在appium中，维护服务和驱动程序的部分

如何解决在appium中，维护服务和驱动程序的部分

我在黄瓜框架上使用鸦片。 在每种情况下，我需要调用该应用程序的登录情况。如果未在每个方案之前调用登录方案，则该方案将失败并引发错误。而不是在每个方案之前每次都调用登录方案，而是如何一次调用登录方案并运行其余方案而不在每个方案之前调用登录。请在下面找到代码。运行一次登录方案，然后运行其余方案，而无需再次调用登录，功能文件中的方案仍将结束。请在一次运行登录方案并继续其他方案时找到以下错误。

错误：

   java.lang.NullPointerException
   at StepDefinations.AddCustomersSteps.user_click_on_customer_button(AddCustomersSteps.java:27)
   at ✽.user click on Customer 
   button(file:///H:/SeleniumWorkSpace/PosApp/src/test/resources/Features/AddCustomers.feature:18)

   java.lang.NullPointerException
   at StepDefinations.Hooks.getBase64Screenshot(Hooks.java:75)
   at StepDefinations.Hooks.AfterStepScreenShot(Hooks.java:65)

功能文件：

@AddCustomer
Feature: Add customer details and verify added Customer 

Background: Check login into with Valid credential and Valid Pin

Given User Launch App 
And Select the radio button for Stand Alone mode 
And Click on Done button
And user enter details
And user clicks on login
Then user navigate to the Home page
And user is on location selection page and select a location
And user enter valid pin "1234"

Scenario Outline: Verify the Adding new customer details and search the new added customer

Given user is on the app Home page
And user click on Customer button
When user enter the fields for <firstname> <lastname> <mobile> <email> <address> <landmark> <pincode> 
And User click on add customer button
Then Validate the customer added successfully <name>
Examples:
|firstname|lastname|mobile    |email           |address|landmark|pincode|name         |
|robert   |ggggg  |1234567891|[e-mail]|11-574 |tvc   |685002 |rrtyyu ttttt|


Scenario Outline: Verify the Adding Collection details

Given user is on the app Home page
And user click on Collection button
When user enter the collection details <name> <phone> <email> <note>
And user select date and time
And User click on ok button for collection
Then Validate the delivery details added for customer
Examples:
|name            |phone      |email           |note         |
|rtyuur jikrkrkrk   |1234567891 |[e-mail]|Added details|
