从 Coded Web Test 中的提取规则中获取结果答案

【问题标题】：Getting result from extraction rule in Coded Web Test从 Coded Web Test 中的提取规则中获取结果

【问题描述】：

我一直在尝试从编码 Web 测试 (VS2008) 中的提取规则中提取结果。我想从 testA 中的标签中提取 URL 并将其提供给 testB 的运行参数。在“yield return WebTestRequest”语句之后，我一直在遍历 testA 的代码。这可能吗？

代码片段：

ExtractAttributeValue();
            extractionRule6.TagName = "a";
            extractionRule6.AttributeName = "href";
            extractionRule6.MatchAttributeName = "";
            extractionRule6.MatchAttributeValue = "";
            extractionRule6.HtmlDecode = true;
            extractionRule6.Required = true;
            extractionRule6.Index = 0;
            extractionRule6.ContextParameterName = "";
            extractionRule6.ContextParameterName = "fifth";
            request2.ExtractValues += new EventHandler<ExtractionEventArgs>(extractionRule6.Extract);
                  yield return request2;

我想通了。通过在返回 WebTestRequest 后直接访问 Context 对象。我使用了 Context 的 TryGetValue 方法。下面添加的代码。我的提取规则名为“firstprj”。如果没有找到 URL，我还可以使用此方法返回的 bool 跳过所有剩余的 WebTestRequest。

        WebTestRequest request2 = new WebTestRequest("http://tramdev/MyProjects.aspx");
        request2.Method = "POST";
        request2.Headers.Add(new WebTestRequestHeader("x-microsoftajax", "Delta=true"));
        FormPostHttpBody request2Body = new FormPostHttpBody();
        request2Body.FormPostParameters.Add("ctl00$cphMain$SM", "ctl00$cphMain$pnlLoadCurtain|ctl00$cphMain$btnSearch");
        request2Body.FormPostParameters.Add("__EVENTTARGET", this.Context["$HIDDEN1.__EVENTTARGET"].ToString());
        request2Body.FormPostParameters.Add("__EVENTARGUMENT", this.Context["$HIDDEN1.__EVENTARGUMENT"].ToString());
        request2Body.FormPostParameters.Add("__LASTFOCUS", this.Context["$HIDDEN1.__LASTFOCUS"].ToString());
        request2Body.FormPostParameters.Add("__VIEWSTATE", this.Context["$HIDDEN1.__VIEWSTATE"].ToString());
        request2Body.FormPostParameters.Add("__EVENTVALIDATION", this.Context["$HIDDEN1.__EVENTVALIDATION"].ToString());
        request2Body.FormPostParameters.Add("ctl00$cphMain$txtProjectName", "");
        request2Body.FormPostParameters.Add("ctl00$cphMain$txtOpenStartDate", "");
        request2Body.FormPostParameters.Add("ctl00$cphMain$txtOpenEndDate", "");
        request2Body.FormPostParameters.Add("ctl00$cphMain$ddlAOR", "--All--");
        request2Body.FormPostParameters.Add("ctl00$cphMain$ddlSubAOR", "--All--");
        request2Body.FormPostParameters.Add("ctl00$cphMain$ddlContact", "0");
        request2Body.FormPostParameters.Add("ctl00$cphMain$lstProjectStatus", "Applied for Charter");
        request2Body.FormPostParameters.Add("ctl00$cphMain$gvPrjSearch$ctl02$txtstatus", "");
        request2Body.FormPostParameters.Add("ctl00$cphMain$gvPrjSearch$ctl03$txtstatus", "");
        request2Body.FormPostParameters.Add("ctl00$cphMain$gvPrjSearch$ctl06$txtstatus", "");
        request2Body.FormPostParameters.Add("__ASYNCPOST", "true");
        request2Body.FormPostParameters.Add("ctl00$cphMain$btnSearch", "Search");
        request2.Body = request2Body;
        ExtractAttributeValue extractionRule2 = new ExtractAttributeValue();
        extractionRule2.TagName = "a";
        extractionRule2.AttributeName = "href";
        extractionRule2.MatchAttributeName = "";
        extractionRule2.MatchAttributeValue = "";
        extractionRule2.HtmlDecode = true;
        extractionRule2.Required = true;
        extractionRule2.Index = 5;
        extractionRule2.ContextParameterName = "";
        extractionRule2.ContextParameterName = "firstprj";
        request2.ExtractValues += new EventHandler<ExtractionEventArgs>(extractionRule2.Extract);
        yield return request2;
        request2 = null;

        // get prjId of first record in project list (href in extracted attribute value)
        bool urlFound;
        object firstProjectUrlObj;
        string prjId;

        urlFound = Context.TryGetValue("firstprj", out firstProjectUrlObj);
