[ENG-834] Testcases for invoice - #3726
Conversation
📝 WalkthroughWalkthroughThe PR expands invoice API tests across creation, updates, listing, retrieval, cancellation, charge-item operations, locking, and account attachment. It also adds user creation tests for password-reset email delivery and password state. ChangesInvoice and User API coverage

Pull request overview
Adds/expands Django REST Framework API test coverage for the EMR invoice endpoints (create/update/list/retrieve/cancel/lock + permission and validation scenarios) to support ENG-834.
Changes:
- Refactors invoice API tests into a shared helper-based test class and adds broad endpoint coverage.
- Adds tests for invoice numbering defaults, create-lock failure handling, and multiple status-transition validations.
- Adds tests for payment-reconciliation-related invoice filtering and locked-invoice permission behavior.

The suite covers permissions and non-draft status for attach, but no test attaches a charge item that belongs to a different account or facility. That is a tenant-isolation boundary, and it is the kind of thing that only gets noticed after it ships. A single negative test would cover it.

In `@care/emr/tests/test_invoice_api.py`:
- Around line 1255-1266: Update test_attach_account_to_invoice_as_superuser and
test_attach_account_to_invoice_as_user_with_permissions to create an additional
billable charge item on the account after create_invoice, ensuring it is not
initially attached to the invoice. Assert that this new item appears in
response.data["charge_items"] after the request, rather than asserting the
pre-attached self.charge_item.
- Around line 563-579: The invoice list tests, including
test_list_invoices_with_account_filter and
test_list_invoices_with_payment_reconciliation_present_filter_and_account, do
not prove account filtering because only self.account has an invoice. Extend
create_invoice to accept an account override, create a second account and
invoice for it in both tests, then assert the requested account’s result
contains only the expected invoice and excludes the second account’s invoice.
- Around line 346-364: Update
test_update_invoice_with_no_charge_items_and_issued_status so the generated
request data explicitly contains an empty charge_items list, while preserving
the issued status. Ensure the PUT payload matches the invoice created with
charge_items=[] and continues asserting the existing 400 response and validation
message.
- Around line 1284-1287: Correct the docstring in
test_attach_account_to_invoice_as_user_without_permissions to describe a user
without write permission, matching the test name and covered scenario.
- Around line 706-757: Rename all three test methods beginning with
test_retrive_locked_invoice—test_retrive_locked_invoice_with_superuser,
test_retrive_locked_invoice_with_user_without_permission, and
test_retrive_locked_invoice_with_user_with_permission—to use
test_retrieve_locked_invoice, preserving their behavior and test coverage.
- Around line 168-182: Strengthen
test_create_invoice_without_number_auto_generates by asserting
response.data["number"] equals the value produced by the configured expression,
including the expected INV- prefix, invoice count, and two-digit current year,
rather than only checking that it is truthy.
- Around line 894-910: Update
test_cancel_invoice_with_user_without_permission_outside_period to apply
`@override_settings`(INVOICE_FREE_CANCEL_PERIOD_MINUTES=5), ensuring the invoice
created 10 minutes earlier remains outside the free-cancel period and the 403
assertion exercises the destroy-permission path.
