log4j in RestAssured Testing Framework

 log4j in RestAssured Testing Framework

log4j is a reliable, fast and flexible logging framework (APIs) written in Java, which is distributed under the Apache Software License.

log4j has been ported to the C, C++, C#, Perl, Python, Ruby, and Eiffel languages.

log4j is highly configurable through external configuration files at run time and it is basically used to write our own logs inside the code so it would be easy to troubleshoot code in case of any issue.

Now we need to follow the below steps to setup Log4j in rest assured testing framework.
1) In Project Folder inside pom.xml add below log4j dependencies.

2) Inside project main Folder under configuration or any other Package of choice please add below log4j.properties file with the below details.        

3) Inside project Base Class, declare one logger variable and provide the path of log4j.properties file along with the below code snapshot.

 4)  Now we are ready to use your log4j inside test classes using the below syntax.       

logger.info("Issue Created with id \t"+IssueNo);

       log4j can primarily be added on below level:

·      All - This level of logging will log everything ( it turns all the logs on )
·      DEBUG – print the debugging information and is helpful in development stage
·      INFO – the print informational message that highlights the progress of the application
·      WARN – print information regarding faulty and unexpected system behavior.
·      ERROR – the print error message that might allow the system to continue.
·      FATAL – print system critical information which is causing the application to crash

 After executing the Code output would look something like below in console.

Now after refreshing our the project, we will get one new folder created with name as log inside this folder there would be file name as testlog.log inside this file we will get all the loggers we have written inside the project.
