やりたいこと
JavaScriptまたはTypeScriptのES6モジュールをJestテストする方法のメモです.
Jestの設定(JavaScriptの場合)
Jestをインストールする.
npm install --save-dev jest
package.jsonファイル内に”script”と”type”のスクリプトを追加する.
{
"name": "",
"version": "",
"description": "",
"main": "index.js",
"directories": {
"test": "test"
},
"scripts": {
"test": "node --experimental-vm-modules node_modules/jest/bin/jest.js"
},
"type": "module",
"author": "",
"license": "",
"devDependencies": {
"jest": "^26.6.3"
}
}
jest.config.jsファイルを作成し,以下のスクリプトを書き込む.
export default {
testEnvironment: 'jest-environment-node',
transform: {}
};
以下のコマンドでJestテストを実行する.
npm test
Jestの設定(TypeScriptの場合)
Jestと関連するモジュールをインストールする.
npm install --save-dev jest ts-jest @types/jest
以下のコマンドでjest.configファイルを作成する. jest.configファイルをTypeScriptにすると,ts-nodeが追加で必要になるので,JavaScriptを指定する.
npx jest --init
√ Would you like to use Typescript for the configuration file? ... no
√ Choose the test environment that will be used for testing » node
√ Do you want Jest to add coverage reports? ... yes
√ Which provider should be used to instrument code for coverage? » v8
√ Automatically clear mock calls, instances and results before every test? ... no
jest.config.jsに以下のスクリプトを追加する.
// The glob patterns Jest uses to detect test files
testMatch: [
"**/__tests__/**/*.[jt]s?(x)",
"**/?(*.)+(spec|test).[tj]s?(x)"
],
// A map from regular expressions to paths to transformers
transform: {
"^.+\\.(ts|tsx)$": "ts-jest",
},
package.jsonファイルに以下のスクリプトを追加.
"scripts": {
"test": "jest"
},
tsconfig.jsonファイルにはesModuleInteropのスクリプトを追加.
{
"compilerOptions": {
"lib": ["es6", "dom"],
"moduleResolution": "node",
"module": "es6",
"outDir": "dist",
"sourceMap": true,
"strict": true,
"esModuleInterop": true,
"target": "es6",
"allowJs": true
},
"include": [
"src", "lib"
]
}
以下のコマンドでJestテストを実行する.
npm test
