org.openqa.selenium.SessionNotCreatedException:未创建会话已断开连接:无法使用ChromeDriver和Chrome将消息发送到渲染器错误 [英] org.openqa.selenium.SessionNotCreatedException: session not created disconnected:unable to send message to renderer error with ChromeDriver and Chrome

问题描述

我尝试使用Selenium在Java上运行此简单程序:

I try to run this simple program on Java with Selenium:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;


public class MySelenium {

    public static void main(String[] args) {
        System.out.println("First Selenium");
        System.setProperty("webdriver.chrome.driver", "C:\\automation\\drivers\\chromedriver.exe");
        WebDriver driver = new ChromeDriver();
        driver.get("https://www.seleniumhq.org/");
        driver.quit();              
    }
}

但是在运行时显示以下错误:

But on running shows the following error:

如何解决此错误?

推荐答案

此错误消息...

org.openqa.selenium.SessionNotCreatedException: session not created 
disconnected: unable to send message to renderer

...表示 ChromeDriver 无法启动/产生新的 WebBrowser ，即 Chrome浏览器会话.

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

我怀疑您的主要问题是所使用的二进制文件版本之间的不兼容性.

I suspect your main issue is the incompatibility between the version of the binaries you are using.

根据快照，您提供了以下正在使用的二进制文件集:

As per the snapshot you have provided the following set of binaries you are using looks fine to me:

• JDK : 1.8.0_191
• 硒: 3.14.0
• ChromeDriver : 2.43
• Chrome : 69.0

• JDK: 1.8.0_191
• Selenium: 3.14.0
• ChromeDriver: 2.43
• Chrome: 69.0

• 根据使用以下命令无法接收来自渲染器错误的消息chrome驱动程序2.27 的另一个潜在原因可能是 localhost 中存在防病毒，您需要禁用.

• As per Unable to receive message from renderer error using chrome driver 2.27 another pottential reason can be presence of antivirus within your localhost which you need to disable.

确保系统上的/etc/hosts 包含以下条目:

Ensure that /etc/hosts on your system contains the following entry:

127.0.0.1 localhost.localdomain localhost
#or
127.0.0.1 localhost loopback

将 Chrome 版本保持在 Chrome v68-70 级别之间. (根据ChromeDriver v2.43发行说明)

Keep Chrome version between Chrome v68-70 levels. (as per ChromeDriver v2.43 release notes)

您可以在自动化测试错误:org中找到相关的讨论. openqa.selenium.WebDriverException:断开连接:无法连接到渲染器

根据

As per ChromeDriver 2.34 doesn't wait until iframe content loads after switching into iframe this issue was also observed with ChromeDriver 2.38 and Chrome 67+ combo and was related to static iframes (part of the originally loaded DOM) which seem to work correctly even till Chrome 66.
