我在这里有一个简单的测试，我希望能工作。这个想法是让幻影在 mocha 的 tdd 中工作。（顺便说一句，我尝试了 node-phantom 和 phantomjs-node 都没有成功。）

nodephantom = require 'node-phantom'
assert    = require("chai").assert

host = 'http://google.com'

phantom = null
page = null

suite "Mocha Node-Phantom Loading Google:", ->

  suiteSetup (done) ->
    nodephantom.create (err,p) ->
      phantom = p
      done()

  test "Google page should load", (done) ->
    phantom.createPage (p) ->
      page = p
      page.open host, ->
        assert.match page.content(), /google/, "Page is loaded"
        done()

  suiteTeardown ->
    phantom.exit()

我执行代码如下：

mocha -u tdd -R tap -b sometest.coffee

我收到以下错误：

1..1

当我从此测试中删除幻像时，它按预期工作。

assert    = require("chai").assert

is_decimal = (val) -> assert.match String(val), /^-?[0-9]*\.?[0-9]+$/, String(val) + ' is a decimal.'
is_hex = (val) -> assert.match String(val), /^(0[xX])?[a-fA-F0-9]+$/, String(val) + ' is a hexadecimal.'

suite "Mocha Minimal Test:", ->

  suiteSetup (done) ->
    done()

  test "Assertions pass", (done) ->
    is_decimal 1.5
    is_hex "0x2fc3"
    done()

  test "Assertions fail", (done) ->
    is_decimal 'dog'
    done()

  suiteTeardown ->
    {}

结果：

$ mocha -u tdd -R tap -b mintest.coffee
1..2
ok 1 Mocha Minimal Test: Assertions pass
not ok 2 Mocha Minimal Test: Assertions fail
  'dog' is a decimal.: expected 'dog' to match /^-?[0-9]*\.?[0-9]+$/

所以我知道我的测试的基本结构是正确的，mocha 很高兴。但是 node-phantom 对此有些不满。

我只想让 phantomjs 在这个框架内工作。谁能帮我？

我问的问题在这里得到了回答：

答案是，如果一个库声明了全局变量，Mocha 就会崩溃。我需要包含一个像这样的 -globals 参数：

mocha -u tdd -R tap --globals location -b sometest.coffee

为了允许 phantom 声明位置变量。

另外，我不得不稍微更改我的代码，因为 node-phantom 不支持 page.content()

test "Google page should load", (done) ->
  phantom.createPage (err,p) ->
    page = p
    page.open host, ->
      page.evaluate( 
        -> return document.documentElement.innerHTML
        (err, result) ->
          assert.match result, /google/, "Page is loaded"
          done()
      )
