我想計算的Watir或硒

Question

頁面加載時間這裏的情景：

 
1. Login to a web application with username and password and hit Enter (Start timer) 
2. Load the login page (lap timer split, to mark the time for page load) 
3. Click on a another page (split the lap timer) 
4. Stop the stop watch 

Answer 1

中的Watir任何方法調用返回需要多長時間，所以這是一個簡單的任務。

例如，

b.text_field(:id, 'uid').set username 
b.text_field(:id, 'pwd').set password 
time1 = b.button(:id, 'logon').click 
time2 = b.button(:id, 'movepage').click 
puts "Time One: #{time1} Time Two: #{time2} Total Time: #{time1+time2}" 

Answer 2

有一個新的規格被引入到所有現代瀏覽器。目前谷歌瀏覽器，IE9已經內置，Mozilla正在等待應用已經提供的補丁。

這種新規範被稱爲WebTimings，我寫了一個blog post展示瞭如何使用C＃來訪問它。訪問它的方式是通過javascript，因此可以與所有語言綁定一起使用。

中的JavaScript需要的是

var performance = window.performance || window.webkitPerformance || window.mozPerformance window.msPerformance || {}; 
var timings = performance.timing || {}; 
return timings; 

這將返回一個字典是這樣

/* The dictionary returned will contain something like the following. 
* The values are in milliseconds since 1/1/1970 
* 
* connectEnd: 1280867925716
