線程「main」中的異常java.lang.IllegalStateException：驅動程序可執行文件的路徑必須由webdriver.gecko.driver系統設置

Question

在發佈並給出解決方案之前，我已經厭倦了所有的事情，但仍然得到了相同的錯誤FireFox，Chrome & Internet Explorer。

import org.openqa.selenium.By; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.WebElement; 
import org.openqa.selenium.firefox.FirefoxDriver; 


public class Search { 

public static void main(String[] args) throws InterruptedException { 
    WebDriver driver = new FirefoxDriver(); 
    System.getProperty("webdriver.gecko.driver", 
      "C:\\Users\\nitin\\Downloads\\geckodriver-v0.18.0- 
    win64\\geckodriver.exe"); 
    driver.get("http://www.wikipedia.org"); 
    WebElement link; 
    link = driver.findElement(By.linkText("English")); 
    link.click(); 
    Thread.sleep(5000); 
    WebElement searchbox; 
    searchbox = driver.findElement(By.id("searchInput")); 
    searchbox.sendKeys("Software"); 
    searchbox.submit(); 
    Thread.sleep(5000); 
    driver.quit(); 

Answer 1

應該不是System.setProperty()而不是.getProperty()？

System.setProperty("webdriver.gecko.driver, "C:\\Users\\...\\geckodriver.exe");

Answer 3

使用.setProperty，並宣佈它提供的路徑後的webdriver

System.setProperty("webdriver.gecko.driver", 
      "C:\\Users\\nitin\\Downloads\\geckodriver-v0.18.0-win64\\geckodriver.exe"); 
WebDriver driver = new FirefoxDriver();
