简单selenium脚本中的java错误

Question

在使用它当时执行的同一chromedriver路径之前的一天，我尝试过使用同一种脚本，但今天，当我尝试使用另一种脚本时，我得到了错误

package ScriptsSelenium;

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


public class TextBox_EntData {
    public static void main(String[] args){
        WebDriver driver = new ChromeDriver(); 
        System.setProperty("webdriver.chrome.driver","C:\\Users\\Sneha\\Downloads\\chromedriver_win32\\chromedriver.exe");
        driver.get("http://www.gmail.com");
        driver.findElement(By.id("Email")).sendKeys("XXX@YYail.com");
        driver.findElement(By.id("Passwd")).sendKeys("XXXXXX");
        driver.findElement(By.id("signIn")).click();

这是我的错误

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 http://code.google.com/p/selenium/wiki/ChromeDriver. The latest version can be downloaded from http://chromedriver.storage.googleapis.com/index.html

Answer 1

代码中唯一需要更改的是chromedriver.exepath语句的执行。在启动新的chromedriver之前，需要调用它。 换衣服

System.setProperty("webdriver.chrome.driver","C:\\Users\\Sneha\\Downloads\\chromedriver_win32\\chromedriver.exe");
WebDriver driver = new ChromeDriver(); 

Answer 2

检查一下你有没有铬驱动。exe文件，并使用以下Chrome配置

DesiredCapabilities和ChromeOptions类基本上允许您为浏览器设置一些选项（比如启动最大化浏览器、设置chromedriver路径等等）

System.setProperty("webdriver.chrome.driver", "res/chromedriver.exe");
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
ChromeOptions options = new ChromeOptions();
//this statement will not show any warnings when you launch chrome
options.addArguments("test-type");
//start a maximized window 
options.addArguments("start-maximized");
//this allows you to use a user profile
//options.addArguments("user-data-dir=D:/temp/");
capabilities.setCapability("chrome.binary","res/chromedriver.exe");
capabilities.setCapability(ChromeOptions.CAPABILITY,options);
WebDriver driver = new ChromeDriver(capabilities);
