I am creating a Global variable while execution is in progress in 1 Suite, and I am trying it to access it in next Suite that is getting executed through Testsuite-collection. But this is not happening.

The code I am trying to create Global variable is as below :  
@Keyword  
void addGlobalVariable(String name, def value) {  
GroovyShell shell1 = new GroovyShell()  
MetaClass mc = shell1.evaluate(“internal.GlobalVariable”).metaClass  
String getterName = “get” + name.capitalize()  
mc.‘static’."$getterName" = { → return value }  
mc.‘static’."$name" = value  
}

The instance of `internal.GlobalVariable` is scoped per each execution of single TestSuite.This instance is newly created and destroyed per each TestSuite run.

Therefore, even if your TestSuite1 created a property in the instance of `internal.GlobalVariable` class, it will be destroyed before TestSuite2 runs. The instance of `internal.GlobalVariable` in TestSuite2 will be newly created and will not have the property that you want to see.

If I were you, I would create a JSON file somewhere in the project as a temporary storage for values to pass around from TestSuite1 to TestSuite2. TestSuite1 writes values into the file, TestSuite2 reads values from the file. That’s all. No Groovy Metaprogramming required.
