After the creation of the test plan for swatch contracts we need to start implementing the tests.

  This card focuses on the tests covering contract updates via Internal API.

  The following tests need to be implemented:

  contracts-update-TC003 - Update contract start and end date
  contracts-update-TC004 - Update contract end date (renewal)
  contracts-update-TC005 - Update contract metrics for Payg
  contracts-update-TC006 - Update contract metrics from pure payg (no metrics before) to payg (with metrics)
  contracts-update-TC007 - Update contract - terminate (set end date)
  contracts-update-TC008 - Update contract - add new metric
  contracts-update-TC009 - Update contract - remove metric

  Acceptance criteria:

  All 7 test cases (TC003-TC009) from the test plan are implemented and passing locally and in ephemeral environments.
