Question

我写了一小段代码来了解sinon功能。

下面是要检查的代码段：

{-2*x/5}

我期望console.log输出为模拟响应。但是它以TEST作为响应。

Answer 1

这是单元测试解决方案：

index.js：

const getAuthenticationInfo = orgId => {
  return 'TEST';
};
const getAuthToken = orgId => {
  var lmsInfo = exports.getAuthenticationInfo(orgId);
  return lmsInfo;
};

exports.getAuthenticationInfo = getAuthenticationInfo;
exports.getAuthToken = getAuthToken;

index.spec.js：

const mod = require('./');
const sinon = require('sinon');
const { expect } = require('chai');

describe('53605161', () => {
  it('should stub getAuthenticationInfo correctly', () => {
    const stub = sinon.stub(mod, 'getAuthenticationInfo').returns('mocked-response');
    const actual = mod.getAuthToken(1);
    expect(actual).to.be.equal('mocked-response');
    expect(stub.calledWith(1)).to.be.true;
    stub.restore();
  });

  it('getAuthenticationInfo', () => {
    const actual = mod.getAuthenticationInfo();
    expect(actual).to.be.equal('TEST');
  });
});

具有100％覆盖率报告的单元测试结果：

 53605161
    ✓ should stub getAuthenticationInfo correctly
    ✓ getAuthenticationInfo
