org.testng.TestNGException：無法實例類

Question

我寫了下面的代碼中使用硒驅動程序來調用谷歌瀏覽：

package automation_se; 

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

import org.testng.annotations.Test; 


public class InvokeChrome { 

    public WebDriver driver; 


public InvokeChrome() { 

     System.setProperty("webdriver.chrome.driver", "D:\\downloads\\chromedriver_win32\\chromedriver"); 
     driver = new ChromeDriver(); 
     driver.manage().window().maximize(); 

    } 

    @Test 
    public void chromeProgram() { 

    } 

} 

在運行程序作爲爲TestNG的測試，它拋出以下異常：

任何人都可以請這個例外幫助我嗎？將不勝感激。

我讀過類似的問題，但他們似乎都有程序特定的解決方案。

異常原因IllegalStateException明確規定

驅動程序可執行文件不存在：d：\下載\ chromedriver_win32 \ chromedriver

你或許應該確認路徑是否正確，並添加擴展，像這樣修改：

System.setProperty("webdriver.chrome.driver", 
    "D:\\downloads\\chromedriver_win32\\chromedriver.exe");
