mocha中的'it'不會在使用await時運行

Question

mocha中的“it”不會使用await運行。

我使用函數異步讀取文件並根據返回的值運行多個循環來處理我的測試。 我還在循環中多次使用相同的文件讀取函數。 我需要使用await來從該函數中獲取已解析的值。 如果我刪除await然后“it”運行但我的功能仍未解決。

const subList1 = [
    {name: 'value1', info: 'value1'},
    {name: 'value2', info: 'value2'},
    {name: 'value3', info: 'value3'},
]
const subList2 = [
    {name: 'value1', info: 'value1'},
    {name: 'value2', info: 'value2'},
    {name: 'value3', info: 'value3'},
]
const subList3 = [
    {name: 'value1', info: 'value1'},
    {name: 'value2', info: 'value2'},
    {name: 'value3', info: 'value3'},
]

const mainList = [
    subList1, subList2, subList3, 
    ]

function getList() {
    return mainList;
}

describe('Test', async function () {
    const list = await getList();
    list.forEach(mainListItem => {
        describe('Main Test', function () {
            mainListItem.forEach(subListItem => {
                describe(subListItem.name, function () {
                    let valueInCaps;
                    const name = subListItem.name;
                    console.log(`name: ${JSON.stringify(name)}`);
                    before(function () {
                        valueInCaps = subListItem.info.toUpperCase();
                    })
                    it(name, function () {
                        console.log(valueInCaps);
                    })
                })
            })

        });
    });
})

預期：

name: "value1"
name: "value2"
name: "value3"
name: "value1"
name: "value2"
name: "value3"
name: "value1"
name: "value2"
name: "value3"


  Test
    Main Test
      value1
VALUE1
        √ value1
      value2
VALUE2
        √ value2
      value3
VALUE3
        √ value3
    Main Test
      value1
VALUE1
        √ value1
      value2
VALUE2
        √ value2
      value3
VALUE3
        √ value3
    Main Test
      value1
VALUE1
        √ value1
      value2
VALUE2
        √ value2
      value3
VALUE3
        √ value3

實際：

name: "value1" name: "value2" name: "value3" name: "value1" name: "value2" name: "value3" name: "value1" name: "value2" name: "value3"

如果你進入摩卡網站，你會找到一個如何構建測試的好例子。 我相信你的問題是你沒有在測試中斷言任何東西。 你沒有測試任何假設。

// require an assertion library
var assert = require('assert');

    describe('Test', async function () {
        const list = await getList();
        list.forEach(mainListItem => {
            describe('Main Test', function () {
                mainListItem.forEach(subListItem => {
                    describe(subListItem.name, function () {
                        let valueInCaps;
                        const name = subListItem.name;
                        console.log(`name: ${JSON.stringify(name)}`);
                        before(function () {
                            valueInCaps = subListItem.info.toUpperCase();
                        })
                        it(name, function () {
                            console.log(valueInCaps);
                            assert.equal(someCondition)
                        })
                    })
                })

            });
        });
    })
