// TestSharedSubject is based on a request posted on the CGRateS google group: https://groups.google.com/g/cgrates/c/3iqrh4CJnow.
//
// The main idea of the test is to handle a scenario where there are two groups sharing one subject:
//
// Group 1: 1001,1002,1003,1004,1005
// Group 2: 1001,1010,1011,1012,1013
//
// The goal is to handle two different pricings based on the following rules:
//   - excluding 1001, any number from Group 1 calling any number from Group 2 will use a pricing of 2 units/s.
//   - excluding 1001, any number from Group 2 calling any number from Group 1 will use a pricing of 1 unit/s.
//   - if 1001 calls a number from Group 1 or is called by a number from Group 1, a pricing of 1 unit/s will be used.
//   - if 1001 calls a number from Group 2 or is called by a number from Group 2, a pricing of 2 units/s will be used.
//
// To accomplish this, the test does the following setup:
//   - creates one rating profile with pricing for each group
//   - attaches the rating profile via changing the event subject using an attribute profile
//   - sets up needed filters in order to select the correct pricing for the situation.
