我发现最快/最简单的方法是用

npx 是 TheNameOfYourFile

此外，您可以“订阅”以继续阅读更改

npx 是 TheNameOfYourFile --watchAll

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', () => {})

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.

在命令行中，使用——testnameppattern或-t标志:

jest -t 'fix-order-test'

这将只运行与您提供的测试名称模式匹配的测试。它在Jest文档中。

另一种方法是在监视模式下运行测试，jest—watch，然后按P来过滤测试，输入测试文件名或T来运行单个测试名称。

如果你在描述块中有一个it，你必须运行

jest -t '<describeString> <itString>'

现在有一个很好的Jest插件，叫做joke -watch-typeahead，它使这个过程更加简单。

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);
});
