我遇到了针对mocha-cakes服务运行的一些restify测试脚本的时间问题。我使用Restify JSON客户端发出调用，这些调用使用回调而不是promises。我已将完成函数传递给我的Given和When，以便我可以对这些异步调用执行必要的阻止，从而防止测试套件运行不一致（没有dones，它是一个tossup，以及Then和And将通过多少。
我熟练使用coffescript，而且对于mocha / mocha-cake来说只是一个新手，所以我肯定在我的代码中做错了。以下是一些失败的测试用例示例：
require 'mocha-cakes'
should = require 'should'
restify = require 'restify'
Feature "Account API",
"In order to have control over structured Account documents",
"as a consumer of investment account information,",
"I need a RESTful service API.", ->
Scenario "GET /account/:userid", ->
client = restify.createJSONClient
url: "http://localhost:8080",
version: "*"
_e1 = null
_r1 = null
_e2 = null
_r2 = null
_d2 = null
# GET non-existent account
Given "I have not yet created the Account", ->
When "I request the Account", (done) ->
client.get "/account/99", (err, req, res, obj) ->
_e1 = err
_r1 = res
done()
err
Then "it should respond with an error", ->
_e1.should.be.ok
And "the status code should be 404", ->
_r1.should.have.status 404
# GET existent account
Given "I have created the Account", (done) ->
client.post "/account", { userId: 1, accountType: 0, accountCategories: [], beneficiaries: [], accountOwner: { firstName: "Test", lastName: "User" } }, (err) ->
done()
err
When "I request the Account", (done) ->
client.get "/account/1", (err, req, res, obj) ->
_e2 = err
_r2 = res
_d2 = obj
done()
err
Then "it should responond with a document", ->
_d2.should.be.ok
And "it should have the userId 1", ->
_d2.userId.should.eql 1
And "it should have an accountOwner property", ->
_d2.accountOwner.should.be.ok
And "the status code should be 200", ->
_r2.should.have.status 200
当我运行它时，我的输出始终如下：

现在，我知道通过client.get / client.post进行的REST调用几乎是瞬间完成的。当我删除dones并在没有它们的情况下运行时，除了重新启动我的restify服务服务器后的第一次运行时，通常只有第一个或第二个Then / And失败，其余的都成功。有一个时间问题，可能是几毫秒，但绝对不是2000毫秒。我很好奇为什么当我投掷done()电话时，我的Givens和Whens突然开始超时。
我很确定我误解了mocha-cake如何改变coffescript Feature-＆gt; Scenario-＆gt; Given / When-＆gt; Then / And / ... into describe / it calls。我怀疑在某种程度上适用的范围比看起来具有mocha-cake脚本结构的性质要大得多......我只是不确定该范围究竟是什么。

我也不熟悉摩卡蛋糕。我正在使用摩卡/（点燃）咖啡来测试。我发现在promises中包含我的调用很方便，因为最新的mocha是有意识的。然后，我不必为＆＃34;完成＆＃34;而烦恼。另请注意，您可能需要调用res.end（）或res.resume（）（请参阅this explanation）
仅为＆＃34; GET＆＃34;：
Promise = require('bluebird') # or whatever, I presume
port = 8776 # ditto
getHttpJson = (addr)->
addr = normalizeUrl(addr)
new Promise ( resolve, reject )->
req = http.get(addr, _completeResponse(resolve) )
.on( 'error', reject )
req.end()
一般情况：
requestHttpJson = (method, addr, data)->
if data?
data = JSON.stringify(data)
urlBits = getUrlBits(addr)
new Promise (resolve, reject)->
req = http.request(
method: method
headers: {
"Content-Type": "application/json" }
hostname: urlBits.hostname
port: urlBits.port
path: urlBits.pathname
, _completeResponse(resolve) )
req.on( 'error', reject )
if data?
req.write( data )
req.end()
postHttpJson = (addr, data)->
requestHttpJson('POST', addr, data)
putHttpJson = (addr, data)->
requestHttpJson('PUT', addr, data)
deleteHttpJson = (addr, data)->
requestHttpJson('DELETE', addr, data)
将地址分解为组件并添加默认值。 （＆＃34; port＆＃34;是一个全球模块。）
getUrlBits = (addr)->
bits = url.parse(addr)
bits.port = bits.port || port
bits.hostname = bits.hostname || 'localhost'
bits.protocol = bits.protocol || 'http'
return bits
normalizeUrl = (addr)->
url.format(getUrlBits(addr))
解析请求主体的实用程序＆amp;解决。
_completeResponse = (resolve)->
(res)->
body = []
res.on 'data', (data)->
body.push data
res.on 'end', ->
body = body.join ''
content = if body == '' then null else JSON.parse(body)
resolve([res,content])
