Capturing Browser Logs with Selenium Webdriver Using Java

Capturing browser logs with Selenium WebDriver using Java

I assume it is something in the lines of:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.logging.LogEntries;
import org.openqa.selenium.logging.LogEntry;
import org.openqa.selenium.logging.LogType;
import org.openqa.selenium.logging.LoggingPreferences;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class ChromeConsoleLogging {
    private WebDriver driver;

    @BeforeMethod
    public void setUp() {
        System.setProperty("webdriver.chrome.driver", "c:\\path\\to\\chromedriver.exe");        
        DesiredCapabilities caps = DesiredCapabilities.chrome();
        LoggingPreferences logPrefs = new LoggingPreferences();
        logPrefs.enable(LogType.BROWSER, Level.ALL);
        caps.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);
        driver = new ChromeDriver(caps);
    }

    @AfterMethod
    public void tearDown() {
        driver.quit();
    }

    public void analyzeLog() {
        LogEntries logEntries = driver.manage().logs().get(LogType.BROWSER);
        for (LogEntry entry : logEntries) {
            System.out.println(new Date(entry.getTimestamp()) + " " + entry.getLevel() + " " + entry.getMessage());
            //do something useful with the data
        }
    }

    @Test
    public void testMethod() {
        driver.get("http://mypage.com");
        //do something on page
        analyzeLog();
    }
}

How can i capture Browser console log using selenium and java

public void analyzeLog() {

    LogEntries logEntries = driver.manage().logs().get(LogType.BROWSER);
    for (LogEntry entry : logEntries) {
        System.out.println(new Date(entry.getTimestamp()) + " " + entry.getLevel() + " " + entry.getMessage());
        //do something useful with the data
    }
}

How to get Chrome browser console log [INFO] entries with Selenium

thank you for your answer but unfortunately none of them worked for me, I have managed to come up with a solution for my issue using:

    ChromeOptions options = new ChromeOptions();
    options.setCapability(ChromeOptions.CAPABILITY, getCap());
    WebDriver driver = new ChromeDriver(options);

Alongside with the custom made method:

private static DesiredCapabilities getCap() {
    DesiredCapabilities caps = DesiredCapabilities.chrome();
    LoggingPreferences logPrefs = new LoggingPreferences();
    logPrefs.enable(LogType.PERFORMANCE, Level.INFO);
    logPrefs.enable(LogType.PROFILER, Level.INFO);
    logPrefs.enable(LogType.BROWSER, Level.INFO);
    logPrefs.enable(LogType.CLIENT, Level.INFO);
    logPrefs.enable(LogType.DRIVER, Level.INFO);
    logPrefs.enable(LogType.SERVER, Level.INFO);
    caps.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);
    return caps;
}

And finally had to make a filter method as the Selenium one was not working properly for me and was returning all of the entries:

private static List<LogEntry> filterLog(LogEntries entries) {
    List<LogEntry> logs = new ArrayList<>();
    for (LogEntry entry : entries) {
        if(entry.getLevel().toString().equals(INFO)) {
            logs.add(entry);
        }
    }
    return logs;
}

Selenium Web Driver: Extracted Chrome Browser logs are incomplete

Since chromedriver 75.0.3770.8 CapabilityType.LOGGING_PREFS is deprecated. Use goog:loggingPrefs instead.

Getting console.log output from Chrome with Selenium Python API bindings

Ok, finally figured it out:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

# enable browser logging
d = DesiredCapabilities.CHROME
d['loggingPrefs'] = { 'browser':'ALL' }
driver = webdriver.Chrome(desired_capabilities=d)

# load the desired webpage
driver.get('http://foo.com')

# print messages
for entry in driver.get_log('browser'):
    print(entry)

Entries whose source field equals 'console-api' correspond to console messages, and the message itself is stored in the message field.

Starting from chromedriver, 75.0.3770.8, you have to use goog:loggingPrefs instead of loggingPrefs:

d['goog:loggingPrefs'] = { 'browser':'ALL' }
