Unique property name for each thread with context.ThreadIndex

Hello

It is necessary for me, during a load test, in each thread, to have a property with a unique name so that it can be accessed by a thread during the execution of a certain number of steps.

In this manual written about the context.ThreadIndex property.

I tried to use it, but when using such a script:

testRunner.testCase.setPropertyValue ("EmployeePersonId" + context.ThreadIndex, result))

I only create the EmployeePersonId0 property, and all threads use it to write their variable. And I need to create EmployeePersonId0, EmployeePersonId1, EmployeePersonId2, EmployeePersonId3 ...
And each thread used its own variable.
