小编mdi*_*kin的帖子

今天就参加，但是我无法将解决方案添加到Visual Studio论坛中：https : //developercommunity.visualstudio.com/content/problem/17952/team-explorer-git-compare-with-unmodified-not-work .html

import ims.repository.invoice_repository as invoiceRepository
import logging

logger = logging.getLogger(__name__)

def update_invoice_statuses(invoices):
    for invoice in invoices:

            continue;

test_invoice_business.py

import logging
import ims.business.invoice_business as business

class UpdateInvoiceTests(TestCase):
    @mock.patch("ims.business.invoice_business.invoiceRepository")
    @mock.patch("ims.business.invoice_business.logger")
    def test_invoiceDoesNotExist_logsErrorAndContinues(self, invoiceRepoMock, loggerMock):
        #Arrange
        invoice = Invoice(123)
        invoice.set_status(InvoiceStatus.Filed, None)
        invoiceRepoMock.get.return_value(33)

        #Act
        business.update_invoice_statuses([invoice])

        #Assert …
