Java和Selenium：Extreme StaleelementReferenceException

Question

我正在遇到一种staleelementReference侵害，在应用程序中似乎超出了所有原因。它绝对不涉及页面的刷新或重新加载，而只需连续两个访问该元素的操作 - 一键单击和一个断言未选择该元素。

Java/Selenium Code：

this.element.findElement(By.cssSelector("input[type='checkbox']")).sendKeys(Keys.SPACE);
(SPACE is used because when usng click, Selenium claims "ElementClickInterceptedExcpetion - other element would receive the click")

assertThat(this.element.findElement(By.cssSelector("input[type='checkbox']")).isSelected()).isFalse();

这将导致：

org.openqa.selenium.StaleElementReferenceException: stale element reference: element is not attached to the page document

即使我使用制动点在int code上，并缓慢跳过每个步骤。

标记：

<div class="hb-cell hb-cell--autoWidth">
 <input tusenskilletegn="" id="utgift-2-belop">
  <input type="checkbox" id="utgift-2-inkludert">
   <div class="hb-label>
    <label class="hb-label-tekst" for="utgift-2-inkludert"></label>
   </div>
  </div>

尝试访问“标签中的for

this.element.findElement(By.cssSelector("label[for$=-inkludert]")).click();

还

org.openqa.selenium.ElementNotInteractableException: element not interactable

” “在这个地方”。

如果您在click（）函数中遇到问题，则可以随时使用js单击它，

public void clickWebElementUsingJS(WebElement element) {
    JavascriptExecutor executor = (JavascriptExecutor) driver;
    executor.executeScript("arguments[0].click();", element);
}

而不是添加任意线程。陈旧，然后再次找到元素。

private WebElement clickCheckBoxAndWaitToGoStale() {
    final By byCSS = By.cssSelector("input#utgift-2-inkludert");
    // find the element
    WebElement checkbox = this.element.findElement(byCSS);

    // click it
    clickWebElementUsingJS(checkbox ); // or sendKeys(Keys.SPACE) if this doesn't work or you just prefer it

    // wait for the WebElement variable to go stale
    try {
        new FluentWait<>(driver)
                .withTimeout(Duration.ofSeconds(5))
                .pollingEvery(Duration.ofSeconds(1))
                .ignoring(StaleElementReferenceException.class)
                .ignoring(NullPointerException.class)
                .until(ExpectedConditions.invisibilityOf(element));
    } catch (WebDriverException e) {
        // log
    }
    // re-find and return the checkbox to run the assert on
    return this.element.findElement(byCSS);
}
