Question

单击“下拉菜单”中存储的“项目”时，我的Webdriver方法不可靠？

例如，10个测试将通过但是一个将失败（下面列出的示例图像）

我的代码：

    public void selectTitleFromDropdownMenu(WebElement dropdown, String textToSearchFor) throws Exception {
    Wait<WebDriver> tempWait = new WebDriverWait(this.driver, 30);
    try {
        tempWait.until(ExpectedConditions.elementToBeClickable(dropdown));
        List<WebElement> options = dropdown.findElements(By.tagName("option"));
        Select selectDropdown = new Select(dropdown);
        for (int i = 0; i < options.size(); i++) {
            if (options.get(i).getText().equals(textToSearchFor))
                this.wait.until(ExpectedConditions.visibilityOf(options.get(i)));
                selectDropdown.selectByVisibleText(textToSearchFor);
        }
        System.out.println("Successfully selected the following text: " + textToSearchFor + ", using the following webelement: " + "<" + dropdown.toString() + ">");
        } catch (Exception e) {
            System.out.println("Unable to select the following text: " + textToSearchFor + ", using the following WebElement: " + "<" + dropdown.toString() + ">");
            System.out.println("Exception: " + e.getMessage());
        }
    }

即使以下代码失败：

    public void selectTitleFromDropdownMenu(WebElement dropdown) throws Exception {
    Wait<WebDriver> tempWait = new WebDriverWait(this.driver, 30);
    try {
        tempWait.until(ExpectedConditions.visibilityOf(dropdown));
        WebElement mySelectElm = dropdown;
        Select mySelect= new Select(mySelectElm);
        mySelect.selectByVisibleText("Mr.");

元素：

<select class="form-control title ng-touched ng-dirty ng-valid-parse ng-valid ng-valid-required" name="Salutation" ng-model="AddingDelivery.EditingDeliveryAddress.Title" ng-options="salut.id as salut.id for salut in Salutations" required="">
<option class="ng-binding" value="">Please select</option>
<option value="0" label="Mr.">Mr.</option>
<option value="1" label="Miss">Miss</option>
<option value="2" label="Mrs.">Mrs.</option>
<option value="3" label="Ms.">Ms.</option>
<option value="4" label="Dr.">Dr.</option>
</select

构建失败示例：

异常：我看到的唯一例外是超时异常，例如15秒后无法定位元素...

感谢您的帮助

如果我是你，我会在你的测试框架中没有内置的东西时添加一些简单的重试逻辑 - 例如重试失败的测试几次。

简单重试代码的C＃示例，在Java中我猜是相同的：

public void DoWithRetry(Action action, TimeSpan sleepPeriod, int tryCount = 3)
{
    if (tryCount <= 0)
        throw new ArgumentOutOfRangeException(nameof(tryCount));

    while (true) {
        try {
            action();
            break; // success!
        } catch {
            if (--tryCount == 0)
                throw;
            Thread.Sleep(sleepPeriod);
        }
   }
}

我建议尝试以下方法并删除显式等待：

 // when you instantiate your driver
 // this is global across all elements, and you no longer need to wait for one element at a time, i.e explicit waits
 driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

 try {
        Select selectDropdown = new Select(dropdown);
        selectDropdown.selectByVisibleText(textToSearchFor);

        System.out.println("Successfully selected the following text: " + textToSearchFor + ", using the following webelement: " + "<" + dropdown.toString() + ">");
        } catch (Exception e) {
            System.out.println("Unable to select the following text: " + textToSearchFor + ", using the following WebElement: " + "<" + dropdown.toString() + ">");
            System.out.println("Exception: " + e.getMessage());
        }
     }
