Question

我试图将一些以编程方式生成的测试与node.js中的Mocha测试框架集成。

var Promise = require('promise');

var resolved = Promise.resolve(true);

suite("Synchronously defined suite", function() {
  test("Synchronously defined test", function() {
    return resolved;
  });
});

defer(function() {
  suite("Asynch DEFINED test", function() {
    suiteSetup(function() {
      console.log("Asynch setupSuite running...");
    });

    test("Asynch Test", function() {
      console.log("Async test running...");
      return resolved;
    });
  });
});

function defer(fn) {
  console.log("Calling defer...");
  setTimeout(fn, 100);
}

当我执行此操作时，我得到：

$ mocha --ui tdd nested-test.js 
Calling defer...


  Synchronously defined suite
    ✓ Synchronously defined test


  1 passing (4ms)

似乎Mocha要求所有＆＃34;套件＆＃34;函数在模块加载时同步执行 - 延迟调用似乎（默默地）被忽略（或程序在调用之前退出）。

这是我设法提出的。它不会在mocha下运行，而是作为一个独立的节点程序运行：

var Promise = require('promise');
var Mocha = require('mocha');

var resolved = Promise.resolve(true);
var rejected = Promise.reject(new Error("Failing test."));

defer(function() {
  console.log("Programmatic test suite creation.");
  var suite = new Mocha.Suite("Programatic Suite");
  var runner = new Mocha.Runner(suite);
  var reporter = new Mocha.reporters.Spec(runner);

  suite.addTest(new Mocha.Test("My test", function() {
    return resolved;
  }));

  suite.addTest(new Mocha.Test("My (failing) test", function() {
    return rejected;
  }));

  runner.run();
});

function defer(fn) {
  setTimeout(fn, 100);
}

运行时输出：

$ node deferred-test.js 
Programmatic test suite creation.

Programatic Suite
  ✓ My test
  1) My (failing) test

  1 passing (7ms)
  1 failing

  1) Programatic Suite My (failing) test:
     Error: Failing test.
      at Object.<anonymous> (deferred-test.js:5:31)
      at node.js:935:3

我希望能够在我的应用程序中的所有（静态定义的）mocha运行测试套件中包含此测试。

如何以编程方式和异步方式定义Mocha测试？
