java - 如何使用 Selenium 在 Java 方法中初始化另一个 WebElement

Question

我有点担心我面临的小问题。我有一个测试用例，我需要从下拉列表中获取任何值。选择后整个网页会重新加载，我有两个选择。如果出现警告消息，我需要再次单击下拉菜单并选择另一个值。如果没有出现警告消息，只需单击“继续”按钮。下拉列表中的所有值都具有相同的 id，仅结尾不同:

uxMiniFinderVoyageSelect_chzn_o_1
uxMiniFinderVoyageSelect_chzn_o_2
uxMiniFinderVoyageSelect_chzn_o_3
uxMiniFinderVoyageSelect_chzn_o_4

直到 30。我所做的就是所谓的 Random 类，我在其中设置了 1 - 30 的变量

Random random = new Random();
int x = random.nextInt(30) + 1;

现在我用这种方式寻找我的元素

WebElement valueFromDropDown = driver.findElement(By.id("uxMiniFinderVoyageSelect_chzn_o_" + x));

但是，如果出现警告消息并且我需要单击另一个值，我的代码会一遍又一遍地选择相同的值。问题是如何正确且用更少的代码编写单击下拉列表中的另一个元素？完整的类看起来像这样

    public class SomeClassName{

        Random random = new Random();
        int x = random.nextInt(30) + 1;
        @FindBy(xpath = "someXpathExpression") private WebElement dropDown;
        @FindBy(xpath = "someXpathExpression") private WebElement warningMessage;
        @FindBy(xpath = "someXpathExpression") private WebElement continueButton;

public void fillForm() throws Exception{
    WebElement valueFromDropDown = driver.findElement(By.id("uxMiniFinderVoyageSelect_chzn_o_" + x));
    dropDown.click();
    valueFromDropDown.click();
    if(user will see that warningMessage suddenly apppears){
    dropDown.click();
    valueFromDropDown.click(); -> this is where I want to click on another value
    }else{
    contunieButton.click();

引入一个随机返回下拉网页元素的方法，如下所示

public WebElement getDropDownValueRandomly() {
    Random random = new Random();
    int x = random.nextInt(30) + 1;
    WebElement valueFromDropDown = driver.findElement(By.id("uxMiniFinderVoyageSelect_chzn_o_" + x));

    return valueFromDropDown;

}

你的类(class)将是这样的:

public class SomeClassName{

    @FindBy(xpath = "someXpathExpression") private WebElement dropDown;
    @FindBy(xpath = "someXpathExpression") private WebElement warningMessage;
    @FindBy(xpath = "someXpathExpression") private WebElement continueButton;

public void fillForm() throws Exception{
    WebElement valueFromDropDown = getDropDownValueRandomly();
    dropDown.click();
    valueFromDropDown.click();
    if(user will see that warningMessage suddenly apppears){
    dropDown.click();
    getDropDownValueRandomly().click(); -> this is where I want to click on another value
    }else{
    contunieButton.click();
    }
}

public WebElement getDropDownValueRandomly() {
    Random random = new Random();
    int x = random.nextInt(30) + 1;
    WebElement valueFromDropDown = driver.findElement(By.id("uxMiniFinderVoyageSelect_chzn_o_" + x));

    return valueFromDropDown;

}

}

希望这有帮助
