查看文档，我们看到简单地使用:

mocha test/myfile

将工作。你可以省略结尾的'.js'。

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.

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

只在“describe”，“it”或“context”之前使用。我使用“$npm run test:unit”运行，它只执行带有.only的单元。

describe.only('get success', function() {
 // ...
});

it.only('should return 1', function() {
  // ...
});

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。

你可以试试"it.only"

it.only('Test one ', () => {
            
    expect(x).to.equal(y);
});

it('Test two ', () => {
            
    expect(x).to.equal(y);
});

在这种情况下，只执行第一个
