如何解决我使用@beforesuite和@aftersuite创建单独的类时遇到Java.lang.NullPointerException错误
我正在使用Cucumber创建脚本并尝试执行功能文件。因此，我创建了一个单独的基础测试类，其中包含@beforesuite和@aftersuite批注和方法，但是当我开始执行此脚本时，出现以下 nullpointerexception 错误。

Feature: Amazon URL Validation
Scenario: Validate the URL is redirected to "https://www.amazon.in/"
Given user is on the landing page of the application
When validate the URL 'http://amzn.in' should be redirected to correct url "https://www.amazon.in/"
Then validate the page title 'Online Shopping site in India: Shop Online for Mobiles,Shoes and More - Amazon.in' message
Scenario: Navigate to create a wishlist,new release pages
When user mouse hover on accounts & list page
And click on create a wishlist link
And validate navigation is successfull
Then click on New Releases link and vaidate the page
Scenario Outline: Login amazon page and click amazon pay
When User must be login amazon page using Email as "<UserName>" and password as "<password>"
#And User enter password as "<password>"
And User must be click amazon pay link
Then Validate the page title should be 'Amazon Pay'
Examples:
|UserName |password |
|xxx@gmail.com|yyy|
步骤定义：

public void user_is_on_the_landing_page_of_the_application() throws IOException
{
//launchApplication();
System.out.println("Logged in successfully");
}
@When("validate the URL {string} should be redirected to correct url {string}")

String expectedURL=string2;
String actualURL=UtilClass.getDriver().getCurrentUrl();
//String actualURL=util.getDriver().getCurrentUrl();
System.out.println(actualURL);
assertTrue(actualURL.equalsIgnoreCase(expectedURL),"URL not found" );
}
@Then("validate the page title {string} message")
public static void validate_the_page_title_message(String string)
{
String expectedTitle= string;
System.out.println(expectedTitle);
String actualTitle=UtilClass.getDriver().getTitle();
//String actualTitle=util.getDriver().getTitle();
System.out.println(actualTitle);
assertTrue(actualTitle.equalsIgnoreCase(expectedTitle),"Page Title not found" );
}
任何人都可以帮助我，如何解决此问题。
我的意图是，在运行testng.xml文件之后，光标将指向BaseTest类并打开chrome浏览器，然后光标将指向步骤定义代码并继续该流程。
谢谢
沙爹。
