如何检查类继承在Coffeescript摩卡测试？ [英] How to check for class inheritance in Coffeescript Mocha Test?

问题描述

如何在Coffeescript中检查mocha规范中的对象的类？

How do I check for the class of an object in a mocha spec in Coffeescript?

我尝试过以下操作：

# foo.coffee
class Foo
module.exports = new Foo()

# foo_spec.coffee
should  = require 'should'
{ Foo } = require 'foo'
foo = new Foo
foo.should.be.an.instanceOf(Foo)

$ b b

但是，我收到 ReferenceError Foo未定义

推荐答案

我相信这是最简单的方法：

I believe this to be the easiest approach:

# foo.coffee
class Foo
module.exports = new Foo()
module.exports.Foo = Foo # IMPORTANT, exports the actual class Foo


# foo_spec.coffee
should  = require 'should'
{ Foo } = require 'foo' # Requires said class Foo
foo = new Foo
foo.should.be.an.instanceOf(Foo)
