在黄瓜微微容器中获取空指针异常
Getting nullpointer exception in cucumber picocontainer
我正在尝试使用 picocontainer 将 webdriver 传递到我的步骤定义中，但得到的是空指针
请参考下面我的实用程序 class 将 webdriver 实例声明为 public:-
package base;
import org.openqa.selenium.WebDriver;
public class Utils {
public WebDriver driver;
}
请参考下面我的实用程序 class 具有调用和销毁驱动程序实例的挂钩：-
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();
}
}
}
我的特征文件描述如下：-
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
特征文件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)

给出错误的行号是因为下面突出显示的行的驱动程序为空：-
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"));
您已尝试在实际导航到包含这些元素的页面之前识别这些元素。
正如您在下面所写，
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，然后是相关页面，然后尝试识别 WebElement，而不是在此之前。
仅将所有 WebElement 放在该相关步骤中。
问题现已解决，因为基类是在步骤文件包之外的包中声明的，因此无法访问驱动程序实例。
我正在尝试使用 picocontainer 将 webdriver 传递到我的步骤定义中，但得到的是空指针
请参考下面我的实用程序 class 将 webdriver 实例声明为 public:-

Process finished with exit code -1
给出错误的行号是因为下面突出显示的行的驱动程序为空：-
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"));
您已尝试在实际导航到包含这些元素的页面之前识别这些元素。 正如您在下面所写，
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，然后是相关页面，然后尝试识别 WebElement，而不是在此之前。 仅将所有 WebElement 放在该相关步骤中。
问题现已解决，因为基类是在步骤文件包之外的包中声明的，因此无法访问驱动程序实例。
