Question

でユニットテストを行うとき、私は活字体でかなり新しいですし、このチュートリアル以下のプロジェクトを設定しようとしていたが見つかりません。 test.tsを実行し、npm testを実行してapiの基本的なルートが動作しているかどうかを確認します。私はNPMテストコマンド（実行します。mocha --reporter spec --compilers ts:ts-node/register 'test/**/*.test.ts'）を実行したときに

は、しかし、私は、次のエラーを取得：テスト/ helloworld.test.tsの

チュートリアル（https://github.com/mjhea0/typescript-node-api）からレポを複製する際に同じ問題があります。

npmパッケージを正しくインストールすると、npmを起動するとapiが正しく動作していると思います。

私のファイルは基本的にrepoのファイルとほぼ同じなので、この記事にいくつかのファイルを追加してください。私はUbuntuの16.04、私のノードのバージョンを使用しています

は7.0.0私のNPMバージョンである私は再現でき3.10.10とチュートリアル利用typescriptです2.

Answer 1

です。 ts-nodeは働い
