JestのテストコードをVScodeでデバッグする

More than 1 year has passed since last update.

個人メモとして投稿。

まぁざっくり公式を見ればいいのだが、launch.jsonの記述がわりとアレ(別に動きはする)なのでよりシンプルに書いてみた。

.vscode/launch.json
{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug Jest Tests",
            "type": "node",
            "request": "launch",
            "program": "${workspaceRoot}/node_modules/.bin/jest",
            "protocol": "inspector",
            "args": [ "--runInBand" ],
            "windows": {
                "program": "${workspaceRoot}/node_modules/jest/bin/jest.js"
            }
        }
    ]
}

環境上書き用の設定は存在するので、わざわざwindowsで書き換えする必要はありません。
この記述だとコンソールが自動で表示されないのですが、それが気に入らない人は下記の通り書いておけばいいでしょう。

.vscode/launch.json
{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug Jest Tests",
            "type": "node",
            "request": "launch",
            "program": "${workspaceRoot}/node_modules/.bin/jest",
            "protocol": "inspector",
            "args": [ "--runInBand" ],
            "windows": {
                "program": "${workspaceRoot}/node_modules/jest/bin/jest.js"
            },
            "console": "integratedTerminal",
            "internalConsoleOptions": "neverOpen"
        }
    ]
}
