运行黄瓜功能文件时出现以下错误 . 无法找出这里的错误 .

以下是功能文件：

功能：测试Facebook冒烟情景

Scenario: 使用有效凭据测试登录

Given 打开firefox并启动应用程序

When 我输入有效的用户名和密码

Then 用户应该能够成功登录

RUNNER CLASS下面：

package com.training.runner;

import org.junit.runner.RunWith;
import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;

@RunWith(Cucumber.class)
@CucumberOptions(features="features", glue= {"com.training.teststeps"})
public class testrunner {

}

下面的步骤定义：

package com.training.teststeps;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import cucumber.api.java.en.Given;
import cucumber.api.java.en.Then;
import cucumber.api.java.en.When;

public class testcasesteps
{
WebDriver driver;

@Given("^Open firefox and start application$")
public void openApplication() {
    driver = new FirefoxDriver();
    driver.manage().window().maximize();
    driver.get("https://www.facebook.com");
}

@When("^I enter valid username and password$")
public void enterUserDetails() {
    driver.findElement(By.id("email")).sendKeys("hello@gmail.com");
    driver.findElement(By.id("pass")).sendKeys("passwordtestpass");
}

@Then("^user should be able to login successfully$")
public void verifyApplication() {
    driver.findElement(By.id("loginbutton")).click();
}
}
