visual-studio-2008 - 使用 VS2008 负载测试功能获取无 cookie 会话页面的统计信息

Question

我正在使用 Visual Studio 负载测试工具对网页进行负载测试，但显示结果时出现问题。问题是无cookie会话。每次新用户访问页面时，页面 URLL 都会发生变化，我无法计算平均页面响应时间。可以做些什么呢？

Answer 1

我们将 cookie 移至查询字符串。

在此之前，我编写了一个不区分大小写的 url 验证事件处理程序，它忽略了 Url 的会话组件。下面的一个仅删除区分大小写。

class QueryLessCaseInsensitiveValidateResponseUrl : ValidateResponseUrl
{
    public override void Validate(object sender, ValidationEventArgs e)
    {
        Uri uri;
        string uriString = string.IsNullOrEmpty(e.Request.ExpectedResponseUrl) ? e.Request.Url : e.Request.ExpectedResponseUrl;
        if (!Uri.TryCreate(e.Request.Url, UriKind.Absolute, out uri))
        {
            e.Message = "The request URL could not be parsed";
            e.IsValid = false;
        }
        else
        {
            Uri uri2;
            string leftPart = uri.GetLeftPart(UriPartial.Path);
            if (!Uri.TryCreate(uriString, UriKind.Absolute, out uri2))
            {
                e.Message = "The request URL could not be parsed";
                e.IsValid = false;
            }
            else
            {
                uriString = uri2.GetLeftPart(UriPartial.Path);
                ////this removes the query string
                //uriString.Substring(0, uriString.Length - uri2.Query.Length);
                Uri uritemp = new Uri(uriString);
                if (uritemp.Query.Length > 0)
                {
                    string fred = "There is a problem";
                }
                //changed to ignore case
                if (string.Equals(leftPart, uriString, StringComparison.OrdinalIgnoreCase))
                {
                    e.IsValid = true;
                }
                else
                {
                    e.Message = string.Format("The value of the ExpectedResponseUrl property '{0}' does not equal the actual response URL '{1}'. QueryString parameters were ignored.", new object[] { uriString, leftPart });
                    e.IsValid = false;
                }
            }
        }
    }
}

调用者

public EventHandler<ValidationEventArgs> AddUrlValidationEventHandler(WebTestContext context, WebTest webTest)
{
    EventHandler<ValidationEventArgs> urlValidationRuleEventHandler = null;
    // Initialize validation rules that apply to all requests in the WebTest
    if ((context.ValidationLevel >= Microsoft.VisualStudio.TestTools.WebTesting.ValidationLevel.Low))
    {
        QueryLessCaseInsensitiveValidateResponseUrl validationRule1 = new QueryLessCaseInsensitiveValidateResponseUrl();
        urlValidationRuleEventHandler = new EventHandler<ValidationEventArgs>(validationRule1.Validate);
        webTest.ValidateResponse += urlValidationRuleEventHandler;
    }
    return urlValidationRuleEventHandler;

}

现在我需要做的就是添加

    //add case insensitive url validation for all requests
    urlValidationRuleEventHandler = common.AddUrlValidationEventHandler(this.Context, this);

进入网络测试以获得不区分大小写的调用。请注意，此代码包含以下不适当的行

string fred = "There is a problem";
