如何设置木偶驱动程序的详细程度？

Question

无法管理木偶司机的冗长！！

环境：

Gecko driver 0.17.0
Selenium java 3.5.3
Firefox 52.3

试过了：

FirefoxOptions options = new FirefoxOptions();
options.addPreference("log", "{level: info}");
DesiredCapabilities ffCapabilities = DesiredCapabilities.firefox();
ffCapabilities.setCapability("moz:firefoxOptions", options);
ffCapabilities.setCapability("marionette", true);                                         
driver = new FirefoxDriver(ffCapabilities);

日志信息：

Answer 1

在 Mozilla Firefox 的发布版本中，geckodriver 的默认日志级别设置为 INFO 级别。也许您的框架或您正在使用的语言绑定 (Java) 覆盖了默认设置。

我们可以将日志级别设置为以下任一级别：

• All
• CONFIG
• FINE
• FINER
• FINEST
• INFO
• OFF
• SEVERE
• WARNING

这是将日志级别设置为OFF的代码块：

package demo;

import java.util.logging.Level;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;

public class Gecko_TRACE_LOGS 
{
    public static void main(String[] args) 
    {
        System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
        FirefoxOptions options = new FirefoxOptions();
        options.setLogLevel(Level.OFF);
        WebDriver driver =  new FirefoxDriver(options);
        driver.get("https://stackoverflow.com");
        System.out.println("Application opened");
        System.out.println("Page Title is : "+driver.getTitle());
        driver.quit();
    }
}
