node.js - 如何构建等待进程首先完成的 Mocha 测试？

Question

我正在尝试为我的 Yeoman 生成器编写一个测试，它调用命令行实用程序在我正在搭建的文件夹中生成一些文件。我已经看到了如何设置超时以等待函数完成的各种示例，但我正在努力让它在本地工作。

这是我的测试:

 describe('Should properly scaffold with config for Spring and wsdl2rest', function () {

    before(function () {
      basicProps.name = 'MyAppMock';
      basicProps.package = 'com.generator.mock';
      basicProps.camelVersion = '2.18.2';
      basicProps.camelDSL = 'spring';
      var wsdlPath = path.join(__dirname, '../test/address.wsdl');
      basicProps.wsdl = wsdlPath;
      basicProps.outdirectory = 'src/main/java';

      return helpers.run(path.join(__dirname, '../app'))
        .inTmpDir(function (dir) {
          var done = this.async(); // `this` is the RunContext object.
          fs.copy(path.join(__dirname, '../templates'), dir, done);
          basicProps.outdirectory = path.join(dir, 'src/main/java');
        })
        .withOptions({ wsdl2rest: true })
        .withPrompts({ name: basicProps.name })
        .withPrompts({ camelVersion: basicProps.camelVersion })
        .withPrompts({ camelDSL: basicProps.camelDSL })
        .withPrompts({ package: basicProps.package })
        .withPrompts({ wsdl: basicProps.wsdl })
        .withPrompts({ outdirectory: basicProps.outdirectory })
        .toPromise();
    });

    it('Should create the basic structure two ways', function () {
      assert.file('pom.xml');
      assert.file('README.md');
      assert.file('src/main/resources/META-INF/spring/camel-context.xml');
      assert.file('src/main/resources/META-INF/spring/camel-context-rest.xml')
    });
  });

问题是命令行可执行文件在测试后完成，以查看它生成的文件是否存在，所以我得到:

wsdl2rest generated artifacts successfully

让这个东西等待的秘诀是什么？我确信我错过了一些明显的东西，但我主要是一名 Java 程序员而不是 JavaScript，并且在该语言的一些异步方面遇到了一些困难。

提前致谢!

更新:虽然有人建议我使用 Mocha 的异步代码选项 ( https://mochajs.org/#asynchronous-code )，但我很难将这些概念融入到我编写的测试中，如果有人用 Yeoman 解决了这个问题，我可以使用一些额外的帮助发电机测试？

在这里查看 Mocha 文档 - https://mochajs.org/#asynchronous-hooks

似乎您可能需要将“之前”放在“描述”之外。或者，您可以将“it”包装在另一个“describe”中。
