我在fix-order-test.js文件中有一个测试“works with nested children”。

运行下面的代码将运行文件中的所有测试。

jest fix-order-test

如何只运行一个测试?下面的方法无法工作,因为它搜索指定的正则表达式的文件。

jest 'works with nested children'

当前回答

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.

其他回答

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', () => {})

在检查了Jest CLI文档之后,我发现这就是我们在特定文件中运行特定测试的方式。

jest --findRelatedTests path/to/fileA.js path/to/fileB.js -t "test name"

纱,

yarn test --findRelatedTests path/to/fileA.js path/to/fileB.js -t "test name"

npm,

npm test -- --findRelatedTests path/to/fileA.js path/to/fileB.js -t "test name"

如需参考,请检查Jest Cli选项

Jest文档建议如下:

如果测试失败,首先要检查的事情之一应该是 当测试是唯一运行的测试时,测试是否失败。在开玩笑 只运行一个测试很简单——只是临时更改该测试 命令到test.only

test.only('this will be the only test that runs', () => {
   expect(true).toBe(false);
});

or

it.only('this will be the only test that runs', () => {
   expect(true).toBe(false);
});

在最新版本的jest中,您可以以多种方式运行任何单个测试。

fit('only this test will run', () => {});

it.only('only this test will run',() => {});

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>'
