javascript - Node.js:如何测试函数

Question

如何测试这样的函数？

app.post '/incoming', (req,res) ->
    console.log "Hello, incoming call!"
    message = req.body.Body
    from = req.body.From

    sys.log "From: " + from + ", Message: " + message
    twiml = '<?xml version="1.0" encoding="UTF-8" ?>\n<Response>\n<Say>Thanks for your text, we\'ll be in touch.</Say>\n</Response>'
    res.send twiml, {'Content-Type':'text/xml'}, 200

我还没有选择任何测试框架。我不明白如何测试这个。

谢谢!

我更喜欢 nodeunit 的轻量级语法，与 request 结合用于发出 HTTP 请求。您将创建一个看起来像这样的 test/test.coffee 文件

request = require 'request'

exports['Testing /incoming'] = (test) ->
  request 'http://localhost:3000/incoming', (err, res, body) ->
    test.ok !err
    test.equals res.headers['content-type'], 'text/xml'
    test.equals body, '<?xml version="1.0" encoding="UTF-8" ?>\n<Response>\n<Say>Thanks for your text, we\'ll be in touch.</Say>\n</Response>'
    test.done()

并从另一个文件(可能是您的 Cakefile)运行它:

{reporters} = require 'nodeunit'
reporters.default.run ['test']
