我花了一段时间才找到这个，所以我想在这里为像我这样使用纱线的人添加它:

yarn test -i "src/components/folderX/folderY/.../Filename.ts" -t "name of test"

文件名在-i后面，testname在-t后面。

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', () => {})

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

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>'

只是一个小插件，因为如果使用。/node_modules/.bin/jest -i…或者只是开玩笑-我…或者NPM测试-我…

如果你在全局安装了jest(如npm install -g jest)，那么只调用jest就可以了，这是一种不太干净的处理依赖关系的方式 如果Jest只安装在包的本地，并且想调用Jest脚本而不需要绕道npm脚本，你可以使用npx Jest -i…=>这正是NPX的目的。它可以节省编写。/node_modules/.bin/....的时间

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.
