有多种方法可以做到这一点。

If you just want to run one test from your entire list of test cases then, you can write only ahead of your test case. it.only('<test scenario name>', function() { // ... }); or you can also execute the mocha grep command as below mocha -g <test-scenario-name> If you want to run all the test cases which are inside one describe section, then you can also write only to describe as well. describe.only('<Description of the tests under this section>', function() { // ... }); If you have multiple test files & you wanted to run only one of then you can follow the below command. npm test <filepath> eg : npm test test/api/controllers/test.js here 'test/api/controllers/test.js' is filepath.

执行single test - by filename -

实际上，如果你从你的mocha中删除glob模式(例如./test/**/*.spec.js)，你也可以通过文件名(而不仅仅是通过" it()-string-grepping ")来运行一个单独的mocha测试。选项，分别创建一个副本，没有:

node_modules/.bin/mocha --opts test/mocha.single.opts test/self-test.spec.js

这是我的mocha.single.opts(唯一的不同是错过了前面提到的glob行)

--require ./test/common.js
--compilers js:babel-core/register
--reporter list
--recursive

背景:虽然你可以覆盖options - file中的各种开关(从——开始)，但你不能覆盖glob。这种联系也有 一些解释。

提示:如果node_modules/.bin/mocha让你感到困惑，请使用本地包mocha。你也可以只写mocha，如果你全局安装了它。

如果你想要舒适的包装。仍然:从摩卡中删除**/*-ish glob。选项，将它们插入这里，用于所有测试，将它们留给单个测试:

"test": "mocha ./test/**/*.spec.js",
"test-watch": "mocha -R list -w ./test/**/*.spec.js",
"test-single": "mocha",
"test-single-watch": "mocha -R list -w",

用法:

> npm run test

分别

> npm run test-single -- test/ES6.self-test.spec.js

嗨，上面的解决方案对我不起作用。 运行单个测试的另一种方法是

mocha test/cartcheckout/checkout.js -g 'Test Name Goes here'

这有助于从单个文件和特定名称运行测试用例。

不知道为什么grep方法在使用npm测试时不适合我。不过这是可行的。出于某种原因，我还需要指定测试文件夹。

npm test -- test/sometest.js

如果你使用npm测试(使用包。Json脚本)使用一个额外的——通过mocha传递参数

例如NPM test -- --grep“my second test”

编辑:看起来——grep可能有点麻烦(可能取决于其他参数)。您可以:

修改package.json:

"test:mocha": "mocha --grep \"<DealsList />\" .",

或者使用保释金，这似乎不那么麻烦

npm test -- --bail
