Selenium WebDriver - Logging

Selenium Webdriver can be used for logging information during test execution. The logging is mainly used to extract information about how the execution took place.

The first step towards logging comes with enabling logging with default settings with respect to each class. Let us first enable the default logging, which is applicable to all loggers using the root logger.

Logger logger = Logger.getLogger("");

Since logging is set with respect to a class, we can set the logging level applicable to a class.

((RemoteWebDriver) driver).setLogLevel(Level.INFO);
Logger.getLogger(SeleniumManager.class.getName())
.setLevel(Level.SEVERE);

There are a total seven log levels - SEVERE, WARNING, INFO, CONFIG, FINE, FINER, and FINEST. The INFO log level is the default one which means there are no action items to be taken care of in our code and purely used for informational purposes.

Logger logger = Logger.getLogger("");
logger.setLevel(Level.INFO);

Always, all logging levels are not required, so we can filter out the logs based on the levels using the setLevel() method.

Logger logger = Logger.getLogger("");
logger.setLevel(Level.WARNING);

In the above example, log level of WARNING has been set, meaning that some actions need to be taken care, specifically for using deprecated versions in our code.

Example

Code Implementation with WARNING log levels.

package org.example;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.remote.RemoteWebDriver;
import java.util.concurrent.TimeUnit;
import java.util.logging.Level;

public class LoggingLvl {
   public static void main(String[] args) throws InterruptedException {

      // Initiate the Webdriver
      WebDriver driver = new ChromeDriver();

      // enabling log levels to Warning
      ((RemoteWebDriver) driver).setLogLevel(Level.WARNING);

      //adding implicit wait of 12 secs
      driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS);

      // Opening the webpage
      driver.get("https://www.tutorialspoint.com/selenium/practice/selenium_automation_practice.php");

      // getting current URL
      System.out.println("Getting the Current URL: " + driver.getCurrentUrl());

      // quitting the browser
      driver.quit();
   }
}

Output

In the above example, we have obtained the WARNING log levels along with the browser title with the message as Getting the Current URL: https://www.tutorialspoint.com/selenium/.

The logging information also contains debug information for looking into a specific issue and correcting it. This can be done by setting the log level to FINE.

Logger logger = Logger.getLogger("");
logger.setLevel(Level.FINE);

Let us take another example, where we would set the log level to SEVERE.

Example

Code Implementation with SEVERE log levels.

package org.example;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.remote.RemoteWebDriver;
import java.util.concurrent.TimeUnit;
import java.util.logging.Level;

public class LoggingLvls {
   public static void main(String[] args) throws InterruptedException {

      // Initiate the Webdriver
      WebDriver driver = new ChromeDriver();

      // enabling log levels to SEVERE
      ((RemoteWebDriver) driver).setLogLevel(Level.SEVERE);

      //adding implicit wait of 12 secs
      driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS);

      // Opening the webpage
      driver.get("https://www.tutorialspoint.com/selenium/practice/selenium_automation_practice.php");

      // Identify the input box with xpath locator
      WebElement e = driver.findElement(By.xpath("//*[@id='name']"));

      // enter text in input box
      e.sendKeys("Selenium");

      // getting current URL
      System.out.println("Getting the Current URL: " + driver.getCurrentUrl());

      //quitting the browser
      driver.quit();
   }
}

In the above example, we have obtained the SEVERE log levels along with the browser title with the message as Getting the Current URL: https://www.tutorialspoint.com/selenium/.

The logs generated in the console can be written to another file by using a handler. All the logs are placed in System.err by default.

Syntax

// enabling log levels to WARNING
Logger logger = Logger.getLogger("");
logger.setLevel(Level.WARNING);

//  output logging to another file Logs.xml
Handler handler = new FileHandler("Logs1.xml");
logger.addHandler(handler);

Example

Code Implementation on LoggingLvelFile.java class file.

package org.example;

import org.openqa.selenium.WebDriver;
import java.io.IOException;
import java.util.logging.*;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.concurrent.TimeUnit;
import java.util.logging.Handler;

public class LoggingLvelFile {
   public static void main(String[] args) throws InterruptedException, IOException {

      // Initiate the Webdriver
      WebDriver driver = new ChromeDriver();

      // enabling log levels to WARNING
      Logger logger = Logger.getLogger("");
      logger.setLevel(Level.WARNING);

      //  output logging to another file Logs1.xml
      Handler handler = new FileHandler("Logs1.xml");
      logger.addHandler(handler);

      //adding implicit wait of 12 secs
      driver.manage().timeouts().implicitlyWait(12, TimeUnit.SECONDS);

      // Opening the webpage
      driver.get("https://www.tutorialspoint.com/selenium/practice/selenium_automation_practice.php");

      // getting current URL
      System.out.println("Getting the Current URL: " + driver.getCurrentUrl());

      //quitting the browser
      driver.quit();
   }
}

Output

Getting the Current URL: 
https://www.tutorialspoint.com/selenium/practice/selenium_automation_practice.php

Process finished with exit code 0

In the above example, we retrieved the browser title with the message in the console - Getting the Current URL:

https://www.tutorialspoint.com/selenium/.

Finally, the message Process finished with exit code 0 was received, signifying successful execution of the code.
