如何使用Java验证与selenium WebDriver中的UI选项匹配的下拉选项？

Question

我已经编写了如何从属性文件中读取选项的代码。但我不知道如何验证UI下拉中的相同值。

请任何人帮我一样的代码：

@Test()
public void Filterselection_1() throws Exception{

try {
FileInputStream fstream = new FileInputStream("C:/FilterSection/visualization.txt");
      // Get the object of DataInputStream
      DataInputStream in = new DataInputStream(fstream);
      BufferedReader br = new BufferedReader(new InputStreamReader(in));
      String strLine;
    //Read File Line By Line
      while ((strLine = br.readLine()) != null)   {
      // Print the content on the console
      System.out.println (strLine);
      }
      //Close the input stream
      in.close();
        }catch (Exception e){//Catch exception if any
      System.err.println("Error: " + e.getMessage());
      }

Answer 1

尝试下面给出的代码

1. 我们找到下拉元素
2. 获取列表的所有选项
3. 从选项列表
创建值列表
4. 逐行阅读属性文件
5. 检查值列表中是否存在每一行
6. 如果存在，请从值列表中删除该值
7. 如果不存在，则打印值不存在

8. 如果值列表不为空，即它包含属性文件中不存在的值，则打印消息说明相同。

    @Test()
    public void Filterselection_1() throws Exception{
    try {
       //Find the drop down
       Select select  = new Select(DropDownElement);
   
       //Get all options to a List
       List<WebElement> options = select.getOptions(); 
   
       //Iterate through the list and create a list of String containing all the values
       List<String> valueList = new ArrayList<String>();
       for (Webelement option : options) {
           valueList.add(option.getText());
       }
   
       FileInputStream fstream = new FileInputStream("C:/FilterSection/visualization.txt");
       // Get the object of DataInputStream
       DataInputStream in = new DataInputStream(fstream);
       BufferedReader br = new BufferedReader(new InputStreamReader(in));
       String strLine;
       //Read File Line By Line
       while ((strLine = br.readLine()) != null)   {
           //find whether the value is present in the value list
           if (valueList.contains(strLine)) {
               valueList.remove(strLine);
           } else {
              System.out.println(strLine + "not found in the drop down");
           }
       }
       //Close the input stream
       in.close();
   
       //check if valueList is empty (it will be empty if all the values 
       //in the dropdown are present in the property file)
       if (!valueList.isEmpty()) {
           Ststem.out.println("The following values present in the dropdown are not present in the property file : ");
           for (String s : valueList) {
               System.out.prinyln(s);
           }
       }
   
   }catch (Exception e){//Catch exception if any
       System.err.println("Error: " + e.getMessage());
   } 
   

   }
