Question

我有以下测试代码，用于验证在调用返回promise的函数后，生成的数组与存根的数组相同。

it('Should return locations', () => {
  const result = loginSvc.getLocations()

  expect(result).to.eventually.eql(['location1', 'asd', 'location3', 'location4', 'location5'])   
})

loginSvc.getLocations()只是一个被模拟的函数并返回一个数组：['location1', 'location2', 'location3', 'location4', 'location5']

当我运行测试时，它不会失败，因为它应该甚至成功作为误报，并且在控制台中我得到了这个：

错误日志：'未处理的拒绝承诺'，AssertionError {message：'expected [Array（5）]与[Array（5）]具有相同的成员，showDiff：true，actual：['location1'，' location2'，'location3'，'location4'，'location5']，预期：['location1'，'asd'，'location3'，'location4'，'location5']，堆叠：'AssertionError @ http://localhost:9000/base/node_modules/chai/chai.js?40e7aa72e9665366bfd82579520de4fb0754dfae:9320:24 断言@ http://localhost:9000/base/node_modules/chai/chai.js?40e7aa72e9665366bfd82579520de4fb0754dfae:239:31 somethingMethod @ http://localhost:9000/base/node_modules/chai-things/lib/chai-things.js?da5f13ef7d7d30f512b1cd8c3a12b3ed43cd7d31:97:30 overwritingMethodWrapper @ http://localhost:9000/base/node_modules/chai/chai.js?40e7aa72e9665366bfd82579520de4fb0754dfae:8932:38 allMethod @ http://localhost:9000/base/node_modules/chai-things/lib/chai-things.js?da5f13ef7d7d30f512b1cd8c3a12b3ed43cd7d31:165:30 overwritingMethodWrapper @ http://localhost:9000/base/node_modules/chai/chai.js?40e7aa72e9665366bfd82579520de4fb0754dfae:8932:38 http://localhost:9000/base/node_modules/chai/chai.js?40e7aa72e9665366bfd82579520de4fb0754dfae:3379:16 methodWrapper @ http://localhost:9000/base/node_modules/chai/chai.js?40e7aa72e9665366bfd82579520de4fb0754dfae:7709:30 http://localhost:9000/base/node_modules/chai-as-promised/lib/chai-as-promised.js?ac71de40b7ca85a0488f7d3c971a22ddd0e149a8:308:31 运行@ http://localhost:9000/base/spec.js?20bf9e1ddf32e8fc2bfe38226be11b7e65336abf:72447:29 http://localhost:9000/base/spec.js?20bf9e1ddf32e8fc2bfe38226be11b7e65336abf:72460:33 flush @ http://localhost:9000/base/spec.js?20bf9e1ddf32e8fc2bfe38226be11b7e65336abf:72685:11'，line：243，sourceURL：'http://localhost:9000/base/node_modules/chai/chai.js?40e7aa72e9665366bfd82579520de4fb0754dfae'}

但测试通过了

我相信我找到了解决方案，或者更确切地说是解决方法：

it('Should return locations', done => {
  loginSvc.getLocations()
    .then(locations => {
      expect(locations ).to.eql(['location1', 'asd', 'location3', 'location4', 'location5'])
      done()
    })
    .catch(done)
})

Chai将错误记录到控制台而不是测试失败
