我想測試的函數(shù)中有一個 try/catch 塊。這兩個函數(shù)調(diào)用同一個execute函數(shù)，如果它拋出錯誤，它們將被捕獲。我的測試是在頂部附近模擬模塊的地方設(shè)置的，然后我可以驗證該 jest 函數(shù)被調(diào)用了多少次。我似乎無法弄清楚的是如何強制 execute在第二次測試中拋出錯誤，然后返回到默認的模擬實現(xiàn)。我試過在個人測試中重新分配 jest.mock 但它似乎不起作用。import {execute} from '../src/execute'jest.mock('../src/execute', () => ({  execute: jest.fn()}))describe('git', () => {  afterEach(() => {    Object.assign(action, JSON.parse(originalAction))  })  describe('init', () => {    it('should stash changes if preserve is true', async () => {      Object.assign(action, {        silent: false,        accessToken: '123',        branch: 'branch',        folder: '.',        preserve: true,        isTest: true,        pusher: {          name: 'asd',          email: 'as@cat'        }      })      await init(action)      expect(execute).toBeCalledTimes(7)    })  })  describe('generateBranch', () => {    it('should execute six commands', async () => {       jest.mock('../src/execute', () => ({         execute: jest.fn().mockImplementation(() => {           throw new Error('throwing here so. I can ensure the error parsed properly');         });      }))      Object.assign(action, {        silent: false,        accessToken: '123',        branch: 'branch',        folder: '.',        pusher: {          name: 'asd',          email: 'as@cat'        }      })            // With how this is setup this should fail but its passing as execute is not throwing an error      await generateBranch(action)      expect(execute).toBeCalledTimes(6)    })  })})
