在黄瓜picocontainer中获取空指针异常

时间:2018-08-24 07:15:56

标签: maven selenium cucumber picocontainer

我正在尝试使用picocontainer将webdriver传递到步骤定义中,但得到空指针

请在下面将我的实用程序类引用声明为public的webdriver实例:-

package base;
import org.openqa.selenium.WebDriver;

public class Utils {
  public WebDriver driver;
}

请在下面参考我的实用程序类,该类具有用于调用和销毁驱动程序实例的钩子:-

    public class Baseutils extends Utils {

    private Utils obj;

    public Baseutils(Utils obj) {
        this.obj=obj;
    }

    @Before("@chrome")
    public void chromeSetup()
    {
        if(obj.driver==null)
        {
            System.out.println("Chrome instance has been instantiated");
            System.setProperty("webdriver.chrome.driver", 
                  PropertiesfileReader.getchromepath());
            ChromeOptions options=new ChromeOptions();
            options.addArguments("--start-maximized");
            options.addArguments("--disable-notifications");
            options.addArguments("--no-proxy-server");
            obj.driver=new ChromeDriver(options);
        }
    }

    @Before("@firefox")
    public void firefoxSetup()
    {
        if(obj.driver==null)
        {
            System.out.println("Firefox instance has been instantiated");
            System.setProperty("webdriver.gecko.driver",PropertiesfileReader.getgeckopath());
            obj.driver=new FirefoxDriver();
            obj.driver.manage().window().maximize();
        }
    }

    @After
    public void teardown()
    {
        if(obj.driver!=null)
        {
            System.out.println("Browser instance has been closed");
            obj.driver.close();

        }
    }
}

我的功能文件描述如下:-

Feature: To verify and validate login functionality of Orangehrmdemo website

Background:
Given User navigates to Orangehrm demo

@chrome
Scenario: To verify login for valid user credentials

 When Homepage of website is displayed
 Then User validates login page contents
 Then User enters "Admin" and "admin123" and click on login button

与功能文件相对应的步骤定义文件如下:-

 public class orangehrmdemoSteps extends Utils {

 private Utils obj;

public orangehrmdemoSteps(Utils obj) {
    this.obj = obj;
 }

WebElement username= obj.driver.findElement(By.id("txtUsername"));
WebElement password=obj.driver.findElement(By.id("txtPassword"));
WebElement loginbutton=obj.driver.findElement(By.id("btnLogin"));

@Given("^User navigates to Orangehrm demo$")
public void user_navigates_to_Orangehrm_demo()  {
    obj.driver.get(PropertiesfileReader.geturltwo());
    obj.driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
}

@When("^Homepage of website is displayed$")
public void homepage_of_website_is_displayed()  {
    WebElement logo=obj.driver.findElement(By.cssSelector("div#divLogo img"));
    Assert.assertTrue("Logo on orange hrm is not displayed", logo.isDisplayed());
}

@Then("^User validates login page contents$")
public void user_validates_login_page_contents() {
  Assert.assertTrue("username field not displayed", username.isDisplayed());
  Assert.assertTrue("password field not displayed", password.isDisplayed());
  Assert.assertTrue("login button not displayed", loginbutton.isDisplayed());
}

@Then("^User enters \"([^\"]*)\" and \"([^\"]*)\" and click on login button$")
public void user_enters_and_and_click_on_login_button(String uname, String pwd)  {
   username.sendKeys(uname);
   password.sendKeys(pwd);
   loginbutton.submit();
  }
}

我的跑步者文件如下:-

@RunWith(Cucumber.class)
@CucumberOptions(strict = true,plugin = 
{"pretty","html:target/html/automation"},features = 
{"src/test/java/featurefiles"},glue ={"stepDefinitions"},tags = "@chrome")

public class one { }

    at ✽.Given User navigates to Orangehrm demo(orangehrmDemo.feature:4)


    Process finished with exit code -1

给出错误的行号是因为驱动程序在下面突出显示的行为空:-

    public class orangehrmdemoSteps extends Utils {

   private Utils obj;

    public orangehrmdemoSteps(Utils obj) {
        this.obj = obj;
    }

    **WebElement username= obj.driver.findElement(By.id("txtUsername"));**
    //line on which nullpointer occurs
    WebElement password=obj.driver.findElement(By.id("txtPassword"));
    WebElement loginbutton=obj.driver.findElement(By.id("btnLogin"));

答案 0 :(得分:0)

在实际的页面导航包含这些元素之前,您已尝试标识这些元素。 如您在下面所写,

WebElement username= obj.driver.findElement(By.id("txtUsername"));
WebElement password=obj.driver.findElement(By.id("txtPassword"));
WebElement loginbutton=obj.driver.findElement(By.id("btnLogin"));

@Given("^User navigates to Orangehrm demo$")
public void user_navigates_to_Orangehrm_demo()  {
    obj.driver.get(PropertiesfileReader.geturltwo());
    obj.driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

首先,您应该转到URL,然后转到相关页面,然后尝试标识WebElement,而不是在此之前。 仅将所有WebElement放在相关步骤中。

问题已解决,因为由于无法访问驱动程序实例,在步骤文件包之外的包中声明了基类。
