Creating PDF Report using TestNG with Selenium

There are two steps:
1. First Create JyperionListener.java

2. Then use JyperionListener.java in any TestNG class (like we have developed google.java)

1. Create class JyperionListener.java

2. Use JyperionListener.java in TestNG class, find below code of TestNG class:

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
import org.openqa.selenium.WebDriver;
import org.testng.Assert;
import org.testng.annotations.Listeners;
import org.testng.annotations.Test;

import reporting.JyperionListener;
import reusable.Base;

@Listeners(JyperionListener.class)
public class google {
 static Logger log = Logger.getLogger(NewTest.class);
 static Logger elog = Logger.getLogger("errorLog");
 WebDriver driver;
  
  @Test
  public void google1() {
    PropertyConfigurator.configure("src/main/resources/utilities/log4j.properties");
    log.info("Starting first test case");
    driver = Base.getDriver();
    driver.get("http://www.google.com/");
    Assert.assertTrue(false);
    elog.error("Test Case Fail");      
  }
}

Create HTML, Error and Execution logs using log4j -Create more than 2 log files (Core JAVA)

It will create 3 files:

1. HtmlLogReport.html
2. Logfile.log
3. ErrorLog.log

Implement the logger as per your requirement.

Below is the code for log4j.property

# Define the root logger with appender file

log4j.rootLogger = INFO, FILE, rfile
 

# Define the file appender-Logfile.log
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.logfile.File=./TestLogs/Logfile.log

# Define the layout for file appender-Logfile.log
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.File=./TestLogs/Logfile.log
log4j.appender.FILE.layout.ConversionPattern=%d [%25F:%t:%L] - %m%n

# Define the layout for RollingFileAppender-HtmlLogReport.html
log4j.appender.rfile=org.apache.log4j.RollingFileAppender
log4j.appender.rfile.File=./TestLogs/HtmlLogReport.html
log4j.appender.rfile.MaxFileSize=1000MB
log4j.appender.rfile.Append=true
log4j.appender.rfile.layout=org.apache.log4j.HTMLLayout
log4j.appender.rfile.layout.Title=HTML Log Report
log4j.appender.rfile.layout.LocationInfo=true

# For Second Log File i.e ErrorLog.log
log4j.appender.errorLog=org.apache.log4j.FileAppender
log4j.appender.errorLog.File=./TestLogs/ErrorLog.log
log4j.appender.errorLog.layout=org.apache.log4j.PatternLayout
log4j.appender.errorLog.layout.ConversionPattern=%d [%25F:%t:%L] - %m%n
log4j.logger.errorLog=TRACE,errorLog

JAVA program to implement above log4j.properties

import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
import org.openqa.selenium.WebDriver;
import org.testng.annotations.Test;
import reusable.Base;

public class google {
 static Logger log = Logger.getLogger(google.class);
 static Logger elog = Logger.getLogger("errorLog");
 WebDriver driver;
  
  @Test
  public void google1() {
    PropertyConfigurator.configure("src/main/resources/utilities/log4j.properties");
    log.info("Starting first test case");
    driver = Base.getDriver();
    driver.get("http://www.google.com/");
    elog.error("Test Case Fail");      
  }
}

Sending Email using gmail with Attachment and Text (Core JAVA)

If you want to use this function with testNG then use as below under AfterSuite annotation of TestNG:

//After complete execution send pdf report by email
    
    @AfterSuite
 
    public void tearDown(){
 
        sendPDFReportByGMail("FROM@gmail.com", "PASSWORD", "TO@zellax.com", "PDF Report", "");

Create logs in html format using log4j (Core JAVA)

There are two steps to create HTML log file:
1. Create log4j.properties
2. Create Log4jHtmlLayout.java (this is just java file specifies the usage of log4j)

If you want only customize logger then change "log4j.rootLogger = All, FILE, rfile" to "log4j.rootLogger = INFO, FILE, rfile"

log4j.properties

# Define the root logger with appender file
log4j.rootLogger = All, FILE, rfile
 

# Define the file appender
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.logfile.File=./TestLogs/Logfile.log

# Define the layout for file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.File=./TestLogs/Logfile.log
log4j.appender.FILE.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

# Define the layout for RollingFileAppender
log4j.appender.rfile=org.apache.log4j.RollingFileAppender
log4j.appender.rfile.File=./TestLogs/applog.html
log4j.appender.rfile.MaxFileSize=1000MB
log4j.appender.rfile.Append=true
