Selenium moveToElement（）读取工具提示不起作用

Question

将无效的文件类型添加到文件上传部分后，验证消息将显示为工具提示，即使在使用moveToElement（）之后我也无法验证工具提示;

以下是我用来使工具提示可见的代码

`driver.findElement(By.xpath(""//input[@type='file']"").sendKeys(invalidLicenseFileType.txt);
Actions actions = new Actions(driver);
actions.moveToElement(//*[contains(@class, 'fieldlabel-content')]).build().perform();`

HTML代码：

<div class="fieldlabel-content">
    <label class="fileinput fileinput--invalid">
    <div class="fileinput-cell fileinput-cell-input">
    <input placeholder="Choose a .license file..." accept=".license" value="" tabindex="0" type="file">
    <div class="fileinput-description">
    File:
    <span class="fileinput-description-file">
    <span class="icon fa fa-file-text-o"></span>
    invalidLicenseFileType.txt
    </span>
    </div>
    </div>
    <div class = "popup popup--theme-error popup--position-top popup--hover" style="top: 131px; left: 399px;">Validation message for uploading invalid file type.</div>
    </label>

Answer 1

我有两个建议来解决这个问题：

<强> First : Using JavaScript

WebElement element = driver.findElement(By.xpath("value of xpath")).sendKeys(invalidLicenseFileType.txt);
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("arguments[0].onmouseover()", element);

在最后一行，代替element，您可以指定要悬停的xpath of your WebElement。

<强> Second : Using Actions

尝试在Actions类中使用 clickAndHold 代替 moveToElement 。

WebElement element = driver.findElement(By.xpath("value of xpath")).sendKeys(invalidLicenseFileType.txt);
Actions actions = new Actions(driver);
actions.clickAndHold(//*[contains(@class, 'fieldlabel-content')]).build().perform();

Answer 2

我认为问题是操作尝试将鼠标悬停在元素上，但该元素尚未显示。 你可以尝试下面的代码

driver.findElement(By.xpath("//input[@type='file']").sendKeys("invalidLicenseFileType.txt");
WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(ExpectedConditions. presenceOfElementLocated(By.cssSelector(".popup--theme-error")));
Actions actions = new Actions(driver);
actions.moveToElement("//*[contains(@class, 'fileinput-description-file')]").perform();

Answer 3

我可以在你的代码中看到一些错误。

<强>代码：

driver.findElement(By.xpath("//input[@type='file']")).sendKeys("invalidLicenseFileType.txt");
Actions actions = new Actions(driver);
WebElement element = driver.findElement(By.xpath("//*[contains(@class,'fieldlabel-content')]"));
actions.moveToElement(element).build().perform();
String toolTipText = driver.findElement(By.xpath("//div[contains(@class,'popup popup--theme-error')]")).getText();
System.out.println("Tool tip text present :- " + toolTipText);

// Compare tool tip text
Assert.assertEquals("Validation message for uploading invalid file type.", toolTipText);

Answer 4

实施以下代码有助于解决我的问题。

 try 
 {
     String mouseOverScript = "if(document.createEvent){var evObj = document.createEvent('MouseEvents');evObj.initEvent('mouseover',true, false); arguments[0].dispatchEvent(evObj);} else if(document.createEventObject) { arguments[0].fireEvent('onmouseover');}";
     ((JavascriptExecutor) driver).executeScript(mouseOverScript,uploadFileInputFieldWebElement);
     Thread.sleep(1000);
     invalidLicenseFileTypeMessag = (String)((JavascriptExecutor)driver).executeScript("return arguments[0].innerHTML;",tooltipWebElement);


} catch (Exception e) {
    exception message;

}
