【LoadRunner】如何对GIS服务器进行性能测试

1、需求了解

　　首先确定对gis服务器压测的测试范围，形成具体的测试用例，gis平台都是通过网页端的javascript api调用的gis集群服务接口，通过LR录制上一步中的业务操作，找到javascript向gis服务器请求的地址做参数化后形成压测脚本，实现对GIS服务器的压力测试。

2、测试范围

　　ARCGIS性能测试主要范围有三个：ARCGIS生成基础地图服务、空间查询服务、为地图提供数据的服务接口的性能,本文主要对ARCGIS生成基础地图服务性能测试进行介绍。

3、测试工具

　　LoadRunner 11

4、测试步骤

4.1脚本准备

利用loadrunner对地图查询业务进行录制，录制脚本如下：

 Action()
 {
         lr_start_transaction("查询");

     web_custom_request("0_4",
         "URL=http://xxx.xx.x.xxx:xxxx/arcgis/rest/services/xxx/{服务名称}/MapServer/0?f=json",
         "Method=GET",
         "Resource=0",
         "Referer=http://xxx.xx.x.xxx:xxxx/xxxgis/aigis/map.html?module=%E4%B8%9A%E5%8A%A1%E5%88%86%E5%B8%83",

其中主要参数为服务名称、行政代码和geometry，服务名称为系统中的行政区划服务，包括AdminProvince（省级）、AdminDistrict（市级）与AdminCounty（县级）等；where=CODE+like+%{查询地区行政区划码}%25%27（根据具体项目决定）；geometry代表空间查询使用的几何要素。

4.3脚本完善

对地图查询脚本进行参数化、数据准备以及添加判断等。

以上为，GIS项目测试经验总结。
