java - 在selenium中打开浏览器时出现异常

Question

我已经应用了所有代码，但在 selenium 中打开 chrome 浏览器时仍然出现错误。我也为 gecko-driver 设置了属性。请检查代码并给出一些解决方案

我收到此错误

Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver. The latest version can be downloaded from http://chromedriver.storage.googleapis.com/index.html

HPS.java

package hps1;

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

public class HPS {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        WebDriver driver=new ChromeDriver();

        //System.setProperty("webdriver.chrome.driver","C:\\chromedriver.exe");
System.setProperty("webdriver.chrome.driver", "C:\\chromedriver_win32\\chromedriver.exe");
        // Open 
        driver.get("http://www.facebook.com");

        // Maximize browser
         driver.manage().window().maximize();
    }

}

您首先初始化 驱动程序，然后设置系统属性，这就是它抛出错误的原因。将属性设置行移至驱动程序初始化上方即可为您完成这项工作。

public static void main(String[] args) {
    System.setProperty("webdriver.chrome.driver", "C:\\chromedriver_win32\\chromedriver.exe");
    WebDriver driver=new ChromeDriver();

     // Open 
    driver.get("http://www.facebook.com");

    // Maximize browser

    driver.manage().window().maximize();

}
