Selenium学习笔记之外部化相关测试数据---xml

我们也可以用xml来定义一个信息更为丰富的UIMap.xml文件，比如，额外还添加控件所属的页，控件的类型，然后解析构建一个XMLParser类来读取相应的值。

 1 <?xml version="1.0" encoding="utf-8" ?>
 2 <UIMap>
 3   <Object ID="User Name">
 4     <Attributes Locator="userName" Page="Main Page" Type="Button"/>
 5   </Object>
 6   
 7   <Object ID="Password">
 8     <Attributes Locator="Password" Page="Main Page" Type="Button"/>
 9   </Object>
10 </UIMap>

相应的解析xml的代码：

 1     public static String getLocator(String locatorID){
 2         InputStream ins=Thread.currentThread().getContextClassLoader()
 3             .getResourceAsStream(FileConstants.XMLFILE_NAME);
 4         if(ins==null){
 5             System.out.println("Missing UIMap.xml file.");
 6             return null;
 7         }
 8         
 9         DocumentBuilderFactory fac=DocumentBuilderFactory.newInstance();
10         DocumentBuilder builder=null;
11         try {
12             builder = fac.newDocumentBuilder();
13         } catch (ParserConfigurationException pce) {
14             System.out.println("Failing to new DocumentBuilder for runtime exception.");
15             throw new RuntimeException(pce);
16         }
17         
18         Document xmlDoc=null;
19         try {
20             xmlDoc = builder.parse(ins);
21         } catch (SAXException se) {
22             System.out.println("Failing to parse xml file for runtime exception.");
23             throw new RuntimeException(se);
24         } catch (IOException ie) {
25             System.out.println("Failing to parse xml file for runtime exception.");
26             throw new RuntimeException(ie);
27         }
28         
29         XPathFactory pathFac=XPathFactory.newInstance();
30         XPath xpath = pathFac.newXPath();
31         
32         XPathExpression exp=null;
33         try {
34             exp = xpath.compile("UIMap/Object[@ID='"+locatorID+"']/Attributes");
35         } catch (XPathExpressionException e) {
36             System.out.println("Failing to get locator for :"+locatorID);    
37         }
38         Node node=null;
39         try {
40             node = (Node)exp.evaluate(xmlDoc, XPathConstants.NODE);
41         } catch (XPathExpressionException e) {
42             
43             e.printStackTrace();
44         }finally{
45             try{
46                 if(ins!=null){
47                     ins.close();
48                 }
49             }catch(Exception ex){
50                 System.out.println("Failing to load UIMap.xml for runtime exception.");
51                 throw new RuntimeException(ex);
52             }
53         }
54         
55         return node.getAttributes().getNamedItem("Locator").getNodeValue();
56     }

测试代码：

1 selenium.type(UIMapParser.getLocator("UserName"), "seleniumtest");
2 selenium.type(UIMapParser.getLocator("Password"), "seleniumtest");
