Я пытаюсь заставить декораторы JavaScript работать с использованием Jest и Babel:
. / Package.json
[...]
"devDependencies": {
[...]
"@babel/core": "7.2.2",
"@babel/plugin-proposal-class-properties": "^7.3.0",
"@babel/plugin-proposal-decorators": "^7.3.0",
"@babel/preset-env": "^7.3.1",
[...]
"jest": "^24.1.0"
},
[...]
"scripts": {
[...]
"jest --no-cache --verbose --config ./test/unit/jest.json"
}
. / Test/unit/.babelrc
{
"presets": [
[
"@babel/preset-env", {
"targets": {
"node": "current"
},
"modules": "commonjs",
"loose": true,
"debug": true
}
]
],
"plugins": [
["@babel/plugin-proposal-decorators", { "legacy": true }],
["@babel/plugin-proposal-class-properties", { "loose": true}]
]
}
. / test / unit / jest.json
{
"modulePaths": [
"<rootDir>/../../src",
"<rootDir>/../../node_modules"
],
"moduleFileExtensions": [
"js",
"json"
],
"testRegex": "\\.spec\\.js$",
"setupFiles": [
"<rootDir>/jest.js"
],
"testEnvironment": "node"
}
. / test / unit /jest.js
import 'aurelia-polyfills';
import {Options} from 'aurelia-loader-nodejs';
import {globalize} from 'aurelia-pal-nodejs';
import * as path from 'path';
Options.relativeToDir = path.join(__dirname, '../../src');
globalize();
Когда я запускаю yarn test
, я получаю:
yarn run v1.12.3
$ jest --no-cache --verbose --config ./test/unit/jest.json
@babel/preset-env: `DEBUG` option
Using targets:
{
"node": "11.9"
}
Using modules transform: commonjs
Using plugins:
syntax-async-generators { "node":"11.9" }
syntax-object-rest-spread { "node":"11.9" }
syntax-json-strings { "node":"11.9" }
syntax-optional-catch-binding { "node":"11.9" }
Using polyfills: No polyfills were added, since the `useBuiltIns` option was not set.
