java - Selenium 下拉选择不起作用

Question

通过 Eclipse IDE 使用 Java 测试 Firefox。下面是我尝试测试的网站的 HTML 代码:

<td class="selectCommandHolder">
<select id="MainContent_DropDownQueryField" name="ctl00$MainContent$DropDownQueryField" aria-invalid="false">
<option value="ICAO" selected="selected"> ICAO </option>
<option value="IATA"> IATA </option>
<option value="Airfields.Name"> Name </option>
<option value="City"> City </option>
<option value="States.Name"> State </option>
</select>
</td>

默认选项是第一个“ICAO”。尝试让我的测试通过值选择第二个“IATA”。Selenium java 代码如下:

    WebElement searchOption = driver.findElement(By.id("MainContent_DropDownQueryField")); 

    Select searchIATA = new Select(searchOption); 

    WebElement selected_value = searchIATA.getFirstSelectedOption();
    System.out.println("Selected values is "+ selected_value.getText());

    Thread.sleep(1000);
    searchIATA.selectByValue("IATA");

    if (searchIATA.getFirstSelectedOption().getText().trim().equals("IATA")){
        System.out.println("succesfully selected IATA.");
    } else{
        System.out.println("selected value is not IATA, it is:" + selected_value.getText());
    }

出于某种原因，我无法选择 IATA，尽管我相信我正在正确地尝试以它为目标。我的控制台输出如下所示:

Selected values is not IATA, it is: ICAO

我可以打印“allSelectedOptions”，它显示上面的“选项值”列表。我在这里缺少什么？

我认为您的代码中有一些错误，您正在检查 if condition 中的旧值此外，您的下拉值中存在空格，因此它与您的 string 不匹配

按如下方式更改您的代码并尝试 -

searchIATA.selectByValue("IATA");
if (searchIATA.getFirstSelectedOption().getText().trim().equals("IATA"))
 {
  System.out.println("Succesfully selected IATA.");
 }
  else
  {
      System.out.println("Selected values is not IATA, it is: "+ selected_value.getText());
  }

更新了完整代码

    WebElement searchOption = driver.findElement(By.id("MainContent_DropDownQueryField")); 

    Select searchIATA = new Select(searchOption); 

    WebElement selected_value = searchIATA.getFirstSelectedOption();
    System.out.println("Selected values is "+ selected_value.getText());

    Thread.sleep(2500);
    searchIATA.selectByValue("IATA");
    Thread.sleep(2500);
    System.out.println(searchIATA.getFirstSelectedOption().getText());

    if (searchIATA.getFirstSelectedOption().getText().trim().equals("IATA"))
    {
        System.out.println("Succesfully selected IATA.");
    }
    else
    {
         System.out.println("Selected values is not IATA, it is: "+ selected_value.getText());
    }
}
