Selenium Logging with Log4jby seetaram on May 23, 2011

If we are executing Test Suite with hundreds of automated test cases then logging all the events might be useful.

There are two APIs available for logging events.

JUL Java Logging API

Log4j Apache Software Foundation

I am going to discuss Log4j as this is an open source logging library as well as it is very much flexible and extensible compared toJUL. Log4j is built as a subproject of Logging Services Project by the Apache Software Foundation.

Log4j is built with three main concepts: loggers, appenders, and layouts. Logger is the main engine which sends the loggingrequests to appender. Appender might be a console, a log file, printer, etc. Layout is the formatting of the log output. I think thisis sufficient for this post and for any further information on Log4j you can certainly visit Google and search for Log4j. Oninternet, you can get tons of information available for Log4j.

In the following sections configurations of Log4j and also using the logging inside a Selenium test is explained.

Download Log4j from the Apaches download link:

http:/www.apache.org/dyn/closer.cgi/logging/log4j/1.2.16/apache-log4j-1.2.16.zip

Step 1: Add the Log4j JAR file to the Java Build Path (log4j-1.2.16.jar)

Step 2: Create a new class Log4jXmlTest

Step 3: Copy the following code into the newly created class

package com.selftechy.junit4;

import com.thoughtworks.selenium.*;import org.junit.After;import org.junit.Before;import org.junit.Test;import org.apache.log4j.Logger;import org.apache.log4j.xml.DOMConfigurator;import org.apache.log4j.*;import org.apache.log4j.FileAppender;import org.apache.log4j.RollingFileAppender;

*/public class Log4jXmlTest extends SeleneseTestCase {

private static Logger Log = Logger.getLogger(Log4jXmlTest.class.getName());//

@Beforepublic void setUp() throws Exception {

DOMConfigurator.configure("log4j.xml"); Log.info("______________________________________________________________"); Log.info("Initializing Selenium...");

selenium = new DefaultSelenium("localhost", 4444, "*chrome", "http://www.google.co.in/");selenium.start();Log.info("Selenium instance started");

}

@Testpublic void testAdvancedSearch() throws Exception {

Log.info("Opening Google Website");selenium.open("http://www.google.com/");Log.info("Clicking on advanced search link");selenium.click("link=Advanced search");selenium.waitForPageToLoad("30000");Log.info("Entering search terms");selenium.type("as_q", "selenium,selftechy");Log.info("Clicking on Advanced Search button");selenium.click("//input[@value='Advanced Search']");selenium.waitForPageToLoad("30000");

}

@Afterpublic void tearDown() throws Exception {

Log.info("Stopping Selenium...");Log.info("______________________________________________________________");selenium.stop();

}

}

Step 4: Create a new XML file log4j.xml

Step 5: Copy the following code into it and save (make sure that file is saved as xml file NOT as .txt file)

Step 7: Place this log4j.xml file into Project root folder (to find out the path -> right click on the project -> click on properties. Location shows the projects root directory).


2 de 10 09/08/2012 18:11

Path to Project's root folder

Step 8: Go to Run -> Run As -> JUnit Test

Step 9: It should create a output log file in the projects root folder with name logfile.log

Step 10: Open the log file, following lines should be there in the log file.

I think this is because, you directly copied the XML for log4j configuration from the blog. There you need to makesome changes such as, first change the double quotes (i.e. you need to again key in the because the one youcopied will be in special character format). Second, change the path of the log file as required. ( sometimes after 1.0after 1.0 one ? character will be inserted when u copy from the blog that needs to be removed).

Hi,

Can you help me with storing logs in an excel file?I wanted to know how to mention the cell numbers while logging.

Thanks,Sneha

No. I dont think that you can store logs in Excel file.. having said this you can create logs in excel sheet provided you arenot using log4j but jxl or poi packages

I am not sure whether you can create logs in Excel file using log4j

Hi,

Can we insert IP address in log ? I am using selenium grid with multiple RCs . In this case I unable to know which one loggeneratd from which one RC.

Thanks,Subhash

Use the below code to get the IP address of the specific system and then insert into the specific log filesInetAddress SysIP=InetAddress.getLocalHost();

SysIP.getHostAddress()

Hi,

Im using SeleniumRC with TestNG and running my scripts through ant. My requirement is to incorporate the selenium-serverlogs in to my application logs (file set in log4j.properties).

Any help here would be very much appreciated.

Here is the code for starting selenium server in build.xml file. I added an arg line forlogging but it doesnt work.

Here is the code in log4j properties file

#Application Logslog4j.logger.devpinoyLogger=DEBUG, dest1log4j.appender.dest1=org.apache.log4j.RollingFileAppenderlog4j.appender.dest1.maxFileSize=5000KBlog4j.appender.dest1.maxBackupIndex=3log4j.appender.dest1.layout=org.apache.log4j.PatternLayoutlog4j.appender.dest1.layout.ConversionPattern=%d{dd/MM/yyyy HH:mm:ss}%c %m%nlog4j.appender.dest1.File=(path to the file)\\Application.log#do not append the old file. Create a new log file everytimelog4j.appender.dest1.Append=false

Heres the solution to your problem:

java.util.logging.Logger.getLogger(org.openqa.selenium).setLevel(Level.WARNING);

I had the same problem and couldnt find the solution on the net.In fact Selenium is using the Java Logging facility.So you just need to disable it using the corresponding API, hence the line of code above.

Cheers,

Denis
