这是我的存根方法

Question

export function mockGetTransactions() {
    sinon.stub(TransactionsService, 'getTransactions').resolves(mockTransactions('0071326981')) 
}

最后是模拟数据

export function mockTransactions(account: string) {
  return {
    date: faker.date.recent(3),
    transaction_type: 'credit',
    amount: mockAmount(10000, 1000000, 4),
    remark: faker.random.words(10),
    reference: faker.random.words(5),
    nuban: account,
  };
}
这是我得到的错误

TypeScript diagnostics (customize using `[jest-config].globals.ts-jest.diagnostics` option):
    __tests__/mocks/services/transaction.ts:6:65 - error TS2345: Argument of type '{ date: Date; transaction_type: string; amount: number; remark: string; reference: string; nuban: string; }' is not assignable to parameter of type 'Transaction[]'.
      Type '{ date: Date; transaction_type: string; amount: number; remark: string; reference: string; nuban: string; }' is missing the following properties from type 'Transaction[]': length, pop, push, concat, and 26 more.

    6     sinon.stub(TransactionsService, 'getTransactions').resolves(mockTransactions('0071326981'))

所以getTransactions期望使用Transaction []即Transaction数组，而我正在传递带有模拟交易的对象

这是我正在存根类服务Service {
看起来您的getTransactions方法期望使用事务[]，因此您应该能够修改模拟数据以返回包含事务对象的数组。
