Mocha单元测试Promise throws错误

mocha unit-testing node.js

iJade · 技术社区 · 6 年前

我在试着对一个承诺进行单元测试。代码如下:

it('it should return some 10 user data with ok status code when called with url ', (done) => {
    return user.getUsers('https://jsonplaceholder.typicode.com/users')
    .then((response) => {
        console.log('me here')
        assert.equal(JSON.parse(response).length, 10)
    })
    .catch((err)=>{
        console.log('me in error')
        assert.fail('err')
    })
})

运行时上述代码引发以下错误: Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (C:\Users\ajay\jay-workspace\UniTestModule\test\user.test.js)

done

it('it should return some 10 user data with ok status code when called with url ', () => {
    return user.getUsers('https://jsonplaceholder.typicode.com/users')
    .then((response) => {
        console.log('me here')
        assert.equal(JSON.parse(response).length, 10)
    });
})

assert.fail
