线程“主”org.openqa.selenium.WebDriverException 中的异常：未知错误：使用 Selenium Java 的意外命令响应

Question

我在 Eclipse 中使用 Selenium，我经常收到这些错误。

在由于加载状态而出现错误之前，我降级到 chrome 102。现在我面临这个我无法理解的错误。 我正在共享我的控制台和脚本：

Answer 1

要单击元素不，谢谢，而不是visibilityOfElementLocated() ，您需要为elementToBeClickable()诱导WebDriverWait ，您可以使用以下任一定位器策略：

• 使用id ：

   new WebDriverWait(driver, Duration.ofSeconds(10)).until(ExpectedConditions.elementToBeClickable(By.id("birtviewer"))).click();

• 使用cssSelector ：

   new WebDriverWait(driver, Duration.ofSeconds(10)).until(ExpectedConditions.elementToBeClickable(By.cssSelector("button#wzrk-cancel"))).click();

• 使用xpath ：

   new WebDriverWait(driver, Duration.ofSeconds(10)).until(ExpectedConditions.elementToBeClickable(By.xpath("//button[@id='wzrk-cancel']"))).click();

看起来已经引入了一个错误 - https://chromedriver.chromium.org/downloads

Resolved issue 4121: WebDriver command sometimes fails with "unexpected command response"

已在 Chrome 驱动程序版本 104 中修复
