BILLING TESTING

General idea

We have tests of different levels:

• unit tests for in-class functionality (done in every package)
• BDD-tests for charges calculation for all expected cases (done in php-billing and specific billing implementations)
• PACTs for API interactions
• acceptance tests for billing is really properly calculated for manually created cases

Acceptance tests

• insert all the needed billing data:
  • customers and targets - with DB-migrations
    • all billable targets to be covered!
  • plans, sales and resource consumption - through API (tests API)
    • all used plan types to be covered!
• check everything is calculated properly
  • check ad-hoc calculations - through API
  • run billing calculation - throuh CLI (in prod run with CRON)
  • compare calculated values
    • get bills and charges - through API
    • compare with precalculated values
• clean - through API or DB
  • no need to clean customers and targets
• repeat
• profit
