Appium+Cucumber+TestNG how to make iOS real devices parallel Execute

[KuKiSiNi77]

Feature

i want to through TestNG.xml transfer parameters to make cucumber’s running class parallel Execute.i will share the code. Pls help me know what’s wrong.

Code

Debug

1. the Running Class can get the value port,udid, wdaLocalPort.but the Driver class can’t get the values
2. capabilities.setCapability(MobileCapabilityType.UDID, driver.getUdid());get a message Caused by: java.lang.NullPointerException
