运行玩笑测试时无法附加调试器

Question

我无法在运行玩笑测试时附加 VS Code 调试器。我尝试使用launch.json找到的不同替代方案配置文件，但它们总是失败并显示以下错误消息，抱怨 node_modules 文件夹中的文件：

Debugger attached.
Waiting for the debugger to disconnect...
local\path\to\node_modules\.bin\jest:2
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")
          ^^^^^^^

SyntaxError: missing ) after argument list
    at wrapSafe (internal/modules/cjs/loader.js:979:16)
    at Module._compile (internal/modules/cjs/loader.js:1027:27)

    at Module.load (internal/modules/cjs/loader.js:928:32)
    at Function.Module._load (internal/modules/cjs/loader.js:769:14)
    at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:72:12)      
    at internal/main/run_main_module.js:17:47

我的package.json文件具有以下配置：

Debugger attached.
Waiting for the debugger to disconnect...
local\path\to\node_modules\.bin\jest:2
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")
          ^^^^^^^

    at internal/main/run_main_module.js:17:47

我的launch.json：

  "scripts": {
    "compile": "tsc",
    "run": "node ./build/index.js",
    "execute": "tsc && node ./build/index.js",
    "test": "tsc && jest ./build/tests/*"
  },

  },
  "devDependencies": {
    "@types/node": "^14.14.21",
    "jest": "^26.6.3"
  }

如果有帮助，执行npm run test通常会运行我的笑话测试，所以我不确定它是否与笑话本身有关。

Answer 1

Windows 上似乎存在一个错误，解决方案是将 VS Code 直接指向 jest.js 而不是 .bin 版本：

所以尝试替换这个：

"runtimeArgs": ["--inspect-brk", "${workspaceRoot}/node_modules/.bin/jest", "--runInBand"], 类似的东西：

"runtimeArgs": ["--inspect-brk", "${workspaceRoot}/node_modules/jest/bin/jest.js", "--runInBand", "--coverage", "false"],

https://github.com/facebook/jest/issues/3750

另外，如果您遇到有关 jest 配置的另一个错误，请添加参数-c：

  "args": [
              "--runInBand",
              "-c", "${workspaceFolder}/package/jest.config.js",
            ],

Answer 2

我通过安装 ts-jest 并在launch.json.

{
  "type": "node",
  "request": "launch",
  "name": "Jest All",
  "program": "${workspaceFolder}/node_modules/.bin/jest",
  "args": [
    "--runInBand"
  ],
  "console": "integratedTerminal",
  "internalConsoleOptions": "neverOpen",
  "disableOptimisticBPs": true,
  "windows": {
    "program": "${workspaceFolder}/node_modules/jest/bin/jest",
  }
},
