正如前面的回答所述，您可以运行该命令

jest -t 'fix-order-test'

如果你在描述块中有一个it，你必须运行

jest -t '<describeString> <itString>'

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.

您还可以使用f或x来集中或排除一个测试。例如

fit('only this test will run', () => {
   expect(true).toBe(false);
});

it('this test will not run', () => {
   expect(true).toBe(false);
});

xit('this test will be ignored', () => {
   expect(true).toBe(false);
});

https://jestjs.io/docs/cli#--testnamepatternregex

你的测试是这个文件my。test。js

test("My Sum", () => {
  const sum = 3;
  expect(sum).toBe(3);
});

以测试名在CLI上运行

jest -t Sum

使用npm测试与regex匹配部分文件名的例子:my.test.js

npm test -t my

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。

对于VSCode，你可以使用joke -run-it扩展，它将帮助你从编辑器中运行和调试Jest测试。
