Babel 7 by SimenB · Pull Request #7016 · jestjs/jest
NOTE: This is not ready for merge. Opening PR to allow people a place to comment and discuss. NOTE 2: If you are a user of Jest, you do not need this PR in order to use Babel 7 and Jest together - that has worked since Jest 22 released in 2017. This PR is strictly upgrading internals and dropping support for Babel 6. If you have some changes which can help us land this, feel free to open up a PR a
[RFC] Migrate Jest to TypeScript by SimenB · Pull Request #7554 · jestjs/jest
In the lastest State of JS, the one stat that stood out to me was the number of people either using or wanting to use TypeScript (over 46.7% has used and will use it again, 33.7% wants to learn it). And since Babel 7 has support for TypeScript, integrating it into your workflow has become way easier than it used to be. We, the Jest core team, have privately discussed migrating to TypeScript (Jest

babel-jest does not transpile import/export in node_modules when Babel 7 is used · Issue #6229 · facebook/jest · GitHub
🐛 Bug Report I started getting the dreaded SyntaxError: Unexpected token import error again for lodash-es. And I spent hours debugging it, because I already had .babelrc and package.json:jest configured properly ("modules": "commonjs", a jest.transform for babel-jest, and transformIgnorePatterns set to not ignore node_modules/lodash-es). After a lot of debugging and a little searching, it appears
Atomic Designでのテストを考える【初級】 - Qiita
概要 初Atomic Designを導入して開発をしてて、どこにどうやってテスト書けばいいんだっけ？ という旨の備忘録です。 仕様言語とかツールとか TypeScript React+Redux redux-saga Jest AtomicDesign ※Atomic Designの説明はしません（Atomic Designの説明はこちらが分かりやすいです） ※超初歩&限定的な内容な気がするので、書いてないメソッドやパターンについては適宜調べていただけると嬉しいです 概要 Jestを使います。 やること インタラクションテスト ロジックテスト テスト対象 AtomicDesignにより分類された各コンポーネント 本記事での例題はatomsのButton インタラクションテストする Reducer ロジックテストする 対象外 middleware 別途書く予定です Jestって？ 公式HP
getComputedStyle()がJestで期待通りに動作しない件について - Qiita
概要 Jestでテストを行った際にSVG要素の属性値を取得できなかったため、モックで対処した件の覚書。 ソースコード import React from 'react'; class App extends React.Component { getWidthFromDiv() { const computedStyle = window.getComputedStyle(this.refDiv); const widthInString = computedStyle.getPropertyValue('width'); const widthInInt = parseInt(widthInString); console.log("div.width:", widthInInt); console.log("window.getComputedStyle(div):", compute
TypeScriptとioredisのコードをJestでテストしたらコンストラクタじゃないと言われた件 - Qiita
📝 TypeScript と ioredis のソースコード TypeScript で Redis 使いたい場合は ioredis で書いてこんな感じのコードになる（ちなみに ES6 で Promise 導入されてからはレガシーなままの node_redis 使ってる人も少ないと思う）。 sample.ts import * as Redis from 'ioredis'; (async () => { const redis = new Redis(); const pong = await redis.ping(); // => PONG })(); import * as Redis from 'ioredis'; describe('Redis', () => { it('should be reply pong', async () => { const redis = new
