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.

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。

尝试使用摩卡的——grep选项:

    -g, --grep <pattern>            only run tests matching <pattern>

您可以使用任何有效的JavaScript正则表达式作为<pattern>。例如，如果我们有test/mytest.js:

it('logs a', function(done) {
  console.log('a');
  done();
});

it('logs b', function(done) {
  console.log('b');
  done();
});

然后:

$ mocha -g 'logs a'

运行单个测试。注意，这个greps对所有describe(name, fn)和it(name, fn)调用的名称都适用。

考虑对命名空间使用嵌套的describe()调用，以便便于定位和选择特定的集合。

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
