Question

我有以下菜单栏，我尝试使用selenium web driver进行测试：

<div class="text-center">
  <div class="btn-group pull-left">
    <button type="button" class="btn btn-default" id="id-home_prevButton" style="min-height:10px;min-width:10px" hidden="false"><span class="glyphicon glyphicon-arrow-left" aria-hidden="true"></span>
    </button><button type="button" class="btn btn-default" id="id-home_nextButton" style="min-height:10px;min-width:10px" hidden="false"><span class="glyphicon glyphicon-arrow-right" aria-hidden="true"></span></button>
  </div>
  <span class="span-title" id="id-home_title">Home</span>
  <div class="btn-group pull-right">
    <button type="button" class="btn btn-default" id="id-home_infoButton" hidden="false"><span class="glyphicon glyphicon-info-sign" aria-hidden="true"></span></button>
    <div class="btn-group">
      <button type="button" id="id-home_dropDownButton" class="btn btn-default dropdown-toggle" data-toggle="dropdown" hidden="false">
        <i class="glyphicon glyphicon-align-justify"></i><span class="caret"></span></button>
      <ul class="dropdown-menu dropdown-menu-right simple-title-dropdown" role="menu">
        <li><a href="#home" id="id-home_menu_homeLink">Home</a></li>
      </ul>
    </div>
  </div>
</div>

按钮ID是唯一的。

单击按钮的Selenium scala代码为：

def wEPrint(description: String, wE: WebElement): String = {
  s"$description = wE.getTagName: ${wE.getTagName}  wE.getText: ${wE.getText}  wE.getSize: ${wE.getSize}  wE.isDisplayed: ${wE.isDisplayed}  wE.isEnabled: ${wE.isEnabled}  wE.isSelected: ${wE.isSelected}"
}

...


log.debug("Find id-home_prevButton")

import org.openqa.selenium.support.ui.WebDriverWait
val waitPrevButton = new WebDriverWait(driver, 20)
val prevButton = driver.findElement(By.id("id-home_prevButton"))
log.debug(wEPrint("prevButton",prevButton))
waitPrevButton.until(ExpectedConditions.visibilityOfElementLocated(By.id("id-home_prevButton")))
log.debug("id-home_prevButton.click")
prevButton.click()

sbt控制台输出是：

Selenium测试代码可以找到该按钮，它显示并启用，visibilityOfElementLocated成功但单击抛出ElementNotInteractableException。

当我在没有selenium的情况下运行应用程序时，按钮可见，我可以点击它，它可以正常工作。

在selenium IDE中单击按钮可以正常工作。用于单击按钮的Selenium IDE Java代码是：

driver.findElement(By.id("id-home_prevButton")).click();

修改

我稍微修改了代码：

import org.openqa.selenium.support.ui.WebDriverWait
val waitPrevButton = new WebDriverWait(driver, 20)
val prevButton = driver.findElement(By.id("id-home_prevButton"))
log.debug(wEPrint("prevButton",prevButton))
waitPrevButton.until(ExpectedConditions.visibilityOfElementLocated(By.id("id-home_prevButton")))
log.debug("id-home_prevButton.click")
//prevButton.click()
//prevButton.sendKeys(Keys.RETURN)
prevButton.sendKeys(Keys.ENTER)

现在异常消息是：

23:30:56.497 [run-main-6] DEBUG com.example.selex.MWLExp$ - Find id-home_prevButton
23:30:56.735 [run-main-6] DEBUG com.example.selex.MWLExp$ - prevButton = wE.getTagName: button  wE.getText:   wE.getSize: (40, 34)  wE.isDisplayed: true  wE.isEnabled: true  wE.isSelected: false

所以现在它说虽然visibilityOfElementLocated成功并且显示并启用了元素，但该元素不可见。

此异常的原因是什么以及如何解决？

感谢您的支持。

Answer 1

使用javascriptExecutor通过嵌入javascript来点击元素。通过使用javascript执行器，我们可以在驱动程序上运行javascript。

$sql = "INSERT INTO user_main (UserName, Password, Email)
      VALUES ('".$client_username."', '".$client_password."', '".$client_email."')";

Answer 2

提及Selenium Advanced User Interaction API例如here：我可以解决这个问题。修改后的硒代码如下：

import org.openqa.selenium.support.ui.WebDriverWait
val waitPrevButton = new WebDriverWait(driver, 20)
val prevButton = driver.findElement(By.id("id-home_prevButton"))
log.debug(wEPrint("prevButton",prevButton))
waitPrevButton.until(ExpectedConditions.visibilityOfElementLocated(By.id("id-home_prevButton")))
log.debug("id-home_prevButton.click")
//prevButton.click()
//prevButton.sendKeys(Keys.RETURN)
//prevButton.sendKeys(Keys.ENTER)
new Actions(driver).moveToElement(prevButton).click().perform()

这解决了这个问题，但我仍然想知道ElementNotInteractableException的原因以及为什么selenium抱怨＆＃34;元素不可见＆＃34;在成功进行v isibilityOfElementLocated测试之后。有什么想法吗？

Answer 3

只需使用隐式等待即可解决此问题，因为网页加载页面完全是其查找元素。

driver.manage().timeouts().implicitlyWait(50, TimeUnit.SECONDS); driver.get("URL");

Answer 4

我也遇到过类似的问题：

String id = element.getAttribute("id");
((JavascriptExecutor)driver).executeScript("$('#id').click();");

Answer 5

我遇到了同样的问题。我通过使用不同的Xpath捕获了相同的元素，并且它工作。我也不知道为什么。以下是我的情况：

//a[contains(text(),'%s')] - ＆gt;没用。

//a//span[contains(text(),'%s')] - ＆gt;工作

这是我的HTML代码：

<a data-gtm-event="mbn-event-link" data-gtm-category="mbn-listing" data-gtm-action="home-category-l0-c3" href="/mua-ban-nha-dat-cho-thue-toan-quoc-l0-c3" title="Bất động sản ">
    <span class="clearfix">
        <span class="category-icon"><span class="icon icon-cat-3"></span></span>
        <span class="category-name">Bất động sản</span>
    </span>
</a>
<span class="clearfix">
    <span class="category-icon"><span class="icon icon-cat-3"></span></span>
    <span class="category-name">Bất động sản</span>
</span>

当元素可见且可点击时，Selenium Web驱动程序无法单击按钮，抛出org.openqa.selenium.ElementNotInteractableException
