.

Based on the minimum log event type, provided in the configuration we will get the log events in the log file.

#?xml version="1.0" encoding="UTF-8"?#
#Configuration status="WARN" strict="true"#
#Properties#
#/Properties#
#Appenders#
#Appender type="Console" name="STDOUT" #
#Layout type="PatternLayout" pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/#

#/Appender#
#Appender type="File" name="File" fileName="${filename}"#
#Layout type="PatternLayout" pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/#

#/Appender#
#/Appenders#

#Loggers#

#AppenderRef ref="File"/#
