通过硒测试运行MVN的错误

Question

我是新来的使用硒，在运行MVN验证我的测试后，我发现了一个问题。我正在使用WebDriver使用Java Junit。

这是我的测试代码：

import java.util.regex.Pattern;
import java.util.concurrent.TimeUnit;
import org.junit.*;
import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;

public class SeleniumTest {
  private WebDriver driver;
  private String baseUrl;
  private boolean acceptNextAlert = true;
  private StringBuffer verificationErrors = new StringBuffer();
  public static void main(String[] args) {
      System.setProperty("webdriver.gecko.driver", "/home/francop/Downloads/geckodriver");
      WebDriver driver = new FirefoxDriver();
      driver.get("http://localhost:8448/login");
      driver.quit();
  }
  @Before
  public void setUp() throws Exception {
      System.setProperty("webdriver.gecko.driver", "/home/francop/Downloads/geckodriver");
    driver = new FirefoxDriver();
    baseUrl = "http://localhost:8448/login";
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  }
  @Test
  public void testSelenium() throws Exception {
    driver.get(baseUrl);
    driver.findElement(By.name("username")).clear();

      String alertText = alert.getText();
      if (acceptNextAlert) {
        alert.accept();
      } else {
        alert.dismiss();
      }
      return alertText;
    } finally {
      acceptNextAlert = true;
    }
  }
}

我使用硒IDE来生成Firefox，并将其导出为Java/Junit/Web Driver。将其集成到src/test/java/中，并将必要依赖性添加到我的pom.xml

当我在终端MVN中运行时，验证它会加载测试并以失败的方式完成：

Failed tests: 
SeleniumTest.testSelenium on testSelenium(SeleniumTest)(SeleniumTest)
  Run 1: SeleniumTest.setUp:29 » IllegalAccess tried to access class org.openqa.seleniu...
  Run 2: SeleniumTest.tearDown:130 NullPointer

这是完整的错误日志：

java.lang.IllegalAccessError: tried to access class org.openqa.selenium.os.ExecutableFinder from class org.openqa.selenium.firefox.FirefoxBinary
    at org.openqa.selenium.firefox.FirefoxBinary.locateFirefoxBinariesFromPlatform(FirefoxBinary.java:412)

testSelenium on testSelenium(SeleniumTest)(SeleniumTest)  Time elapsed: 0.184 sec  <<< FAILURE!
java.lang.NullPointerException: null
    at SeleniumTest.tearDown(SeleniumTest.java:130)

还试图使用XVFB使用无防测试，但我甚至无法在本地机器中验证它。我正在使用Ubuntu 17.10

我无法为此找到任何逐步实现。或将测试集成到Jenkins Pipeline

您应该在壁虎驱动程序中添加扩展名，以解决其中一个错误。

  System.setProperty("webdriver.gecko.driver", "/home/francop/Downloads/geckodriver.exe");
  WebDriver driver = new FirefoxDriver();
