- In order to test the invoice numbering, I create a sequence for out invoices.
- !record {model: ir.sequence, id: seq_out_invoice_test}:
    name: Account Invoice Out for the demonstration Fiscal Year # XXX indicate the name of the fiscal year
    code: account.invoice.out_invoice
    padding: 3
    prefix: FY-
    suffix: -TEST
    number_next: 42

- I link the new sequence to the demo sequence and the demo fiscal years.
- !record {model: account.sequence.fiscalyear, id: seq_out_invoice_test_fy}:
    sequence_id: seq_out_invoice_test
    sequence_main_id: seq_out_invoice
    fiscalyear_id: data_fiscalyear

- I create a draft customer invoice in a period of the demo fiscal year
- !record {model: account.invoice, id: invoice_seq_test}:
    account_id: account.a_recv
    company_id: base.main_company
    currency_id: base.EUR
    invoice_line:
      - account_id: account.a_sale
        name: '[PC3] Medium PC'
        price_unit: 900.0
        quantity: 10.0
        product_id: product.product_product_5
        uos_id: product.product_uom_unit
    journal_id: account.sales_journal
    partner_id: base.res_partner_3
    reference_type: none
    period_id: period_1
    
- I create the invoice, as I clicked on the "Create" button
- !workflow {model: account.invoice, action: invoice_open, ref: invoice_seq_test}

- I check that the invoice state is "Open"
- !assert {model: account.invoice, id: invoice_seq_test}:
    - state == 'open'
    
- I check that the invoice got the right number using our sequence
  # This used to fail because of bug #602188
- !assert {model: account.invoice, id: invoice_seq_test}:
    - number == 'FY-042-TEST'
