[英]Jest error TypeError: (0 , _jest.test) is not a function
I get the error:我收到错误:
TypeError: (0 , _jest.test) is not a function TypeError: (0 , _jest.test) 不是函数
when trying to use npm test
.尝试使用npm test
。
I think it could be related to configurations.我认为这可能与配置有关。 How can I fix this problem?我该如何解决这个问题?
function sum (a, b) {
return a + b
}
export default sum
import sum from '../src/sum.js'
import { test, expect } from 'jest'
test('adds 1 + 2 to equal 3', () => {
expect(sum(1, 2)).toBe(3)
})

I've got it running with flow using我已经使用它在流程中运行
import expect from "expect";
const test = window.test;
Maybe it helps you, too.也许它也对你有帮助。 It seems to make flow treat them both as any
, which is far from perfect, but at least the other parts of the file can be checked.好像是让 flow 把它们都当成any
,这还远远不够完美,但至少文件的其他部分是可以检查的。
A slightly better "solution" is to make an own file my-test.test.js
containing一个稍微好一点的“解决方案”是制作一个自己的文件my-test.test.js
包含
export const test = window.test;
export const expect = window.expect;
test("dummy", () => {});
and use it like并像使用它一样
import {test, expect} from '../my/my-test.test';
This concentrates the ugliness in a single file.这将丑陋集中在一个文件中。
