我已经创建了此测试脚本来测试网站。问题是，有时我可以单击“编辑”按钮，但有时我会为同一按钮获取NoElementFoundException。我在论坛上搜索了相同类型的问题，并按照建议进行了代码更改，但没有一个对我有用。在所附的图片中，我用红色圆圈圈出了按钮，但我对此表示反对。

最佳答案
发布答案，因为我无法解决如何在注释中放置代码...
该错误表明找不到元素，因此XPath出现问题，或者元素不存在。您可以尝试将元素设为等待条件。
....
WebDriverWait wait = new WebDriverWait(webDriver, 30)
window.findElement(By.id("...")).click();
wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath("//input[@name='title']")))
webDriver.findElement(By.xpath("//input[@name='title']"))
....
