标签: java selenium selenium-webdriver

我正在尝试设置一个简单的Selenium项目,但我无法正确设置初始设置。我目前的代码是:

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;

public class webdriverdemo {

    public static void main(String[] args) {

        System.setProperty("webdriver.gecko.driver", "geckodriver");
        FirefoxOptions firefoxOptions = new FirefoxOptions();
        firefoxOptions.setCapability("marionette", true);
        WebDriver driver = new FirefoxDriver(firefoxOptions);
        driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);

        driver.navigate().to("http://www.calculator.net/");

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

        driver.findElement(By.xpath(".//*[@id = 'menu']/div[3]/a")).click();

        driver.findElement(By.xpath(".//*[@id = 'menu']/div[4]/div[3]/a")).click();

        driver.findElement(By.id("cpar1")).sendKeys("10");

        driver.findElement(By.id("cpar2")).sendKeys("50");

        driver.findElement(By.xpath(".//*[@id = 'content']/table/tbody/tr[2]/td/input[2]")).click();

        String result = driver.findElement(By.xpath(".//*[@id = 'content']/p[2]/font/b")).getText();

        System.out.println("The result is " + result);

        driver.close();

    }

}

我得到的错误是:

我尝试了很多东西,但我对这些东西很陌生,所以我真的无法解决它。我该怎么做才能解决这个问题?我也尝试过使用RemoteWebDriver,但这也没有用。我没有用铬等测试过。

我正在使用OpenSUSE Linux和Firefox 52.4

1 个答案:

答案 0 :(得分:0)

您需要在此处进行一些更改:

  1. 我们需要具体为 import org.openqa.selenium.*;
  2. ,而不是 import org.openqa.selenium.WebDriver;
  3. 您需要提供 geckodriver 的绝对路径,如下所示:

    System.setProperty("webdriver.gecko.driver", "/usr/bin/geckodriver");
    
  4.   

    确保在 geckodriver 目录中复制 /usr/bin/ 二进制文件并进行必要的访问。
