Capturing browser logs with Selenium WebDriver using Java
提问by user3246489
Is there a way to capture browser logs while running automated test cases with Selenium? I found an article on how to capture JavaScript errors in Selenium. But that is just for Firefox and only for errors. I would like to get all the console logs.
有没有办法在使用 Selenium 运行自动化测试用例时捕获浏览器日志？我找到了一篇关于如何在 Selenium 中捕获 JavaScript 错误的文章。但这仅适用于 Firefox，并且仅适用于错误。我想获取所有控制台日志。

I assume it is something in the lines of:
我认为它是以下几行：
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();
}
}

In a more concise way, you can do:
以更简洁的方式，您可以执行以下操作：
LogEntries logs = driver.manage().logs().get("browser");
For me it worked wonderfully for catching JS errors in console. Then you can add some verification for its size. For example, if it is > 0, add some error output.
对我来说，它非常适合在控制台中捕获 JS 错误。然后您可以为其大小添加一些验证。例如，如果它 > 0，则添加一些错误输出。

A less elegant solution is taking the log 'manually' from the user data dir:
一个不太优雅的解决方案是从用户数据目录“手动”获取日志：
Set the user data dir to a fixed place:
options = new ChromeOptions(); capabilities = DesiredCapabilities.chrome(); options.addArguments("user-data-dir=/your_path/"); capabilities.setCapability(ChromeOptions.CAPABILITY, options);Get the text from the log file chrome_debug.log located in the path you've entered above.
将用户数据目录设置为固定位置：
options = new ChromeOptions(); capabilities = DesiredCapabilities.chrome(); options.addArguments("user-data-dir=/your_path/"); capabilities.setCapability(ChromeOptions.CAPABILITY, options);从位于您在上面输入的路径中的日志文件 chrome_debug.log 获取文本。
I use this method since RemoteWebDriverhad problems getting the console logs remotely. If you run your test locally that can be easy to retrieve.
我使用这种方法是因为RemoteWebDriver在远程获取控制台日志时遇到问题。如果您在本地运行测试，则可以轻松检索。

As a non-java selenium user, here is the pythonequivalent to Margus's answer:
作为非 java selenium 用户，这里是相当于 Margus 答案的python：
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
class ChromeConsoleLogging(object):
def __init__(self, ):
self.driver = None
def setUp(self, ):
desired = DesiredCapabilities.CHROME
desired ['loggingPrefs'] = { 'browser':'ALL' }
self.driver = webdriver.Chrome(desired_capabilities=desired)
def analyzeLog(self, )
data = self.driver.get_log('browser')
print(data)
def testMethod(self, ):
self.setUp()
self.driver.get("http://mypage.com")
self.analyzeLog()
Edit: Keeping Python answer in this thread because it is very similar to the Java answer and this post is returned on a Google search for the similar Python question
编辑：在此线程中保留 Python 答案，因为它与 Java 答案非常相似，并且此帖子是在 Google 搜索类似 Python 问题时返回的

Starting with Firefox 65 an about:configflag exists now so console API calls like console.log()land in the output stream and thus the log file (see (https://github.com/mozilla/geckodriver/issues/284#issuecomment-458305621).
从 Firefox 65 开始，about:config现在存在一个标志，因此控制台 API 调用像console.log()输出流中的土地一样，因此是日志文件（参见（https://github.com/mozilla/geckodriver/issues/284#issuecomment-458305621）。
profile = new FirefoxProfile();
profile.setPreference("devtools.console.stdout.content", true);

Driver manager logs can be used to get console logs from browser and it will help to identify errors appears in console.
驱动程序管理器日志可用于从浏览器获取控制台日志，这将有助于识别控制台中出现的错误。
import org.openqa.selenium.logging.LogEntries;
import org.openqa.selenium.logging.LogEntry;
public List<LogEntry> getBrowserConsoleLogs()
{
LogEntries log= driver.manage().logs().get("browser")
List<LogEntry> logs=log.getAll();
return logs;
}

Before launching webdriver, we just set this environment variable to let chrome generate it:
在启动 webdriver 之前，我们只需设置这个环境变量让 chrome 生成它：
export CHROME_LOG_FILE=$(pwd)/tests/e2e2/logs/client.log
