对于最新的Jest版本，您可以使用以下方法之一仅运行一个测试，对于测试套件也是如此。

it.only('test 1', () => {})

test.only('test 1', () => {})

fit('test 1', () => {})

如果测试名称是唯一的，开玩笑的“test 1”也可以工作。

在Visual Studio Code中，这让我只能运行/调试一个带有断点的Jest测试:在Visual Studio Code中调试测试

我的发射。Json文件里面有这个:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Jest All",
      "program": "${workspaceFolder}/node_modules/.bin/jest",
      "args": ["--runInBand"],
      "console": "integratedTerminal",
      "internalConsoleOptions": "neverOpen",
      "windows": {
        "program": "${workspaceFolder}/node_modules/jest/bin/jest",
      }
    },
    {
      "type": "node",
      "request": "launch",
      "name": "Jest Current File",
      "program": "${workspaceFolder}/node_modules/.bin/jest",
      "args": ["${relativeFile}"],
      "console": "integratedTerminal",
      "internalConsoleOptions": "neverOpen",
      "windows": {
        "program": "${workspaceFolder}/node_modules/jest/bin/jest",
      }
    }
  ]
}

在package.json文件中:

  "scripts": {
    "test": "jest"
  }

要运行一个测试，在该测试中，将test(或it)更改为test。只有(或it.only)。若要运行一个测试套件(多个测试)，请将describe更改为description .only。 如果需要，可以设置断点。 在Visual Studio Code中，转到调试视图(Shift + Cmd + D或Shift + Ctrl + D)。 从顶部的下拉菜单中，选择笑话当前文件。 单击绿色箭头以运行该测试。

运行命令行:

   npm run test-jest unit_test/file_name -- -t test_name

我Package.json

"test-jest": "jest --verbose=true --force-exit",
"test-jest:watch": "jest --watchAll",

以下是我的看法:

./node_modules/.bin/jest --config test/jest-unit-config.json --runInBand src/components/OpenForm/OpenForm.spec.js -t 'show expanded'

注:

./node_modules/.bin/... is a wonderful way, to access the locally installed Jest (or Mocha or...) binary that came with the locally installed package. (Yes, in your npm scripts you can jest with nothing before, but this is handy on command line... (that's also a good start for your debugging config, whichever IDE you are using...) Your project might not have a set of configuration options. But if it does (peek into the scripts in package.json), this is, what you need. --runInBand – as said, don't know about your configuration, but if you concentrate on developing/fixing a single test, you rather do not want to deal with web workers... Yes, you can give the whole, explicit path to your file Optionally, you can use -t to not run all tests in that file, but only a single one (here: the one, that has something with ‘show expanded’ in its name). Same effect can be achieved by glueing .only() into that file.

Use:

npm run test -- test-name

只有当您的测试规范名称是唯一的时，这才会起作用。

上面的代码将引用一个名为test-name.component.spec.ts的文件

你可以尝试使用下面的命令，因为它对我有用

npm run test -- -t 'Your test name'

或者你可以像下面这样在测试中添加.only，然后运行npm run test命令

it.only('Your test name', () => {})
