Вопрос:
В настоящее время существует проблема с импортом es6 в тестовых примерах Mocha. Я пытался добавить babel и последние пресеты, но это ничего не решает. Я попробовал несколько доступных решений, но не смог решить свою проблему.
Это мой package.json `
{
"name": "ep-backend",
"main": "app.js",
"scripts": {
"tsc": "tsc",
"dev": "ts-node-dev --respawn --transpileOnly $NODE_DEBUG_OPTION ./app/app.ts",
"prod": "tsc amp;amp; node ./build/app.js",
"test": "NODE_DEBUG="fs" DEBUG="*" mocha --require @babel/register $(find test -name '*.ts')"
},
"license": "ISC",
"dependencies": {
"@types/express": "^4.16.1",
"axios": "^0.18.0",
"chai": "^4.2.0",
"chai-http": "^4.2.1",
"dotenv": "^7.0.0",
"express": "^4.16.4",
"http-status-codes": "^1.3.1",
"mocha": "^6.0.2",
"nock": "^10.0.6",
"ts-node-dev": "^1.0.0-pre.32",
"typescript": "^3.3.3333"
},
"devDependencies": {
"@babel/core": "^7.4.0",
"@babel/register": "^7.4.0",
"babel-preset-es2015": "^6.24.1",
"babel-preset-latest": "^6.24.1"
},
"babel": {
"presets": [
"latest"
]
}
}
`
это структура моего проекта
ep-backend -> app -> services -> service.ts
ep-backend -> package.json
ep-backend -> tsconfig.json
ep-backend -> .babelrc
ep-backend -> test -> services -> service.test.ts
Содержимое .babelrc является
`{ "presets": ["latest"]}`
мой tsconfig.json `
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"outDir": "./build",
"esModuleInterop": true
}
}
`
В моем service.test.ts я импортирую service.ts как
import { getAllTests, createTest, getTestByID } from "../../app/services/replicar-service";
Мой журнал ошибок консоли
NODE_DEBUG="fs" DEBUG="*" mocha --require @babel/register $(find test -name '*.ts')

Ответ №1:
Из документации @babel/register , .es6, .es, .jsx, .mjs, and .js are the only extensions will be processed by default . Вы можете переопределить это, потребовав модуль в вашем тестовом файле. Проверьте следующий URL, чтобы увидеть доступные параметры.
