Null pointer exception for log4j

[reidm...@gmail.com]

Hello,

1. I added log4j dependency in maven.

2. I created log4j.properties.

3. In my BaseTest.class, I have this.

package com.diceBase;

import org.apache.log4j.BasicConfigurator;

import org.apache.log4j.Logger;

import org.apache.log4j.PropertyConfigurator;

import org.junit.BeforeClass;

import org.openqa.selenium.WebDriver;

import org.testng.ITestContext;

import org.testng.annotations.AfterMethod;

import org.testng.annotations.BeforeMethod;

import org.testng.annotations.Parameters;

　

public class BaseTest {

 

 protected WebDriver driver;

 protected Logger log;

 

 @BeforeClass

 protected void setup(ITestContext ctx){

 BasicConfigurator.configure();

 String testName = ctx.getCurrentXmlTest().getName();

 log = Logger.getLogger(testName);

 PropertyConfigurator.configure("log4j.properties");

 }

 

 

 @Parameters ({"browser"})

 @BeforeMethod

 protected void Methodstart(String browser){

 log.info("start method");

 driver = BrowsersgetDriver(browser);

 }

 

 @AfterMethod

 protected void TearDown(){

log.info("end method");

 

 try {

 Thread.sleep(5000);

 driver.quit();

 } catch (Exception e) {

 }

 }

}

When I run my xml suite file, I get error "null pointer exception" at line

log.info("start method");

Can you please advise why I get this error?

Its because of the fact that you are trying to create a logger instance based on the current <test> name

 

String testName = ctx.getCurrentXmlTest().getName();

You would need to alter this logic such that you strip out any spaces in the value of “testName” else the line log = Logger.getLogger(testName); is going to cause null to be assigned to log.

Thanks & Regards
