为每个selenium命令获取时间

Question

如何使用c＃代码获取每个selenium命令所花费的时间，意味着我想获得网页为HTTP请求和响应所花费的时间，正如我们在firebug-＆gt; Net-＆gt; HTML中看到的那样，如果我们做任何行动。 请有人建议我如何记录api通话时间。

谢谢， 的Eswar

你可以使用下面提到的代码，它会返回一个包含性能指标的字典。

using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using OpenQA.Selenium;

namespace AutomatedTester.PagePerf
{
    public static class Extensions
    {
        public static Dictionary<string,object> WebTimings(this IWebDriver driver)
        {
            var webTiming = (Dictionary<string, object>)((IJavaScriptExecutor)driver)
                .ExecuteScript(@"var performance = window.performance || window.webkitPerformance || window.mozPerformance || window.msPerformance || {};
                                 var timings = performance.timing || {};
                                 return timings;");
            /* The dictionary returned will contain something like the following.
             * The values are in milliseconds since 1/1/1970
             * 
             * connectEnd: 1280867925716

             * loadEventStart: 1280867926155
             * navigationStart: 1280867925685
             * redirectEnd: 0
             * redirectStart: 0

             */ 
            return webTiming;
        }
    }
}
