Generate Logs in Selenium

What are Log files?

Log files are check points that can be added at any step of code.Logs gives us detailed reasoning of any step failure .To see logs we first need to download Log4j jar file.

Steps to Configure Log4j in Selenium

1-Go to http://www.java2s.com/Code/Jar/a/Downloadapachelogginglog4jjar.htm

2-Download apache-logging/apache-logging-log4j.jar.zip( 435 k) and extract Jar File and Store it 

3-Go to Selenium>Right Click of Project Name>Click on Properties>Select Java Build Path>Go to Libraries>Add External jar and open and select the Log4j jar from the location it was saved

4- Open a notepad, Copy and Paste the code below and save the filename as Log4j.Properties with double quotes("") on it on the Project Location 

// Here we have defined root logger

log4j.rootLogger=INFO,CONSOLE,R,HTML,TTCC

// Here we define the appender

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender

log4j.appender.R=org.apache.log4j.RollingFileAppender

log4j.appender.TTCC=org.apache.log4j.RollingFileAppender

log4j.appender.HTML=org.apache.log4j.FileAppender

// Here we define log file location

log4j.appender.R.File=./log/testlog.log

log4j.appender.TTCC.File=./log/testlog1.log

log4j.appender.HTML.File=./log/application.html

// Here we define the layout and pattern

log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout

log4j.appender.CONSOLE.layout.ConversionPattern= %5p [%t] (%F:%L)- %m%n

log4j.appender.R.layout=org.apache.log4j.PatternLayout

log4j.appender.R.layout.ConversionPattern=%d - %c -%p - %m%n

log4j.appender.TTCC.layout=org.apache.log4j.TTCCLayout

log4j.appender.TTCC.layout.DateFormat=ISO8601

log4j.appender.HTML.layout=org.apache.log4j.HTMLLayout

log4j.appender.HTML.layout.Title=Application log

log4j.appender.HTML.layout.LocationInfo=true

Properties file is configured on the Project Location

The below code will generate Log info after each Steps of code execution

Notes

1-An object "L" of Logger Class has been created to generate Log Statements
2-Class name has been passed to the getLogger method because it is easy to trace the logs in case of Multiple Classes being used in a Project. See output >NotePad file a class Name is mentioned in the Log
3-Properties file of Logs has been configured in with the use of PropertyConfigurator.configure("Log4j.Properties") code

Output

Log File Created on the Project Folder
